Shoe shuffle

footwear-june272020.jpg
Your challenge is to pair up all of the shoes, without speaking.
Set Up

Tape a 5-foot line on the floor.

Place 5 pairs of shoes on the floor. Make sure that you shuffle up the pairs and have them some distance from each other. Mix up the shoe types. Try to have a pair of high heeled shoes, a pair of flip flops, sneakers, etc. Mix up the distances from the line so that you have some close and some further away.

Mark one pair with yellow dots and another pair with red dots.

The red dot shoes should be the furthest from the line.

Give each team the following items: 1 broom, 1 piece of string 12”, 1 piece of cardboard, 3 plates, 2 cups, 1 yard stick, 5 unsharpened pencils, 1 piece of yarn 12”, 1 frisbee, and 2 socks.

Procedure

Behind the line, there are several shoes that have been separated from their matching shoe.

 

Your challenge is to move the shoes so that they are paired up with the matching shoe.

 

To be considered paired-up, the shoes must be touching each other.

You have been given materials to move the shoes; you may not use anything else.

You may not talk while solving the challenge.

When moving the shoes, you must be behind the line. You may not change the setup.

The shoes with yellow dots on them must remain in contact with the floor while you are moving them. If a shoe loses contact with the floor, that pair of shoes will be out of play and you may not receive score for them.

The shoes with red dots on them must both be moved behind the line before being paired up.

You have 8 minutes to solve this challenge.

Scoring

Each pair of shoes is paired correctly: 10 points

The pair of shoes with the yellow dots is paired without leaving the floor: 15 points

You will have 5 minutes to solve this problem.

Your problem is to build the longest chain out of the materials provided.

The chain will be held at each end by a team member, so that it does not touch the floor. 

The length for score will be the horizontal distance between the two team members hands.

If the chain breaks then the measurement will be from the hand one end to where it touches the floor

If the two pieces are not the same then the longest distance is measured from hand to floor.

Scoring

Creativity of non-verbal communication: 1-20 points

Creativity of construction of the chain: 1-20 points

Builders and Architects

rz_reno_nightmare-blueprint.jpg
Your challenge is to recreate a structure that you haven't seen, using only non-verbal instructions.

This is a 2-part challenge.

 

Set Up

Teams:

There is a structure hidden behind a screen. This is not visible to anybody during part 1.

There are 2 boxes of materials.

One that can be used to recreate the hidden structure.

Another contains items to use as part of a non-verbal communication system.

Judges:

Build a structure of varying complexity.

Your structure must be hidden from both sub-teams until part 2 begins and then it should only be seen by the Architects when part 2 begins. This can be done by keeping it in a covered box or behind a curtain. 

To build the target structure, use what ever you have easy access to. Lego's work well if you want to keep it simple. To make it more complex, you can use just about anything that you have two of. Build a tower or a bridge or whatever else strikes your fancy.

After you build the structure, hide the structure from view and place the same quantity of the items that were used into the builders' box. 

The communicating tools in the Architects' box could be: A can of soda, a ruler, a non sharpened pencil, a pretzel, an eraser, a ball, a deck of cards, a penny, a nickel, a dime, and a quarter. The team may use all or just some of these items. 

Procedure

Time:

In Part 1, you will have 5 minutes to come up with non-verbal communication method and practice.

In Part 2, you will have 5 minutes to recreate a hidden structure, and demonstrate your solution to the judges.

Rules: 

At the beginning of time, the team will divide members in two sub-teams.

One sub-team will be the “Builders”.

The other sub-team will be the “Architects”.

 

There is a hidden structure that is not visible to either sub-team until Part 2 begins.

At that time, the solution is revealed for only the Architects to see.

 

There are two boxes each with a set of items, which are different for each sub-team.

 

The Builders’ box will have all of the items needed to construct and recreate the original hidden structure.

 

The Architects’ box will have completely unrelated items i.e. with none of the items that will be used to recreate the hidden structure.

 

In Part 1, the two sub-teams may handle the items in each box, but the Architects’ and Builders’ items must not be mixed together.

 

In Part 2, the Architects must communicate non-verbally using only the items provided in their box.

Remember that the Architects must be nonverbal in voice and in body language.

Signaling to the Builders by shaking ones hand or head to give direction will be viewed as verbal body language and

not permitted.

Scoring

Ability to establish a creative means of non-verbal communication: 1-50 points

Accuracy of recreation of target structure: 1- 100 points

Teamwork: 1-25 points

Penalty for speaking during part 2: 1-5 points each infraction

Penalty for communicating without using an item from the Architects' box: 1-5 points each time

Debriefing

Were team member tasks and responsibilities sorted out clearly?

Were team members appropriately divided into sub-teams?

Did the architects use communication items and other non-verbal methods effectively?

What would the team do differently if they did it again?

Switch teams and redo the solution in a different configuration, or change out some of the props. The builders may ask questions directed to the architects at anytime but don't let them know this unless they ask.

The architects team must be warned every time they communicate without the use of the tools provided.

Chip Flip

Your challenge is to flip the chips in the target area so that the numbered sides are face up on the colored circles.

Teams:

In front of you is a 6-foot square target area with 15 poker chips placed with a numbered side down on colored circles whose numbers match the number on the chip.

Materials: 2 straws, 1 ruler, 1 yardstick, 4 sticky labels, 1 small paper cup, 1 eight-foot length of string, 1 small magnet, 1 envelope, 3 toothpicks, and 2 pipe cleaners.

Judges:

Materials: Construction paper, push pins, masking tape, or pavement chalk.

Number 15 poker chips on ONE side only, 1-15. (using a Sharpie.)

For a carpeted surface, cut 15 four-inch diameter circles out of construction paper, and pin them into the carpet.

For a hard floor, tape the colored circles, or for garage floor color the circles directly on the surface with chalk.

Number each circle, 1-15.

Mark a six-foot square target area around the circles with masking tape.

Place one chip, numbered side down, inside each circle, matching numbers.

Procedure

Time:

You have 6 minutes to solve this challenge.

Rules: 

Using only the materials given, you must flip the chips in the target area, so that the numbered sides are face up on the colored circles.

Team members may not enter the target area.

No part of a team member's body may enter the target area.

Team members may not touch the chips directly. If a chip is touched, it will be removed by the judge and receive no score.

 

You will be scored at the end of 6 minutes or when you decide to stop.

Scoring will be based on the total number of points received, minus any penalty points for a chip touching a circle not its own.

NOTE: Team members may remove the chips from the target area and return them again, provided they do not touch the chips, but DO NOT tell them that unless THEY ASK!

Set Up

Teams:

There are three bowling setups on the floor in front of you.

There is a 5ft long release line, taped on the floor.

You have 15 balls, plus a series of materials, with which to make launching devices.

Judges:

Materials: 30 roughly identical small water or soda bottles

Provide 15 balls. Golf balls and tennis balls would probably work the best.

Give the teams the following materials: 1 broom, 1 yardstick, 2 soup cans, 5 cups, 10 rubber bands, 1 dowel rod, 1 shoe, 1 coat hanger, 2 pieces of string 12", 36" of masking tape, 5 sheets of paper.

On the third setup put stars on all but the middle bottle.

Place dots on the floor for the locations of the water bottles.

Procedure

Time:

You will have 7 minutes to solve this problem. You can ask questions, but time will continue.

Rules: 

There are three bowling setups on the floor in front of you.

Your challenge is to create a device or devices that will allow you to launch balls toward the bowling pins.

There are materials for you to make your devices; no other materials may be used. You may not alter the setup.

 

When launching the balls, you and any device used must stay behind completely behind the release line. Any attempt made where your body or the device crosses the line will NOT count. You may NOT launch the balls using any part of your body directly.

You will have 15 balls. You may not retrieve the balls once you launch them. You may make as many attempts at each setup as you like and you do not have complete them in order nor do you have to complete before moving on to another setup.

Some of the pins have stars on them. These pins must not be knocked over.

Pins without stars should be knocked over.

 

To be considered knocked over the pin must be lying on its side.

NOTE: If a team member crosses the line, try to tell them before they launch the ball.

Scoring

Each pin correctly knocked over will receive 5 points

Each pin correctly standing will receive 5 points

Each setup that is completed totally correct will receive 10 bonus points

Creativity of how the balls are launched 1-25 points

Teamwork 1-15 points

Debriefing

Were team member tasks and responsibilities sorted out clearly?

Did the team use the materials effectively?

What would the team do differently if they did it again?

Was it better to complete one setup before attempting another?

Which set-ups had the biggest risk, biggest reward?

Mixed part tower

Your challenge is to make parts and assemble them into a structure that stands as tall as

possible.

You have 8 minutes to solve the problem. The judge will warn you when 2 minutes and when 1 minute remains. You can ask questions and talk to each other at any time.

Your challenge is to make parts and assemble them into a structure that stands as tall as possible.

 

You have materials to use to create the parts of your structure. The scissors may not be a part of your structure. Nothing else can be used.

Each part used in the structure must have four sides. At least two of the sides must be made from different

materials.

The sides can be different in length. They do not need to be squares or rectangles.

 

You may use materials to assemble the four-sided parts in any way. However, only the parts will be considered when scoring the height.

 

Your structure must rest on the table. Nothing may touch it when it is being measured.

You can ask to be scored at any time. The challenge is over when you ask to be scored or when time ends.

For Judges Only:

Parts cannot share sides, meaning one side cannot serve as a side for two shapes.

The sides do not need to be completely connected.

Materials used to make connections do not qualify as a second material unless it is also used to create a side. However, a square made of toothpicks could have one side covered with a mailing label and be allowed.

Scoring

You will be scored as follows:

Each four-sided part used in your structure will receive 1 point.

Your structure will receive 2 points for every inch of height above the table surface.

If your structure stands more than 12 inches above the table you will receive a bonus score of 20

points.

You will receive 1 to 10 points for the creativity of your solution.

You will receive 1 to 10 points for how well your team works together.

Debriefing

Were team member tasks and responsibilities sorted out clearly?

Did the team use the materials effectively?

Was time used effectively?

What would the team do differently if they did it again?

Was it better to focus on numbers of parts or height?

Hanging around

Your challenge is to hang as many items as possible so they are supported by the piece of string.

Set Up

Be sure to set up the site so a string is firmly in place and is between 5' to 8' long and approximately 30 inches above the floor. The string should be as close to level as possible. We suggest tying it to the legs of two tables or two chairs. Be sure the string cannot slide down. 

Give each team the following items to hang for score:

7 coins

6 pencils

5 Ping Pong balls

1 softball

 

Give each team in all divisions the following materials to use to hang the items:

5 plastic straws

1 sheet of paper, 8.5" x 11"

3 small cups, 4 - 6 oz.

3 small rubber bands

6 pieces of yarn,12" long

1 envelope

*The yarn should be sturdy and may be twine, or something else that won’t easily break.

For Division II teams add the following:

1 small rubber band

2 paper clips

For Division I teams add to the following to what is provided to Division II teams:

3 paper clips

2 pieces of masking tape, 12"

1 sheet of paper

1 small rubber band

2 small cups

Procedure

You have 8 minutes to solve the challenge. The judge will warn you when 2 minutes and when 1 minute remains. You can ask questions and talk to each other at any time.

 

Your challenge is to hang as many items as possible so they are supported by the piece of string.

 

You cannot change the setup.

 

On the table are materials to use to hang the items and a container holding the items. The container cannot be used in your solution and nothing else can be used.

 

You cannot use any single material, such as a straw, to hang more than two items onto the string. However, you may use the other straws to hang up to two items each.

 

Items must not touch anything except the string or materials or both.

 

Items must be held in the air on the string when time ends to count for score.

 

You will receive bonus score for each different method you use to successfully hang an item.

 

You can ask to be scored at any time. Competition is over when you ask to be scored or when time ends.

For Judges Only:

If more than two items use the same material (all or part) to be connected to the string, score only the two highest value items that use that material. The same material does not mean the same type of material, such as cups, it means the same exact material, such as a particular, single cup. Teams may duplicate methods. For example, they may use different paperclips to hang two cups that contain two items as long as they are independently connected to the string. This would score for four items but only one method. Using a cup in a different way would be a different method.

You will be scored as follows:

Each Ping Pong ball successfully hung will receive 2 points.

Each coin successfully hung will receive 3 points.

Each pencil successfully hung will receive 5 points.

Stack 'em

Your challenge is to use the items to stack your cups on top of the table.

This is a two-part challenge.

Set Up

Set up the competition site by taping a 6-foot long line on the floor that is 3 feet away from one side of the table running parallel to it.

Place 25 unmarked cups of the same type on the table, and a set of the following items behind the taped line:

2 paper plates

2 unsharpened pencils

4 rubber bands

6 adhesive mailing labels

3 pieces of string, 12"

2 sheets copy paper

10 paper clips

2 cubes of clay, 1”

In a separate pile, place the following items:

1 plastic ladle or large spoon

1 baseball cap

1 yardstick

1 broom

The teams can use these in their solution but they may not be altered or damaged in any way.

Procedure

This is a two-part challenge.

In Part I, you will have 2 minutes to discuss the problem, create a solution, and practice.

In Part II, you will have 5 minutes to test your solution for score.

 

You will be warned when 1 minute remains in each part. You may ask questions and talk to each other at any time.

There are cups on the table and a series of items behind the taped line the team can use use these items to solve the challenge.

 

Your problem is to use the items to stack your cups on top of the table.

 

You may practice as you wish in Part I. When Part I ends, you must move all of the cups behind the line on the floor. You may leave materials where you have placed them or you may take some or all of them behind the line.

 

In Part II, you must stand behind the line when stacking the cups for score. You cannot change the line. 

You must move the cups one at a time. 

 

You are allowed to cross the line to retrieve items and cups.

 

When you are across the line, you must retrieve anything you touch.

 

You will be finished when time ends or when you tell the judge you would like to be scored. After that, you cannot touch any cups or items.

For Judges Only:

When Part I ends, let the team move cups and items behind the line before you start the timer for Part II.

In Part II, make sure any team member involved in moving a cup for score is standing entirely behind the taped line; however, they can break the plane of the line.

You will be scored as follows:

Every cup that rests on the table will receive 1 point.

The three tallest stacks will receive 1 point for each inch it is tall.

You will receive 1 to 10 points for the creativity of your solution.

You will receive 1 to 10 points for how well your team works together.

For Judges Only:

Check the ramp before each team competes. Make sure the team does not place it anywhere past the foul line. Use molding that allows the balls to travel down them accurately.

Team members must stand behind the foul line while a ball is in play. If for some reason a team member drops a ball before rolling it, or a ball is rolled but falls off the ramp before hitting the table, that ball can be picked up and rolled again.

Procedure

This is a two-part challenge.

 

In Part I, you will have 3 minutes to discuss the challenge, create a solution, and practice.

 

In Part II, you will have 3 minutes to test your solution for score. You can ask the judges questions, but time will continue. The judge will warn you when 1 minute remains in each part.

 

There is a table with a chessboard taped to it. There is a taped foul line, and behind the foul line there is a ramp and a bucket of 10 balls.

 

Your challenge is to roll the balls down the ramp and knock over the black chess pieces while leaving the white chess pieces standing. If you can knock over the black King without knocking over any white chess pieces you will get a bonus.

 

You have four pieces of wood to use. You can place the wood anywhere on the table or on the chessboard.

you wish in Part I. When Part II begins, you will place the pieces of wood anywhere you want on the table. They will stay in place for the first three rolls. Then you can change their position for the next three rolls. You aren’t allowed to use them for the last four rolls.

 

You can move the ramp between rolls if it is always completely behind the foul line. You are only allowed to roll each ball one time. You are not allowed help guide or move the ball after it is released down the ramp.

 

After each ball comes to rest, a judge will remove all knocked-over chessmen and will also remove the ball from the course.

 

You do not need to roll all the balls and may stop at any time. Otherwise, you will be scored when time ends or after all the balls have been rolled.

Scoring

You will be scored as follows:

For each black chess piece that is knocked over you will receive 2 points.
For each white chess piece that is knocked over you will lose 2 points.
If you can knock over the black king but not knock over ANY of the white pieces you will receive 15 bonus points
You will receive 1 to 15 points for how well your team works together

Tornado Trouble

Your challenge is to keep as many items as possible inside a scoring area while a fan blows on them from different distances

This is a two-part challenge.

Set Up

Set up the competition site as shown below, with a 4 foot x 4  foot taped scoring area and four lines to mark fan placement. The first fan line should be 24” away from one side of the scoring area and the other lines should each be 24” apart. Starting from the one closest to the scoring area, mark each line with a score value in this order: 8, 6, 4, 2.

 

Place a set of the following barrier materials on the table:

6 blocks of different sizes ranging from 2 x 2 to 2 x 6

12” masking tape 

1 paper plate

1 paper napkin

4 small wooden dowels

 

Place the following items in a box marked “scoring items”:

2 cotton balls

1 hollow plastic ball

1 plastic cup

1 ping-pong ball

1 tennis ball

2 6” pieces of string

4 marbles.

 

Give the team one card marked “STOP.”

 

Have a working box fan on the floor at the line farthest away from the scoring area. Move it to the next line during Part II and let it run for 10 seconds. Be sure to set the fan speed to “high.” Plug the fan into an extension cord that has an on/off switch. Instruct the team to use the switch when practicing with the fan

Screen Shot 2022-09-13 at 10.34.18 PM.png
Procedure

This is a two-part challenge.

In Part I, you will have 5 minutes to discuss the problem, create a solution, and practice.

In Part II, you will have 2 minutes to test your solution for score.

You are allowed to ask the judges questions, but time will continue. The judge will warn you when 1 minute remains in Part I.

 

Your problem is to keep as many of the scoring items as possible inside the scoring area while the fan blows on them from different distances You are not allowed to alter or damage the fan.

 

You will be given barriers to use in your solution. You are allowed to place them anywhere on the site, but they are not allowed to touch any of the items when Part I ends.

 

When practicing in Part I, you are allowed to turn the fan off and on, but you are not allowed to touch it in any other way

 

Part I is over when you tell the judges you are ready to test your solution or when Part I time ends.

 

In Part II, a judge will turn on the fan and let it run for 10 seconds from each of the lines, starting with the furthest one and then moving the fan toward the line nearest to the scoring area.

 

You have one STOP card.

If you want to move any of the barriers during Part II, hold up your STOP card. You can raise your card at any time, but if the fan is blowing, you must wait until it stops to move the barriers. Any barrier that you move is not allowed to touch an item. When you are finished, lower the card, and the judge will turn on the fan at the next line. Time continues.

 

Competition is over after the judge runs the fan for the fourth time, or when there are no items left in the scoring area, or when Part II time ends.

For Judges Only:

Make sure the barriers are not touching any of the items when Part I ends. If they are, allow the team to adjust them in a timely manner.

If the team raises its STOP card, the team can move its barriers, but make sure that they do not move the barriers so they are touching any of the items.

Items can touch the barriers if they are blown into them, but not at the beginning of Part II, and the team cannot move a barrier in Part II so it touches an item. For example, if a marble rolls into a block when the fan blows and is touching it when Part II ends, count it for score. However, if the team were to place tape directly onto the marble, it would not count for score.

Scoring

You will be scored as follows:

Each item left in the scoring area will receive 15 points.

Each item blown out of the scoring area will receive the point value of the line that the fan was blowing from.

You will receive 1 to 15 points for the creativity of your solution.

You will also receive 1 to 10 points for how well you work together.
