Hands-On Spontaneous Problem:
TREASURE STRUCTURE
(1) This is a two part problem. In Part 1, you will be given 5 minutes to build a structure or structures and practice your solution. In Part 2, you will be given 2 minutes to test your solution and accumulate additional score.
(2) Your problem is: to create a
structure that will span a distance, hold a container and as many jewels as
possible.
The 6, 8 and 10-inch distances are marked on the table with pairs of tape strips. Your
structure must span one pair of taped lines, either the 6, the 8 or 10 set, for score in
Part 2. The structure must begin behind one of the pair of lines and end on the far side of the second line that is part of the same pair of lines.
You may practice with the container and glass jewels during Part 1. The
container may remain on your structure at the end of Part 1; however, no jewels
may remain in the container. You may not break or alter the container or jewels
in any way.
(3) Your scoring will be as follows:
|
6 |
8 |
10 |
Structure spanning the distance |
5 points |
10 points |
15 points |
Each jewel in container for 2 seconds held within spanned area |
1 point |
2 points |
3 points |
|
|
|
|
Supporting the container on the structure for 2 seconds |
5 points |
||
Team work |
1-15 points |
For Judges Only:
Give each team the following materials:
2 pieces of 8.5 X 11 construction paper
10 pieces of spaghetti
6 straws
2 paper clips
8 tooth picks
2 sticky labels
12 inch piece of string
1 small container, such as a small Tupperwareฎ or margarine container
60 Jewels such as marbles, heavy glass beads or rhinestones, or even poker chips (or gum drops, which the team could eat if they wash hands before beginning the problem!)
Setup: .Before the team enters the room, mark out the distances of 6, 8, and 10 inches with 6 pieces of tape across the entire width of a 6 table. Mark 3 Xs with the tape between each of the 6, 8 and 10 strips to indicate the area that needs to be spanned. You should also write on the X 6 area, 8 area or 10area. Or use colored paper in between the tape strips to indicate the different areas. You should write on the paper 6 area, 8 or 10.
As you read the problem indicate the marks for the 6, 8, and 10 inches. Also demonstrate the loading of a jewels in the container and where the structure may not touch.
Make a reasonable allowance for the two-second time limit
a stopwatch is not
necessary, but the container must hold the jewel for a count of 2 before the
next one is added. If the team seems to be adding jewels too quickly, ask them
to slow down.
Scoring chart:
Teamwork 1-15pts |
Distances spanned: 6(5pts)/ 8(10pts)/ 10(15pts) |
Supporting container: 5 pts |
Each jewel held for 2 seconds: 6(1pt X # held) / 8(2pts X # held)/10(3pts X # held) |
