The document describes designing a container to keep a popsicle frozen for at least 60 minutes when exposed to the outside sun. Students will work in groups to brainstorm ideas, plan a design using available materials like straws and tape, build their container, and test how long their design keeps a popsicle frozen.

1. Keep it Cool!
Being outside all day in the summer, at the beach, is fun, however, it
is also HOT! Wouldn't a frozen popsicle be wonderfully refreshing?
The problem you face is that you do not have a cooler in which to
store your popsicle and the freezer at your beach house is just too far
away to walk to for the refreshing treat.
Groups will design a container that will keep a popsicle frozen when
it is exposed to the outside sun for a minimum of 60 minutes.

2. Investigate :10
• Students will work at table groups.
• Groups should look over the available
materials.
• Determine the properties of each of the
materials.

3. Brainstorm :10
You will build an apparatus to keep your
popsicle from melting. 10”x7/8”x1/2”
Brainstorm ideas for your popsicle keeper.
• Brainstorm ideas, explore at least 10 total
ideas.
• Discuss as a group.

4. Plan a Design :15
• Groups will collaborate and create drawings of
their best design options
• You may take parts of everyone's ideas to
create one or two designs.

5. Build :20
• Work as a team to build your Popsicle
Keeper.
• Try to follow your plan, but it is ok to
diverge!

6. Don’t Make a Splash!
Water balloons can be a lot of fun to play with outside in the summer
heat. However, if they drop before they are supposed to, they break
and spoil the fun. Your challenge is to design a device out of straws
and masking tape that will keep a single water balloon from breaking
when dropped from a fixed height .
Groups will design a device to protect a water balloon.

7. Investigate :05
• Students will work at table groups.
• Each group will be provided with a bag of 30
straws and 1.3 meters of 1" masking tape.
• Each team will also be given two water
balloons. The final design will be placed in a
zipper type sandwich bag.

8. Brainstorm :10
You will build an apparatus to keep the
water balloon intact when it is dropped.
Brainstorm ideas for your balloon keeper.
• Brainstorm ideas, explore at least 10 total
ideas.
• Discuss as a group.

11. Test :20
• Team balloons will be dropped to
determine the effectiveness of the
Balloon Keeper.
