Check the Educator Guide for detailed materials prep information. Here a couple of other key reminders:
- It will take about 25 minutes to prepare for this activity
- Post the EDP Poster
- Get the Duo Message ready
- Post Testing Results chart and add an Impact column (pp. 46, guide)
- Set up the Materials Table
- Fill two containers with 100 washers each and tape lids on
- Prepare demo glove with 5 spaghetti pieces
- Set up testing stations (skewer taped to aluminum tray, spaghetti, testing weights, ruler).
EDP Steps Used In This Activity
Youth explore how well different materials protect against impact.
For ELL, pair youth purposefully to encourage the best possible environment for collaboration
Emphasize the analogies:
- The spaghetti represent bones in a hand
- The skewer represents a tool
- The washer container represents a falling rock

End of Activity Engineering Reflection
Today we asked which materials are better at protecting against impact. We tested and compared the results to answer our question.
Key Take Away
We can identify which materials to use in making a glove that protects against impact.
Did you know?
Some construction gloves have rubber tread like a shoe to protect workers from impacts with falling tools, construction materials, and the moving parts of equipment.
