First official video up: Gumdrop Domes. Super simple project that does a great job introing structures, and other concepts. Below is basic information for the project.
Materials: (Per Group)
Per Dome (Group total)
25 Toothpicks (75)
11 Gumdrops (33)
Construction: 15 min demo, 30 min for build
Test: 5 min per group
Grade Level: 4th-8th
One by one place loads on the domes and observe how the domes react
This activity can be easily made into a design challenge by changing the OBJECTIVE to have students to create their own designs to hold the greatest amount of weight (this would require more materials)
You can substitute the MATERIALS and observe the differences in the structure performance. Suggestions: Kabob Skewers, Spaghetti, Marshmallows.
