Investigate how the centre of gravity of a structure affects the structure’s stability and balance, then test your skills at stacking a dramatic overhang that seems to defy gravity.
MATERIALS
- At least four identical rectangular stackable objects. The size of the object doesn’t matter as long as all of your chosen objects are the same size and type.
- Examples: Jenga blocks, a deck of cards, DVD cases, books, granola bars.
Ergonomic Structures!

Can you create a chair that can hold a load using only paper and tape? Explore what makes a chair strong and stable enough to sit on, and apply learning about what elements lend support, strength, and stability to structures.
MATERIALS
- Paper (8.5 x 11” office paper is fine – you can recycle scrap paper!)
- Scotch or masking tape
- Scissors
- Something to serve as a load to test your structure. It can be a small / medium toy or stuffed animal, or it can be a small can of food.
