5. Building walls
Using all they've learned in this unit so far, the STEMmers are all set to complete their design challenge. Using what they know, their creativity, and the Engineering Design Process, the kids will design a mortar that will help them build a strong, stable wall.
First, each group IMAGINED the possibilities for their mixtures. The groups were able to add up to three scoops of either sand, soil, and clay to include in their mortar mixtures. After imagining individually, the groups then shared and discussed their thoughts. Next, each group came up with a plan for their materials and shared why they thought this mortar would help them build a good wall.
Finally, the groups were given about rocks and their mortar mixtures to build with.
