We've embarked on a quest to learn all we can about inventions! So far, we've learned about simple machines, compound machines, and biomimicry.
Students researched compound machines and created their own! Compound machines include two or more simple machines at work. This assignment required partners to solve a problem using a combination of simple machines. Student designs included a safer bicycle with a seatbelt, an elephant-shaped personal crane, and a portable lever on wheels.
Each 4th grader was given a wind-up toy to deconstruct and put back together. Students observed and drew each tiny gear, wire, screw, and nut in order to reconstruct a working toy!
The class went on a nature walk to observe different kinds of trees as a part of our biomimicry lesson. Each student chose two trees to sketch and take notes about. On our walk, one student collected all the different kinds of seeds she found – maple seeds and three varieties of pinecones! Students will use these observations to create a tree-inspired invention involving biomimicry.
Two biomimicry inventions – dentures for eating apples (inspired by sharp animal teeth) and roller skates with springy mushrooms to prevent you from falling.
