Force and Interactions
Our third graders in Mrs. Keelan's and Mrs. Kahai's classes are learning about forces and interactions as they explore simple and complex machines.

Day 8, 9, and 10 - Working on our Problem - Our final task is to use the design process to create a compound machine that would rescue a tiger that fell into a ravine. We ASKED, EXPLORED, MODELED, EVALUATED and EXPLAINED our model.
Day 6 & 7 - Build a Compound Machine - Our next task was to combine 2 or more simple machines to complete a task. The picture above is an example of a compound machine. It is a combination of a wheel and an axle and a lever and it is used to carry the blue bundle.
Day 4 and 5 - We continued building our inclined planes using directions from Publisher Viewer (on our iPads) and then we started building levers and pulleys. After each build our students worked together to complete their Launch Log. This involved drawing what they built and reflecting on questions about what they learned.
Day 3 - We finished building our wheel and axle models today and then we learned how to use a new app on our iPads. We started making inclined planes. Here's our wheel and axle creations.
Day 2 - On our second day we reviewed what we knew about Forces, read a book called the Most Magnificent Thing, learned about Simple Machines, and we created a model of a wheel and axle simple machine with the goal of moving a load. Finally we used an iPad to take pictures of our models.
Day 1 - We began by looking at our VEX IQ kits and identifying the different VEX parts that are in the kit. We found these pieces:
