In lesson 1.2, the lesson calls for 3 cherries. Here are the options for teaching the lesson this year.
Work with your building to purchase cherries or a small jar of olives that you think will be the right size for their pitters.
Use the slide GIFs as the demonstration, or this fun video!
Use this modified version of the slides ; it doesn't match the "mystery machine" component but it does fulfill the process of observing the parts of a simple machine.
