Science is one of my favourite subjects to teach. Although I love Language Arts, I really enjoy teaching math and science because students have so many opportunities to take part in fun, engaging, and educational activities that allow them to discover concepts and investigate different ideas.
As Elita previously mentioned, we have created another science unit to address the Ontario science curriculum when teaching a combined grade 4/5 class.
The following investigative activity is part of that unit, but it would be a great activity to use with students from grades 4-8 either as a way to introduce or review simple machines and motion. I think it will be a fun way to review some key concepts with my grade eight students before we delve into systems in action and students design, build, test, and present their own devices.
In this activity, students will work in small groups to investigate both simple machines and linear movement. The activity begins as a whole class activity where simple machines are discussed, to a small group investigation. First, students will examine the car and layout of the experiment to investigate several simple machines. Next, in order to observe linear movement, the car will be allowed to travel down a ramp. Finally, students will demonstrate how changes to the mass of the cart will then affect its linear movement.
