Make observations and conduct experiments to provide evidence that friction produces heat and reduces or increases the motion of an object.
In the final unit of Kindergarten, students explore how forces and how different factors can affect an object’s motion. They explore how objects move in different directions when they are pushed or pulled, and then investigate how changing the strength of a force changes the distance an object moves. Finally, students discover how friction can change motion.
In this unit, students use propeller cars to explore the science phenomena of forces. They investigate action-reaction forces and see if a propeller car travels farther when its rubber band releases a smaller or larger force. Students then explore how friction affects motion by testing how far their car moves after rolling over smooth and rough surfaces.
In this unit, students investigate what makes an object float or sink, exploring the science phenomena of properties of objects that float and sink. This page is a high-level extract of the last lesson in 2nd grade that has students applying their knowledge about the relationship between an object’s properties and its ability to float.
