## 4-PS3-1

## Use evidence to construct an explanation relating the speed of an object to the energy of that object.

20 Lesson(s)

#### Students choose between three different experiments to help them understand the difference between scientific evidence and inference.

#### Using what they have observed about water waves & questioning, students continue to develop the vocabulary and begin to understand how waves transfer energy.

#### In this lesson, students use marbles of various sizes to see how collisions can transfer energy from one object to another.

#### In this lesson students participate in an internet search to investigate the definition of energy and discover the two main types of energy, kinetic and potential energy.

#### In this lesson, students work with pennies to develop questions and predict what happens when objects collide.

#### In this lesson, students use a FUN TOY to make observations that speed is related to the amount of energy in an object as well as work with gravitational and elastic potential energy.

#### In this inquiry based lesson, students work with partners to build rockets with balloons, string, and straws. Students work with altering variables in order to observe how energy and speed are related.

#### In this lesson, students work with ice cubes and different colored paper to develop observations in order to prove energy can be transferred from the paper to the ice cube.

Big Idea:

#### In this lesson, students use cardboard tubes to build marble roller coasters.

#### How can you use evidence to describe the relationship between an object's speed and its energy?
