Overview

In these Hero Elementary activities, children investigate what makes objects easier or more difficult to move. They try to build structures that are well-balanced and don’t fall down, and they test their structures with a push.

Science (2015) Grade(s): KG

SC15.K.1
Investigate the resulting motion of objects when forces of different strengths and directions act upon them (e.g., object being pushed, object being pulled, two objects colliding).

Vocabulary

Push
Pull
Collide
Investigate
Result
Motion
Objects
Forces
Strengths
Directions
Refute

Knowledge

Students know:

Pushes and pulls can have different strengths and directions.
Pushing or pulling on an object can change the speed or direction of its motion and can start or stop it.
When objects touch or collide, they push on one another and can change motion.
A bigger push or pull makes things speed up or slow down more quickly.

Skills

Students are able to:

Investigate forces and interactions.
Describe objects and their motions.
Describe relative strengths and directions of the push or pull applied to an object.

Understanding

Students understand that:

Simple tests can be designed to gather evidence to support or refute ideas about effects on the motion of the object caused by changes in the strength or direction of the pushes and pulls.

Scientific and Engineering Practices

Planning and Carrying out Investigations

Crosscutting Concepts

Cause and Effect

Science (2015) Grade(s): KG

SC15.K.2
Use observations and data from investigations to determine if a design solution (e.g., designing a ramp to increase the speed of an object in order to move a stationary object) solves the problem of using force to change the speed or direction of an object.*

Vocabulary

Solution

Knowledge

Students know:

The relative speed or direction of the object before a push or pull is applied (e.g., faster, slower).
The relative speed or direction of the object after a push or pull is applied.
How the relative strength of a push or pull affects the speed or direction of an object (e.g., harder, softer).

Skills

Students are able to:

Conduct an investigation.
Collect and record observations from tests of an object or tool to determine if it works as intended.
Organize information in a usable format.
Analyze data from tests to determine change in speed or direction.

Understanding

Students understand that:

Simple tests can be designed to gather evidence to support or refute ideas about the effects on the motion of the object caused by changes in the strength or direction of the pushes and pulls.
