Unit of Study - Force and Motion

Dear 3rd Grade Families,

Our Focus

In this 3rd grade science unit we will learn how to identify, test, and use cause and effect relationships to explain how an object’s position and motion can change when a force or work is applied to it.

Instructional Approach

Hands on investigations will give students experience in demonstrating and observing how position and motion can be changed when work or force is applied to an object. They will be able to show work being done with using tools such: as pulleys, wheels, balls, ramps, and/or wagons. They will also show force and motion using magnetism and gravity on objects.

Family Support

You can help your child in several ways.

Point out and discuss work being done to accomplish a goal (opening a door, pushing in a chair, lifting a box etc.)
Ask your child to show you how to make some of that work can be made easier (adding wheels or pulleys, pulling with a rope, using a ramp, etc.)
Challenge your child to come up with ways to make their chores easier by using simple tools!
Play games such as "I Spy" and have your child find different forms of work, such as: push, pull, and lift.

Sincerely,

Donna Mullins
