Flicking with Forces

Third Grade Science

Here are pictures from our first science unit -- Forces & Interactions. The lesson is called "Flicking with Forces."  Students predict and observe what happens when force is applied to an object, and compare the relative effects of a force of the same strength on objects of different weights by flicking the pink pong ball gently with a finger and measuring the distance the ball covered with a ruler. Students will repeat this procedure using a harder flick. The learning target is Newton's Second Law of Motion - Forces cause changes in the speed or direction of the motion of an object. The greater the force places on an object, the greater the change in motion. 

This lesson is from Livebinder aligned to the Next Generation Science Standerds (NGSS).

Third graders record the results of their experiments.
