The purpose of this lesson is to introduce the unit on measurement and activate prior knowledge about the topic.

Included is a YouTube video to support Grade 3 Blended Learning Math - Unit 4.0: Measurement - Introduction

A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring.

In this episode of Crash Course Kids, Sabrina uses what she knows about properties of objects to solve the mystery of what she tripped over last night.

Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

Student will choose a three-dimensional object that is of interest to them and calculate its surface area and volume, in both the metric and imperial systems of measurement. Students will then create a scale model of the object.
