Lesson 1 Introduction to Matter:
We learned which tools are used to measure mass and weight. Next we learned that volume is the amount of space an object takes up or occupies. We compared the volume of a bowling ball to a balloon and learned that though their volumes are similar their masses are not. Then we learned why a triple-beam balance is the instrument used to measure mass. Next we learned that mass is the same on the moon as it is on the Earth but weight differs because the force of gravity is less on the moon. Then we reviewed which tools are used to measure mass and weight. Then we were introduced to ways to measure volume. We learned that whether you use a formula or displacement 1 mL of water is equal to 1 cm³.
Assignment: Complete problems to find the volume of a lunchbox and a locker.
