P.2.5: Students will demonstrate an understanding of the properties of matter.

Compare the weight of solid objects and the volume of liquid objects. Analyze and communicate findings.

Teacher's field guide

What Students Need to Do: Students use a balance to compare the weight of solid objects. They measure liquids in marked cups, compare the amounts, and explain what they found.
What Mastery Looks Like: A student can use a balance to tell whether a rock or an eraser is heavier. They can measure two pours of water, name which has more, and point to the readings as evidence.
Common Misconceptions: Students may think a larger solid must weigh more. They may think water that sits higher in a narrow cup is always a larger amount, or mistake cup size for the amount inside.
How to Assess It: Show a picture of a balance with the rock side lower than the eraser side, alongside cups marked 40 mL and 60 mL. Ask, "Which solid weighs more? Which cup has more water? What evidence tells you?"

Lesson moves

Have pairs use a pan balance to compare a rock and eraser, then a marked measuring cup to compare two pours of colored water.
Pour 100 mL of water into a tall cup and 100 mL into a wide cup, then ask, "Does either contain more water? How do you know?"
Give pairs cards showing tipped balances or marked cups; have them name the heavier solid or larger liquid amount, then check the backs.
At a pretend grocery stall, weigh two apples and measure two cups of water, then label the heavier apple and larger drink.
