STATION 1. Measuring the volume of solids

Property of Matter Circus:MASS AND VOLUME

OBJECT MASS (g) Volume (ml) Observations

Sand 2

Water 2

Cotton 2

Problem: Is the mass of the object equal to the space it takes up?Hypothesis: (Write a possible answer to the problem)

(don’t need to write this down) Procedure:

1. Measure 2g of either sand, cotton, or water (pick one)

2. Then find the volume of 2g for your chosen object.

3. Repeat step 1-2 for the other two objects.

4. Record your results in the table.

STATION 2. Measuring the mass and volume of solids

Density Circus: ACTIVITY 1Density blocks: Use the cubes from your Properties

of Matter Circus (share with group next to you)1) Make a table in your book with 6 columns –

material of block, mass, volume, density, prediction and results.

2) Calculate the density of each cube and record it in a table in your handout.

3) Make a prediction about which will float and which will sink.

4) Put the cubes in water and record your observations.

5) Explain your results in terms of density- why did they sink or float?

Density Circus: ACTIVITY 2Looking at bread:1) Place half a piece of bread carefully

in the water. Did it float?2) Now crush the other half of bread

into a ball. What do you predict will happen – will it float or sink? Why?

3) Put the crushed piece into water to test your prediction. What did happen? Can you explain why in terms of density?

Density Circus: ACTIVITY 3Density of clay:1) Measure and calculate the density

of the piece of clay. Show your calculations in your book/handout.

2) Cut the clay in half. Make a prediction about its density now and explain why.

3) Measure/calculate the density of the smaller piece of clay and record this in your notebook

4) What happened to the density?

CIRCUS QUESTIONS

1) Properties of Matter Circus How do you measure the following: (Explain and/or provide a

diagram) a. mass of a solid, liquid

b. volume of a liquid, a regular solid, and an irregular solid

2) Density Circus Write a summary paragraph explaining density and the factors

that affect it.

3) Density Challenge How can you make the red water float on top of the blue water

without adding anything extra to them.
