GRAPH- Inquiry 4

Density of air

Directions:

1. Finish calibrating thermometer (steps 9 and 10)

2. Everyone should have completed Qs 4 and 5 on lined paper and STAPLED it to the Inquiry 5: lab sheet.

3. Pick one group member’s paper to continue questions 6, 7, 8, 9, 10, 11. Discuss these Qs and answer as a group. TRADE OFF WRITERS. These conclusion Qs will be a group grade. Write in PEN.

4. Collaborate and compare your graphs (respiration of fish). On the back of the graph, in PEN:

- Interpret your graph- What does it tell us? Include details.

- Write about your OWN graph

CONTENT BLAST! - Temperature and Density

SOLID LIQUID GASI. Describe how the motion of the

particles and the density of a substance change as it is heated.

HOMEWORK DISCUSSION- STATES OF MATTER…

2 ways the states of matter differ from each other?

• Looking at the visual, can you explain why ice floats on water? Use the word density in your answer.

II. Temperature - measure of the ____________ of the molecules of a substance. 

_______ temperature = more _______energy

movement

higher kinetic

III. Matter is ALWAYS in motion…

LIQUID GAS SOLID

• How does the motion of solids, liquids, and gases compare to each other?

A. When matter (solid, liquid, gas) is ________ atoms move ________ and spread out = EXPANSION

- Volume ___________, Density ___________

HEATEDFASTER

INCREASES DECREASES

B. When matter (solid, liquid, gas) is ________ atoms move _______ and closer to each other = CONTRACTION

- Volume ___________, Density __________

COOLEDSLOWER

DECREASES INCREASES
