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
