1. Dye Lab
Molecular Movement

2. Dye Lab Demonstration
Step 1: Obtain a beaker full of hot water and cold water.
Step 2: Let the water settle so that water is still.
Step 3: Use the dropper to add 1 drop of dye into the hot water.
Step 4: Draw a picture of your observations and write down 3 detailed observations in your notebook. (pg 47R)
Step 5: Use the dropper to add 1 drop of dye into the cold water.
Step 6: Draw a picture of your observations and write down 3 detailed observations in your notebook. (pg 47R)

3. Initial Molecular Model
Complete the initial model page 47R. draw a model of what you think is happening with the molecules inside each beaker of water.
Models always include:
Drawings
Labels
Description

4. Watch this maybe it will help.
Which one looks like it is showing the molecules moving faster?

7. Group Model
Create a model of what you think is happening with the molecules inside each beaker of water.
Models always include:
Drawings
Labels
Description

8. Do you know the difference?
Matter Vs Energy
Do you know the difference?

9. What is Matter?
Have a class brainstorm session about where you have heard the term energy, what types of energy you have heard of and what it means

10. What is Energy?
Have a class brainstorm session about where you have heard the term energy, what types of energy you have heard of and what it means

11. Energy or Matter
Sort the cards into two categories:
Energy
Matter

12. Matter - Anything that takes up space.

14. Energy- what makes matter move or change. Ability to do work.

15. There are different types of energy
There are different types of energy. Add the following energy types to your Glossary.
Potential energy
Kinetic Energy
Chemical Energy
Thermal Energy

16. Brain pop video We will show this video 3 times.
First time watch the video
2nd time write the definition of each word
3rd time refine your definitions as needed

17. Potential energy - stored energy
Kinetic energy- energy of motion
Chemical energy - stored in food used to move.
Thermal energy - vibrating atoms cause heat.

18. Which type(s) of energy were involved in the dye lab?
Brainstorm with your group!

19. Matter and Energy
When molecules (MATTER) gain energy they move faster (KINETIC ENERGY) and create more heat (THERMAL ENERGY).
The faster the molecules move the hotter they are!

20. (moves slower) (moves faster) (lower temperature) (higher temperature)
Less Kinetic energy
(moves slower)
Less Thermal energy
(lower temperature)
More Kinetic energy
(moves faster)
More Thermal energy
(higher temperature)

21. Add the words Kinetic Energy and Thermal Energy to your group model.
Models always include:
Drawings
Labels
Description

22. Energy or Matter
Check your cards. Do you need to move some items. Re-sort the cards into two categories:
Energy
Matter

23. Final Molecular Model/CER 47L
Create a model of what you think is happening with the molecules inside each beaker of water.
Complete the CER
*use evidence from the dye lab
*reasoning use both Kinetic and Thermal energy
Models always include:
Drawings
Labels
Description

24. Group brainstorm
What types of energy are involved in the process of the car changing temperature? (Refer to vocabulary chart)
Why do you think so?
Kinetic and thermal energy are the important types of energy to use to describe how our car gets so hot.

25. My creative representation of Kinetic and thermal Energy! Pg. 50L
Draw a picture that represents the movement of particles (kinetic energy) and the average temperature (thermal energy) as it increases. Be creative do not just draw the image on 50R. Give it character and life. Show the kinetic energy and thermal energy relating it to real life.
Remember to include:
Movement and Temperature!

26. Heat Transfer
Is the transfer of thermal energy from a hotter object to a cooler one until both objects are the same temperature.
(You can not transfer cold or give someone cold)
