Write a procedure on how your special effect is done
Write an explanation on how the special effect works, including the chemistry behind it
Due date: Thursday, September 13

4. Day 1: Elements and Compounds
Learning Objectives:
Observe a demonstration to see how a compound is decomposed into its 2 elements
Perform gas tests to determine their identities
Determine chemical formula of a compound
Compare the properties of the compound to those of the elements it makes up
Practice safe laboratory techniques

5. Starter
Matter is the name for all the “stuff” in the universe. Anything that has mass and takes up space is matter
How many different types of matter are there?
What makes up matter?
Look around and list 10 examples of matter in the classroom
Classify your examples as pure substances or mixtures
For the ones that are mixtures, what do you think is in them? (What is it that makes them up?)
Time: 15 minutes

6. Activity One: Video

7. Activity Two: Decomposition of H2O2
That video showed the breakdown of water into the two elements that it makes up:
2H2O O2 + 2H2
We do not have the equipment to do this decomposition reaction, but we can do it with hydrogen peroxide (H2O2)
What do you think H2O2will break down into?
We will test for hydrogen and oxygen gas
Time: 30 minutes

8. Activity Three: Demonstration
In the test tube, there is zinc (Zn) and hydrochloric acid (HCl)
What gas do you think will be produced from a chemical reaction between these materials?
Zn + HCl ???
Time: 15 minutes

9. Activity Four: Closing Activity
What are some other compounds that you know? Can you write the names and formula for them?
What does the chemical formula tell us about the make up of the compound?
Can all compounds be decomposed into their elements?
What techniques can be used to do this?
What are elements made of?
What are atoms made of?
Time: 15 minutes

Preparing for the chapter challenge
Due on Wednesday

11. Day 2: States of Matter Learning Objectives:
Describe the particles in different phases of matter, and as the material changes phases
Observe the change in state of water
Graph the phase changes of water
Describe the phase changes with regard to transfer of energy
Characterize materials by their unique phase-change temperatures
Practice safe laboratory techniques

12. Starter

13. Starter Draw 3 circles to represent each state of matter
In the circles, draw what you think the particles look like in a solid, liquid and gas
Describe what the particles do in each of the three phases
Time: 10 minutes

14. Activity One: The Heating Curve for Water
We will investigate how the temperature changes when ice melts (pg )
What is a phase change?
What will happen to the system as we increase the temperature?
Will the temperature not change at any point?
What will happen to the energy in the system as temperature is added?
How will we record the data collected?
Time: 45 minutes

15. Activity One (cont’d) Procedure:
In your group, set up your lab equipment like the picture
You will record the temperature every 1 minute. Make sure the thermometer does not touch the bottom of the beaker
Continue to collect the temperature until the water is boiling and you get the same temperature 5 times in a row.

16. Activity One (cont’d) Data Collecting
Create this table to write down your observations
Data Table 1: Temperature Change of Ice

Temperature (C)
Observations 1 2 3

17. Activity Two: Interpreting Our Data
Lab Report: CERR Model
What to include?
Claim
Evidence
Reasoning
Rebuttal
Due Date: August 28

18. Activity Three: Phase Changes
In your group, create a visual representation of phase changes
Include:
The different phases, and what the changes are called
Is heat energy transferred to or away from the object?
Is it endothermic or exothermic?
What happens to the particles in the substance?
Time: 15 minutes

20. Day 3: Solutions, Suspensions & Colloids
Learning Objectives:
Explore different ways materials can be mixed together to form new materials
Test some materials to see what kind of mixtures they are
Determine why certain kinds of mixtures are manufactured for commercial use in particular ways
Use different methods to separate mixtures

21. Starter
Lots of different things happen when materials are mixed together
Each mixture has its own characteristics
Is it easier to separate milk from coffee, or milk from cereal? Explain.
There are many different ways to separate mixtures. List and describe as many as you can.
Time: 10 minutes

22. Activity One: Different Types of Mixtures
We will be looking at different types of mixtures (pg ), describing them and seeing if they separate with a filter.
Copy down this table in your notebook. Make a title for it No
