Unit 1: Movie Special Effects

Essential Questions

How can chemical concepts be used to produce special effects for a movie?

How can conclusions be drawn from data and evidence that is collected?

How are measurements made?

How are significant figures used?

What is matter, and how can it be classified?

Chapter Challenge Overview

Work with a partner to create a story line and produce special effects based on the chemistry you learn

Demonstrate the special effects you create

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

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

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

Activity One: Video

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

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

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

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

Starter

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

Activity One: The Heating Curve for

Water We will investigate how the temperature changes

when ice melts (pg. 634-635)

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

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.

Activity One (cont’d)

Due Date: August 28

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

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

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

Activity One: Different Types of

Mixtures We will be looking at different types of mixtures

(pg. 644-645), describing them and seeing if they separate with a filter.

Copy down this table in your notebook. Make a title for it

No Materials mixed with water

Activity One (Cont’d)

Follow steps 1-4, completing your data table as you go.

What other materials will you need to get from the lab bench?

Instead of a laser, use a flashlight

Time: 50 minutes

Activity Two: Interpreting Results Get together with 2 or 3 other people who

were not in your investigation group

Share your findings with each other, and discuss any discrepancies

Time: 15 minutes

Closing Activity

Classify the following as a suspension, colloid, or solution. Explain Orange juice (with pulp), apple juice, hot

coffee, milk, olive oil

How could you separate the following? Sugar dissolved in water
