Resources for Lesson 12...

Making Sap into Syrup...

What happens when sap is boiled?

Analyze data to determine if sap is the same thing as syrup with water added back.

What about another sweetener?

Watch the video to figure out how corn syrup is made.  Record you notices and wonders in the chart.

Are there other sweeteners?

Read the sweetener you were assigned.  Discuss the answers to the following questions and record the answers in your science notebook.

1.  Is this a natural or synthetic food?

2. Where does it come from?

3. How is it made?

How do we identify if something is natural or synthetic?

Read Where else does our food come from?  Look for evidence to determine if you sweetener is natural or synthetic.

Investigate ingredients of packaged foods

Record the first two ingredients of the food label you were given.  Discuss with your group where the ingredients came from and whether they are natural or synthetic.

How is flour made?

Watch the video to figure out how flour is made.  Is it natural or synthetic?

Other Food Labels...

What's in food items we eat from animals?

Read Chicken and Cow Diets.  Discuss the following questions... 1) What does the animal eat? and 2) Categorize those foods.  Where do those foods come from?

What we figured out this lesson...

• Everything we eat contains matter that came from either plants or animals.

• Some foods we eat have been processed either physically or chemically, but we can still trace them back to originally coming from plants.

• Most animals, including humans, eat plants, other animals that once ate plants, or both.

• Most animals, including humans, use the food molecules they eat to build up larger molecules for growth, to get energy by burning glucose through cellular respiration, or to store for later use.
