Lesson 10

Lesson Objectives...

• Analyze and interpret data using graphical displays and statistics to identify temporal relationships to provide evidence for how M’Kenna’s pattern of body growth and weight have changed over time compared with typical children her age. 

• Obtain, evaluate, and communicate information to determine the central ideas in an article to help determine where fat (matter) goes when people lose weight. 

• Plan and carry out an investigation to produce data to serve as the basis for evidence to answer the question, Where does matter go when people lose weight?

Resources for Lesson 10...

Identify Patterns in M'Kenna's Weight

Observe M'Kenna's Height and Weight Chart.  What you see?  What do you think that means?

Conduct the Fat Burning Investigation

Use the instruction for the Fat Burning Investigation and videos to figure out what is happening when fat burns.

Burning the Wick Alone

Record observations from the video in your science notebook.

Burning the Vegetable Oil and a Wick

Record observations from the video in your science notebook.

Burning the Animal Fat and a Wick

Record observations from the video in your science notebook.

What we figured out this lesson...

• When a person / animal loses weight, fat seems to go away. Some say when you lose weight you "burn" fat.

• When we literally burn different types of fat, the mass seems to go down, just like when a person loses weight!

• The properties of the vegetable oil and duck fat change before and after they are burned.
