Bell Ringer: Science/ DensityOn Page 1 of your notes:1. If you were trying to dig a hole to China, do you think you would be able to? Why or why not?2. Compare this apple slice to the interior of the Earth. How does each layer of the apple correspond to each layer of the Earth?
Today’s LEQ: Why is the inside of the Earth divided into layers?By the end of today, you should be able to…1. Define Density.2. Explain the difference between objects that are more dense and objects that are the least dense.3. Identify objects that are more dense and less dense in comparison to each other.
Experiment- Page 3 in your notes• Density Lab• Explore how density affects the layers of the Earth – Time management – Follow procedures – Clean up

Synthesize this Information…Turn to your partner and complete:• Density is _____• ______ dense materials sink• ______ dense materials float
Hypothesis• Page 2 in your notes- label it Density experiment• I predict that Earth’s inside separates into layers because: ________________________________ ________________________________
Gather Data• Draw and label what your graduated cylinder looks like. (Make sure you label each liquid)
Analyze Data• Why did the syrup sink to the bottom?• Why did the oil float on top?• Make an analogy comparing your density column to the layers of the earth. – Ex: The syrup is like the inner core because it is the most dense layer.
Write Time! What did we learn? • Draw a cross section of the inside of the earth and label each layer. • If you were trying to dig a hole to China, do you think you would be able to? Why or why not? • Why does Earth’s inside separate into layers? Why aren’t they all mixed up?
