Grade 8 Week 14: Waves and Tides

Last week we looked at the oceans features and currents.  Now we focus on other motions in the oceans.



What are waves?
How do they form?
What causes tides?
What is the difference between currents, waves, and tides?

Contract 14 gives you the choice to design your own contract to teach the class about waves or tides.

Grade 7 Week 13: The Respiratory System

This week we examine the respiratory system.

What are the functions of the respiratory system?
How do the structures of the respiratory system work together to perform these functions?

Science on Prezi

Contract 13 has you examine the respiratory system and it's diseases.

Grade 8 Week 13: Under the Sea.

After working on the Earth's waters in general, we now focus on the main point of this unit: the Ocean.

What features are found at the bottom of the ocean?
What affects the density of salt water?
What effects do different densities of water have on the ocean?


Contract 13 gives choices to diagram the oceans features, examine the effects of the ocean on weather and climate, or to focus on the El Niño
 event.

Grade 7 Week 12: Muscular System

A week ago, we began our Body Systems Unit.  We looked at how all the systems interact and then specifically the Skeletal system.  This week we get specific with the system that works closely with the skeletal system:  the Muscular System.

What are the functions of the muscular system?
What systems does the muscular system interact with to maintain homeostasis in the organism?

This week's Contract Week 12 has us look in depth at the funtion of the muscular system - when it's working correctly and when it is not.

Grade 8 Week 12: Water moves on Earth

After our look at the water cycle we will be examining other ways water moves around the Earth. From last Friday's presentations - what are some other parts of the water cycle that we learned? (like sublimation)

How does freshwater move on Earth?
How does it move due to gravity?
How does it move as ice?
How does it move underground?

Contract week 12 has you look at how we get our water in Plymouth, the Great Lakes, and the eutrophication of Lake Sheboygan(the marsh).

Grade 7 Week 11: Body Systems

We begin our own new unit on the Human Body.  We will be looking at one or two body systems each week for the next few weeks.  Important questions:

How do these systems work together to maintain homeostasis?
What is the function of the skeletal system?
What systems interact with the skeletal system to maintain homeostasis?

Contract Week 11 has you examine body systems in general or our first highlighted system, the Skeletal System.

Grade 8 Week 11: The Water Planet

This week we begin our next unit of Earth Science.  We start by looking at water.

What is the water cycle?
How does the water cycle affect us?
Why do belly flops hurt?
Why does ice float?
