Seventh Grade Week 10

We come to the end of our look into the diversity of living things by talking about the last two types of vertebrates: birds and mammals.

As with all things before this, we ask what adaptations do these organisms have to survive? How are birds and mammals adapted to living in many different environments?
More importantly, what trends do you see when you look back at all the living things we have talked about in this units. From bacteria to single-celled organisms to fungi and plants to invertebrate and vertebrate animals.

As with previous contracts, contract 10 has us look at a specific species and describe how it meets its needs for survival.

Eighth Grade Week 10

This week we finish our look at natural resources. Our goal was to look at some of the issues we face concerning our use of natural resources and to find some solutions.

Each class split into groups to look at a specific issue and research or create some solutions to that problem. Notebook projects

So, what are the issues we face because of our dependence on natural resources? What are we doing or what can we do to resolve those problems?

This week's contract 12 looks at our current use of resources and alternatives.

Tuesday, December 1, 2009

Seventh Grade Week 9

This week we move from invertebrates to vertebrate animals.

What is the difference?

Some of the things we focus on in general this week are fish, amphibians, and reptiles

How are fish adapted to live in water? What advantages do amphibians have over fish? How have reptiles evolved to life on land?

As with invertebrates, contract 9 focuses on a specific vertebrate species in the three phyla.

Eighth Grade Week 9

This week we begin our look at natural resources. We will focus on our own use of these resources.

How do we use natural resources? at home? at school? What is the good and the bad of this use?

This weeks contract looks at how we use resources in our home? How is your home heated? How do you conserve resources in your home? How do you recycle in your house?

This weeks contract is a combination of contracts 10 and 11.

Week Eight

Eighth Grade - A4.2-3: Geologic Time.

Last week, we learned that fossils give us a glimpse back in time. We also learned that thousands of fossils were found at the Rancho la Brea. That's one site! Millions of pounds of fossils covering only a few tens of thousands of years! The Earth is more than four and a half BILLION years old! In Social Studies you may cover 100 to 1000 years in a year at school. How do we take all that information and laid down over 4.5 billion years and learn about it in a week?

Answer this: How are these facts put in chronological order? How do we know that fossils are really that old? What can we learn from looking at the whole history of the Earth? What did Wisconsin look like in the various ages of the Earth? How did the changes to Wisconsin affect life in Wisconsin during those ages?

Contract 8 to be presented on Friday.



Seventh Grade - C4.3-4: From Clams to Insects.

This week we end our look at invertebrate animals animals. When we started, we thought all animals were generally the same. Hopefully, we are seeing there are some bizzare behaviors out there. Who knew that some animals try to save their lives by eviscerating themselves and regenerating. Weird stuff.

Answer this: What special adaptations do these animals have for survival? Compare and contrast each type of invertebrate we talk about to other invertebrates and to other animals in general.

Contract 8 asks you to again research a specific invertebrate from selected phyla.

Tuesday, November 3, 2009

Week Seven

Eighth Grade - A4.1: History set in stone.



We start our geologic time unit this week. As we look back at times when Wisconsin was a shallow sea, when giant carnivorous birds roamed the earth, or when mass extinctions occurred, we ask ourselves, "How do we know that?"

Answer this: What types of fossils are there? What can we learn from them? How do fossils form? What processes expose these long buried fossils?

Contract 7 to be presented on Friday.


Seventh Grade - C4.1-2: From Sponges to Jellyfish.

This week we start with the beginnings of multicellular animals.

Answer this: What do these animals look like? How are their bodies oranized? What invertebrates can we find in our aquarium?

From Frogger

This week will will be setting up our class terrarium/aquariums to learn the needs of living things.

We will also be collecting some water samples to make wet-mount slides to view living cells.

All of this and Contrat 27.

Wednesday, April 29, 2009

4.3 & 4.4: Acids, Bases, and Alloys

Our final chapter of the chemistry looks first at acids and bases.

How are they related?
What makes a solution an acid? What makes a base?

And then we focus on alloys.

Why are we talking about metals during a solutions chapter?
How did the copper penny turn "silver"? "gold"?

All of this culminates on firday with presentations for Contract 26.

Tuesday, April 21, 2009

4.1 & 4.2: Solutions

This week we begin the final chemistry section: Solutions. Solutions are a special type of mixture where two parts are combined to make a new product with its own unique properties.

How and why do the properties of the solution differ from those of the solvent and solute?
How can we change the solubility of the solute in the solvent?

Those are a few questions we ask in Contract 25.

Tuesday, April 14, 2009

3.3 & 3.4: Energy in Reactions

This week we finish our Chemical Reactions unit as we look at bond energy and real-life examples. Be able to...

Describe energy change in a chemical reaction.
Give examples of how living things use chemical reactions to create and store energy.

These are also our choices on Contract 24.

Wednesday, April 8, 2009

3.1 & 3.2: Chemical Reactions

This week we are discussing chemical reactions so that when we can eventually do a few reactions in a lab and know whats going on. So...

What is going on during a chemical reaction?

We also learn that because of the Law of Conservation of Mass, what goes in must come out. While molecules are rearranged, the type and number of atoms stay the same in a reaction. So...

Balance the following Equation:

NO + H2 -> NH3 + H2O

Have you found a reaction you want balanced in your Contract 23 research? Post it!

Wednesday, April 1, 2009

2.3 & 2.3: Chemical Bonds

We just finished up our "scavenger hunt" of chemical bonds today.

What items do you find around your house that we use because of their unique bond properties?

Contract 22 focuses on Covalent and Ionic bonding.

Wednesday, March 11, 2009

1.2 & 1.3: The Periodic Table of Elements

This week we wrap up atomic structure with the Periodic Table.

What are the different groups or families on the Periodic Table?
Why are those groups seperated in the ways they are?

Contract 20 will finish up our ceiling Periodic Table.

Monday, March 2, 2009

1.1: Atomic Structure

This week we begin our physical science unit with a look at the basic building materials of our universe: Elements.

A few questions:
What is the structure of an atom?
How does this structure influence the properties of the element?

...and your questions:
What are protons, neutrons, and electrons made of?
Can those subatomic particles change their shape?
How do we know that those particles are even there?
How do stars create elements?
Why do elements give off certain colors?
How do ions form?
Why do atoms combine with other atoms instead of staying as just one atom?
What keeps electrons from becoming attached to protons in the nucleus?

Challenge: Physicists try to describe our vast universe by studying the smallest parts of an atom in Quantum Physics. Try and explain the Quantum Theory. What is Quanta? Explain the String Theory.

We crossover with the unique element writing project for Language Arts. This week, show the structure of your element by building a model for Contract 19.

Wednesday, February 18, 2009

4.3: Oceans as a Natural Resource

What do we take from the oceans? How does it affect our daily lives? How does our use of these resources affect the world we live in? Those are a few of the questions we will ponder this week.

We will also be doing a lab activity after watching the Nature feature Crash: A Tale of Two Species.

See if you can find information on the sturgeon and the paddlefish, two other "living fossils" a bit closer to home.

This weeks Contract 18 looks at the cause and effect related to our use of natural resources found in the ocean.

Thursday, February 5, 2009

4.1 & 4.2: Ocean Environments

One of the main concepts that spans all the science we cover in eighth grade is that things change over time. For organisms, these changes are usually in response to the environment. In this chapter we take a look at many different ocean environments. We also study the organisms in each biome.

What are the different zones in the ocean?
How do these zones differ from each other?
What are some adaptations that organisms have to live in these different zones?

This weeks contract can be found at Contract 17.

Thursday, January 29, 2009

3.3 & 3.4: Waves and Tides

As we finish talking about water in motion we focus on waves and tides. The main question we will try to answer: causes?

We also do a few activities that look at how storms affect wave formation, how waves travel, and how tides can be used for energy production.

This week I will give you creative permission to design your own A contract in Contract 16. I look forward to seeing what you come up with.

Monday, January 19, 2009

3.1 & 3.2: Oceans are connected

The next few weeks will take us to the world's oceans. Chapter 3's big idea is that there is really only one ocean that is a connected system of water in motion. Why are there different oceans with different names in different parts of the world?

In what ways does water stay in motion?
What makes the water move in those ways?
What are the causes and effects of surface currents?
What are the causes and effects of deep currents?

You may recall in Unit A Chapter 1 we learned about the different movements of the Earth's crust and what those movements did to the surface. We can see what those effects are on land, but until the 1950s we thought the bottom of the ocean was flat. What does it really look like? What formations are there? How do we know?

Monday, January 12, 2009

1.2 & 1.3: Water Underground and on the Surface.

Last week's discussion on the water cycle focused mainly on water in the atmosphere. This week we look at water on the surface and underground.

Where do we find freshwater on the Earth's surface?
Why do we find it there?
How do these bodies of water form?
What is the water table?
How does water fill underground spaces?

This weeks Contract Week 14 focus on local bodies of water and how we get our water here in Plymouth?

Tuesday, January 6, 2009

1.1: The Water Cycle

We are done with Unit A! Does that mean we forget all we have learned? In our first unit we looked at how our rocky planet is moving, what that movement means, and how we affect this chunck of space rock that we are living on. In our new unit we will learn about our how our watery planet is moving, what that movement means, and how we affect this water world we are living on. Sound familiar. All of those concepts we scribbled on to the paper of our unit A exam come back to haunt us again. It's almost like these concepts are important and apply to many things...

This week we look at how water moves throughout Earth and its atmosphere.

Where do you see water?
How does water move throughout Earth's land, ocean, and atmosphere?
What causes this movement?
How are our daily lives affected by how water moves?

With this new unit we are going even more into the technology we have, so a few reminders.

1. Contracts can now be done online in lieu of class presentations on our class wiki. See me if you would like to take advantage of this starting with Science Contract for Week 13
2. Everyone is expected to post their thoughts on the weekly questions once per chapter(every two weeks).
3. There are now three participating groups signed up for the We Can Change the World Challenge. Get a group, sign up, and make a difference for an extra contract grade before March 9th.

Here are your Contract 13 Pics!
