Earth's 4 spheres (Earth's System)

Class, these are great videos on Earth's 4 spheres, or Earth's system as it's called sometimes. With some of you we saw them in class as well. Take a look again, its an excellent review for your Test:

Watch these videos and include a 4-5 sentence summary in your notebook of what you learned and what was interesting.

Planning an Investigation

Class, here is a link to a document on how to plan a scientific investigation. It goes over all the steps of the Scientific Method, please review it --> Planning an Investigation

Here are some notes from class that are important: 

A question is testable if it can be answered through investigations that involve experiments, observations, or surveys. You have to be able to observe or measure the collected data.

Effect and affect are 2 common words used when writing a Research Question.

•effect- the result of something (noun)

•affect- means to influence something (verb)

•Examples: What is the effect of drinking too much soda?                  How does working out affect your body?

Finally, here are good videos that go over the Scientific 
Method. This first video is excellent because it goes over the
steps of the Scientific Method and how the steps can be in a 
different order sometimes, depending on the experiment itself. 
Check it out and you'll see what I mean: 

This second video is a song that reviews the Scientific Method too:

Density Project

Science Project:
Density

As infants we learn to stack blocks, taking one block and placing it on top of the other, hoping that it will not topple. Just as we learned to build a tower of blocks we can learn to build a stack of liquids. Most liquids, when poured into the same container will mix. However, some liquids do not mix with others so instead they separate into layers. What happens if you drop a small amount of oil into a glass of water? The oil floats to the top. In this experiment we will create a liquid gradient based on density.

Problem:
In this experiment students will learn about density by creating a liquid gradient.

For more engaging science activities, go to Education.com!

Materials:
12 oz. glass (tall)
Water
Honey
Vegetable oil
Rubbing alcohol
Other household liquids
Food coloring (optional)
Measuring cup

Procedure
From you research create a chart of densities among various household liquids. Use the following: water, honey, vegetable oil, and rubbing alcohol. Find more liquids in your home but have an adult make sure it is safe to mix with other liquids.
Based on your chart what has the greatest density? List the liquids in order of decreasing density.
Now you will start building your layers. From your list (most dense to least dense) start pouring the liquids into the glass.
Measure ¼ cup of each liquid and carefully pour the liquid in the center of the glass. Do not pour the liquid down the sides of the glass.
Continue pouring the layers in the center of the glass. The liquids may mix while pouring. Wait a few minutes for the layers to separate before pouring the next layer.
You can add food coloring to the liquids to see the layers better.
