We learned alot about earthquakes.There are two types of earthquake waves, they each have their own features. The first waves are the fastest, or Primary waves. These waves of energy compact and expand the earth. They can also move through water.
Then there are the slower waves: Secondary waves. These shake the earth back and forth. but these waves won't go through water. they just dissapear, They need those links solids have to transfer their energy.

in our last experiment we got to play with mud and water. We set up a stream table with some dirt and elevated it with 3 text books on one side, then we poured water (out I think it was 24 oz). We then recorded the width at the middle of the channel the water made. The erosion was really interesting.

all energy in an extended way comes from the sun. this is the heat energy example. The sun creates energy that it RADIATES to the earth which gives life to organisms and they can use tools to create CONDUCTION transfers like a pot to the handle and there is also CONVECTION transfers that occur when liquids transfer heat to each other.

In class we did a lab to see what would happen if we mixed vinegar and baking soda. My team changed the amount of baking soda by 1 cm. each time. The amount of vinegar stayed the same at 20 ml. We measured it by putting a balloon over the beker we mixed it in and the carbon dioxcide blew the balloon up and we measured the size of the ballon in cm.
1cm baking soda = 22cm
2cm baking soda = 29cm
3cm baking soda = 32cm
4cm baking soda = 34cm
the more the baking soda the biger the biger the rection

what we did was we counted cars in our parking lot a few days before earth day so we could find out haw many people drive to school on a normal day and then we counted on earth day so we could find out how many people drove to school on earth day and could figure out how much carbon emmissions were saved.
