A partner and I had to create a project about Wind Erosion.

1. This project is an example of when the wind blows and wears away large rocks.

2. The second project shows that different types of dunes are shaped depending on how the wind blows.

3. This project shows that over time the wind wears away  the ground and removes the surface particles. It makes the ground lower than before.

4. The last example is of rocks that get hit with large particles in the wind which cause them to become dented. These are called ventifacts.

Volcano Project

For science we had to make a volcano out of a play dough like substance. We had to label 10 things and we painted it. When we put the clay around the bottle, it kept slipping off, so we had to keep putting more on. Sometime this week we will put ketchup, baking soda, and vinegar in the bottle and it will explode out of the top and out of some straws that are side vents. The ketchup makes it red, which will make it look like lava. It did not work as well as I would’ve liked, but it turned out okay.

Science Tower Project

Our class was split into groups and we had to create a tower out of spaghetti, mini marshmallows, and tape to hold an egg, at 40 cm tall, will remaining sturdy on an small earthquake simulator for 10 seconds. This is our tower on the second day of building. Photo on 12-12-14 at 1.35 PMOver the weekend our tower collapsed. Then someone in our group smashed it, so we had to do a little remodeling. Here it is after the third day of building. Photo on 12-15-14 at 1.51 PM #2We had a lot of extra small pieces that we could not use. We had to microwave the marshmallows to get them to be sticky again. It is definitely not 40 cm tall now, and we do not think we will be able to fix it. The grade is not all on how well the tower turns out, but our tower has no way to hold the egg, which is a problem. I hope our group will be able to fix it at least a bit more, so that we might be able to hold the egg without it cracking.

Math Word Problem-Pythagorean Theorem

If a helicopter flies north 12 miles, then turns east and flies 6 miles, how many miles would it be to fly back to it’s starting point? The shape is a triangle.

So for this question, the equation would be 12Screen Shot 2014-11-03 at 8.56.05 AM+ 6Screen Shot 2014-11-03 at 8.56.05 AM= cScreen Shot 2014-11-03 at 8.56.05 AM

12 squared is 144 and 6 squared is 36.

So the updated equation would be: 144+36= cScreen Shot 2014-11-03 at 8.56.05 AM

When you add the two together it is 180. So now, you have to find the square root of 180.

180=cScreen Shot 2014-11-03 at 8.56.05 AM

The closest you can get to the answer would be:

13.42

…because 13.42 x 13.42= 180.0964

 

Math 1-1, Rational Numbers

In the first lesson, I learned about how to simplify fractions and turn them into decimals. To turn a fraction into a decimal, you have to divide the top number by the bottom number and then you have the answer. You can either do long division or on a calculator. To simplify a fraction you have to divide the numerator and the denominator by the same number, and if you can’t, then it is as simplified as it can be, and if you can, you keep dividing it until you have the lowest it can get. urlurl-1
