Wind Erosion

May14

unnamed-2

In science class we made models of different erosions. My group had wind erosion. We first had to look up what happening during wind erosion and look for at least seven different words that we different know before to use as vocabulary. Our seven words are ventifacts, loess, abrasion, via, creep, saltation, and suspension. Ventifacts are rocks that are formed in different shapes because of wind erosion. Loess are cliffs with jagged edges of rock that can be different sizes and it is formed be wind erosion. Abrasion is  the wind blowing through rock making it erode and grow smaller. Via is sand that has been moved by the wind and placed somewhere else and gets uplifted. Creep is big rock particles that are moved along the ground because of the wind. Saltation smaller pieces of rocks or pebbles that are moved or bounced along the ground because of the wind. Suspension is when very small rocks or pebbles get blown up into the wind and are taken somewhere else in the air. Once we got all of our words, we made a model of wind erosion in the desert. The picture above is our model. In the models we had to have mountains or hills, river or stream, valley or coastline. The model on the right is our before wind erosion and the model on the left is after wind erosion. After making our models each group presented their model of erosion and explained their seven vocabulary words.

Science Volcano

In science class we made groups and each group got to make a volcano. My group and I decided to make a shield volcano, after the Mana Loa Volcano. We made our volcano out of homemade play-dough, pant, a plastic cup, a bottle cap, and used tape to label different parts of our volcano. We labeled the side vent, the main vent, the crater, the pyroclastic flow, aa lava, pahoehoe lava, the pipe, the magma chamber, the magma, the hot spring, and the lava flow.

 

Spaghetti Towers

Dec15

In science we built spaghetti towers made out of spaghetti, marshmallows, and masking tape. We had to first do research about towers that can survive an earthquake. After we did research we designed a tower. Once our design was complete we had to buy supplies and start making a tower. We had the choose in buying insurance. My group brought insurance. On the day we started to build our tower, it fell over. We made a tower from the supplies we had, without insurance.

Math, How Can We Use It In Real Life

Nov21

A lesson that I learned in math is , 3-5. 3-5 is about finding the square roots of a number. Some examples of perfect squares are 1, 4, 9, 16, and 49. Their square roots are 1, 2, 3, 4, and 7. You can use square roots in real life, to figure out the length of a square. If you were building something and the area is 36, the lengths of the square has to be 6×6. You can use it for picture frames too. If you have a picture that has the area of 16, you will need a 4×4 picture frame. You can use square roots to figure out the length of something, if you know what the area is. You can use square roots when you are drawing a picture. If you picture has to be a certain length, but you know the area, you can buy the right length by finding the square root. Square roots are an easy way to find a length of a square.

Math Word Problem

Nov3

3-8 word problem and answer:

Noah and Jenna are taking a walk, and they both start at the same point. Noah walks 60 feet north, but Jenna walks 77 feet east. How far apart are Noah and Jenna?

In order to solve the problem you need to use a^2+b^2=c^2. You would have to use 60 for a and 77 for b. Then the problem would be 60^2+77^2=c^2. Next you would have to times 60 by 60 and 77 by 77, because you have to simplify the powers. You problem would be 3600+5929+c^2. You have to add 3600 and 5929. Your problem should look like 9529=c^2. Then you need to find the square root of 9529 in order to find the distance between Noah and Jenna. The square root of 9529 is 97.6. The distance between Noah and Jenna is about 97.6 feet.
