Here is what I learned during our study of Structures and Mechanisms.

= Group 1's Bridge. =

This is our bridge. What i think we can change is make a triangle at the top of our bridge. Another thing I would change the bottom of the bridge because the bottom bent at 1 or 2 kg, I would change the bottom to two strips of paper. We came in 2nd last but it was worth it. Are group yelled "noooo" but we got 3 kg and we had fun bliding it. Are group had alot of FUN!

=Group 1's House.= This is are Awsome house. What I think we should change is the roof by making a smaller and cleaner roof. Another thing we should change is how big our house is we should make it smaller. We thougth ity was messy but we had a lot of fun making it. We bilt a flag and it says The Hypo Group. That is al i have to say about are awsome(but messy) house. =Group 1's Egg Portector.= This is are egg proter that has freckled fred in it. I think we could change the straws around the egg because the egg did not move but it would be better if the egg moved a little so the egg would not crack as easy. Even no we got 2nd last agian we had fun and it was the best thing that we bilt. Science Rules!

What happene is that the suger, salt and baking soda turned in to a brown and it ois still in its form how it started. The corn starch turned black from the iodine. So the suger, salt and baking soda is a pysicle change and the corn starch turned black so there is a cimacle change happening.

Are steel wool exparement. This is are steel wool exparement. It includes Steel wool, suger, salt, procside, water and somthing else. This exparement is pysicle because the steel wool did not change coulor.

media type="custom" key="21528710" This is what I researched in science. The Golf ball.

=EXTRACTION=

1. Golf balls are made of plastic and rubber.Plastic is made out Oil, Natural gas, and Petroleum. Rubber is made out latex from a para rubber tree. 2. The resources are from tropical areas from South America and in the Amazon (Brazil) but was spread by English farmers to the Far East.The oil comes from the ground which is took out by a oil pump. Now there's a video on how to make golf balls.This video will tell you how to make golf balls. It is minutes (5:01). [|how golf balls are made.] 3.The rubber is in a tree called a Para rubber tree. The rubber gets to a big Bucket as a sap. The oil, Natrial gas and the petroleum comes from the ground from a oil pump. 4. When we take out the oil and natural gas we are losing more and more of it. Also Animals are dying from oil spills. [|How to get oil] Now i am going to show you a video to get out oil. Did you know 3,902 animals officially have been collected dead from oil spills and 1,869 animals have been collected alive. Only 775 of those have been released into the wild. =**Production**= 5. This is a chemical change. The rubber get's into a round shape, then it get's a plastic outside is put around the rubber ball. So that is why this is a chemical change. 6. The extra rubber is recycled to be used again, and again. There is no smoke, no garbage to put in the dump. 7. There is NO consequences to the earth after the production. No smoke, No smog (in ponds lakes or oceans) No garbage to the dump. Just Recicing. =**DISTRIBUTION**= 8. The factory sends the golf balls to sports store, Walmart, everywhere. Then it gets to us. 9. There is a little bit of pollution in distribution.It comes from the trucks. So there is a little bit of pollution. =USE= 10. This product lasts at lest 100 sticks at 125 miles per hour. =**DISPOSA**L= 11.This product is disposed of by recycled or by getting thrown out. 12. This product can brake down. Golf Balls brake down in 100 to 1,000 years to naturally brake down to earth. 13.Some golf balls can be recycled and some can't. 14.There is a environmental consequence. The golf Balls is becoming a concern on this planet. 15.The product can be sustainable some what and some what not. The para rubber tree can get planted and planted again and again but the oil for the plasic cover will be gone in 100 or more years.

=Windmill.= This is a exparement I made with my group. The Windmill. I learned when we were bilding the windmill that if you turn the wheel that is called Kenitic energy. When you turn the wheel you are useing Kenitic energy, when it goes thourough the elasticthat turns the propeler at the end of a skuar.That is Kenitic energy. The types of energy that was used were Kentic, food, and the sun. The kenitic energy was from that's how I turned the propeler and the wheel. The kenetic energy from me is from the food. I ate the food so it gave me energy. The food got it's energy from from the Sun. The sun got it's energy from cemical energy. When we were bilding the Windmill we did not make or destory the energy we just transformened it. So now you know about diffrent types of energy from a homemade Windmill.
