Week4_Need for speed

I learned that for the Red Team they had a triycle to make it become much faster. For the Blue Team they had a wagon that is rode on four wheels. A triycle their are three wheels one in the back and two in the front. They put a electric screw driver and connect it to the wheel which they called a Direct Drive. For the wagon to go faster they placed a chain onto the wheel and connect a electric srew driver to the chain.

If I was to do the same activity the teams did I would did there soultion. I said that because both groups worked together and did team work. They also wrote all of there conclusions down before they begin there experiment. I also learned how team work will help get the job done. They most likely use the electric screw driver to complete their task.

Week4_Prompt#3

Many cold packs used for sports injuries are activated by bending the package causing the substance inside to chemically react because the hot heat is calming the person down. Like if you have a bump or something is sparn they usually put some cold ice on it. The reason is because the ice is a solid and the solid particles are together and doesn't move. The heat package is either a gas or a liquid. Heat is involed in this process because the heat brings down the pain so it wouldn't hurt so much.

Week1_Prompt#1

When you hit a nail into a board using a hammer,the headof the nail gets warm because energy from the hammer brings force to the nail. The nail can't help so the nail goes down into the object. All this happens bcause of the terms of kinetic energy and potiential energy. Also the head gets hit first because the head is the tip and you can't nothing else besides the tip. This what I think will happen from kinetic energy when the head gets hit by using a hmmer.

Week2_Prompt#

The reason a full pot of soup over flows because of the boiling point. It's because the hot heat in the pan is caused from the fire which brings the object up to the air. The heat keeps the object over flowing so that it's nothing in with the hot water. If you put a top over the pan you will see the condensation coming on the pan so that the pan will frog up. Also then if you lift the pan up off the hot substance all the heat will evaporate to the air so that the substance begins a melting point.

Week3_Prompt#2

When water evaporates it's because states of matter which are liquid, solid, and gas. It starts from a liquid to a solid to gas. When it's a liquid, the particles are moving all around in different ways. When it's a solid, the particles are frozen so that the particles cannot move around. When the liquid changes from a gas it's because of the boiling point. A liquid changing to a liquid is because of the melting point.
