Hypothesis, Theory and laws

Hypothesis: (good guess)
1. I think the plant using the culligan water will grow better than the one with tap water.

2. I think that when you shake a soda that it makes them fizzy.

Scientific Theory: (has to be proven over and over again)
1. The earth is at the center of the universe.

2.Expanding Earth
Our modern understanding of the interior and behaviors of the Earth is strongly based around plate tectonics and the concept of subduction. But before this idea was widely accepted in the late 20th century, a good number of scientists subscribed to the much more fantastical theory that the Earth was forever increasing in volume. The expanding Earth hypothesis stated that phenomena like underwater mountain ranges and continental drift could be explained by the fact that the planet was gradually growing larger. As the globe’s size grew, proponents argued, the distances between continents would increase, as would the Earth’s crust, which would have explained the creation of new mountains. The theory has a long and storied past, beginning with Darwin, who briefly tinkered with it before casting it aside, and Nikola Tesla, who compared the process to that of the expansion of a dying star.

How it was Proven Wrong:

The expanding Earth hypothesis has never been proven wrong exactly, but it has been widely replaced with the much more sophisticated theory of plate tectonics. While the expanding Earth theory holds that all land masses were once connected, and that oceans and mountains were only created as a result of the planet’s growing volume, plate tectonics explains the same phenomena by way of plates in the lithosphere that move and converge beneath the Earth’s surface.

Law: (cannot be discovered)
1.law of gravity

2.Newtons law of motion

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.


III. For every action there is an equal and opposite reaction.

Mythbusters

Mythbusters Video

1. Name at least 3 of the myths used in the video - (for example, can a light bulb blow up a car)

Can you make a Bamboo Cannon with homemade gun powder and bamboo?,  Can you make an Ear Wax Candle? and Can you stick you hand in Multan led without getting burnt?

Multan led: Comfirmed

Bamboo cannon: Busted

Mail the Coconut: Confirmed

3. List what you thought was the best part of the video.

The part were you make an ear wax candle, the people were all throwing up and getting sick.

4. Do you think that Mythbusters is science? Explain why or why not.

Yes, I think they are scientist because the test the myths like there real scientist.

5. Which experiment do you think is most dangerous from the video?

When they stuck there hand in the Multan Led they could have burned there hands off.

6. Can you think of a myth or something that happened in a movie that you've seen that you think should be tried on mythbusters?

Does sugar make kids hyper active?
