Problem:Can we drop cookies off a table in to milk using simple machines and dominoes
Hypothesis:We can use a rube Goldberg to make cookies fall in milk.
Materials: Wheel and axle, dominoes, pulley, milk, 2 cookies, incline plane.
Variables:
cv: Person pulling the lever
iv: placing of the simple machines
dv: making cookies fall in milk.
Simple machines:
- Incline plane
- Screw
- Pulley
- Wedge
- Lever
- Wheel and axle
Proficiency 1 If newtons laws of motion did not able to the physical world than if you throw a baseball it would never stop. It would stay at the same speed until a bat hit it then it would go in the other direction. It would stay at same speed of the hit forever. The ball would also have to friction to stop or slow it down.
Proficiency 2: When you roll a marble on a flat surface it shows friction slowing it down until it stops. Friction and gravity apply to the laws of motion Because until I move the wedge then gravity makes the ball start rolling down incline plane on my Rube Goldberg. Then they are moving until a friction and objects make it stop.
Proficiency 3 In my Rube Goldberg it makes cookies fall in to milk after a series of simple machines.
Proficiency 4 Tommy will Pull back a hammer the hammer is a attached to a string so that when the string is pulled it lifts up a wedge. the wedge is standing because of screws holding it in place. the wedge is pulled up it release a toy car the car is the wheel and axle. The wheel and axle hits the domino's the domino's hit one domino that is attached to a string. The other end of the string has a domino with another domino on top of it. When it moves the domino on top hit another set of domino's which hit the two cookies in to milk.

Geothermal Energy is a great source of energy. Geo means earth and thermal mean heat in It is extremely power full and can be used to power multiply cities depending on the size of the factory is how much power it has. Geothermal thermal -dual flash and geothermal-thermal-binary cost less than advance nuclear, wind, hydro- small scale, solar-concentrating (most expansive). Geothermal is natural like hydro, wind, and solar. Geothermal is cheap and powerful.
