Experiemnt with and explain how Newton's Laws of Motion apply to the physical world.
Experiment with and explain how friction and gravity apply to Newton's Laws of Motion.
Experiment with and explain the relationship between speed and acceleration.
Experiment with and explain how simple machines utilize mechanical advantage to transfer energy (potetial energy. kinetic energy, and various other energies).
Effectively explain how alternate forms of energy can be utilized to influence the United States energy needs.
Proficiency 1
Hypothesis- I think that the mass of the car will affect the distance a block of wood travels.
Materials -
-A hot wheels car
-6 pennies
-tape
-block of wood
-measuring stick (to see how far the block of wood goes)
-paper and pencil to record data
Procedure -
1- Gather all materials
2- First take the block of wood and places it on a flat surface
3- Roll the hot wheels car into the block and measure how far the block went. And record
4- Tape 3 pennies to the top of the hot wheels car and now roll the car at the block. And record
5- Add 3 more pennies to the car and roll it to the block. And record
6- Repeat steps 2-5 three more times
7- Graph
8- Clean up
Variables-
Cv- same car, same pennies, block of wood, surface you do it on
Iv-how many pennies you use
Dv- impact of block
Control- car
Proficiency 2
Hypothesis- Yes, because if the surface is rougher it will slow down the marble and if the marble is on a smoother surface then it will slide down fast
Materials -
1. 2 different kinds of paper
2. Ramp
3. Marble
4. Tape
5. Timer
6. Paper and pencil
Procedure -
1. Gather materials
2. First tape one off the pieces of paper on the ramp
3. Take ramp and tape it to a surface
4. Get your timer ready and roll the marble down the ramp
5. Record how long it took to get to the end of the ramp
6. Repeat 1-6 for the do next piece of paper
7. Now record all data
8. Graph
9. Clean up
Variable -
Cv-ramp, marble, surface
Iv- paper
Dv- marble speed
Control- ramp
Proficiency 3
3rd
Hypothesis- Yes, because the friction of wheels on the ground will slow the car down.
Materials -
1. Car
2. A ground surface
3. A hand to push
4. Timer to see how long it takes
Procedure -
1. Gather materials
2. Grab your car and roll it and time how long it goes for
3. Record 3 more times
Variable -
CV - car, surface, same person
IV- surface
DV- deceleration
Control - surface
