The Scientific Method
Jim wants to conduct an experiment to see if light will reflect off different materials. What does Jim have to do before starting his experiment?
What is write a hypothesis?
If I have a ball that is at a height of 3 meters and has a mass of 9 kg it has this much potential energy.
What is 264.6 J?
An apple is an example of this kind of energy.
What is chemical energy?
Thanksgiving is on this date this year.
What is November 27th?
A light bulb turns this electrical energy into this kind of energy.
What is radiant?
This is the comparison group in an experiment.
What is the control group?
I throw a frisbee with a velocity of 5 m/s and it has a mass of 1.7 kg, making it have this much kinetic energy.
What is 13.35 J?
This is the type of potential energy found in a compressed spring.
What is elastic energy?
These cartoon characters famously ate popcorn, buttered toast, pretzel sticks, jell beans, and an ice cream sundae for their Thanksgiving meal.
Who are The Peanuts? (Charlie Brown)
Your body uses this kind of energy from your food and turns it into motion and heat.
What is chemical?
Jasmine is doing an experiment to find out if plants grow better with rock music, country music, or no music. This is the independent variable in the experiment.
What is the type of music?
I throw a 1.7 kg frisbee and it has a total kinetic energy of 25 J, making it have a velocity of this?
What is 5.42 m/s?
This is the energy of motion.
What is kinetic energy?
This is the average cost of a Thanksgiving meal for 10 people.
What is about $50.
A windmill turns wind into this type of energy.
What is electrical?
Natalia conducted an experiment to learn more about the kinetic energy of a marble. She rolled a marble down a ramp to see how far it would move a cup at the bottom of the ramp. This might be a reason Natalia got a different result each time.
What is she started the marble at a different place, and/or pushed the marble a different amount, and/or placed the cup in a slightly different place?
A potted plant has a mass of 10 kg and has a total potential energy of 55 J, this means that it is on a ledge this far from the ground.
What is 0.56 m?
This man was president when Thanksgiving became a National Holiday.
Who was Abraham Lincoln?
A toaster turns this kind of energy into this kind of energy.
What is electrical energy into thermal energy?
These two words should always be a part of your hypothesis.
What are "if" and "then"?
I have a computer that is on a ledge that is 10 m of the ground with a mass of 5 kg. It has a kinetic energy of 10 J. This is the total MECHANICAL energy of the computer
What is 500 J?
This is stored energy.
What is potential energy?
The Thanksgiving Day parade in New York City is named after this department store.
What is Macy's?
This kind of energy is given off in every energy transfer.
What is thermal energy?
