This is the definition of energy.
What is "The ability to make things move or change"?
100
This is the definition of equilibrium!
What is "a balanced state in which a system is stable, such as when two or more samples are at the same temperature"?
100
This is the definition of thermal energy!
What is "the total kinetic energy of all the molecules that make up a sample or system"?
100
Protein molecules travel through this system of the body to be broken down into amino acids.
What is the digestive system.

This is the number of units our class will have completed by the time we are done with our unit test tomorrow.
What is "4"?
200
True or false: When a sample touches something cold it gains more cold energy. When a sample touches something hot it gains more hot energy.
What is false?
Bonus explanation: Energy is transferred from hotter objects to colder objects. There is no such as "cold energy" being cold is the absence of thermal energy.
200
True or False: These samples are touching so they are at equilibrium.
What is "these samples are not at equilibrium"?
Bonus: but they will be eventually
200
After they have been touching for a while, which of the two top plastic pieces will be cooler, and why?
The larger top plastic piece will be cooler than the smaller top plastic piece, because the energy that transferred to it was spread out over more molecules.
200
This is what all living things are made up of.
What is a cell?

Mr. Harman has a sticker of this insect on the water bottle he keeps in the classroom.
What is a "Praying Mantis"?
300
A warm bottle of soda is put into a bucket of ice. Draw a simple model that shows show energy moves in that system.
What is:
(Answers may vary)
300
This is what will the ending temperatures of both boxes be when they reach equilibrium. (Draw a picture)
What is:
300
Which sample is hotter?
Bigger box: 2
Smaller box: 4
300
This is the term that describes the gene version that instructs a cell to build multiple different kinds of protein molecules.
What is "heterozygous gene versions"?
300
This is the number of LiveSchool points a student loses for eating during class.
What is "5"?

Rewrite the second sentence to be more accurate:
If you have a fever putting a cool damp cloth on your forehead can fix the problem. This is because the cold object/cloth destroys energy from the hot object/forehead.
If you have a fever putting a cool damp cloth on your forehead can fix the problem. This is because energy transfers from the hot object (the forehead) to the cold object (the cloth).
400
As the knee gets colder from the ice pack, this is what happens to the kinetic energy of the molecules of the ice pack.
What is "The molecules in the ice pack have more kinetic energy transferred into them"?
400
Revise the statement to make it true:
Molecules combine together to get hotter or colder.
Molecules collide into one another to transfer energy from one molecule to another. (answer may vary)
400
A baby duck have 75% of it's mothers traits and 25% of it's traits from it's father. This is the % amount genetic material the duck inherited from it's father.
What is 50%?
400
This is the name of the yellow sac spider we used to learn about traits and features in the last unit.
Who is "Bubbles"?
500
When two molecules collide, this is what happens. (Answer must include all necessary vocab)
What is "The molecules transfer energy to one another"?
500
This is what the average kinetic energy of both pans (in kJ) will be eventually, after being placed on one another.
What is 50kJ?
500
This is the total thermal energy in the system (in kJ) and the temperature of the system (in degrees Celsius)
What is 255 kJ of energy and 55.7 degrees Celsius)
500
If an athlete were to drink a simple syrup made entirely of glucose molecules, it would increase their ability to exercise because their cells would be able to perform this function.
