Biology
What does the cell wall do?
Protect the inner part of the cell & hold the shape
What happens when you add an acid to a base
Neutralization
What is buoyancy?
An object's ability to float in air or water
What are producers and what are consumers?
Producers can make their own food and energy, but consumers have to eat to gain energy.
What is a litmus test?
A way to detect the pH of a substance.
What part of the plant cell holds the "garbage"
Vacuole
Name the states of matter
What is surface tension?
A property of liquids that makes the surface behave like a stretched elastic sheet
Where does the energy in food chains come from? (Hint: think what plants need to grow)
The sun
What is the difference between control and experimental groups?
Control groups are your baseline, they provide a reference for your experiment and something to compare to. In experimental groups, you change one variable while holding all else constant.
Describe the process of photosynthesis
Water + Sunlight + Carbon Dioxide --> Oxygen and Sugars

What is density?
A measure of the amount of mass per unit volume of a substance
Describe the plant cycle
Seed > seedling germination > adult plant > pollination > fruit with seeds
Describe the Scientific Method

What is the role of decomposers?
They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
What is a non-newtonian fluid?
A non-newtonian fluid or suspension is a substance that does not follow the matter rules we talked about earlier! It can be a solid and a liquid depending on how much force we apply to it
