Contact Forces
True or False
When two objects make contact, each object applies a force that is equal and opposite of the other objects force.
What is True?
This is the name of the process in which a liquid turns into a gas.
What is evaporation?
CO2, water, and sunlight.
What are the inputs for plants/producers?
The connection between our buying candy and orangutans in the wild.
What is palm oil?
This is the word for the smallest "unit" that makes up matter.
atom/molecule/particle
This force is due to interactions between surfaces as they rub against each other,
What is friction?
This is the variable that we change to see if it has an effect. What we purposely change in an invesitagtion/experiment.
What is independent variable?
The process in which producers uses energy from the sun to turn oxygen and water into glucose.
What is photosynthesis?
This is being greatly affected by the increase of oil palm plantations/farms.
What is orangutan habitats (or tropical rainforests)?
This is Ms Coffey's favorite color.
What is green?
This is the variable that is measured in any expeiment.
What is dependent variable?
Of the cups below, we would expect this one to warm up quicker when holding cold water:
Cup A: a single-walled plastic cup with a lid
Cup B: a single-walled plastic cup without a lid
What is B?
The molecules that make up our food.
What are proteins, fats, carbohydrates?
These organisms play an important role in recycling matter and energy in a food web. They use uneaten food, dead things, and waste for energy.
What are decomposers?
This is a property of a substance which means light is able to pass right through it. This is why a window is a terrible place to hide behind.
What is transparent
This is the force that is applied to objects moving through air.
What is air resistance?
This number tells us the average kinetic energy of a substance.
What is temperature?
Very small openings on the underside of leaves that allow gases to enter and exit.
What are stomata (stoma)?
A geographic area where all the living (biotic factors) and nonliving (abiotic factors) things interact.
What is an ecosystem?
The smallest unit that can live on its own and makes up all living things.
What is a cell?
This increases kinetic energy at a greater rate (mass or speed)
What is speed?
As the temperature of a liquid increases so does this.
What is kinetic energy?
Small structures inside cells that carry out cellular respiration to get energy to do things.
What are mitochondria?
People changing how land is used from one purpose to another?
What is land use change?
This is the variable that you want to keep constant in an experiment/investigation. The things you don't want to change
What is the controlled variable?
