What is a hypothesis?
Type of relationship between a bird and a worm is this.
What is predator/prey?
Type of cell that has chloroplasts.
What is a plant cell?
The reason for wearing seatbelts is our inertia. This law of motion describes it.
What is Newton's 1st law of motion?
A see saw at the playground is an example of this type of simple machine.
What is a lever?
The reason for doing multiple trials in an experiment.
What is to get more accurate results?
An organism that eats both plants and animals.
What is an omnivore?
Part of the cell that regulates what goes in and out of the cell.
What is the cell membrane?
The tissue box sits still on the table. This is the net force acting on it.
What is zero newtons?
The highest point of a roller coaster has a large amount of this type of energy.
What is potential?
The part of the experiment that is being measured.
What is the dependent (responding) variable?
A bee and a flower is an example of THIS type of symbiosis.
What is mutualism?
Part of the cell that makes energy from the food we eat.
Two kids pull on a tug of war rope with 3N & 4N of force to the right. One big kid pull on the rope with 8N of force to the left. The net force is THIS? (direction & force)
What is 1 N of force to the left?
A person who walks for 2 hours at an average speed of 4 miles per hour will go this far.
What is 8 miles?
All the things that need to remain the SAME during an experiment for it to be "fair" or accurate.
What are the controlled variables or constants?
The reason for populations to reach their carrying capacity
What is limited/limiting resources?
Organelle where photosynthesis takes place.
What is the chloroplast?
Having tread on the tires of a car provides this type of force to help reduce slipping.
What is friction?
A change in speed or direction.
What is acceleration?
A person wants to test the effects of fertilizers on plant growth. The dependent variable in the experiment is this.
What is the height/growth of the plants?
Deforestation directly impact this type of gas in the atmosphere that leads to climate change & global warming.
What is carbon dioxide?
Feature of a plant cell besides chloroplast that animal cells do not have.
What is the cell wall?
A 20 kg cart is pushed with 100N of force. It will have this amount of acceleration.
What is 5 m/s2?
A change in genetic material that leads to variation in a species.
What is mutation?
