What is a Hypothesis.

200

I am a group that is needed so you know if your experimental variable had an effect. You compare your results of your experimental group to me.

What is the control group

300

I am the way you improve your experiement

What is repeat it several times?

400

Without me, you won't know if your results are due to the change you made to your IV, or just some other factor. You need at least 3 - 5 for an experiment to be valid. I stay the same for all groups

What is a constant

500

True or False and Explain

when your hypothesis is not supported, you can just change it to suit the results of your experiment.

What is False; you should to repeat the experiment and/or create new research questions to follow up with

What is a plant cell

200

I can carry out photosynthesis and respiration

What is a plant cell

300

What is a mitochondria

400

I control the movement of substances into and out of the cell based on size and concentration

What is the cell membrane

500

I am the movement of substances across a membrane without energy.

What is diffusion or passive transport

100

I control the entry of oxygen and the exit of carbon dioxide from your body

What is the respiratory system
