Constants are

the group that you compare to

what you measure at the end

things that stay the same between groups in an experiment

things that change in an experiment

do an experiment

nothing else

make a conclusion

gather information

What would be the CONTROL group ?

plants with regular light

both plants

plants with red light

the amount of soil, time, and water for the plants

Which hypothesis is written correctly?

If I put a plant under red light, then it will grow faster.

If a plant is under a red light will it grow better?

Will a plant under red light grow faster?

I think plants will grow faster under a red light.

All are true about a hypothesis EXCEPT which one

It is written as an IF…. THEN

It’s an educated guess

It is in the form of a question. EX: Does....?

It’s the 3rd step in the scientific method

Which BEST describes why you want to have only one variable or thing different between two groups:

you don't need to have only one variable, you can change many things

to know exactly what caused the results

to make your data table easier

so the experiment goes faster
