I want to prove that guppies (orange) are prettier than bettas (blue) using science.
It can't be done. Science can't answer opinion questions.
Easy. Just have people vote for the prettiest.
They are both equally pretty.
Orange animals are rarer, so the orange fish is the prettiest.
Which is NOT true about a good hypothesis?

I decided to see if feeding my fish dead insects would speed up their growth. I had 20 guppies so I put 10 in one aquarium and 10 in the other. One tank was fed the normal fish food. The other tank got the dead insects. What are the fish that got the dead insects?
Experimental group
Control group
Data
Dependent variables
I decided to see if feeding my fish dead insects would speed up their growth. I had 20 guppies so I put 10 in one aquarium and 10 in the other. One tank was fed the normal fish food. The other tank got the dead insects. If I am testing the dead insect food, why did I make an aquarium that got the normal fish food?
The fish that got the normal food are the experimental group.
The experimental group (insects) is compared to the control group (old food) so we can see if the independent variable worked.
I had 20 fish. That's too many for one experiment.
The normal fish food aquarium is the dependent variable. You must have a dependent variable.
My hypothesis is, "If I exercise every day then I will lose weight." I exercised every day for 6 months and I lost 18 pounds. Choose all that are true.
This hypothesis is written correctly.
The hypothesis is supported.
This proves that everyone that exercises every day will lose weight.
My weight is the dependent variable.
One of my fish has a white fuzzy patch growing on his side. I looked in my fish books, and I think it is a fungus. I put some medicine in the water, and one week later he was fine and the fungus was gone.
What was my hypothesis?
The fish is sick with a fungus.
If I give my fish the medicine then the fungus will go away.
My hypothesis was supported.
Fish sometimes get white fuzzy fungus growing on them.
One of my fish has a white fuzzy patch growing on his side. I looked in my fish books, and I think it is a fungus. I put some medicine in the water, and one week later he was fine and the fungus was gone.
What was the independent variable?
The fish is sick with a fungus.
The fish survived.
The medicine.
Fish sometimes get white fuzzy fungus growing on them.
One of my fish has a white fuzzy patch growing on his side. I looked in my fish books, and I think it is a fungus. I put some medicine in the water, and one week later he was fine and the fungus was gone.
What was the dependent variable?
The fish is sick with a fungus.
The fish survived.
The medicine.
Fish sometimes get white fuzzy fungus growing on them.
One of my fish has a white fuzzy patch growing on his side. I looked in my fish books, and I think it is a fungus. I put some medicine in the water, and one week later he was fine and the fungus was gone. My hypothesis was, If I give my fish the medicine for fungus then he will survive.
What should my conclusion be?
My hypothesis was supported.
The fish survived.
The medicine works against this kind of fungus.
If I put a little medicine in once every week then fish will never get the fungus in the first place.
What do we call it when we let other people try our experiment to see if they get the same results we did?
Peer review.
Research.
Publishing.
Fact checking.
In our plant experiment, which of these should be a constant?
The type of soil.
The amount of soil.
The amount of liquid given.
The size and type of cup.
All of these should be constants.
My dog keeps scratching at the door to go outside at night when I'm sleeping. To prevent this I did an experiment. I stopped giving her water after 6:00 in the evening. I took her for a walk right before bed. I played with her to get her very tired right after our walk, and I played soothing music while we were sleeping. It worked! She slept through the night. What is wrong with this experiment.
There are too many dependent variables.
There aren't enough dependent variables.
I didn't analyze the data.
There are too many independent variables.
Nothing is wrong. It worked, so it's good.
