Find the variables in the following simple experiments and state which variable is the
independent variable, dependent variable, and the controlled variables.
1. Experiment to find out if tomato plants grow faster in full sunlight or partial sunlight.
2. Experiment to find out if red ants prefer honey over sugar as a source of food.
3. To find out if where fish survive better in rainwater or chlorinated water from faucet.
4. To find out if chicken grow faster if they are fed with pure corn or pure rice.
5. An experiment to find out if corn plants grow better in sand or clay soils

1. The dependent variable is the tomato plant because the tomato plants depends on the light to for the plant to grow. The independent variable is the light. The light does not depend on anything. In this experiment the variable that is being controlled is the light because the experimenter is controlling how much light the tomato plant is getting.

2. The dependent variable are the red ants because the red ants are going to determine(depend) to see if they like honey or sugar better. The independent variable are the honey and sugar because honey and sugar are a type of food and it does not depend on anything. The controlled variable is the food because the experimenter is controlling what the red ants like for food.

3. The dependent variable is the fish because the fish depends if they will survive in rainwater or chlorinated water. The independent variable is the rainwater and chlorinated water because the types of water does not depend on whether or not the fish survives. The controlled variable is the types of water (rainwater, chlorinated) because the experimenter is controlling the water that the fish will be exposed to.

I hope that this helps.
