You can make a maze for the branch or branches of the potato to grow out of the box.
Put your potato in a shoebox at the very end with some fertilizer, and a hole at the other end. Then put obstacles in the box, so your potato branch can make its way through the hole. You can also identify something that has starch. To find out if that thing contains starch, you have to put iodine on it, and see if the thing changes into a blue to purpleish colour.

What is an independemt variable?
An independent variable is the variable in the experiment that affects the other variable. For example, in an experiment that tests the affect of the amount of fertilizer on plant growth, the amount of fertilizer is the independent variable and the plant growth is the dependent variable. This is because the plant growth DEPENDS on the amount of fertilizer.
What is a control of a science experiment?
For instance, if you wanted to experiment on plant a, plant b, and plant c. You would put plant c to one side, treat it like a normal plant (water, feed, etc.) and call that the control. You could then experiment on plant a and plant b - feeding them differing fertilisers, allowing pests to attack the plants, and so on. At the end of the experiment, you could compare the growth of plant a and plant b to the control plant c. Though plants are mentioned above, the principle relates to any experiment - you need a control to compare against the end results of the experiment.
Examples of independent and dependent variables in science?
Independent and dependent variables are the variables that change during the course of an experiment. An example might be an experiment on how temperature affects plant growth. Changing the temperature is the independent variable, while the level of plant growth that results is the dependent variable.

Why is it so important to control variables in an experiment?
You need to control variables in an experiment so as to make sure that only the variable you are testing and changing is the one affecting the results of your experiment. For example, in an experiment to find the effect of light intensity on the rate of photosynthesis of plant, you'll change light by putting a plant in sun and another in dark but you must not change carbon dioxide level for both plants so by that you have controlled other variables in the experiment(variables which must be the same always in the experiment).
What is a controlled experirment?
A controlled experiment is an experiment in which all factors are controlled except for the one variable you will be altering. If you were performing a controlled experiment on the effects of fertilizer on plant growth, for example, you have to control plant variety, exposure to sunlight, soil type and water ration. The only thing you would change is the fertilizer used on each plant.
What is an experiment which only one variable is changed?
An example of an experiment where only one variable is changed is testing the effect of different amounts of sunlight on plant growth. In this experiment, all other factors such as soil quality, water, and temperature are kept constant, while the amount of sunlight received by each plant is varied. This allows researchers to isolate the specific impact of sunlight exposure on plant growth.
What is an independemt variable?
An independent variable is the variable in the experiment that affects the other variable. For example, in an experiment that tests the affect of the amount of fertilizer on plant growth, the amount of fertilizer is the independent variable and the plant growth is the dependent variable. This is because the plant growth DEPENDS on the amount of fertilizer.
What is the dependent variable in a science experiment?
The dependent variable is the effect of an independent variable. For example, if a science experiment is done with plant growth under a certain amount of light, the height of the plant is the dependent variable because it depends on the amount of light.

Though plants are mentioned above, the principle relates to any experiment - you need a control to compare against the end results of the experiment.
What is a good plant experiment?
A good plant experiment is the study of sunlight on a plant. Place one plant in sunlight and one in the shade and watch the changes between the two.
How do you write hypothesis?
You write an if-then statement to represent what you think will happen at the end of your experiment. For example, let's say someone did an experiment on if chemicals effect plant growth. The hypothesis would be, "If chemicals contain unnatural substances that are un-earth friendly, then they will effect plant growth."
What is an example of method?

What is a good plant to experiment with?
Cannabis
What is an example of a binomial experiment?
A binomial experiment is a experiment that consists of repeated trails, with two possible outcomes. An example of this would be a coin toss.Ê
