By definition, an experiment is a procedure that tests a hypothesis. A hypothesis, in turn, is a prediction of cause and effect or the predicted outcome of changing one factor of a situation. Both the hypothesis and experiment are components of the scientific method. The steps of the scientific method are: 1. Make observations. 2. Ask a question or...
The two key parts of an experiment are the independent and dependent variables. The independent variable is the one factor that you control or change in an experiment. The dependent variable is the factor that you measure that responds to the independent variable. An experiment often includes other types of variables, but at its heart, it’s all abo...
Fertilizer and Plant Size
For example, you think a certain fertilizer helps plants grow better. You’ve watched your plants grow and they seem to do better when they have the fertilizer compared to when they don’t. But, observations are only the beginning of science. So, you state a hypothesis: Adding fertilizer increases plant size. Note, you could have stated the hypothesis in different ways. Maybe you think the fertilizer increases plant mass or fruit production, for example. However you state the hypothesis, it inc...
Salt and Cookies
You don’t need a lab for an experiment. For example, consider a baking experiment. Let’s say you like the flavor of salt in your cookies, but you’re pretty sure the batch you made using extra salt fell a bit flat. If you double the amount of salt in a recipe, will it affect their size? Here, the independent variable is the amount of salt in the recipe and the dependent variable is cookie size. Test this hypothesis with an experiment. Bake cookies using the normal recipe (your control group) a...
Based on the examples of experiments, you should see what is notan experiment: 1. Making observations does not constitute an experiment. Initial observations often lead to an experiment, but are not a substitute for one. 2. Making a model is not an experiment. 3. Neither is making a poster. 4. Just trying something to see what happens is not an exp...
There are three main types of experiments: controlled experiments, natural experiments, and field experiments, 1. Controlled experiment: A controlled experiment compares two groups of samples that differ only in independent variable. For example, a drug trial compares the effect of a group taking a placebo(control group) against those getting the d...
