Experiment Format
Title:
This should state the problem to be solved. For example, “Is it better to catch a ball with one or two hands?”
Problem or Question
This is 1-2 sentences that describes the problem or question you are trying
to solve. It can be in the form of a sentence or a question.
Hypothesis:
What do you think will happen? Often stated in “ if…then…”format. “If I catch using
both hands then I will successfully catch more balls than if I only use one hand”.
The variable mentioned after “If…” is the independent or manipulated variable
(two hands). The variable mentioned after the then is the dependent variable you will be measuring.
Materials:
o List all
o Materials needed
o To do
o Your experiment
Procedures:
1. This describes the process in chronological order and describes the controls
and variable to be measured (dependent variable) as well as the number of trials.
2. It should be written so that a person who doesn’t know anything about the experiment
Knows exactly what you did and exactly how you did it.
3. It should be written in numbered steps (1…2…3…,etc.) NOT in paragraph form
4. It should be as many numbered steps as you need, but not TOO long
Data/
observations
This is where you write the evidence and observations (in a paragraph) that you
noticed during your experiment, especially if you collect qualitative data.
All quantitative data also needs to be shown either in a table of data or in a graph, clearly titled and labeled.
THIS IS NOT WHERE YOU ANSWER WHAT THE DATA MEANS
Analysis:
Write a paragraph that explains what the Data/Observations mean here. You should also describe any mistakes you may have made during your experiment or anything that might make your data inaccurate.
Conclusions:
This is a paragraph answering the following:
• What was the purpose of the lab
• What was the hypothesis and was it proven or disproven
• What did you do (very briefly- one or two sentences)
• What was the outcome
• How could you improve this experiment or extend the experiment further.
