Scientific Method Lab: Sea Monkeys
Introduction:
We will be growing sea monkey cysts in the ideal conditions for hatching.
1. What is the problem in this experiment? Write this as a question!
Research:
In “the real world,” scientists do not just simply experiment when the thought crosses their mind; they
research the topic first. Before you begin this lab, research the questions below to learn a little about sea
monkeys. Keep this information, because you will be using it as part of your formal lab report.

Set up the experiment:
3. What is the independent variable?
4. What is the dependent variable?
5. List any important constants (aim for 5).
Procedure:
Write your own procedure. Be sure that it is given in numbered steps that can be clearly followed by another
scientist trying to replicate you experiment. Be sure that the variables and constants are accounted for. Keep
this information, because you will be using it in part of your formal lab report.
Results & Data:
Create a data table that you will use to keep your data. Data should be both qualitative (descriptive) and
quantitative (numbers). Keep in mind the type of data you will be collecting based on the problem you wrote
above.
You will be creating a line graph to illustrate your group’s data. The line graph will be generated using Excel.
Conclusion:
Please see the lab rubric for guidelines to writing your conclusion.
