Scientific Method: Oreo Lab
The Scientific Method can be broken down into the following parts:
1.
2.
3.
4.
5.
State the problem.
Form a Hypothesis.
Experiment!
Record and analyze data.
Communicate the results.
Introduction
In this activity, you will follow the steps of the scientific method to discover if
double stuffed Oreos are really double stuffed. It will show you how scientists
record data on charts, make graphs, and draw conclusions. Do not eat the Oreos
until you are permitted, because it will affect your results.
Objectives
1. Name and describe the steps of the scientific method.
2. Follow the steps of the scientific method to solve a problem.
3. Record data in a table.
4. Construct a graph that shows the results of the investigation.
5. Write a conclusion of your results.
Materials
1. 3 double stuffed Oreo per student
2. 3 regular stuffed Oreo per student
3. Balance
4. Graph Paper for each student
Procedure
1. Gather Materials
2. Carefully twist of one side of the cookie from both Oreos
3. Measure the mass of the cookie with no filling on it for both cookies using the
balance. Record in the data table using grams.
4. Measure the mass of each cookie with the filling on it using the balance.
Record in data table.
5. Calculate the mass of stuff by subtracting the mass from the cookie +stuff
mass.
6. Repeat steps 1-5 three times.
7. Using the data table, graph your results as a bar graph.
8. Write your conclusion.
