Materials:

  • 1 double stuf Oreo

  • 1 regular Oreo

  • Triple-beam balance

  • Ruler

  • Calculator

Procedure:

  • Gather lab materials.

  • Carefully twist off one side of the cookie from both Oreos.

  • Measure the mass (g) of the cookie with no filling on it for both cookies using the balance.

  • Record the number of grams in the data table.

Procedure:

  • Measure the mass (g) of each cookie with the filling on it using the balance.

  • Record the number of grams in the data table.

  • Calculate the mass of filling by subtracting the cookie mass (g) from the cookie + filling mass (g).

  • Record the difference (g) in the data table.

Procedure:

  • Record the results from 3 other groups.

  • Calculate the average mass (g) of filling and record this value in the data table.

Hypothesis/Prediction

  • Write a hypothesis using the IF, THEN, BECAUSE format.

  • IF double stuf and regular Oreos are compared THEN the double stuf Oreo will have twice the amount of filling of the regular Oreo BECAUSE Nabisco isn’t allowed to falsely advertise their cookies.
