• Manipulated:
Type of Oreo – double stuf or regular.
• Responding:
The mass (g) of the filling.
• Controlled:
– Triple-beam balance
– Method used.
• Write a hypothesis using the IF,
THEN, BECAUSE format.
• IF the filling of double stuf and regular
Oreos is measured 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
