NGSS.MS-LS1-8

Design an experiment to test the effect of sunlight on the rate of photosynthesis in a plant. What would be your control variable?

• The type of plant used

• The amount of water given to the plant

• The amount of sunlight each plant receives

• The temperature of the environment

How would you use the scientific method to determine the relationship between the mass of an object and its acceleration due to gravity?

• Calculate the force on different masses and measure the acceleration

• Drop objects of different masses from the same height and time their descent

• Increase the mass of an object while keeping the force constant

• Keep the mass constant and vary the force applied
