Research Question
How can temperature affect the rate of diffusion of a solution in agar cells? 
Introduction
Our hypothesis
Is “If the temperature is increased then the rate of diffusion will follow due to the added energy to the agar molecules.” It is justified by the added energy to molecules due to the increased temperature.

Methods
With a knife, slice a cube of agar measuring 3x3x3cm. Be sure to cut as accurately as possible.

Pour 200 mL of 0.1M sodium hydroxide solution into the beaker.

Measure the temperature of 0.1M sodium hydroxide to find the room temperature
Place the beaker filed with 0.1M sodium hydroxide onto the hot plate/heater/stove.

Take the beaker off once the temperature has reached 40 degrees Celsius (104 degrees Fahrenheit)
Place the cube of agar in the 250mL beaker filled with 0.1M sodium hydroxide and wait 5 minutes.

Once five minutes has passed, take the block of agar out of the beaker and place on a plate.

Cut the piece of agar in half and measure the amount of diffusion took place in the agar.

Record results and redo the experiment 3 additional times to see if your results are precise.
