The effect of size on the effectiveness of diffusion Aim: To use agar blocks infused with 0.1 Molar sodium hydroxide (NaOH) and phenolphthalein to investigate the relationship between shape and surface area: volume ratio on the effectiveness of diffusion. Hypothesis: That for a cube of agar‚ the time taken for complete colourisation due to diffusion of HCl is directly proportional to the cubes volume. Materials: |A block of agar (10cm x 5cm x 3cm) with 0.1M NaOH and |1x 250mL

Dark Matter (Review) Dark Matter (Review) Kenneth Lathrom Kenneth Lathrom 6th Period Dark matter is the missing piece to the astronomical equation of galactic gravitation. Simply put it is the objects we do not know and cannot see that explain why the farthest planets don’t follow the “norm” and hurtle away from the center of their designated galaxy. Astrophycists have been looking for signs of these unseen particles. Having theorized that when two dark matter particles collide they

Egg Osmosis Lab The purpose of this lab was to demonstrate an example of a spontaneous reaction and its connection to metabolism; in this case it was osmosis. The procedures that we used to complete the experiment were taking five eggs that had been soaked in a sucrose solution and then placing each one in containers of sucrose that each had different levels of concentration. The mass of each egg was measured before being placed into the solutions and then every 10 minutes after until they had soaked
