Ice is obtained on the 4th floor of the Biology department. There is a large cooler in the hall near the corridor that connects to the Chemistry department. The large pans are set on the floor to catch the water drops. The ice chest should also be set in one of these pans when not in use to catch any leakage. Each station needs 400g of masses.
Slotted masses work fine.
Use three 100's and two 50's at each station. Unless motion probes are attached to Port 2 students should go to 'collect' and then turn on 'Force only data'. Inform students to leave carts set up this way. One roll of tape is sufficient. Masking tape will probably leave less residue on the carts.
