21. Homework
Make up triad 2 work for the semester due Nov 13.

22. Today’s Work
Safety test review
Ice lab part 1
Collect all work

23. Lab 1 Measuring mass of ice
Calculate the mass of the ice:
Tare = weight of beaker
Balance reading gross = ____
Balance reading tare =______
Subtract gross-tare = net = mass of ice

24. Lab 1 Melt rate of ice Find the mass of the ice
Put ice and water in beaker and heat.
Measure time to completely melt.
Divide mass / seconds = rate of melt in grams per second

25. 1. Place measured dry ice into cup. Add ½ cup of water
1. Place measured dry ice into cup. Add ½ cup of water. Observe & record Add 3 drops of soap. Observe & record.

26. Vocabulary Motion 2. Speed 3. Velocity 4. acceleration
5. Force 6. Newton (N)
7. Net force
