Drop It Like It’s “Hot Spot”
Objective:
Relate hot spot with plate tectonics.
Materials:
• alcohol lamp • test tube • test tube holder
• bond paper (2 sheets) • match • water
Procedure:
1. Attach one end of the bond paper to the end of another bond paper.
2. Fill 3/4 of the test tube with water and heat it over an alcohol lamp.
3. While waiting for the water to boil, place the paper on top of the test tube. Be sure that
the two are in contact.
4. Once the water starts boiling and fumes are coming out, hold the paper in the same
position for the next 10 seconds.
5. After 10 seconds, move the bond paper very slowly and horizontally by 10 centimeters.
See to it that the paper and test tube are still in contact.
6. Repeat step 5 after another 10 seconds and observe.
Q36. What can you see on the surface of the bond paper?

Getting to Know Gases
Materials : 3 rubber balloons of the same kind,digital balance and balloon pump (optional).
1. Measure the mass of the deflated balloon using a digital balance with a
0.01 precision (sensitive up to two decimal places).
Inflate the balloon using a balloon pump and seal the opening by securely
twisting/looping the end.
3. Measure the mass of the inflated balloon using a digital balance.
Q1. Is the mass of the deflated balloon different from the mass of the inflated balloon?

ATOMS AND MOLECULES
Materials: M&M, water, glass
Procedure:
1. Pour enough room-temperature water into transparent glass so that water the water is
deep enough to completely cover an M&M.
2. Once the water has settled, place M&M in the center of the glass. Be careful to keep the
water and M&M as still as possible. Observe for a minute.
Q1. How does M&M’s dissolve in the water?
