LEQ: What physical properties of water
make it unique?
1. What disease do we associate with insulin and
glucose?
2. What disease do we associate with high
cholesterol?
3. What is one risk of using chemicals for agriculture?
Take a look at the following chemical reaction:
6CO2 + 6H2O  C6H12O6 + 6O2
4. List the reactants.
5. List the products.

2. Track your progress!
-1 = 96 -9 = 64 -17 = 32
-2 = 92 -10 = 60 -18 = 28
-3 = 88 -11 = 56 -19 = 24
-4 = 84 -12 = 52 -20 = 20
-5 = 80 -13 = 48 -21 = 16
-6 = 76 -14 = 44 -22 = 12
-7 = 72 -15 = 40 -23 = 8
-8 = 68 -16 = 36 -24 = 4

(density, solubility, specific
heat, surface tension,
buoyancy)

17. Number your paper 1-10 (do not skip lines)
1. Water molecules push up on a surf board,
causing it to float on the surface of the water.
2. Water striders can “walk” or glide on top of
water because of this property.
3. Even in the middle of a hot summer day,
water stays cool because of this property.
4. You can easily dissolve salt into water
because of this property.
5. Warmer water rises up to the surface
because of this property.

18. 6. Water molecules push up on speed boats, causing
them to float on the surface.
7. Ammonia is a difficult chemical to dissolve, but it
is easily soluble in water because of this property.
8. Even in the middle of winter, lakes and ponds stay
warm enough for fish to live in them because of this
property.
9. You can rest a paper clip on the top of a glass of
water because of this property.
10. Colder water sinks down to the bottom of a glass
because of this property.
