2/16 A/B DayLEQ: 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.

Colder water = denser water
Water is the universal solvent!
The “skin” that covers water’s surfaceThe upward
push of water molecules on a substance
Water heats and cools very slowly!

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

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.

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.
