Properties of water Notes
Atom: An atom is the smallest unit matter that retains its properties, atoms consists of protons, electrons and neutrons.
Protons: Has a positive charge.
Electrons: Has a negative charge.
Neutrons: are neutrally charged.
Ions: Atoms are usually neutrally charged because of the number of protons and electrons are unevenly shared atoms called atoms.
Hydrogen Bonding: Is the weak attractions between the weakly positive hydrogen atoms and the negative oxygen atoms.
Cohesion: Water molecules addicted to more water.
Surface Tension: Small critters that can walk on water
Adhesion: Water that can also go to other materials.

Investigating water lab
Evaporate cooling: station # 1 Water and alcohol:
1. the alcohol fells a little cooler and the water was the one that you could of seen obviously.
2. because i think that it would have been way different if alcohol was going to be your sweat.
Water tension/cohesion Station # 2 Water on a penny:
3. my prediction of penny's is 25.
4. the amount of penny's that were held was 27.
Surface tension Station 3 Water on wax paper:
5. when i saw the wax paper and the water the water quickly turned into a bubble of water
Surface tension Station 4 paper clips on the surface of a cup of water:
6. i got 15 and then they all sank.
7. the soap goes to the bottom and you can start seeing the color of the soap.
Adhesion Station #5 Graduated Cylinder:
8. because of the adhesion making the water not straight.
9. i think cause the elements need to have different type of side.
Capillary Action Station #6 Rolled up paper towel
10. because if the water is in the bottom it will travel to the other side.

Introduction to Density Lab
Q: Is all the ocean water the same consistency? does water have the same amount of salt and/or temperature throughout?
A: No because all of the water goes in a different consistency, no because some salt is in different places and some water is cold and some hot.
LESSON OBJECTIVE:
be able to explain how density differences affect stratification.
MATERIALS:
A: No because all of the water goes in a different consistency, no because some salt is in different places and some water is cold and some hot.
LESSON OBJECTIVE:
be able to explain how density differences affect stratification.
MATERIALS:
- Two 250 ml beakers, one 500 ml beaker
- electronic scale
- glass string rod, spoon
- pickling salt, water samples (warm and cold) food coloring
- i pad for pictures
