1. Lab Equipment

2. Beaker Graduated Cylinder

3. Triple Beam Balance

4. Test tubes Pipettes

5. Water Lab

6. Cohesion
The attraction of a molecule to itself

7. Adhesion
Attraction of a molecule to another substance

8. pH Measure of how acidic or basic the substance is Scale is 1-14
1 strong acid
14 strongest base

9. pH Litmus or pH paper is used to identify the pH of a liquid
Blue = Base
Red = Acid

10. Polarity A partially charged substance. One side partially positive
Other side partially negative

11. Polarity Opposite sides are attracted to one another
Similar sides repel each other

12. Organic Molecules that contain carbon.
All living or once living organism contain organic molecules (carbon).
Water does not cause a reaction with organic material.

13. Chemical Reaction Substance is broken down or formed
Burning a piece of paper

14. Physical Reaction A substance is physically changed
Tearing a piece of paper

15. Solubility The ability of one substance to dissolve into another.
The solute is the substance that is being dissolved.
The solvent is the substance doing the dissolving

16. Density Measure of how tightly packed together a substance is
Lead: very dense
Styrofoam: Very light

17. Calculate Density Density = Mass of liquid / Volume of liquid
D = 12g / 2ml
D= 6g/ml
