1. Safety in the Science Lab (vocabulary terms)

2. Concentration-amount of material dissolved in another material.
Example: 1mL of food coloring dissolved in 100mL of water is not as concentrated as 25mL of food coloring dissolved in the same volume of water.

3. Corrosive-material that dissolves or eats through another material.
Sulfuric acid is a corrosive chemical that can burn through metal or skin.

4. Flammable-catches on fire easily
Example: Gasoline is a very flammable
material that catches on fire easily.

5. Fumes-visible or invisible vapors
Example: Robert could smell the fumes of
the sulfur because it was not kept in a tightly-sealed container.

6. Toxic-poisonous
Example: Toxic household cleaners like bleach and ammonia should be kept away from children because if swallowed they can cause sickness and or death.

7. Ventilate-to cause air to move in and out easily
Example: Open the window so we can ventilate the room.

8. Volatile-easily changing into a gas or vapor
Example: Alcohol is volatile because it is a liquid that evaporates into a gas easily.

9. Wafting-gently moving the air back and forth with your hand
Example: Wafting is a better way to check for a substance’s odor because the gas is not as concentrated when it enters your nose.

10. So….how was science lab today?
