1. Lab Station # 1: Toothpick 1.Obtain a toothpick from the beaker and break it into several pieces. Discard the broken pieces in the waste beaker. 2.Record your observations of the broken toothpick.

2. Lab Station # 2: HCl + Mg 1.Take a clean test tube. Put it in the test tube rack. 2.Using the tweezers, take ONE piece of Magnesium (Mg) chunk and put it in the test tube. Close the cap to the container. 3.Using a pipette, add just enough Hydrochloric Acid (HCl) to the test tube to cover the Mg chunk. (about one squeeze-full). 4.Observe the test tube closely for about a minute and record your observations. 5.Feel the bottom of the test tube with the palm of your hand and record your observations. 6.Dump the waste into the waste beaker. Rinse the test tube and place the clean test tube upside down in the test tube rack.

3. Lab Station # 3: NaCl + AgNO 3 WARNING: SILVER NITRATE STAINS SKIN AND CLOTHES. USE CAUTION! 1.Measure 10 mL of Sodium Chloride solution (NaCl) into a graduated cylinder using a pipet. 2.Pour it into a test tube. 3.Carefully add 2 drops of silver nitrate (AgNO 3 ) to the tube. Record your observations. 4.Dump the contents into the Waste beaker. Thoroughly rinse the cylinder and the test tube. Put the tube upside down on the test tube rack.

4. Lab Station # 4: Sodium Chloride-Water 1.Add about 100 mL of water to an empty beaker (take water from the sink). 2.Add 1 small scoop of sodium chloride to the beaker. 3.Using the plastic stirrer, mix the contents of the beaker until the sucrose dissolves. 4.Record your observations. 5.Dump contents in the sink and rinse the beaker out thoroughly.

5. Lab Station # 5: Candle 1.Use a match to light a candle. Dispose of the used match in the waste beaker. 2.Observe the lit candle for about a minute. Then blow out the candle. 3.Record your observations. HINT: This is a tricky one!!!! Pay attention to everything that’s going on and make careful observations here.

6. Lab Station # 6: Acetone and Styrofoam 1.SLOWLY pour acetone into the 100 mL beaker to about 1/3 of the way. 2.Take one Styrofoam peanut and put it in the 100 mL beaker. 3.Record your observations. 4. Pour the contents into the Waste beaker.
