In the space below, list the unsafe practices as they occur. Check your answers with the video!

1. Obtain the following items from your teacher: 3 beakers with colored water- 25 ml of each color (red, blue, and yellow) 1 graduated cylinder (25 ml - 50 ml) 1 eyedropper 6 test tubes labeled A, B, C, D, E, and F
 * Measurement Lab **

2. Perform each step outlined below using accurate measurements. (1) Measure 17 ml of RED water from the beaker and pour into test tube A. (2) Measure 21 ml of YELLOW water from the beaker and pour into test tube C. (3) Measure 22 ml of BLUE water from the beaker and pour into test tube E. (4) Measure 5 ml of water from test tube A and pour it into test tube B. (5) Measure 6 ml of water from test tube C and pour it into test tube D. (6) Measure 8 ml of water from test tube E and pour it into test tube F. (7) Measure 5 ml of water from test tube C and pour it into test tube B. (8) Measure 2 ml of water from test tube A and pour it into test tube F. (9) Measure 4 ml of water from test tube E and pour it into test tube D.

If your group finishes the lab early, please take some time to visit this website and play a measuring game. I suggest playing the hard centimeters or super brain inches levels of the game.
