____________/10 points
Lab Objective
Students will:
1. Accurately measure liquid volume using a graduated cylinder
2. Make and record quantitative observations in a data chart
3. Make qualitative observations to describe the color of the liquid in each test tube
4. Work cooperatively with a partner
Materials:
1. Three glass beakers for each colored water (red, blue, and yellow)
2. 3 10mL graduated cylinders (one for each color)
3. Three eyedroppers (one for each color)
4. Six glass test tubes labeled A, B, C, D, E, and F
5. Test tube stand
6. Protective Eye goggles
Procedure: (Remember to use accurate measurements for all steps!)
1. Measure 19 ml of RED water from the beaker and pour into test tube A
2. Measure 18 ml of YELLOW water from the beaker and pour into test tube C
3. Measure 18 ml of BLUE water from the beaker and pour into test tube E
4. From test tube C, measure 4 ml of water pour into test tube D
5. Measure 7 ml of water from test tube E, pour into test tube D. Gently swirl
6. From the beaker of BLUE water, measure 4 ml of water and pour into test tube F.
7. From the beaker of RED water, measure 7 ml of water and pour into test tube F.
Gently swirl.
8. From test tube A, measure 8 ml of water and add to test tube B
9. From test tube C, measure 3 ml of water and add to test tube B. Gently Swirl
10. Have test tubes checked by the teacher. Teacher signature ________________
