This Weeks At Home Experiment: 9/15-9/19

Hi Super Scientist,

This week we worked on our volume skills and learned how to measure liquids and irregular objects using a graduated cylinder.  Have fun at home making colors

Materials

  • 9 small clear plastic cups
  • water
  • an eyedropper (that has mL) on sides..GO to the PHARMACY for ONE
  • food coloring: red, blue, & yellow

Before starting your experiment

  1. Take 3 of the cups and add 1/2 cup of water to EACH. Label one RED, the other BLUE, and the last YELLOW.
  2. Then add 5 drops of red food coloring to the RED.  Repeat with yellow and blue in their respective cups.
  3. The colors will act as your STARTERS
  4. Next Label the 6 remaining cups A-F

Color Making Time

Follow the steps below below using an eye dropper.  Remember to rinse out the eyedropper in between steps

  1. Into cup A measure 19 ml of red liquid.
  2. Into cup C measure 18 ml of yellow liquid.
  3. Into cup E measure 18 ml of blue liquid.
  4. From cup C measure 4 ml and pour it into cup D.
  5. From cup E measure 7 ml and add it to cup D and mix.
  6. From the BLUE STARTER cup measure 4 ml and pour it into cup F.
  7. From the RED STARTER cup measure 7 ml and add it to cup F and mix.
  8. From cup A measure 8 ml of liquid and pour it into cup B.
  9. From cup C measure 3 ml and add it to cup B and mix.
  10. Record the color and volume of each cup A-F into the Rainbow of Colors Table 1
