Activity 1.2 Racing M&M colors Do some M&M colors dissolve in water faster than others?

Materials Needed for Each Group 6 Different colors of M&M’s 6 White plastic or foam dessert plates Room-temperature water Round film canister lid or a quarter 1 Plastic cup, 31/2 ounces Crayons or colored pencils Permanent marker Bucket or large bowl Paper towels

What do you notice? Draw a “I Notice I Wonder T CHART on the right side of your journal. You will write down your observations here. Draw a picture of your M&M’s and make sure That you label your drawings! Water Date Plate I Notice I Wonder Yellow M&M Page # Page #

Procedure 1. Draw two concentric circles and a dot on each plate so that you can better compare how fast the coating from each color M&M dissolves in water. You will need one targeted plate for each color M&M you plan to race. ● Use a permanent marker to trace around the top of a 31/2-ounce cup to draw a circle in the center of a plate. ● Place a quarter, film canister lid, or other similar-sized circular object in the center of the circle you just drew. Trace this object with a permanent marker. ● Make a dot in the center of the circles on each plate.

Procedure Pour enough water into each plate so that the bottom of the plate is completely covered. With the help of your lab partners, place a different colored M&M in the center of each plate at the same time. Observe for 1 minute.

What do you notice? Write down your observations in your science journals. Make sure and draw your observations and label them! Water Date Plate I Notice I Wonder Yellow M&M Page # Page #

Share Your Observations ● Does one color seem to move faster/slower than the others? ● Did other groups have similar results? ● Is there enough evidence from your experiments to conclude that a particular color of M&M moves faster in water than the others?

Clean Up! Clean up your area. Make sure all trash is thrown away. Wipe off your desk and make sure there is not any water left on the top! All journals should be returned to your class on the cart.
