Find Out Why Leaves Change Color - 0 views

taylorcmcanulty on 25 Jan 15This hands-on activity allows students to get a better understanding of why a tree's leaves change colors. By doing this activity, we will be able to see how a leaves colors stay hidden in the leaf all year long. Students will collect leaves prior to doing this experiment, and will place them in small jars filled slightly with rubbing alcohol. Those leaves will be chopped up into tiny pieces and left in the jar which will be covered with a lid or plastic wrap. The jars will soak in water for about a half an hour. Students will then use a strip of coffee filter paper to see the colors from the leaves bleed. They will see different shades of green, orange, red, and maybe some yellow depending on the type of leaf. I chose this experiment because it allows the students to understand chromatography, chlorophyll, and different pigments found in leaves. By doing a hands-on activity, students are more engaged and anxious to find out what is going to happen. I envision this experiment being used at the end of a plant lesson in science. We would have been discussing different types of plants, trees, flowers, and why they are all different colors. There will also be many important vocabulary words that the students will need to understand, which will be present in this activity. We will conduct this experiment in small groups so that students are able to participate and see what is going on.
