Title - LEAFY GREEN
By - Judy Schneider
Primary Subject - Science
Secondary Subjects - Science
Grade Level - 6 - 8 (adaptable)
SCIENCE PROJECT OF THE WEEK
LEAFY GREEN
PROBLEM: Is green the only color in a leaf?
RESEARCH: Look up chlorophyll in a biology textbook. Look for other color pigments that might be found in leaves. Research the reason that leaves change colors in the fall.
HYPOTHESIS: What have you learned about the colors in leaves?
MATERIALS: 5 very different leaves
rubbing alcohol
1 strip of coffee filter paper
1 metric ruler
1 plastic glass
PROCEDURE:
1. Pour about two centimeters of alcohol into the plastic glass.
2. Scratch the leaf. Rub some of the green coloring onto the filter paper, about an inch from the bottom of the paper.
3. Wrap the strip of filter paper around a pencil or stick. Attach it with tape.
4. Lower the paper into the alcohol and rest the pencil on the sides of the plastic glass.
5. Be sure the rubbing alcohol does not touch the place on the filter where the leaf was rubbed. If the filter paper is too long, twist the pencil to keep the spot from the leaf rubbing out of the alcohol.
6. Watch the paper for five minutes and record any changes that occur. Record your observations about every 20 minutes until no more changes occur.
DATA: Record your observations in a data table. Be sure to attach a strip of filter paper for each of the leaves that you use.
CONCLUSION: This is not optional. You must explain what you learned by doing this activity.
Remember that you must answer the question you asked in your original problem statement.
NOTE: BE SURE TO HAVE YOUR PARENT OR GUARDIAN SIGNS YOUR WORK. PARENTS: YOUR SIGNATURE SHOWS YOUR STUDENT HAS DONE THE WORK.
TEACHER SECTION:
POSSIBLE HYPOTHESIS: Green is the only color in the leaf because that is the only color I can see.
POSSIBLE CONCLUSION: Students should discuss the colors that separate on the paper. There should be some discussion of the reason the colors come out in the fall.
