Watermelon Theme Day
Overview of Activities:
1. estimate circumference
2. estimate number of seeds
3. complete watermelon color book
4. complete Willy Watermelon puppet
5. sponge paint watermelons
6. eat watermelon -save those seeds!
7. confirm predictions
8 watermelon prints using rind.
1. ESTIMATE CIRCUMFERENCE (math)
MATERIALS: watermelon, scissors, string, chart ( contains these three phrases:
too long, just right, too short). masking tape.
PROCEDURE: each student estimates the circumference of the watermelon by
cutting a length of string they estimate to be the
right size. Place a piece of masking tape on the estimate with the students
name. Fit the piece of string around the watermelon and confirm the
prediction. Place the string on the proper portion of the chart with another
piece of tape. When all of the predictions have been made and confirmed
discuss the chart. How many were too long, too short, just right? You can also
count by 5's using the strings across the chart.
2.ESTIMATE NUMBER OF SEEDS.(math)
MATERIALS: watermelon, chart or white board, writing instrument. Plates and
cutting tools, portion cups.
PROCEDURE: show the students the watermelon. Discuss watermelons and
seed. Elicit experiential conversation from students. Have each student
estimate the number of seeds s/he thinks are in the watermelon. Write down
the estimates. Confirm predictions: open the watermelon and eat. Have
students save the seeds by counting them into portion cups (10 seeds per cup).
Whole class - counting by tens to confirm estimations of seeds. Save seeds.
3.WATERMELON BOOK: (English Language Development., science..social
studies, fine motor skills)
MATERIALS: Willy Watermelon Book copied for each student. Crayons.
(Book found on internet at: www.watermelon.org)
