Students love making this little 8 page pumpkin book to complete math centers about pumpkins! Eight pages that can be cut and stapled at the top corner include pumpkin weight, pumpkin circumference, pumpkin observation, sink or float, pumpkin height, pumpkin seeds, and a fun page to draw their pumpkin. The final page can be used to draw a jack-o-lantern if you decide to carve or decorate the pumpkins. This activity gives a lot of flexibility to the teacher to complete each activity or to remove activities. Each student can bring their own pumpkin. Teams of students can complete the activities with a "Team Pumpkin" or you can even use 1 pumpkin and complete the activities as a "Class Pumpkin".
Pumpkin Weight - use a scale to weigh the pumpkin(s).
Pumpkin Circumference - have students cut a string they think will fit around the middle of their pumpkin. Students measure their string to find their prediction. Then try the string around the pumpkin. Decide if the string (their prediction) was too small, too big or just right.
Pumpkin Observation - Use as many of the five senses to describe your pumpkin like a scientist would.
Sink or Float - Students make a prediction and then place the pumpkin in a tub of water to complete the experiment. I always talk with the kids about why the pumpkin floats (air inside like a beach ball).
Pumpkin Height - Students first predict how many Unifix cubes will equal the height of their pumpkin. Then use the cubes to measure the actual number of cubes needed to measure the height of the pumpkin. Take a step further and have students measure the height of the connected cubes with a ruler in inches or centimeters.
Pumpkin Seeds - Estimate how many seeds are inside first. Then, open the pumpkin(s) and remove the seeds. Encourage students to count out groups of 10 to make counting the large number of seeds easier.
Draw Your Pumpkin - A fun page that can be put at the beginning of the book or at the end. Flexible, since it can be used to draw the pumpkin before the experiments. It can also be used to draw a carved jack-o-lanturn or a decorated pumpkin at the end of the experiments.
