Hands On Pumpkin Science

It's pumpkin time!  I absolutely love this time of year.  Routines and procedures have been established and my kindergarteners are ready to dive head first into our science units.  Our pumpkin theme is spread out over two weeks in October but it could easily be done in just one.  The prep is minimal.  All you need are a few different pumpkins (many grocery stores will donate the funnier looking pumpkins to teachers!), a tub of water, something to measure with (we use linker cubes), and some carving tools.

Week 1

Investigating the Outside of the Pumpkin

We begin the unit by observing the outside of the pumpkin and talking about what we notice.  Students discuss size, shape, color, texture, temperature, similarities and differences, etc.

As all good scientists do, we record our observations and investigation results in our Pumpkin Journals.

We also count the ribs (lines) on the outside of the pumpkin and measure the height using linker cubes.


Then comes the real fun!  Will the pumpkin sink or float?  We always make a prediction before testing it out.


We also learn about the life cycle of a pumpkin.  I love these's Read and Find Out" books for science topics.

Week 2
Investigating the Inside of the Pumpkin

Students love to get their hands on their learning.  They can't wait to get inside the pumpkin to find out what's in there!  Estimating the number of seeds is always a ton of fun.  It's great for counting to 10 and skip counting.  We use counting mats to help us keep track.


It's amazing just how many seeds can be inside a pumpkin!

Last, we work on labeling the parts of the pumpkin that we find.

After 2 weeks of pumpkin fun, we celebrate by roasting pumpkin seeds!

You can find all of the activities and journal pages in my Pumpkin Science unit.
