Online Science Class for Preschoolers--Supply List

Only two more weeks until I start my Online Science Class for Preschoolers!  I would be so thrilled if you joined us!  I have tried to make most of the supplies household items--I know some homes don't have toy dinosaurs, but I suspect if you have preschoolers or toddlers you just might have toy dinosaurs also.  I do know, however, that not everyone has two drawers of fossils or a bucket of seashells in their schoolrooms.  I decided to post this list of supplies so you can have time to look through it and pick up anything you might want.  I designed most of the lessons with 1-3 experiments or studies for your preschooler.  If you don't want to pick up the supplies, you can just do other activities/experiments.  This also makes adapting the class for younger children very easy: simply choose the experiments and activities that your child can do.  
I have highlighted in yellow the supplies that I suspect may not be common in homes with preschoolers.  If you have any questions or comments, I'd love to hear from you in the comments.  You can also send me an email at

Sounds like fun! My kids are 13 and 17 and I no longer work at a preschool so I don't need the class but I hope you have a blast! Also, when I was a Program Coordinator for a Toddler program, I taught a class for the childcare counsel called "Science For Young Children" at a conference. All the participants loved it and couldn't wait to bring my ideas back to their classrooms! If you want any ideas, let me know!

I am looking forward to it for sure!

Thanks, Nicki! I have this class planned out, but I would **love** to see your ideas. I'm considering doing another fall or winter class. I'll email you.

Me too, Aliesha! I've been testing the lesson plans during the last few weeks and we have had a fabulous time with them!!
