Have fun growing sprouts on a sponge with our step by step Sprout House Science Project for Preschoolers. This sprout house craft is a full tutorial on how to make a sprout house with sponges while exploring the science of sprouting seeds.
Sprout House Science Project for Preschoolers
We have had an absolute blast with this STEAM activity with my preschooler. Honestly there are not a TON of science activities for preschoolers and toddlers like there are for the elementary age kids…when it really gets fun!!!
It’s super simple moms/teachers and your preschooler will LOVE it, I promise! I created a FREE Printable Sprout House Log for you to document the progress with your little ones. (to snag all of our FREE STEAM printables click HERE) 
Sponge Sprout House Materials Needed:
Sponges
Toothpicks
Chia Seeds (is what we used!)
Glass Pie Plate
FREE Sprout House Science Log/Journal (black/white or color)
How to Make a Sprout House with Sponges:
1- Place one sponge on a glass plate as the base of your sprout house and insert a tooth pick on either side. 
2- Cut a sponge in 1/2 and use one half of the sponge for your second layer.
3- Cut another sponge in 1/4’s and use one 1/4 to top off your sprout house.
TIP* lets be honest you can’t go wrong building your sponge sprout house, however you’d like!!! I’m just showing you our process for preschoolers.
4- Next using the two toothpicks, push through the bottom sponge, next the second sponge and so forth. This creates stability! This step can be hard so your little preschoolers may need a helping hand!
You are teaching the basics of Engineering for Preschoolers through letting them build their sponge sprout house. If you have older preschoolers give them the liberty to build it how they’d like, by giving them the materials and letting them engineer and build on their own!
5- In a small bowl wet your chia seeds.
6- Let your little ones, with their hands, place the wet seeds all over the sponges.
7- Pour a little water into the bottom of your plate so water can soak into the bottom sponge.
8- Place a clear (like a rubbermaid container) of your sprout house and set in a window sill to create a green house affect. (sorry, I forgot to take a picture of this – use your imagination!!)
9- Water your sprout house when it’s dry, keep it moist!
10- Within just a couple of days you should begin to see seeds sprout.
11- Use the FREE PRINTABLE Sprout House Log to keep track of the science project and document the progress.
I took pictures every couple of days – as you can see – that even towards the end I let my preschooler explore her scissors by giving our sprout house a haircut! She had a blast!
I am so grateful I was inspired by The Stem Laboratory and her sprout house science project, for us to try our own!

We are a husband and wife team, pairing our strengths together to teach our preschooler in the most fun and engaging way we possibly can. The mister is a high school educator at Northlake Christian school in Covington Louisiana and over the Innovation Center, which is all things STEAM. I am a SAHM that blogs pretty much everything we do in our little paradise, from what we eat, to where we travel to how we teach our little one. We hope you are inspired to incorporate STEAM into learning with your children.
