Children’s attention spans ages 3 to 5 years are still relatively short.
This list includes 12 of the most popular science sensory activities for preschoolers that are quick and EASY to do.
They will be learning, engaged, and smiling from ear to ear.
More importantly, you may even inspire that little scientist in them. 🙂
Also, be sure to stick around until the post to access a BONUS science sensory resource to use!
1. Flour Sensory Tray
Activity By: Hands On As We Grow
You most likely have these items at home! Simply pour flour onto a tray.
Let your little one explore the soft powdery texture with their fingers by drawing or making hand prints.
Kick up the fun by adding baking utensils or small toys (like cars, animals, or trains) for your child to get creative with.
Items Needed: Flour, Tray
Promotes: Tactile Sensory Stimulation and Creativity
2. Shaving Cream Rain Clouds
Activity By: One Little Project
The sky’s the limit with the color combos you want to create for your kiddos!

Most of these items you can get at the Dollar Store or you may already have at home.
Debbie Chapman, with One Little Project, likes to “use a rainbow assortment of colors to create something beautiful.”
Directions:
- Pour water into a clear cup and top it off with shaving cream.
- In a few small one to two ounce containers add water.
- Then add different colors of food coloring into each small container (several droplets).
- Last, pour SMALL (super tiny) amounts of food coloring over the shaving cream using a syringe, eye dropper, or small measuring spoon.
By squeezing the small droplets over the shaving cream you won’t over saturate it or melt it too fast.
Watch in AWE as the gorgeous colors trickle through the shaving cream!
Items Needed: 1 can of shaving cream, Food coloring, Water, Clear glass, Small 1 to 2 ounce size containers, Eye dropper (you may also use a syringe or small measuring spoon)

9. Make Homemade Butter
Activity by: Mommy Poppins
I remember doing this activity when I was in 1st grade (probably because I’m a butter fanatic).
We all sat in a big circle and passed around a wooden jar that had heavy whipping cream in it.
Each of my classmates and teacher got a turn whipping the heavy whipping cream with the wooden jar stick.
By the end, we had butter! I was truly amazed.
My taste buds were in heaven as we got to enjoy that on bread with jam. 🙂
This recipe is super quick and easy …
Directions:
- One jar with a lid
- Pour heavy whipping cream into the jar
- SHAKE, shake, and shake until you have whipped butter!
The smaller the jar the faster it will take to make your butter.
For instance, a baby jar takes about 10 minutes to whip up.
For faster results or to support kids with upper extremity challenges, use a hand mixer for blending the heavy whipping cream in a bowl.
Items Needed: Jar with a lid, Heavy whipping cream OR bowl, hand mixer, heavy whipping cream
Promotes: Fine Motor Skills, Taste, Encourages focus

Very sensational and immersive experience. I can only imagine how great this will be for pre-schoolers aged 3-5. I loved how you expounded on the benefits of doing these activities and what to expect as a result.
This definitely felt like a science experiment.
I would love to see more images though — this would enhance some of the more explosive points. The only direction is up that is.
Wonderful! I appreciate your feedback. 🙂
This is a really excellent post! There are some really cool and easy activities here that can be completed with stuff in your cupboards right now. My daughter is a childcare worker and is always looking for cool things to do with her kids. I will definitely forward this site to her. She will definitely do these little experiments with her kids. Thanks for sharing, very cool article!
