Hannah Zizlsperzer, NNHS '26 tests whether household items sink or float. Learn about buoyancy and density in this fun experiment!

Vivian Lin, NNHS '25 shows you through this fun experiment using a zipblock bag, a piece of paper, permanent markers, and a glass of water. Learn about refraction as you have fun drawing and experimenting with your zipblock bag!

Katherine Holt-Doucette, NNHS '25 walks you through this easy experiment using only one material: tape! Learn about what happens when you create a charge between two pieces of tape. Will they attract? Will they repel? Try it and find out!

We've created a new version of our popular At-Home Experiments video with brand-new science experiments! This video includes 16 engaging science experiments for preschool-grade 8 students to try. Child-friendly instructions and scientific explanations can be found in the video. 

In March 2020, when schools closed due to COVID-19, many of the STEMentors submitted videos of them doing their favorite science experiments for preschool-8 students to try at home! These experiments are hands-on and feel like play, while including advanced scientific processes in the reactions! Directions and an explanation document can be found at this link!

Mary Williams, NNHS '22 walks you through one of our most popular experiments! With just a plate, water, pepper, soap, and a spoon you can try this fun activity! Soap is so important to get rid of germs, and this video/experiment shows exactly why! 

In Summer 2021, we hosted 7 guest speakers who work in various STEM fields to discuss what they do and teach a kid-friendly STEM topic. In this recorded session, Mary Dunlop, PhD, a biomedical engineer, who  works in the field of synthetic biology teaches students all about DNA! Feel free to try out the fun strawberry experiment shown in the video!

In February 2021, we made a video submission Science Fair, and we got great entries from kids K-8! The experiment shown in the video is the result of an acid and a base reacting! All you'll need is paper towels, a ziplock bag, baking soda, vinegar, and food coloring (optional)! 

In Summer 2021, we hosted 7 guest speakers who work in various STEM fields to discuss what they do and teach a kid-friendly STEM topic. In this recorded session, Jason Rothman, MD, an ophthalmologist, teaches students all about how the eyes work!

Grace Davis, NNHS '22 reads through the book Left Brain, Right Brain from our K-3 Brain Health session. Although we use both hemispheres of our brain equally, this activity of figuring out if you're "right-brained" or "left brained" (metaphorically speaking) can be a great wait to learn about how you learn!

Mar Casajuana, NNHS '22 walks you through this blooming flower experiment! Capillary action, the adhesion of water to another material (in this case paper,) causes water molecules to climb up the paper to the outside, leading to the fibers in the paper expanding, opening the flower. This same process is in real flowers, as capillary action brings water up the roots! What color will you make your flower?
