At-Home Activities

Can’t make it to the MOST? Want to keep the learning going after your visit? You’re in the right place! Explore our wide selection of activities that you can try at home or in your classroom – perfect for budding young scientists who can’t wait to visit the MOST!

To help, we’ve marked each activity by Materials Required (Basic, Medium, or Advanced) and by Complexity (Easy, Medium, or Advanced). All of our activities are designed to be inclusive and sensory-friendly, but we’ve put a Sensory Warning next to activities that might involve loud noises or other sensory triggers. 

A Note for Adults:

We recommend adult supervision for all science experiments, both for safety and for a better learning experience! Remember to ask questions before, during, and after the experiment about what they think will happen, what they notice/observe, and what they learned. Encouraging discovery and curiosity are fundamental to the learning process! 


Engineering & Design

Technical Drawing 101



[Description Coming Soon]

I-Spy City



[Description Coming Soon]

Dream Room



Kids can learn the basics of architectural drafting and design their own DREAM BEDROOM using this new activity sheet! This activity is perfect for future artists, engineers, and architects alike. A more advanced version of this activity is available (see “Technical Drawings 101”). 

Balloon Rocket




Explore how rockets BLAST OFF using Newton’s Laws of Motion in this exciting homemade rocket activity! (No jet fuel required!)

Marble Run Challenge



Draw up a design, gather supplies from around the house, and test your creation to see if it can move a marble 5 feet from start to finish. Check out some advice and examples from TinkerLab for inspiration. This activity is a great introduction to the engineering design process (part of the NYS Science Standards), and it’s also a fun challenge to try as a family!

Sort It Out



Young children are natural scientists — they observe, touch, test, ask questions, and explore! But at their age, STEM learning doesn’t have to mean rocket science – it’s about fostering their natural scientific thinking! Activities like Sort it Out help encourage observation, description, categorization, and classification – ideas that apply across all STEM fields!

Sandwich Maker



Kids too young to code can still start to learn the concepts behind how computers work! Try out this fun family activity to explore how computers follow directions “literally” — and how the end result can get pretty messy (and sometimes silly)!

Physical Science (Chemistry & Physics)


Seeing Sound

Bouncing Balls



Parents can introduce the scientific method at an early age — it’s as simple as guess, test, repeat! Capture your child’s love for bouncy ball fun in this experiment that introduces the concept of making and testing a hypothesis. (It’s a great pairing with the Scientific Method Song from Ready Jet Go on PBS!)

Math Scavenger Hunt [SF]:

Math isn’t just equations on a chalkboard – it’s all around us! Discover the geometry of daily life (and get off the couch!) with the MOST’s Math Scavenger Hunt — who knew math could be so moving?

Density Jar & Floating Eggs:

It’s time to SINK or SWIM! Explore density with two new colorful, magical hands-on experiments for all ages — using only basic kitchen ingredients! 

Invisible Ink:

Using basic chemistry, you can send “invisible” messages just like a secret agent… For younger children or a simpler method, try using a blowdryer instead of a candle flame.)

Making Room for More:

Everyone could use a little more chocolate right now, so we love this “Infinite Chocolate Bar trick” that we’ve seen making the rounds online! It may seem like magic, but it’s really the magic of MATH! Grab a chocolate bar (or paper/cardboard) and get to work on your very own infinite chocolate bar

Use the chemistry of soap to create milk paintings in this STEAM activity, perfect for teaching little ones about the power of soap AND bringing out their inner artist!

Bread Baking [SF]:

Baking can be a great family activity, and it’s an easy way to bring STEM learning into the kitchen! Behind every loaf of bread like the one in today’s activity, there is CHEMISTRY! Warm water reacts with the yeast, which feeds on the sugar and creates carbon dioxide bubbles. The warm water also forms gluten when combined with the flour, which helps hold the carbon dioxide bubbles inside the bread as it bakes — which is why the bread puffs up in the oven!  Check a slice of the bread once it’s baked for little air pockets – that’s the trapped carbon dioxide!
