Buoyancy experiments for kids

This super easy salt water experiment is the perfect science activity to teach kids about the density of salt and fresh water. Great for an ocean unit!

Sometimes objects sink because they're heavy, but other times it's because they are buoyant! This buoyancy for kids experiment helps explain why.

Your kids will love these Buoyancy Science Experiments. This fascinating concept explains why some objects float while others sink. Explore buoyancy with these fun, hands-on activities that make it easy for kids to see science in action! Perfect for adding to your simple science experiments.

Make a diving squid that really sinks and rises! Awesome kids' science experiment and buoyancy activity.

Set up this soap powered boat to explore surface tension with kids! A soap boat is a fantastic easy science experiment for home or classroom.

Boat Experiments: STEM Activities for Kids - fun science experiments that kids can do at home related to boats and buoyancy. Great for the bathtub or kiddie pool!

This beginner physics experiment is easy to set up and a fun way for tots to learn how to make predictions and observations about density and buoyancy.

Kids will have fun learning about what floats in water with this fun density for kids unit exploring mass, volume, density, and more with four different fun, science projects for kids. This simple density experiment for kids is fun for preschool, pre-k, kindergarten, first grade, and 2nd grade students. Children will figure out what is less dense than water and they explore this scientific principle!

This easy buoyancy activity for kids lets them learn about a scientific principle while also having fun. Learn how to build a boat and which shape makes it float the best. Great for a quick STEM challenge for kids or a unit study on STEM design.

This simple buoyancy kids' science activity requires just a few common household supplies. Kids will love learning why things sink and float!
