Valentines Day Viscosity Experiment and Liquid Density Science Activity

The fun thing about science experiments for young kids is that you can set them up easily and quickly with what you already have! This Valentines Day viscosity experiment is perfect for a little bit of kitchen science. We love holiday themed science activities because they are so much fun and very festive!

Valentine’s Day science experiments can be quite simple but very educational. I love science activities that feel like play time too. It’s a wonderful way to introduce science to younger kids. Your little scientist will love these ideas.

Supplies for this quick Valentines Day viscosity experiment

Small, clear plastic cups

Small plastic hearts {table scatter}

Various liquids from around the house that you know have different viscosities such as water, dish soap, oil, glue, hair gel, corn syrup, and anything else you can find!

Paper and pencil for tracking results which is great for an older child, but we are still with the basics and keeping it playful

This Valentines day viscosity experiment checks out different fluids around the house and compares them to each other. Add colorful little hearts to really get a good look at what viscosity is all about.

What is viscosity? Its the thickness of a liquid! Hair gel is much more viscous that oil and especially more than water!

LIQUID VISCOCITY

Kids can certainly help to set up this Valentines Day viscosity experiment. Talk about viscosity and provide examples. Have your kids search around the house for a variety of liquids. If you want to try this with a class, you can provide a variety of liquids kids can choose from.

Kids can help pour liquids too. Pouring the liquids is a great opportunity to really check out their viscosity! Less viscous liquids will pour faster than more viscous liquids.

You can also take it a step further by dropping in these little hearts. It’s for Valentine’s Day after all?! Do the hearts sink or float? What other objects can you test, how about a paper clip.

Will different weight objects move differently through the different liquids? Which liquid suspends the hearts the best. Our favorite for this was the hair gel {extra hold gel}!

LIQUID DENSITY SCIENCE

This science activity also brings up the idea of liquid density. The denser the liquid the easier it is for an object to float. Which liquid is the densest that you have set up in your experiment.

The corn syrup was pretty good too, but our hearts are pretty light. Even if we poked them down into the corn syrup, they would slowly rise up over time.

The dish soap and glue were so-so. One heart sank and one floated. My son found it delightful to poke the hearts down into the thicker liquids to see what they would do. These little hearts can be used in other fun early learning activities.

Most of the liquids can be saved and poured back into the appropriate containers, so there is very little waste. Quick and easy science! I love science experiments I can whip up in minutes but also gets us thinking and exploring.
