Every special occasion makes the perfect backdrop for creating theme science experiments and activities for young kids! Valentine’s Day is a perfect reason for spending a couple weeks exploring cool science concepts. We love science and STEM concepts that are easy to recreate at home with minimal and inexpensive supplies! We have 10 of the best Valentines Day science experiments and activities the kids will love.
THE BEST VALENTINES DAY SCIENCE EXPERIMENTS FOR KIDS!
Science is a big deal and can often be intimidating to approach with kids, especially at home. I try to make our activities as versatile as possible for home or classroom use.
There’s no reason a little science can’t be introduced at home and makes a great activity for a screen free afternoon. We have several resources for setting up science at home all year round, you can find these below!
MY LATEST VIDEOSKids and science are so important, so we want to make our simple science experiments so much fun! There’s a fun handful of science concepts that are perfect for the younger kids to be introduced to right away. They are playful and filled with visual impact!
Check out our awesome slime making video for Valentine’s Day!
MAKING VALENTINES DAY THEME SCIENCE!
It’s really as simple as choosing colors, adding confetti or glitter, and coming up with fun names when you go to set up Valentines Day science experiments. Love potions, hearts, cupid, you name it! Purple, pink, red or even green, blue, and yellow. It’s all up to you and what your kids love.
We enjoy using Valentine’s Day theme candy like conversation hearts, peeps, and gummy candy! You can see our candy engineering here.
Recreating simple and classic science experiments with a Valentines Day theme is a fun way to repeat science activities for better understanding. Get started with the ideas below and look for several new ideas this season as we lead up to February 14th!
VALENTINES DAY SCIENCE EXPERIMENTS AND ACTIVITIES
Below you will find our favorite and easy to do Valentines Day science experiments and activities. Click on the red links provided or the photographs to show you how to get started.
We are looking forward to adding a couple physics ideas as well this season as well as our favorite chemistry activities recreated with a Valentines theme.
We also have science theme and printable Valentine’s Day cards for kids to hand out! Totally free printable ideas, just pick up the supplies! We have several fun options including my favorite test tube science card that you can see just below.
Slime is an awesome chemistry activity for kids. Learn about polymers while making a super cool sensory play material. This is terrific hands on science that you can also experiment with too. We have a fluffy slime and a foam slime option for Valentine’s Day too.
LIQUID DENSITY AND CHEMICAL REACTIONS
Make a homemade lava lamp for Valentine’s Day and explore both physics and chemistry as you test out liquid density and a cool chemical reaction.
DISSOLVING CANDY VALENTINES DAY SCIENCE EXPERIMENT (PRINTABLE)
Another great Valentines day science experiment that explore solubility! We have a printable science journal page to go along with this one. Don’t worry! You don’t need test tubes either, clear plastic cups work.
BUBBLE SCIENCE WITH A VALENTINES DAY THEME
Blowing bubbles isn’t just for play time! It’s a great simple science activity too! Learn how to make a classic bubble solution and learn a bit about bubble science too. You could even make it an experiment by testing different bubble solutions.
COOL VALENTINES DAY CHEMISTRY EXPERIMENT
This is a mini example of the classic Elephant’s toothpaste style chemistry demonstration. However, you don’t need to find a special hydrogen peroxide to try it out at home! A few common household ingredients and you are good to go. The foam is totally safe and fun to play with too.
LEARN HOW TO GROW CRYSTAL HEARTS
This crystal hearts Valentines Day science activity is one of our most popular ideas! So pretty and makes a great science craft, growing these crystals is much easier then you might think. Growing crystals is another awesome chemistry activity that you can recreate with any theme.
SALT CRYSTAL HEARTS FOR VALENTINES DAY SCIENCE
For more hand on crystal growing that’s perfect for the younger scientists, try growing salt crystal hearts. It’s still awesome chemistry but great for kids who want a more hands on activity or who might be tempted to taste things.
WILL OIL AND WATER MIX? SIMPLE VALENTINES DAY SCIENCE
Will they mix? You find out! This Valentines science activity is quick to set up and is similar to our lava lamp activity but with more room to experiment and play.
VALENTINES DAY WATER DISPLACEMENT SCIENCE EXPERIMENT
Exploring the volume of a solid object! Water displacement is a fun way to experiment, discover, and observe changes in liquid levels with a Valentine theme object. Check the dollar store for hearts!
MIXING VALENTINES DAY LOVE POTIONS
Classic baking soda science with a fun theme to make it just a little different. Set out a buffet of items for mixing and experimenting. If you are brave, you can also add in oil and water! It can get a little messy, so you will want to make sure you have a good surface and paper towels.
GELATIN HEART DISSECTION FOR VALENTINES DAY
So this is one of our Halloween science experiments from earlier this year, but I thought it was really fun and fit the theme for Valentine’s Day too! Explore the science behind gelatin and engage in some creepy sensory play.
VALENTINES VISCOSITY SCIENCE EXPERIMENT
Gather a few random liquids from around the house including the bathroom and the kitchen. You could even try layering the different liquids to build a density tower and see which liquids are heavier than others. Lots from to experiment playfully.
This is just a sampling of the cool Valentines day science experiments we have going on over here! We also have more slimes, STEM challenges, and science to keep you motivated all season long. Check out a few more links below for extra ideas.
