I have to admit, we don’t really do Valentine’s Day in our house. I’m not really a hearts and flowers kind of girl, but the kids are quite curious and excitable this year, so I’ve put together a small collection of fun and easy science activities for Valentine’s Day.
First up are super simple heart patterns. Cut out different colour and size hearts and use them to make heart patterns. If you want to mix it up a bit more, add some flower shapes too!
Heart shapes are also great for practicing cutting and those ever important fine motor skills.
Blow up a heart
How about blowing up a balloon with a heart drawn on or even a heart shaped balloon using the fizzy power of an effervescent tablet or baking soda and vinegar.
Coloured Valentine Flowers
Create pretty flowers for your Valentine with this super simple transpiration experiment. All you need to do is buy some white flowers and place them in a mixture of food colouring and water for a few hours. The petals will change colour as the coloured water travels up the stem into the petals!
Anyone for a heart shaped pizza? This is a great activity for learning about respiration as yeast is used to make the dough rise.
How fast does your heart beat?
How about learning about heart rate and how it changes with exercise with this fun investigation?
Where is the heart?
Can you draw around yourself and draw your heart in the right place?
Make your own stethoscope
Make a stethoscope and listen to your heart beating. Spiderman dress up is optional!
Valentine Candy Science
You could make a beautiful coloured heart with skittles or M & Ms.
Or, how about building a tower of candy using Valentine sweets and toothpicks?
Secret Valentine Messages
We had a lot of fun making these scratch art canvas pictures too.
Once you’ve made your secret message, create a delivery system for it. This could be a paper plane, parachute, zip line or even a motorized car.
Do you have any more Valentine’s Day Science ideas for us?
Red Ted Art has some brilliant Valentine’s Day resources for teachers and parents too!
