I'm not a big fan of Valentine's Day, but I do love theming our science activities, so here are some fun Valentine's Day Science ideas for you to try.
Valentine's Day Crafts and Activities
Make simple, pretty patterns using hearts or flowers. Symmetrical hearts with patterns inside also work well.
I love this candy heart reaction from Inspiration Laboratories.
Rainy Day Mum has some lovely Valentine's Day themed sensory play activities.
There are some lovely marbled hearts over on Red Ted Art.
Blow up a balloon heart using Alka Seltzer. This can also be done with baking soda and vinegar or yeast and warm water.
Make some pretty flowers for your Valentine, using a simple transpiration activity.
If you buy plain white flowers and place them in water and food colouring, the plant transports the coloured water up its stem and into the petals by a process called transpiration. In just a few hours the white flowers will be transformed.
Make a heart-shaped pizza and learn about respiration at the same time.
Learn about heart rate with a simple exercise linking exercise to heart rate.
Ask children to draw around themselves to find where their heart is. They can then add veins and arteries to demonstrate how blood flows around the body.
Children can make a stethoscope with an empty kitchen roll tube and a funnel.
Have some fizzy baking soda fun with an erupting baking soda heart?
Sticking with the fizzy theme, Valentine's Day love potions are always a big hit here!
Write secret messages for friends and see if they can work out how to read them.
I also have some simple Valentine's Day STEM challenges you might like.
Do you have any more Valentine's Day science ideas for us?
