Valentine’s Day STEM Activities for Kids

Grow crystals heart shape

This awesome activity teaches recrystallization and chemical reactions! Recrystallization happens when a solution of compounds can be dissolved in hot water and then cooled. As it cools, one substance crystalizes (the Borax) and can be removed from the rest of the liquid, which holds the other compound.

Materials:

– 3 cups of water

– 1 cup of Borax

– Pipe cleaners (red and pink)

– Clear jars or cups

– String

– A stick to hold up your creation (a pen, popsicle stick, etc.)

 

Instructions:

Boil your water. Add Borax and stir periodically until completely dissolved.  Set aside to cool slightly. While the water/borax combination is cooling, make your heart shapes out of pipe cleaners. You can do this from memory, drawing a heart shape and following the edges of a sheet of paper. Tie a piece of string to the top of your creation. Pour the water combination into your jars. Put the pipe cleaner heart shape into the filled jar leaving the string outside of the water. Tie the string to your stick. Keep in a safe location for 1-2 days and watch as your pipe cleaner grows crystals!

Vday suncatcher

Materials:

  • Tissue paper in various colors (pink, white, red)
  • Scissors
  • White glue
  • Paint brush
  • Wax paper

 

Instructions:

Cut various colors of tissue paper into small pieces. Use colors of tissue paper that go with your theme. For this tutorial, I chose reds, pinks, and whites to make heart suncatchers for Valentine’s day.  Lay a sheet of wax paper on a flat surface.  Pour some glue onto a portion of the wax paper. Spread the glue into a thin layer using a paint brush. Place a few overlapping pieces of tissue onto the section with glue. Brush on some more glue over the pieces, smoothing them around the edges as you go.  Continue adding tissue paper pieces until you have made a collage that almost covers the entire wax paper or until you have got a big enough collage to make the intended number of suncatchers. Allow the collage to dry completely.  If you want suncatchers that are more see-through, you can carefully peel off the tissue collage from the wax paper once completely dry. Leaving the wax paper on is perfectly okay—the suncatchers will still catch some light, though not as much as wax paper-free ones.  Cut shapes out of the tissue paper collage. You can put a border in the shape of a heart and then cut it out. Punch a hole near the top of the suncatcher and hang it with a ribbon or string.
