Snowflake Crystal Ornament Science Project
Use common household items to grow crystals for a sparkly snowflake ornament. First, make a super-saturated solution. A solution is a liquid (solvent) with a solid (solute) mixed into it. Our solution is super-saturated because no more of the solid (solute) can be mixed in; it's reached saturation. Crystals form as a result.
What you need:
What you do:
- Make a supersaturated
solution of Borax and water by having an adult help you use the microwave to
heat about 200 ml of water until boiling. Use caution when removing the
glass from the microwave, because it will be hot! Mix in teaspoons of Borax
until no more will dissolve. Allow the solution to cool.If you're using a petri
dish, use it as a template to cut your filter paper (or coffee filter) down
to size so it will fit inside. Then fold the paper in half 2-3 times and
snip the edges thinking about where the cuts will appear when you unfold it.
You may want to practice on scratch paper first and figure out where to cut
to come up with the best snowflake design.
- Unfold your snowflake and
place it in the petri dish (or on the plate) and carefully pour the
supersaturated solution over the snowflake, making sure it's completely
- Let the snowflake sit in the
solution for an hour or longer until it's covered in crystals. Pour off the
solution and use a butter knife to carefully remove the snowflake. Place it
on paper towels to dry. You may need to use a toothpick to knock crystals
out of the snowflake's holes.
- Once it's dry, feed fishing
line or string through the snowflake and hang your ornament on your tree. Or
if it's a gift, wrap it up for Christmas!
