Ice Experiments For Little Scientists
Cold and rainy weather may mean more time spent indoors but that needn't interrupt your family STEM (Science, Technology, Engineering and Maths) fun! Could there be a better time than the depths of winter to explore the wonder of ice? Curious minds can discover the intriguing science of temperature, freezing points, states of matter and chemical reactions. Here are Team Trunkaroo's favourite ice experiments for little scientists:
Making Frost (via Trunkaroo)
Explore the cool relationship between H2O and salt! Petite professors can discover how to make frost by adding 4 tablespoons of salt to a tin can half-filled with ice. Stir for 30 seconds and then watch with amazement! The salt tries to melt the ice to make a solution, but when salt is added to ice it lowers its melting point and a very strange thing happens! The ice mixture becomes even cooler and forms frost on the outside of the can instead of dew. See instructions below or download printable here.
Ice Excavation (via Crafts On Sea)
Help your toys escape from an ice mountain! Develop problem-solving skills by freezing some (preferably durable plastic) toys in tubs of water and mounting an ice rescue mission. Mini makers can get busy with a rescue kit of salt, warm water, tweezers, a syringe and a magnifying glass. Kids will have a blast trying different ways to melt the ice. Which method works the best?
Ice Colour Theory (via Red Ted Art)
An icy experiment is a fun way to teach kids about primary and secondary colours, and colour mixing. Use food colouring to freeze red, yellow and blue ice cubes. Split different combinations of colour into separate jars: red and yellow, blue and red, yellow and blue. Watch as they melt and new colours develop! Make sure to wear an apron, as this activity can get messy.
Engineering A Christmas Ice Lantern (via Steam Powered Family)
This project will put children’s engineering skills to the test whilst creating a beautiful outdoor Christmas decoration. You will need two plastic cups, one small and one large, pipe cleaners, tape, water, food colouring and small decorations such as beads and pom poms. Make a pipe cleaner spiral inside the large cup, and thread on beads. Try balancing pom poms on the pipe cleaner. Next place the small cup inside the large cup and tape in place to keep flush. Fill the large cup with water and add a few drops of food colouring- then freeze!
Making Ice Grow (via Teach Preschool)
Demonstrate the change of matter and freezing process using this cool experiment! Little scientists will love watching ice grow as water freezes upon contact.
Blow A Frozen Bubble (via What We Do All Day)
When the temperature is low enough a bubble will freeze a few moments after you blow it. This is an awesome way to learn about temperature and freezing points. If the temperature outside isn’t below 0°C then you can blow the bubbles onto a plate and put the plate into the freezer. A regular bubble wand and solution will do the trick!
