Here are some fun activities students can try at home.

  • Science & Technology
    • Book Blast Experiment

      There's air all around you - but how much do you really know about it?  Learn more with science projects for kids.

      When you think of air, you might think of emptiness, but air is actually exerting a force - or pushing - on everything, all the time.

      Compressed air has great strength. The book blast experiment is a science project that demonstrates just how powerful it can be.

      Book Blast

       What You'll Need:

      • 3 books
      • Large airtight plastic bag

      Steps

      Step 1: Challenge a friend to move 3 books stacked on top of one another on a table by simply blowing at them. Of course, your friend won't be able to do it!

      Step 2: Place a large plastic bag on the table, and put the 3 books on the top of the bag. Leave the open end of the bag sticking out over the edge of the table.

      Step 3: Hold the opening together, leaving a hole as small as possible. Blow into the bag. Take your time; stop to rest if you need to.

      If you blow long and hard enough, the books will rise off the table. They will be supported by the compressed air in the plastic bag.

    • Unspillable Water Experiment
      Air pressure can be stronger than gravity. This unspillable water experiment demonstrates its strength as it keeps the contents of a water glass in place, even upside down.

      Water Experiment

      What You'll Need:

      • Juice glass
      • Water
      • 4x6 inch index card

      Steps:

      Step 1: Fill the juice glass full of water. Let the water run over so that the lip of the glass is wet. Be sure that you fill the glass right up to the top.

      Step 2: Place a 4x6 inch index card on top of the full glass of water. Be sure to press the card down securely with your hand, so that it makes a good seal all around the wet lip of the glass.

      Step 3: Working over a sink, hold the card in place with one hand as you turn over the glass. Carefully let go of thew index card. The card will stay in place, and the water will stay in the glass.

      What happened? The force of air pressure against the card is stronger than the force of gravity on the water. The air pressure holds the card in place.

      In fact, the force of air pressure is so great that you can even use it to crush a can. 
    • Caved-in Can Experiment
      Air pressure is strong enough to bend a can. Find out how you can amaze your friends with the caved-in can experiment.

      Crush a can


      What You'll Need:

      • Large container
      • Water
      • Ice cubes
      • Empty soft drink can
      • Measuring cup
      • Stove
      • Tongs or pot holders

      Steps:

      Step1: Fill a large container with water and ice cubes. Set it aside to use later.

      Step 2: Pour 1/2 cup of water into an empty soft drink can.

      Step 3: With adult supervision, put the can on a burner on the stove.

      Step 4: When the water in the can starts to boil, you will see steam coming from the hole in the top of the can. Turn off the stove, and use tongs or pot holders to remove the can from the heat.

      Step 5: Quickly put the can in the container of ice water, turning it upside down to rest on its top.  Now, watch the can collapse as it cools.

      What happened? When you heated the water in the can, it produced steam that forced the air out of the can.

      When you put the can in the ice water, its temperature lowered, and the steam condensed back into water.

      The pressure of the air outside the can was greater than the air pressure inside the can. The weight of the outside air crushed the can.

  • Numeracy
    • Helping your child with Counting
      One of the earliest skills children have to develop is counting. To "count" we need to match the number words with the correct number of "things", then we need to remember the numbers in order.
    • Helping your child with Space
      Mathematics is also about ideas relating to shapes, objects and their position. Children need to be able to describe shapes and objects and their position.
