Science Workshop - Bubbles

Today some of the children in the Prep neighbourhood participated in a workshop about bubbles. We brainstormed what they know about bubbles. They learnt the science behind why a bubble is occurs. The children created their own bubble wands and made their own bubble solutions. The children hypothesised how a good formula would be made and then tested it out.

The Preps discussed what they know about bubbles.

• You can eat them (bath bubbles).
• You can blow them.
• They are a circle and clear colour.
• You dont have to blow into them the wand to make bubbles, you can move your arm and the air gets trapped and still makes a bubble.
• Air is trapped in the water and the sea because the fish blow the air out.
• We find bubbles in the sink when we wash our hands.
• There are bubbles trapped inside fizzy drinks.
• We can easily pop bubbles with our finger.

How are soap bubbles made?

 

Bubbles are pockets of soap and water that are filled with air.

When soap and water are mixed together and air is blown into it, the soap and water forms a thin skin or a wall that traps the air creating a bubble.

 

Here are links with bubble experiments that you might like to try at home.
