Second day at tech!

Tech:

Making bubbles inside a bubble:

Materials you will need:

• A straw
• A plastic dish or container
• 150mls worth of:

• Sugar, detergent and water

Instructions:

1. Pour the sugar, detergent and water into the plastic dish.
2. Dip the tip of your hand (fingers) into the liquid mixture and spread onto a table.
3. With the straw, dip inside mixture and blow a semi circle shaped bubble onto the table.
4. Dip the straw again into the mixture to create another smaller bubble inside the other solution (blow from top of bubble to last from evaporating).

Science at Tech!

It was the first day of tech in Term 2. As we had arrived at Pakuranga Intermediate I was shocked yet excited at the same time that the year 8’s were participating in science.

I partnered up with Cheska. Launoa and Philomena positioned themselves beside us. Our task today was to measure 100mls of cold water into a  beaker then to add some detergent. We had been given a straw for each pair to blow to formulate bubbles and observe. As I blew with all my strength, the bubbles evaporated amongst the beaker and over flowed almost touching the tip of the table.  Moving onwards after morning break, we received a magnifying glass to discover all the hidden facts behind blowing a bubble. I had leered to my right as Cheska investigated how to place a pencil into the extensive bubble. I was amazed, as I repeated the same process that Cheska had done.  It was an excellent and exciting learning opportunity.
