Freaky Science Show

On 5 May, about 120 learners in Grade 3, 4 and 5 attended the exciting Freaky Science Show in our own hall.  Professor Freaky and mischievous Debbie demonstrated basic science concepts.  First they explained words like "science", "theory" and "experiment" in a fun way.  Then they performed several spectacular experiments.  Learners learnt what substances, fluids and gases are.  The best part was to see what happens if you mix them together!  Everyone will remember that water and oil are immisscible (don't mix) and that oil is lighter than water.  The lava lamp experiment showed that sugar makes the oil heavy enough to go down to the bottom of the bottle, but as soon as the sugar dissolves in the water, the blob of oil will bob up to the surface again.  It is very difficult to mix maizena and water and make it into a ball, called a colloid.  If you pour vinegar onto bicarbonate of soda, your volcanoe will erupt with fizzy bubbles. It was proved that this process produces air (a gas), when balloons on bottles with  vinegar and bicarbs inflated.  The learners remained captivated and enthusiastic throughout the show.  Each learner received a brochure with instructions and explanations of cool experiments that can be done at home.

Bubbling volcano: I'm no fool, Science is cool! Oil and water: Even with dancing, jumping and shaking - No lasting friend-making! Possible or impossible? Colourful, undrinkable and immiscible! Freaky and Debz Made us guess, What's the sticky stuff; That was tricky and tough! Hard or soft, wet or dry? This gooy gluey colloid Makes me wonder: WHAT and WHY?? Something sour inside, Some white powder on top. When they collide, Will the balloon pop? "Can it be?";  "Look at that!";  "Is this real?";  Scary cat! Pick me, pick me!
