Science rules in Laurie Henshaw’s Grade 4/5 Class

By David F. Rooney

The students in Laurie Henshaw’s Grade 4/5 class at Mountain View School showed off their scientific expertise Wednesday with an interesting and entertaining science fair.

Here are some of the kids and their great experiements:

Sarah Carey talks about how she used food dyes to help white carnations change colour. While she says, "Hmmm," when asked if she likes science. Sarah was excited by this project. David F. Rooney photo
William MacDonald got a real kick out of using warm and cold water to inflate and deflate balloons. How do you do that? Well, warm water causes the air inside a bottle capped with a balloon to expand, thereby inflating the balloon. Plunging the bottle into a pail filled with ice water causes the air to contract, thereby deflating the balloon. David F. Rooney photo
Simi Luttrell used vinegar to turn both raw and hard-boiled eggs into very rubbery and bouncy objects. David F. Rooney photo
Jonah Prunkle lowers a container filled with warm food dye into a container full of water. The temperature difference causes the food dye to boil out, much like a submarine volcano. David F. Rooney photo
Soleil Kelly demonstrates how you can use lemon juice to write invisible messages that can only be revealed using heat. David F. Rooney photo


Sydney Frick demonstrates how her home-made slime can be made viscous using Borax. David F. Rooney photo
Jake Leeder demonstrates how a battery can be used to heat wires of different thicknesses to generate heat that could be measured using a thermometer. David F. Rooney photo
Do soft drinks rot your teeth? "Yes!" says Halle Wolgram. She says they'll also dissolve pennies. David F. Rooney photo
Rider McCallum used an industrial lamp to simmulate the sun for an innovative solar oven. It took him 6:48 minutes to melt chocolate at 45° Celsius. David F. Rooney photo
How do you make an egg float? Carmen Sampson demonstrated how with her experiment. David F. Rooney photo
Jessica McIntosh created a tornado in a bottle. David F. Rooney photo
Justin Carter created liquid layers of oil, corn syrup and coloured water, then dropped different objects in to see if they would float. David F. Rooney photo
Jenna Bollefer used sands, gravel and charcoal to see what might a good job of cleaning dirty water. David F. Rooney photo
John Sidjack uses heat inside a bottle to make an egg get sucked inside. David F. Rooney photo
Ben MacDonald demonstrates how you can weigh air to a rapt audience. David F. Rooney photo
Simon Blackie created an electromagnet that could attract nails and other objects containing iron or steel. David F. Rooney photo


Young Callum Gribbon used the sound from an organ to mix corn starch and water in his Corn Starch Monster experiment. David F. Rooney photo
Jenna Knight wanted to show how she could use static electricity to "bend" flowing water. David F. Rooney photo
Kobe Brunetti used a few spuds to generate enough electricity to light up an LED light. David F. Rooney photo
Alexandra Robertson is fascinated by astronomy and would love to be an astronaut. David F. Rooney photo
Barrie Ballantyne used a piece of cardboard bearing different images on each side to generate an optical illusion: two images shown at the same time. David F. Rooney photo
