I am still trying to get caught up with the photos that I took at Science Rendezvous last weekend.  There was so much happening!  Lots of people were involved and engaged in the various activities that were available both at Yonge Dundas Square and on St. George street.

below: On the stage at Yonge Dundas square:  Start with three identical piles of building blocks and three teams, put ten minutes on the clock and see what towers result.   The challenge was to
build the strongest, tallest, or most awesome tower.

below: How do you test the strength of a tower?
By giving one exuberant girl a big orange ball of course!

below: At the end of the competition, all three teams came together to build the tallest tower that they could.  It didn’t quite reach the stage roof, but it was close!

… more great activities…..

below: Question: How long does it take the light from the Sun to travel to the Earth?
Answer: sunlight travels at the speed of light (rounded to 300,000 km/s) and it has to cover a distance of 150 million km on average to reach Earth.  With a bit of math, the answer is 500 seconds, or 8 minutes and 18 seconds.

A sign stands in the street with information about the sun on it. Behind it is a second sign, this time with information about Mercury. Behind that are people at Science Rendezvous on St. George street

A group of students is sitting on a sidewalk. One of them has a laptop and he is controlling a robot machine with wheels that is moving around on the street.

below: How unique are you? Test yourself for various phenotypes (the product of your genes)… Can you curl your tongue? Can you smell freesias? Is your thumb bent?  From answers to these and five other questions you can determine if you are 1/10 (you share similarities to many people) or 1/1000 (you are more unique)… or something in between.  Apparently I’m 1/45 and if you’re curious, my thumb is straight, I can’t curl my tongue and I can smell freesias.

Two students are conducting a genetic phenotype test on a couple of volunteers. They are looking to see if they can smell fresias or taste coriander.

below: A demonstration using acids, bases, and pH indicators.  Technically, pH is a measure of the concentration of hydrogen ions.  In practice, it indicates how acidic or basic a substance is.  Water, with a pH of 7 is neutral.  Acids have a pH less than 7 while bases have a pH greater than 7.  A pH indicator is a chemical that changes colour depending on the pH.

below: How much energy is a gummi bear? Find out by heating a little bit of of potassium chlorate in a test tube.  Once it is liquid, add a gummi bear.  Smoke and flames ensue.  When the potassium chlorate is heated, it produces oxygen gas which ignites if there is combustible material, such as sugar, available.

A student is doing a chemistry experiment to show how much energy is in gummi bear candy. He has lit one on fire and burned it to show the release of energy. It was done in a test tube.

Two young kids have been dressed up as mad scientists and their father is taking their picture. They had rubber gloves on, eye protection and a lab coat. They both have pipettes.

A woman and a girl are racing objects that they made. Inside small rectangular boxes are marbles that make the boxes tumble down an incline.

 

below: Corn starch and water makes a wonderful substance.  It’s not liquid and it’s not solid.  If you are fast enough you run on top of it but if you stop moving, you sink into it!

A boy is running barefoot along a course that is filled with corn starch and water. Onlookers are cheering him on.
