Kids discover 缅北强奸 through 25th annual Bring Our Children to Work Day

Children in Grades 4 to 7 saw demonstrations such as a superconducting, levitating train

Jason Harlow usually teaches his introduction to physics course with lectures on vector algebra, error analysis and Hooke's law.

But on Thursday, Harlow, an associate professor, teaching stream in the physics department, tweaked his lesson plan slightly for a younger audience. About 370 kids from Grades 4 to 7 came to the University of Toronto's downtown Toronto campus for the 25th annual , and many more visited 缅北强奸 Scarborough and 缅北强奸 Mississauga. 

On a tour of the physics department, Harlow showed two dozen girls and boys and a few parents how a superconducting, levitating train can move around a track after it is cooled to 200 degrees below zero, using liquid nitrogen. The students oohed and aahed as they watched the train go round and round without touching the surface. 鈥淚t's a ghost train!鈥 one child said.

The class had no shortage of questions, and Harlow wasn't surprised by the enthusiasm. 

鈥淧hysics is the most basic science. It's very, very, very simply, 鈥榃hat is going on?鈥欌 he told 缅北强奸 News. 

鈥淎nd you don't need any special equipment 鈥 athough nitrogen definitely helps,鈥 he joked.

Earlier in the day, the whole group of visiting youngsters learned about how the ear registers sound from Barbara (Dee) Ballyk, an associate professor, teaching stream and the faculty lead in the Faculty of Medicine for the MD program. 

Some of the more squeamish kids in the auditorium yelled 鈥淓w!鈥 at the sight of videos of a beating eardrum and moving voice boxes.

After showing the kids slides of healthy and damaged auditory hair cells, Ballyk warned them to listen to music at medium volume and to wear earplugs at concerts to prevent hearing loss.

After her lecture, the students split off for tours of departments 鈥 everything from medicine to archeology 鈥 and of other important spots at the university, such as campus police and Hart House.

Over at 缅北强奸 Scarborough, told a class about her career as a gymnast representing Canada.

Meanwhile, at 缅北强奸 Mississauga, kids visiting a physics lab (below) learned first-hand about force and momentum while passing a basketball around on a spinning see-saw.

Downtown, the students who opted to visit the chemistry labs got to see a soda geyser, made of Mentos and cola, spray 12 feet above the courtyard near Lash Miller Chemical Laboratories. 

Afterward they made paintings using safe acids and bases on a canvas dyed with red cabbage water, which contains the pH indicator anthocyanin. 鈥淭his is to show them that chemistry is all around them,鈥 said Patricia Meindl, the chemistry librarian who organized the tour. 

Katherine Burton (below, right) is an undergraduate majoring in chemistry and molecular biology. As a lab tech for the demonstration, she explained why the paper changed colour. 鈥淚 think children are all really intelligent, and if you tell them it's just a change in what the compound's background is, and how it changes aromaticity, they actually understand more than you'd think,鈥 she said.
