Dean Maureen MacDonald celebrated her birthday last month by being an honorary volunteer with Let’s Talk Science. Maureen helped Psychology, Neuroscience & Behavior graduate student Portia Kalun and Arts & Science undergraduate student Meena Alnajar deliver a workshop to Grade 2 students at RA Riddell Elementary on Hamilton Mountain. The class learned about wheels and axels, levers and inclined planes by building miniature playgrounds. More than 200 McMaster students deliver free workshops to over 15,000 elementary and secondary school students throughout the Golden Horseshoe each year. McMaster was among the first universities to partner with Let’s Talk Science, a national non-profit focused on education and skills development for Canadian children and youth through science, technology, engineering, and mathematics-based programs.
