Let's Talk Science - Lavalamps

 

Lava Lamps 

 
On Thursday, April 25, 2019, the Grade 7 students participated in an exciting hands-on workshop presented by Talveen from Ryerson University's Let's Talk Science. The students conducted experiments and created their very own lava lamps using household ingredients such as oil, water, food-colouring and Alka Seltzer tablets. They learned about heterogenous mixtures, hydrophilic and hydrophobic properties and scientific concepts as they apply to simple items such as lava lamps. More importantly, they applied the scientific method, altered the control groups to test out various hypotheses and reported back on their observations.  What a fun afternoon where the young scientists-in-the-making messed with matter on a molecular level!!
