Saturday October 16 – A Trip to Titan

Did you know that Titan, Saturn’s largest moon, is one of the most Earth-like celestial bodies discovered? With a thick atmosphere and lakes of methane, the surface of Titan looks eerily similar to Earth. In this session, we will build a model of the Huygens probe, which was landed on Titan. Learn about exploring celestial objects, conditions for a habitable celestial body, and the upcoming 2025 Dragonfly mission to Titan.

Preparation: two (2) tart foil tins or tin foil, a cup, string, a plastic bag, ruler, marker, scissors, glue or tape, hexagon template (please print two copies of this page, cut along the lines to create hexagon halves, and tape together to create a full hexagon)

Expert: Jahnavi Shah is a PhD student in Geophysics and Planetary Science at the University of Western Ontario.

Saturday October 2 – Leaf Chromatography

Can you be-leaf that it’s fall already? As the seasons change, so do leaf colours. But have you ever wondered where the colours come from and why leaves change colour in the fall? In this session, we will reveal the colours of fall leaves using a chromatography technique. Learn about leaf pigments, photosynthesis, and how leaves know when to change colours. 

Preparation: green leaves from three (3) different plants, nail polish remover or rubbing alcohol (any percentage works), three (3) tall cups (that will hold the nail polish remover or rubbing alcohol), paper towels or coffee filters (white in colour if possible), scissors, tape, three (3) sticks (popsicles, chopsticks, or twigs)

Expert: Dr. Gerry Gourlay has a PhD in forest and tree biology from the University of Victoria and is a volunteer coordinator of CAGIS Victoria.

Saturday September 25 – Papermaking at Home

Did you know that paper was invented over 2000 years ago, and most Canadians use 308 kilograms of paper per year? In this session, we will be making our own handmade paper from recycled scraps. Gather your scrap paper and learn about environmental sustainability and the chemistry of paper manufacturing.

Preparation: blender with adult supervision, scrap paper, water, paper towels or rags, a large plate or surface to work on. Optional: pantyhose and a wire coat hanger, a large plastic tub, things to add to the paper (dried flowers and leaves, coloured paper)
