Mr. Russell’s 3rd Class were on a voyage of discovery all week, with science experiments every day for Science Week 2020!

The boys used vinegar and baking soda to inflate a balloon by tying the balloon (filled with baking soda) to the top of the bottle and allowing the soda to drop into the vinegar, which released carbon dioxide, which then inflated the balloon. It was great fun!

They also used a balloon tied to the top of a sports bottle cap which was glued to a CD, and released the bottle top leading to the CD hovering just above the ground and moving across the floor.

The class made lava lamps using water, vegetable oil, food colouring and an effervescent vitamin tablet. The end results were pretty cool!

The boys also experimented with eggs, with one sitting in water while the other egg sat in vinegar. Over the course of 5 days, the egg in vinegar saw the shell completely eaten away while the shell on the egg in water stayed solid. The boys learned that vinegar is an acid and that acid erodes, or melts, the egg shell.

For another experiment, using hot water, they also saw how food colouring and sugar in Skittles contain different chemicals and so the colours don’t mix, leading to a lovely burst of colour on the plate.

The class also were learning about how scientists search for life in the solar system by searching for microbes. The boys tested different surfaces using bread and sealed them into zip lock bags.
