Science Week in Ms. Costigan's 6th Class

14th Nov 2025
We rolled up our sleeves, got hands on and had loads of fun exploring science in action this week.
We made our own oobleck. That oozy, gooey mix of cornstarch and water that acts like a solid when you press it and a liquid when you relax. The girls loved testing how it behaved, squashing it, poking it and watching it flow. 
The balloon and vinegar experiment, we uncovered a classic chemical reaction. As the vinegar met baking soda, the balloon filled up with gas and blew us away!
