Here's a quick update on what we've been doing in science over the last couple of weeks. Recently we've been learning about rocks, so we became rock detectives for a day and investigated the many different types of rocks in the environment. We examined them closely and tested whether or not they are permeable. We also learned all about chemical reactions and made our very own lava lamps using just water, vegetable oil, food colouring and alka-seltzer tablets.
While we were learning about breathing and respiration, we created our very own model of the lungs using balloons, straws, plastic bags and bottles. The plastic bag acted as the diaphragm, and when we pulled it down the balloons filled with air, demonstrating exactly what happens in our lung when we breathe. Pretty cool!
