Today's class theme was 'Pause and Reflect'. We are just about to finish the first marking period and it is a good time to look back at how we have done.
We discussed a demonstration on air pressure. We inflated a balloon inside a soda bottle, then pressurized the bottle and watched what happened to the balloon. We also felt the side of the bottle and noticed that it became warmer when air was added, and became colder when the air was released.
We then reviewed our chapter two test, and then received graded chapter two homework and also our graded lab reports.
Finally, we are done with our sound and light books--please bring them back in for the next class.
