Mining for Chocolate Chips

Last week we "mined" a chocolate chip using two different methods. First students removed the chocolate chips any way they wanted, including crushing the cookie. Then students used a toothpick to "mine" the chocolate chips. 

They discovered that while crushing the cookie resulted in extracting more chocolate chips, the cookie was destroyed beyond repair. Removing the chocolate chips with a toothpick kept their cookie in tact. We compared this with mining different minerals and learned that some methods destroy the environment while others protect it. It was a delicious lesson!

Field Trip to Telus Spark

On Monday we went to Telus Spark to learn more about boats as well as structures and buildings. Our first task was to determine which items float and which sink.

We thought light items will float but learned that it's objects with air in them that float the best.

Next, we designed a boat using found materials. Each group was assigned a specific type of boat such as, sailboat, barge, tugboat, cruise and cargo ships.

The last task was to test the boats to make sure they would float! We placed our boats in the large water table and watch them float downstream.

Thanks again to the parents who volunteered their time to come with us!
