Heart Dissection

In Health Science we have been learning about the cardiovascular system. After studying the third and final component of the cardiovascular system---the heart, we dissected deer, buffalo, and beef hearts. Here are some pictures from our class.

Tragedy of the Goldfish...an overfishing simulation

Today in Science 10 we studied the fifth and final threat to biodiversity----Overharvesting! The students completed The Tragedy of the Goldfish activity. This activity had students go fishing using only a straw to catch the fish. Students only needed to catch two fish each round to feed their family, but most students found themselves catching as many as they could each round. It was so extreme that one group caught all of the fish out of their pond. Certainly a good example of what happens in the real world and why overharvesting is a threat to biodiversity. Here are some pictures of students fishing.

Science 10 in the News

Below is a link to the RealAgriculture webpage that has interviews from myself along with two Science 10 students who recently attended the recent Ag Career Expo in Regina. Super Cool!

A Threat to Biodiversity!

Today in Science 10 we continued on our journey of looking at the five biggest threats to Biodiversity. Having already studies habitat loss and invasive species, today we looked at the effects of pollution on biodiversity. To study this we played, Deadly Links, a game where grasshoppers ate corn (pipe cleaner pieces), shrews ate grasshoppers, and hawks ate shrews in a given amount of time. What students did not realize was that the white corn pieces were sprayed with a chemical that was then passed along the food chain becoming most concentrated in the higher level consumers. Here are some pictures of us in action.
