Do you waste water?

Just a reminder Grade 10's that you need to collect data on your family's water usage any two days over the Christmas holidays. We will use this data to complete the "Do you waste water?" LAB when we return to school in the new year. Enjoy this next week of holidays. See you back on Monday January 6th,2014!

A Perfect Flower

Today in Biology 20 we dissected a perfect flower....not perfect in that it looked beautiful and smelled delicious, but perfect in that it was a flower that contained both male and female reproductive organs. We spent time identifying, drawing and labeling all four whorls of flower parts and tomorrow will look at the pollen grains using a light compound microscope. You can see our work below.

Deadly Links!

Today in Science 10 we began investigating how other "things" besides energy flow through an ecosystem. To learn about biomagnification, we became a new organism---a grasshopper, a shrew, or a hawk, and simulated a food chain. The grasshoppers fed on the corn fields (pipe cleaner pieces), the shrews fed on the grasshoppers, and the hawks fed on the shrews. Unknowingly the white pipe cleaner pieces were sprayed with a pesticide. The pesticide moved through the food chain becoming concentrated in the top consumer. Here are some pictures of our Deadly Links Game.

Another Dissection

Today in Biology 20 we dissected the sea star. Check out our pictures below.

Bio 20 dissects the Crayfish

Today in Biology 20, we dissected the crayfish. The crayfish was our representative member of Phylum Arthropoda. Characterized by its hard exoskeleton, jointed appendages, and segmented abdomen, we got to examine both internal and external anatomy for this amazing animal which so many of us (well, not Ms Roach) enjoy eating.

Race Day in Science 10!

Thursday November 7th was race day in Science 10. We raced our homemade balloon cars to see which of them would travel a minimum of 3 meters and in the fastest time. We had a great deal of success with the top car in Period 1 (created by Chase and Jace) travelling 7.75 m in the fastest time. In Period 5, the top car (created by CJ, Jenner, and Wade) traveled 8m to cross the finish line in first place. Excellent creativity and effort grade 10's! Be sure to check our the pictures and video from period 1.

First Dissection....DONE!!!

Way to go Biology 20 students! Today we dissected our first organism---the EARTHWORM! Equipped with safety goggles and gloves (well at least one each), we examined both internal and external anatomy.
