Today in class we watched a spoken work video about bullying. It was really powerful and I found it to be so very sad... It surprised me how emotional I was watching it the second time. As a teacher, I see so many of my students looking so happy, that it was a sobering reminder to me of some of the real difficulties that kids (and adults) can be going through. It is a reminder to treat people with kindness and empathy. To look for beauty in everyone.
In Biology 12 we are learning about how your body functions and how your systems work, but there is so much more to being alive than what we touch on in a science course that seems so definite & about facts in black and white.
Feel free to comment or blog about your thoughts on the video.

Biological Molecules
We will be watching this video on Biological Molecules in class - it's actually really funny:)
And also educational.

Biological Molecules & Food Lab
On Friday we completed a lab testing different food samples for the presence of lipids, starch and simple sugars. You can post your observation pictures and results chart(s) to your blog and then work on the following lab questions to post as well.
1. Describe a positive result for each of the tests that you performed in the lab.
2. Starch molecules are large carbohydrate polymers. Find and post an image of the molecular structure of starch. What are the building blocks that starch molecules are made of?
3. Thomas and Josh had interesting results to their simple sugar test - if you are following either of their blogs, look at their picture of their test tubes after they took them out of the hot water bath.
After 2 minutes, only 2 of the test tubes were yellow/orange, and the rest remained blue. They took the two positive test tubes out of the hot water bath and left the others in the hot water bath for 2 more minutes. At the end of the two extra minutes all the test tubes indicated a positive result. Based on your knowledge of carbohydrate molecules, why do you think they got these results?
4. Making connections - Describe the passage of one of your food items through the digestive system, starting with the mouth & ending at the anus. Include the specific enzymes, accessory organ secretions & internal conditions the food/chyme would pass through from start to finish.

Digestion/Food Lab
Today we will be working in the lab with food sample to determine which types of biological molecules are present - we will be doing 3 different tests; testing for lipid molecules, testing for monosaccharides (simple sugars) and testing for starch (large carbohydrate molecules).
For each test, I want you to use the iPads or your phones to take pictures of your observations & results and post them to your blog, as well as complete your lab questions and publish them - each student should have their own post for questions on their own blogs.
Let's see how this works!

Digestive System Video
We will be watching this video to explain the function of the Digestive System today...
Enjoy!
Enjoy!
Digestive system tshirts!
Yes, it is upside down. But because of peristalsis, this digestive system could still work!

Water
Last class we were learning about water - happy to see the excitement about water droplets on a penny and some blog posts with pictures already!
Here is a video I'd like you to watch and with a partner create a blog post about whether you think this could be real? Why or why not? Relate our lab activity from last class with what we have learned about the properties of water so far.
