Clinical Trials

When trying to find a cure for Pellagra, Golberger performed what was to be referred to as a 'clinical trial'. Today clinical trials are used to test new medicines and procedures.  To further understand clinical trials, click on the image and follow the tutorial.
If you want some extra credit, then create a blog post explaining all about clinical trials. Be creative with your post.  Try to go beyond just using text.  Maybe use an xtranormal cartoon or something like that.  In addition to explaining a clinical trial, talk about protocol, placebos, and consent. Either on the form below - or in your journal - define each term.

Studying People Scientifically

From Saving Fred to All Aboard, approaching problems involves well thought out methods.

What if you're studying people instead of solving a problem like we did in class today?  Does the problem solving method change?  Do you need to think about what's ethical with human testing? What's right and wrong? Next class we will be looking into one doctor's attempt at solving a serious health problem which existed in the Southern United States in the 1900s.  Watch the video (click on Dr. Goldberger's picture) and think about these questions:
1.  What was the problem of pellagra?
2.  What did people think caused pellegra?
3.   What evidence did Dr. Goldberger observe or collect about pellegra?
4.  What did Dr. Goldberger conclude about the cause of pellegra?
5.  What are your thoughts about the right and the wrong in Dr. Goldberger's testing to solve this problem?

Density of Liquids and Solids

We've completed a number of labs on density of solids and liquids. For more practice- pick from two optional pieces of homework. You don't have to do both to get the 'bucks'. Just pick one that suits your fancy.

Kitchen Layers- follow the guidelines on this sheet but instead of drawing a picture and explaining - make a blog post with a photo or video and include an explanation - immiscible, interface, density etc.

Gizmo - click on the interactive density picture in this post and it will take to you to gizmos. Log in and go to the density lab we played with in class. Fill out this sheet as
you manipulate the shapes and find their volume, mass, and density.
