Decisions, Decisions...

This week I had a really hard time deciding on an article for you to read.  So, I decided to let you choose.  I will give you four links to different articles from Smithsonian.com.  You need to read the article and write a 4 to 5 sentence summary of what you read.  The choices are....

Human Skin Can Detect Odors, Some of Which May Help Trigger Healing

Why Does Very Hot Water Sometimes Feel Cold?

Scientists Have Basically No Idea How Many Cells Are in the Human Body

Five Reasons Why You Should Probably Stop Using Antibacterial Soap

If you find another article about cells, cell shape and function, mitochondrial disorders or any other topic that is relevant to what we are studying now.  Send me an email and I can add it to the list for this week.

Micro "Selfies"

For week two of our unit on Microscopes, Cells and Cell Transport, we are going to have a little contest.  Your challenge is to find the coolest electron microscope image and decide if it is from an scanning electron microscope or a transmission electron microscope.  Be sure to give the image URL and tell which type of microscope was used in taking the image.

Below is an image of a scanning electron microscope image of the head of a human flea taken by retired scientific photographer, Steve Gschmeisser.

Here is a transmission electron microscope image of a human liver cell taken by Dennis Kunkel.  He even offers electron microscope calendars...how cool is that.

I will keep track of the favorites.  Whoever posts the image first gets credit for finding the image and will get a vote for their image to win the prize.  Good luck.

Here is a link to the Cell LibGuide that Mrs. Nelson and I created.  It has some links to microscope images, but there are tons of cool images out there.  In order to get full credit, include the link, what the image is and if it is a SEM microscope picture or a TEM microscope picture.
