Huge library of educational videos to help you learn.

Effects of osmotic pressure on plant and animal cells. This is simple chart the sums it up pretty nicely. I chose this one because it shows that movement of water via green arrows.

I used this clip in my lesson plan for semi-permeable membranes as "motivation" for sparking interest in the subject. The main question: What happens to your fingertips when you've had them under the water for too long? Why? This can lead into conversation at the molecular level (i.e. osmosis).

This animation is simple to follow and has a great short quiz at the end. It shows how osmosis is different than diffusion and explains the different osmotic concentrations.

I find the TPACK model to be a little confusing, mostly because it has so many differnt sub-components. from what I can gather, though, the TPACK model shows that technology must be used and integrated in authentic ways that enhance both pedagogy and curriculum.

One questioon I had was "how can I use this. What should I be learning right now?" Then I found this information from McCrory 2008:

Knowing where to use technology resides on two factors:

1. First educators should identify parts of the curriculum that are hard to teach and technology might overcome pedagogical or cognitive difficulties.

2. Identify topics in the curriculum for which technology is an essential element of the science being taught.

After reading this, I realized that science teacher may be at a great advantage here. Since science and technology go hand-in-hand, it would be natural to slip in some extra technology when discussing difficult topics in the classroom.

One thing I noticed from the model is that once the technology changes ( it is always changing!) then the pedagogy and content should also change. That means as science educators, we will have to be constantly balancing the three elements (technology, content, and pedegogy).

I think the STEM model we worked on earlier would help support TPACK. A strong coallition between these disciplines would help the TPACK model.

there is also a pdf version, but the diigolet will not highlight pdfs so I bookmarked the html page.

GREAT website for computer simulation of the inside of a typical cell, how mitochondria function,, and more! The Harvard team puts together great videos to show in class. I use these as a G.A. to show that although the 2D diagrams in the text book are static, in fact the cell is moving constantly. Great resource for the biology classroom.

Dyson is a unique company that has been on the cutting edge of innovation for years. First the vacuum, then the air multiplier, out of which came the hand dryer technology. Taking every-day items and applying modern technology to improve archaic designs has been Dyson's mission. A fairly successful one, I would say.

This site shows STEM in action! Showing kids that STEM disciplines are not foreign to each other, but rather that the combined effort of many fields culminates the scientific process is paramount to the success of the next generation. STEM subjects should not be approached as separate entities. They are intricately intertwined with each other for the advancement of knowledge. The project shown in this video is an awesome example of STEM subjects coming together.

I am a big fan of the Wiley Online Library. Research articles are so important (and fun). I used this article as a platform for building my own spectrophotometer for under $100 (science fair project with my step-son). You would think that it would not be very effective in the classroom, but after analyzing gelatin solutions and plotting the data using Excel we got an r^2 value around .988, which is pretty good in my book.
