Getting Ready for School

Howdy

Today I was getting ready for school next week and trying to set up my classroom to better use my iPad in the class and outside of the class.  I found one of my old worksheets took the image I used and made a short video using the Educreations App.  The topic was observation.  Then I went into Google sites and made a web page featuring the embedded video.  From there I went into YouTube and found a video that I will use to make a worksheet on observation.  I already have some test questions about plant growth and my vocabulary of control, constant, variable, independent variable, and dependent variable.  Now I am putting together a blog post to share with the world.

Molecular Expressions

Howdy

Revisited one of my favorite sites and saw a different applet.

My favorite java app for windows is at:

Molecular Expressions:  Secret Worlds the Universe Within

This is an applet that shows the power of ten by looking at the universe from a macro view (10²³) to the nano world (10^-16) a difference of dividing or multiplying by ten 39 times doesn't seem like much but it will take you from 100 attometers (the inside of a proton) to 10 million light years which makes our local galaxy cluster look small (Milky Way, Andromeda).

The different applet that I checked out deals with the color of light.  Most people understand that you can mix pigments to create new colors (yellow and blue mix to make green).  However, most people don't understand that if you mix red light, green light, and blue light you get white!  That's because light is about the different between what is absorbed and what is reflected (simple web page explanation).

The new applet is the following:

Molecular Expressions:  Primary Additive Colors 

Put it on manual for best results.

Molecular Expressions:  Primary Subtractive Colors 

Put on manual as well.

Molecular Expression:  Color Structure

 I have seen similar and wasn't wowed by it but goes well with the other two applets.

Since I am talking abut applets the best resource is PhET this is hosted at my alma mater the University of Colorado, at Boulder.

No links just google phet anytime you need a science app.  Then you can find what you need.
