Making Golden Rain - investigating solubilities

One of the reasons that I love teaching Chemistry is that you get to do so many awesome experiments.  Not only are they cool, but they provide a great hook for students as a means of introduction to a new topic.  The reaction between potassium iodide and lead nitrate is a great demonstration to introduce students to the idea of solubility.  They each start off as a colorless solution when dissolved in water, but when you mix them together you end  change.  This reaction also demonstrates a double replacement reaction.  The pricipitate of lead (III) iodide is insoluable in water, but when heated it become slightly soluable while allows that lead (III) iodide to dissociate and the solution turns colorless again.  Its a great reaction.

Below is a great image from Compound Chem that gives a vidual to the quick explaination I gave above.  This is a great site for any chemistry teacher to check out even if this demo doesn't fit it what you are doing.

Virtuali-Tee (Human Body Augmented Reality Tee)

How cool is this t-shirt? It's wearable augmented reality! You can view the circulatory, respiratory and digestive systems and even has a heart rate tracker to visualize your heart beat.

You'll need to download the app to your phone but then all you need to scan your shirt and tap to view the different layers of your body. It even works in selfie mode.

Take a look at the video below or use the demo page to check it our yourself.   The t-shirt itself is a little pricey, but it could make a fun gift.

Free Binder Labels for Science Lab and Lessons

Sometimes I feel that elementary teachers get all of the cute stuff and I want some of it for my classroom. :-)  I came across these editable binder labels from Kessler Science and I had to share them with you all.  You can get them for free from Teachers Pay Teachers.

Enjoy!
