FREE science app – DIY Nano teaches kids (and their adults) about the nanoscale. Funded by the National Science Foundation and developed by Berkeley’s Lawrence Science Hall, this educational app provides a series of activities and videos about nanoscale science, engineering, and technology. There are 12 hands-on activities in this app. Each one starts with a summary which gives an overview of the activity, the time it will take to complete (prep – clean-up), and the suggested age group. Next, there is a materials list. All items are inexpensive and widely available. Then there is a series of step-by-step directions – with pictures. Finally, there is an explanation of “what’s going on” in the activity. Related videos are at the bottom of the page so that your child can learn more. This app is very well-organized, easy to use, and provides a wonderful introduction to the world of nanoscale science. The best part about the app is that it gives kids and adults the opportunity to learn something new together and how exciting is that?!?
