My Take
I run a nano size after school program, two days a week for 9 year friends of my 9 year old daughter. We perused the videos and activities, jointly deciding on which activities to bring to our group. Although it purports use of household items, I did have to run to the store for diaper rash ointment and nail polish. We all reviewed the instructions prior to the activity, I helped with the first attempt and let them continue to make the experiment multiple times. They quickly wanted to move onto other nano studies.
How I Use It
I liked the simplicity of the directions. I love the engagement with the iPads' easy swipe to each set of instructions, accompanied with images. We read the summary of the nano science after the experiment. Later, the girls recalled facts about nano science with ease.
The project involving rainbow film led to artistic endeavors. The girls made iridescent bookmarks for friends. The girls then chose to engage with a the Nano sunblock activity completely independent of me. They stated a hypothesis aloud before checking results. I am impressed. I would use this in high school advisories- 20 min. blocks.
