My Take
I recommend this without hesitation. It requires a bit of set-up in the beginning (creating student accounts) and setting up a routine with your learners...but it is completely worth it. This makes science fun for all learners. Plus the data the teacher collects guides instruction so there is never a dull moment!
How I Use It
I used the paid application for my 3rd, 4th and 5th grade science classes. It is fantastic. Motivating, engaging and easily differentiated. Students explore, evaluate and collect data on a variety of topics.
