Best Science Apps for 3rd Grade

By third grade, students have developed some serious skills to examine the world around them, and their curiosity has grown to match. They now have the mental skills to do experiments and gather data in more formal ways, but they are still learning basic facts about the world that most adults take for granted. Their science classes are likely to include more hands-on activities, and they read and write well enough to learn from what other people have already done.

In short, it’s a perfect time for them to get serious about science. These apps will help in loads of different ways.
