Fourth graders need to learn science related vocabulary. Understanding these glossary terms are paramount to kids as they help build foundational knowledge and understanding, not only in current grades but also in higher grades. One of the good ways to learn science words is to go through the word, it's definition, and have some contextual meaning. This is precisely what is available through this 4th grade glossary # 1 App.

Different kids have different styles of learning and remembering things. From our research, we have learnt that some kids look at pictures and science terms and relate to them, some kids would read the definitions and try to understand with pictures as a reference. In this app, we have included all of these methods of learning. We have used age appropriate explanation. Kids can choose to use any of these styles to learn science terms - goal being to get familiar and learn from this App.

Along with learning, there are practice modules for each of these sections to reinforce what they have learnt. The quiz section has been redesigned with interactivity and motivational messages to encourage kids.

This app is divided into the following 4 learning and 4 practice units.

+ Earth Science
