The Earth’s Materials module taps into student knowledge immediately by beginning with a story about a class rock collection. Students use a dichotomous Key to sort materials into natural and manmade and sort further using the adjectives rough and smooth; this activity builds both science and language skills as students classify materials and build deeper understanding of new vocabulary.
Our planet is ancient and fascinating. The Earth unit allows students to learn and think about our changing Earth. Online and offline activities allow students to study both the slow change of life on Earth over millions of years and the sudden change of extreme storms, earthquakes or volcanoes. As they learn, students create a base of concepts and vocabulary to build upon as they grow.
