This activity allows students to investigate classification and create their own dichotomous key. Discussion will include classification of items in everyday life.
After watching a video, students classify soils using a ternary soil diagram and run online computer models to see how the proportion of sand, silt and clay affect drainage. Students then use the ternary soil diagram to predict how real soils (found from online soil maps) will behave in terms of runoff and infiltration.
This lesson helps grade 3 students understand the difference between Vertebrates and Invertebrates.
In this activity, students are provided with a list of supplies that survived their plane's crash in the Amazon jungle. They will organize the supplies to classify which items are useful for surviving in the Amazon. Students will use estimation and basic math skills to determine how much they can carry and to decide on what items to bring with them to survive in the Amazon until they reach their destination.
Students demonstrate their skill in soils investigation and interpretation through independent projects undertaken in groups of one to three and presented in class using visual aids.
