Year 5 (Grade 5) · Science · Activity · $3.99 USD
A complete Earth Day science investigation for Grade 5. Students ask 'Which materials break down (decompose) in soil?', make predictions, plan a fair test with clear variables, and record observations over 6 weeks in a results table. A set of example class results lets students analyze data and draw a conclusion even before their own test is finished. A second part is a home water-use survey with a data table. Includes a teacher page with safety notes, setup steps and a full answer key.
