Students observe soil samples, talk about where soil nutrients come from, receive a letter from a company that wants to know if dead plants can be used as fertilizer, then develop research questions.


    Students will be able to: Understand that nutrients are the invisible building blocks that make up all living things, know that all living things need nutrients to grow and stay healthy, have ideas about where nutrients in soil come from, form a research question.


    For the class:

    For each group of 3-4 students:

    • small clear bag or container of poor soil, such as sand or clay
