Establish a classroom atmosphere that celebrates the sharing of learning. Have opportunity for students to practice new learnings. Make student learning available to the larger community, i.e. books students write are shared with other classes, students report in school paper, student work is displayed at school, etc.

Students swap and test each other's designs.

Objective: To share individual experimental designs.

Activity: Each student will swap her/his acorn experimental designs with a classmate who will verify the findings by following each other's experimental procedures.

Assessment: Quality of lab procedures designed especially by their adherence to the steps of the scientific process and the ability of other student's to get the same results.
