By the end of fourth grade, students will develop an understanding of personal health. Have students find the nutrition information on food labels to group foods according to the nutrients they contain. Have students remove the lids from the agar plates, touch the agar with their fingertips, and then close the plates and tape them securely. Place the plates in a warm spot in the classroom and monitor for bacterial growth. Students use a paper bag to test for the presence of fat in various foods.
Students then rank the foods according to the amount of fat each food has.
Students will complete Lab Manual pages 77-78 as they do the activity. Have groups of students explore safe and unsafe use of medicines. Students can cut pictures from magazines that show people using medicines.
