Human Body, Health, and Nutrition



This article contains information on human body, health, and nutrition science projects. Keep reading to find human body, health, and nutrition science project ideas for 1st - 4th grade, 5th - 8th grade, and 9th - 12th grade students.

Science Projects: the Human Body, Health, and Nutrition

This group of science projects focuses on projects in the areas of the human body, health, and nutrition. Although Health may be treated as a separate subject in some curricula, the fact that the human body, nutrition, and medicine are included in science curricula gives us good reason to include them here. Of course, you can adapt them as you wish, not only curtailing them, extending them, adapting them to a different grade level, and modifying them to better suit your child, but also changing them to suit your curriculum. So if health is a separate subject in the schema you’re following, don’t worry - just shift this list into your health folder instead of your science folder.

1st, 2nd, 3rd, and 4th Grade

Tips: If you remind your students that you’re available to assist them as required to complete these science projects, it will help them avoid frustration and keep the focus on science. They may need your help for record-keeping, for learning to use simple tools, and for keeping track of on-going data collection. Students this age may particularly like science projects with an edible aspect.
