Are You Into It?Biological and Chemical Sciences graphic

Are you fascinated by how living systems work and the chemistry in the world around us? It is all about biological and chemical sciences in this project. Whether you want to learn about life and the chemistry of your world in agriculture, medicine, biotechnology, genetics, crime scene investigation, or engineering, you can discover the secrets through this project.

  • Develop an interest, knowledge, and skills related to biological and chemical sciences
  • Develop problem solving and logical reasoning skills
  • Improve communication and teamwork skills by working the way scientists and engineers do – in teams
  • Develop responsible attitudes about science and how science relates to our everyday world and people’s lives
  • Gain experience in problem solving and decision making using science process skills

Here’s what you can do all year!

Starting Out Basic / Level 1

  • Discover what chemistry and biology are all about, from plant and animal science to medical to chemical engineering
  • Learn how to control parasites in your animal
  • Learn about biosecurity systems in the U.S.
  • Discover how chemistry is used to solve crimes

Learning More Intermediate / Level 2

  • Have fun with chemistry and biology! Do experiments, learn about safely, discover the cool things technologies make possible.
  • Learn about diseases and environmental controls
  • Learn about garden fertilizer and nutrients plants need to grow

Expanding Horizons Advanced / Level 3

  • Design your own experiment and enter your results in science and technology fairs
  • Learn about DNA and genetics
  • Learn about breeding and reproduction techniques

Project Hot Sheet

Fair Exhibit Tip Sheets

Tip sheets are used by judges to evaluate your exhibit. Use them to help make the best presentation of your work. Choose a tip sheet based on your project's intended purpose.

If your project:

Exhibitor Fair Information Form (Word or editable pdf)

Exhibit Evaluation Form (B/W pdf)

Other Opportunities to Explore:

  • Attend Iowa 4-H Youth Conference and participate in workshops, motivational speakers and a community service project, bringing ideas back to your community.
  • Is it county fair time? Consider taking an exhibit, a piece of your project learning to the fair for judging and to show off what you’ve learned throughout the year. It might get selected to go to the Iowa State Fair.
  • Enter your science experiment or engineering design in the a local science fair or the State Science + Technology Fair of Iowa
  • Contact your local ISU Extension Office for other local workshops, activities, and events.
  • Meet others interested in biological and chemical sciences. Check out camps at the Iowa 4-H Center.
  • Interested in a college education in the area of biological or chemical science or engineering? Schedule a visit with Iowa State University to explore those majors.

Step It Up

Pass it on! Now that you know how, share it with others. Here are ideas to get you started.


  • Enter a science & technology fair
  • Create an exhibit for your county fair or do an educational presentation


  • Complete a Service-Learning project

  • Present information about hand washing and germs to a local daycare class
  • Organize an event to using activities from the Forensic Biotechnology Guide (see More Resources) to teach to teach younger children how biology and chemistry are used in crime scene investigation


  • Organize a field trip to a local lab, business, or industry to learn how science, engineering, and technology inform what they do
  • Attend 4-H youth conference
