Experience the magic of biology in your own home lab. This hands-on introduction includes more than 30 educational (and fun) experiments that help you explore this fascinating field on your own. Perfect for middle- and high-school students and DIY enthusiasts, this full-color guide teaches you the basics of biology lab work and shows you how to set up a safe lab at home.

The Illustrated Guide to Home Biology Experiments is also written with the needs of homeschoolers firmly in mind, as well as adults who are eager to explore the science of nature as a life-long hobby. To get the most from the experiments, we recommend using this guide in conjunction with a standard biology text, such as the freely downloadable CK-12 Biology (

  • Master the use of the microscope, including sectioning and staining
  • Build and observe microcosms, soda-bottle worlds of pond life
  • Investigate the chemistry of life from simple acids, bases, and buffers to complex carbohydrates, proteins, lipids, enzymes, and DNA
  • Extract, isolate, and observe DNA
  • Explore photosynthesis, osmosis, nitrogen fixation, and other life processes
  • Investigate the cell cycle (mitosis and cytokinesis)
  • Observe populations and ecosystems, and perform air and water pollution tests
  • Investigate genetics and inheritance
  • Do hands-on microbiology, from simple culturing to micro-evolution of bacteria by forced selection
  • Gain hands-on lab experience to prepare for the AP Biology exam

Through their company, The Home Scientist, LLC (, the authors also offer inexpensive custom kits that provide specialized equipment and supplies you’ll need to complete the experiments. Add a microscope and some common household items and you’re good to go.

bubbles, and that the bleach solution can reach all parts of the vessels. Allow the vessels to soak in the bleach solution overnight, by which time everything except perhaps a few spores has been killed. We do not recommend reusing the plastic Petri dishes. Simply rinse them with tap water and diskard them with the household trash. The tubes can be washed with hot (if necessary, boiling) soapy water to clean them. Make sure to remove all traces of the agar gel, which can be persistent.

observing the cups over a period of two to three weeks, noting any differences between the two cups. After two to three weeks, gently remove one of the seedlings from each cup, making sure not to damage the visible part of the seedling or its root structure. Wash the seedlings gently with a trickle of tap water to remove any soil that is adhering. Use the magnifier (or a stereo microscope, if you have one) to observe the structures of the seedling. Note the size and appearance of the roots,

cooled to form a gel. (No, you can’t use gelatin for culturing; bacteria eat it and turn the gel into a runny mess.) Agar itself is merely an inert substrate. With the exception of a few marine bacteria, few microorganisms actually feed on agar. To provide food for the microorganisms, you add various nutrients to the agar mixture as you’re making it up. Food-grade agar is sold in supermarkets (often in the vegetarian section) for a few dollars an ounce. Culturing-grade agar is sold by lab

divides, separating its chromosomes into two identical sets and forming two separate nuclei from these chromosomes. Mitosis typically occupies about 10% of the cell cycle. During cytokinesis, the cell splits into two distinct daughter cells. The cycle then continues as these daughter cells individually enter interphase and continue to divide. Figure 19-1. Major events in the eukaryotic cell cycle NOTE Although cytokinesis is often thought of as the final step in the mitotic stage of the
