Illustrated Guide to Home Biology Experiments: All Lab, No Lecture (DIY Science)
Format: PDF / Kindle (mobi) / ePub
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 (ck-12.org).
- 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 (thehomescientist.com/biology), 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.
observe Aspergillus. (Like Penicillium, Aspergillus sp. is ubiquitous, and is likely to be represented among the colonies growing on your bread specimen.) Figure 30-9 is a 100X overview of a Penicillium prepared slide. Figure 30-10 shows the conidiophores and conidia at 1,000X. Figure 30-11 is a 100X overview of an Aspergillus prepared slide. Note the similarities between Figure 30-9 and Figure 30-11. Figure 30-9. Penicillium sp. wm showing conidiophores, 100X Figure 30-10.
the metamorphosis of the larvae in both containers and note any differences based on competition for resources. For the first week, observe the containers daily at the same time each day. Note any changes in appearance of the larvae and count the number of larvae that are undergoing or have undergone a visible change. Beginning with the second week, you can change your observations and counts to every other day. Continue these observations until the first larvae begin to emerge as pupae, shown

Disaccharides, also called compound sugars, comprise two bound monosaccharides, which may be the same or different. For example, the disaccharide lactose contains glucose bound to galactose, sucrose contains glucose bound to fructose, and maltose contains two bound glucose molecules. Disaccharides can be hydrolyzed (split) into their component monosaccharides using enzymes, heat, or an acid or base catalyst. For example, sucrose can be hydrolyzed into its component monosaccharides, glucose and
