Robert Bruce Thompson has written several fantastic books about science experiments that you can do at home. They are incredibly detailed, and I would highly recommend them to anyone interested in Chemistry or Biology.
The PDFs of his books are available at the following websites:
- “Illustrated Guide to Home Biology Experiments”: http://www.thehomescientist.com/manuals/Illustrated_Guide_to_Home_Biology_Experiments.pdf
- “Illustrated Guide to Home Forensics Experiments”: http://www.pdfdrive.net/illustrated-guide-to-home-forensic-science-experiments-e5917255.html
- “Illustrated Guide to Home Chemistry Experiments”: http://www.pdfdrive.net/illustrated-guide-to-home-chemistry-experiments-e18837377.html
A bundle of all three books can be bought from Amazon for approximately $69.06US, or about $23US each. Failing that, ask your local library to buy a copy.
Another interesting book is “The Golden Book of Chemistry Experiments“, which contains many experiments that children could do in the 1960s. Many of the chemicals or experimental designs used in it are now known to be unsafe, so do your research well.
