You will need to use dried split peas or lentils for this experiment. You should not cook them beforehand since cooking or freezing ruins the DNA. ...
In the chemistry experiments, the red cabbage is used to make a pH indicator. Red cabbage can be difficult to find internationally or during the winter, so if you are unable to purchase red cabbage, the link below has a detailed procedure for using other materials to make the same indicator. [Make Your Own Indicators...
The blue substance you noticed forming on one terminal is copper hydroxycarbonate. It forms from the copper in the battery and the carbonate in the baking soda that was left over. It is the same stuff that turns copper statues (like the Statue of Liberty) a blue-green color. The chemical reaction that occurs to make ...
Though we have nested _Exploring Creation with Health and Nutrition__ _within our science department, it is not to be considered a lab science. There are no experiments with lab reports. ...
You can find denatured alcohol at any hardware store that sells paint. It will be called “denatured alcohol,” “denatured ethanol,” or “denatured ethyl alcohol.” It does not need to be 100% alcohol; it can be 70% or more. Also, isopropyl alcohol, which is only 5% alcohol, is not the same and should not be used. You c...
The MircroChem experiments are noted in the text with an icon shown on the top of page vii of the textbook. Also on page 646 of the text, as part of the index, all of the page numbers are listed for the 14 MicroChem kit experiments referenced in the course. ...
Experiment 9.2 says that the two people should move 250 meters apart. This is over 2 1⁄2 football fields (273 yards), and most people do not have access to a straight piece of property that allows line of sight for that distance. This experiment can certainly be done over a shorter distance. The experimenters should ai...
For experiment 9.1, you can substitute lye, which is sodium hydroxide. You will also need lye for experiments 2.1, 10.3, and 13.1. You can find lye by performing a simple internet search for caustic soda, lye, or sodium hydroxide. You can also try this link: [What Is Caustic Soda and Where Can You Get It?][1] [1...
Certainly, the lab equipment is not what you will find in a classroom, but most homeschooling parents do not have the thousands of dollars it would take to obtain the proper glassware and chemicals. Even then, it would be illegal, as you cannot order the proper chemicals without an OSHA-approved storage facility and th...
Some students have trouble with this experiment. Some never get the temperature to stay constant at boiling, while others can’t get the temperature to stay level while the ice is melting. The most common problem is that students heat the beaker too quickly. If heat is supplied faster than your stirring can distribute i...
