Prevention of Destructive Burning or Oxidation
We have seen that oxidation is very valuable in giving us usable energy. Can you name examples of oxidation or burning which are harmful? From what we have learned about burning, we should be able to suggest means by which destructive oxidation may be prevented.
What two conditions are [...]
Bacterial Immunity Science Project
Microorganisms can do many things beside causing foods to decay.Some do very valuable work; so valuable in fact, that without their aid life would cease to exist upon the earth.Qn the other hand, some, such as the disease- producing (pathogenic) forms, are extremely harmful, causing the premature death of many persons.

Conducting Reference Toxicity Tests with Lettuce Seeds
The idea behind a reference toxicity test is that the test organism, in this case lettuce seeds, will respond in a predictable manner to varying concentrations of a particular chemical compound. At some threshold concentration, all of the test organisms will be killed (or in this case, none of [...]
