Don’t eat or drink while doing experiments, and never taste substances being used (unless instructed to do so). Avoid touching chemicals. When doing these experiments, use only nonmercury thermometers, such as those filled with alcohol. The liquid in some thermometers is mercury. It is dangerous to breathe mercury vapor. If you have mercury thermometers, ask an adult to take them to a local mercury thermometer exchange location. When using a microscope, always use indirect lighting when illuminating objects.
Designing a new medication for heart disease, studying the spread of an invasive plant species such as purple loosestrife, and finding evidence that there was once water on Mars all require different methods. Despite the differences, however, all scientists use a similar general approach to do experiments. It is called the scientific method. In most experiments, some or all of the following steps are used: making an observation, formulating a question, making a hypothesis (an answer to the question) and a prediction (an if-then statement), designing and conducting an experiment, analyzing results and drawing conclusions about your prediction, and accepting or rejecting the hypothesis.
Can you detect the motion of any gliding joints with your fingers? Science Fair Project Ideas What is the origin of the terms atlas and axis for the first two cervical vertebrae? A person’s weight while standing can squeeze joints together, particularly the vertebral joints. Could such squeezing change a person’s height during the course of a day? Design and carry out an experiment to find out. Often, when you bend your knees, raise your arm, or crack your knuckles, you hear a snapping sound. What causes such a sound?
