Assignment # 4

Finalized title and hypothesis in log.
The title - the title catches people’s attention and lets them know what your project is about, it should be short (10 words or less) and easy to read.
The hypothesis – now that you have developed a question to explore and conducted some background research you are ready to formulate a hypothesis. A hypothesis is an educated guess, a statement about how the scientist thinks the experiment will turn out. It is a prediction based on all the available information. The hypothesis will be your opinion deduced from the facts you researched. It should identify the subjects of the experiment (plants, mice) and state what is being measures (growth, weight), the conditions of the experiment (different-colored light sources, junk food versus regular food), and the results expected (light colors produce faster growth than dark colors; a nutritious diet produces higher weights than a junk food diet).
For example:

• Bean plants grown under dark-colored light will grow more slowly than bean plants grown under light-colored light because of a lack of sufficient ultra-violet light waves.


• Mice raised on a diet of junk food will show lower body weights after 6 weeks than mice raised on a regular diet because of a deficiency of necessary nutrients in the junk food.[1]

The hypothesis is very important, it will form the basis of your investigation.
