How do scientists find out about things? In fact, how do they decide what things to find out about? As you work your way through this page, you will assume the role of a high-energy physicist (a scientist who studies subatomic particles, not one who eats too many Twinkies !) interested in learning more about neutrinos. You will discover a process that you can use later to find out more about other things you are interested in. Along the way, links, hints, and examples have been provided to help you, but be sure to think for yourself as well: next time, you'll be on your own!
You will need a research notebook. A composition book is best, but a spiral notebook is ok. Be sure it has pockets for storing articles, computer disks, and a copy of your final report (plastic pockets which adhere to the inside cover are available at office supply stores). Don't forget to label the front with your name and the title of your investigation.
1As this page is being created, at 2:15 pm on July 27, 2004, a Google search for the word “neutrino” produced 846,000 results. In your notebook, give at least three reasons why this might be a problem.

2One way to narrow the focus of your investigation is to create a question that addresses an area of the topic about which you are particularly interested. Another way is to state a claim about the topic. When scientists do this, the statement is called a “hypothesis.” In your notebok, discuss possible advantages and disadvatages of each approach.

3How do you decide what aspect of the topic interests you, in order to create a question or hypothesis? The first step is to identify what you already know. In your notebook, discuss some of the things you know (or think you know) about neutrinos.
Want an example of what could happen if you don't do this?
Chances are, you still need more information in order to decide how to narrow the topic. Here are some links which will tell you about neutrinos:
4A strange thing happens when we learn about a topic: when we know more, we have more questions than we did when we knew less! In your notebook, state a question that you still have about neutrinos, and turn it into a hypothesis.

5You can test your hypothesis through investigation. Some possible ways are:
|
Look it up. |
Example Hypothesis: A neutrino is a type of quark. |
|
Combine several sources. |
Example Hypothesis: Neutrinos were created in the Big Bang. |
|
Experiment. |
Example Hypothesis: Neutrinos cannot pass through lead (assuming you have access to a neutrino detector!). |
|
Use mathematical analysis. |
Example Hypothesis: Neutrinos are not affected by gravity. |
|
Survey experts. |
Example Hypothesis: Most scientists agree that neutrinos have mass. |
In your notebook, discuss how you will investigate your hypothesis. If you did not use one of the above methods, describe yours and tell why you think it is more appropriate.
6Now you're ready to close out this page and be a neutrino researcher! In your notebook, record the steps you take, the information you gather, and the conclusion(s) you reach. But before you leave, click here to celebrate!
