Can You Design an Investigation to...

The "extensions" are hands-on activities which extend the investigation begun with the core project. These are smaller and less directed projects which are either suggested by students or chosen from possibilities presented here.
You have been working very hard. It may not be obvious, but you have learned a great deal. Let's take a moment to review those gains.

You should now be familiar with the terms which are used to describe electricity. You should understand the connection between voltage and current. You know how to solder and how to use a voltmeter. You should also be beginning to understand the function of electronic components like resistors and capacitors. In addition to acquiring greater knowledge, you have also created the fundamental tools required to study electricity more.

Now comes the really good part. You are going to design and conduct a short scientific investigation. Your teacher will probably need to set some limits. This is not uncommon. Every research laboratory has to live with limits. The trick is to make the most of the knowledge, the tools, and the time that you do have.
