For this exploration experiment you should find objects in your house that emit and/or detect a form of non-visible light (e.g. infrared, radio waves, microwaves, ultraviolet) and use these to determine how this light behave with respect to reflection, absorption, emission, etc. Some examples of objects that use non-visible light include: TV remote controls Garage door openers Radios Cell phones, tablets, and computers (these can use up to 3-different parts of the radio/microwave spectrum depending on whether they are using WiFi, Bluetooth, or cellular networks and each may behave differently). UV lights (such as "blacklights") Night vision scopes Note that sources that use high power, such as microwave ovens, are not safe for doing home experiments so you should avoid using these. Select one of these objects and make a hypothesis about what sorts of materials absorb and transmit (and if possible reflect) these types of light. Then conduct experiments to test your hypothesis. You can try any household materials that are convenient, such as paper, cardboard, plastics, glass, aluminum foil, etc. Remember that the behavior may depend not just on which materials you use but also their thickness. In addition, some wavelengths can bend around corners so it may need to design experiments to account for this. Note that the exploration experiment is a full experiment. You will need to collect data, make measurements, and analyze the results. In your writeup you will also have to describe the question (don't just copy the text above: say specifically which sources and materials you are working on), give a hypothesis of what you expect and why (what is the underlying cause of what you are seeing), describe in detail the steps you took to answer the question, list all of the data you used and any analysis you did, and finally, describe the conclusions you drew from the experiment. Note that you won't be marked down if your hypothesis turns out to be incorrect.
