Light+and+Sound


 * Central Idea:** What is the big idea?

[|gDoc Vocabulary List]

__**Tuning In**__ We started this unit by brainstorming what we know about Light and Sound. Then, each group made a Top Ten Facts list. Here they are:

__** Light **__ 1. If you change the direction of the light, then the shadow will change 2. Without light we can't live 3. Light reflects off shiny things for example diamonds 4. Light produces energy for things 5. Light takes times to travel 6. Light travels in waves 7. Closer you are to the light hotter it is 8. You can make a light with electricity 9. Stars shine in the darkness 10. Light can burn because its a thermal energy

__** Sound **__ 1. There are different kinds of sound and they make music 2. Sound has different tones. 3. Sound is invisible 4. Echo is sound that bounces 5. There are sound, voice that older people over twenty years old can't hear 6. Without air, we can't hear sounds 7. Sound is slower than light 8. Most of the time, larger objects are noisier than smaller objects 9. People and animals can recognize sound, because they have heard what had made a sound before 10. Sound can spread out far

__**Puzzles and Mysteries and Dialectical Thinking (2 thought experiments) **__

Next, we looked at two famous thought experiments.



We tried to answer these questions using the [|dialectical thinking] (thinking of both possibilities at the same time and not making a decision about with one is right). To do this, we developed a theory to answer //yes// and //no// to each possibility. Here are our posters:



__**Finding Out **__ We started the researching process by asking questions. Everybody asked questions that they found interesting, and then we sorted the questions into four categories; // How does it affect the world? // // How do we use it? // // How does it work? // // What does it do? //



We then talked a little bit about research, and the many ways that we can do it. We made a googledoc with the pros and cons of various different research methodologies. [|The Many Ways to Research]

Then, we choose a research question and a methodology and got working on our question!



We researched our questions and made a joint google presentation to answer them:



After we wrote our book, we decided that we needed a lot more information. Over the next two weeks, we went through a ton of different experiments!
 * Learning Centers and Experiments**

Here is an overview of the experiments:



Here is our analysis of the experiments:

 * Animations**

__**What if.... Art Project**__

We watched a video about a boy who can see sound waves (he uses echolocation to live, like dolphins or bats). Then, we asked some interesting questions and used those questions to make some visual art....

[|What if each person saw the world in different colors?] [|What would the world look like in 2D?] [|What if sound waves traveled backwards?] [|What if the world looked like Crayon?]
