Project 3 – Option 1 – Student Assignment

Student Assignment

This Snell’s Law simulation tells us how a ray of light will behave as it (1) reflects off of a surface and (2) transmits

through a media with a different index of refraction. Using the Snell’s Law simulation on the website, play around

with the blue Incident Ray, and observe the (1) Reflected Ray and (2) Transmitted Ray.

Set N1 at 1 and N2 at the following settings: 1.5, 2.0, 4.0, and 5.0. What happens to the angle of reflection at

the index of refraction of N2 is increased? What happens to the angle of refraction as the incident ray passes into

N2?

Do the Assignment

If N1 is set at 1 and N2 is increased, the reflected ray will not change at all. It will continue to reflect at the same

angle. The refracted ray, however, will bend more towards the normal, or perpendicular, making the angle of

refraction smaller. If N1 is larger than N2, the refracted ray will bend away from the normal, or perpendicular,

making the angle of refraction larger. If N1 is too much larger than N2, then there will be no refracted ray, only a

reflected ray.

I felt like this application was one of the more helpful applications, especially because it helps teach something

that many students struggle with. It was good to get on the internet and search for things that I can incorporate

into my classroom (when I get one). I was unaware of the wealth of supplemental things online. Also, I had my

business-minded girlfriend do the exercise I typed up, and it made sense to her. So I feel like this is something

that could easily be used to help teach about the behavior of light rays.

Also, if you need to see the application for yourself and you want to download it yourself, there is a file called

lvrt.zip that you need to download and put in the same folder as this application in order to get the application

to work. I've got them both saved on my computer and wouldn't mind forwarding them to you or bringing my

computer in and showing them to you .. Thanks!

Proof of my video chat with Vicky, a friend from England

I really like these video chats because they let you connect with people that can be on the other side of the world. In my classroom, they can be utilized to connect with other classrooms in other cultures. They could also be used to have a guest speaker "come to your class" and give a lecture. And I am done with my video.

My Project 2

storyboard

I am currently in the brainstorming part of my video project, and I am struggling with how to make a supplemental video that will address that needs of a student in my content area without making it just a video of me teaching something. I am considering just doing it over rock types and explaining different properties of rocks and how they differ from one another. I've spent a lot of time on planes and in airports this last weekend, and that time was used to think about the project. However, I wasn't able to write anything down because I didn't have my school gear with me. I have probably been thinking about how to do this project for about 3 hours (3 hours that I have focused on thinking about this project).

This is my project #1 so far. I am without the second lesson because it includes that youtube video and the latest email says to hold off on stuff like that. I will add it as soon as we talk about it in class tomorrow. There is a very important survey to take, so make sure that you do that. This was actually quite fun to make and I think it can be very beneficial for students. Also, I made a month's worth of activity for August 2010. Picture me rollin'!

websites

I feel like websites would be useful in the following ways. First of all, class information (sylabii, schedules, supplemental material, contact info, etc.) could all be posted on the website for student use. These would be extremely useful to the forgetful student. Secondly, I feel like it could be something you could post fun widgets on that relate to your content material. For example, there are loads of programs online that help with circuit building that would be very helpful for many students. Websites obviously wouldn't be much use to students that don't have access to the internet, but there are many public places where internet use is free, such as the library, so this is less of a problem.
