It has been quite a while since I last made a blog post! The majority of the posts on this site are from the Creative Technology XR Studio Course that I took last fall. This spring I am taking a Creative Technology Seminar course with Professor Richard Jochum and Columbia University's Teachers College.
Last week Professor Sheinkopf visited our class and taught us about electromagnetism along with some other very interesting lessons. I have made a short video of a project I made in reaction to what we learned. My goal was to recreate the demonstration of electromagnetism that was presented for us in class and add something new to further my learning. I created an electromagnet using a screw, a wire, and batteries. I went through a few different iterations of this changing the type of screw and the thickness of the wire. Instead of using one battery I ended up using four1.5 V batteries that I put inside my brother's old rocket launcher. The rocket launcher had a button which allowed me to disconnect and connect the current from my electromagnet, turning it on and off. I also bent a small nail and attached a paper clip with a little flag which made it easy to see the magnetism of the electromagnet.
Here is a video of me presenting my electromagnet:
This week we also learned that the formula for Watts is Volts times Amps. Here are a few devices I have at home that all need to be plugged into the wall in order to work. I have used this formula to find the missing information.
For the hair dryer I knew the voltage and current but needed to calculate the wattage.
HAIR DRYER 125V multiplied by 15A = 1,875W
For the lamp and the bulb I knew the voltage and wattage but I needed to calculate the current (Amps).
LAMP 660W divided by 250V = 2.64A
BULB 60W divided by 120 V = .5A
In class we also spoke about the variety of codes that we all use on a daily basis. One example is the way we leave our flag up on the mailbox and the mailman knows to take the mail away. Another code is the zip code that you write on your address. QR codes have become increasingly popular even in museums! We also often use "code" when we text to shorten common phrases.
Here are two exercises that allow people to talk in code to relay information.
Exercise One: Guess the Animal
For each word follow this formula:
Hold up your hand and display the number of letters in the word you want to say. If there are more than ten letters hold up all of your fingers and then squeeze your fists together. Then hold up as many fingers as you need to display the remaining number of letters. Repeat this if the word has more than 20 letters. After the number of letters in the word has been established you will need to have the person you are communicating with guess the letters that make up the word. For each letter decide on an animal that whose name begins with that letter. As you might in a game of charades, act out the actions of this animal until the person with whom you are communicating guesses the letter. They may need a pen and paper. Continue doing this until you finish the word. Once each word is finished jump up and down.
Exercise Two: Color Coding
For each sentence follow this formula:
In your hands you hold 26 coloured cards. Each card represents a letter. Hold up a series of cards to spell out each word. When the word has been successfully communicated put the cards down on the table and begin your next word. Once you finish a sentence clap twice.
I made this graph in Canva to show you what each card might look like!
