Yesterday we were getting ready for our project on Monday. Our teacher showed us the sauntering iron and some examples of what we are going to be creating ourselves. We also went over some rules about how to handle the materials. Our teacher let us pass around some materials to look at them and feel them. During this unit of electricity, we will be creating our own electric circuit using tinfoil, popsicle sticks, cardboard and some other materials. We will be making 3 types of ways to make and electric circuit.
Today we were doing more on electricity. We finally got to do hands on little projects on making a circuit. We worked with a simulator trying to light up a lightbulb and it worked!! Mr Calvert, had us go around a table and he showed us how to light the lightbulb. He let us try it and this is how it turned out after a few try’s and working with my partner, Xiyan:
Today in technology class we were learning about our galaxy and atoms. Atoms make up our world and everything else. When we look up in the sky, the stars we see are only the stars in our galaxy, The Milky-way. We learned that a ray of light will travel 6 billion miles in one year. Our galaxy is 120,000 light years across. It is already 1000 light years thick. We have 400,000,000,000 stars in our galaxy. There are close to 100,000,000,000 galaxies. When you look very closely in the sky, you’ll see little discs, which look like stars, that are actually galaxies.
Atoms are the most smallest piece of matter. It is not invisible, but in order to see one, you have to look with a microscope. We only know 118 different atoms, which is in the periodic table.
We are learning about electricity and how power and energy works. Thales of Miletus discovered that rubbing amber would attract lightweight objects like feathers. The word for amber in Greek is “elektron”. Democritus believed that the nature of things was made of small, invisible particles of varying sizes called “Atomos”. That word then got changed into the word “Atoms”. We also listened to the Periodic Table song. We got to see all of the 118 elements that make up our planet and us. Our teacher taught us that Queen Elizabeth’s doctor discovered that the Earth’s core was molting. William Gilbert said “The electric effluvia differ from much air, and as air is the earth’s effluvium, so electric bodies have their own distinctive effluvia.” So from there on he was said to have made the word effluvia.
Today is the 4th day of technology class in school. I really am enjoying it, even though we didn’t start the projects yet. Yesterday my teacher set up a little scavenger hunt which involves working together. It was a bit challenging but with some hints and teammates, we found the answers to the puzzles.
We also started learning the safety rules while working with the tools in class. In class, the main important thing is to wear safety goggles. That is because when we are using the soldering iron, and some other tools, we have to be careful with the way we handle them. We could possibly hit our eye and damage it.
So far I am really looking forward to starting some of the projects because we will be working with tools and materials that I haven’t worked with ever.
