In technology class, we learned about a scientist named Sir William Gilbert. He was Queen Elizabeth the First’s docter and lived in the 1600’s. He invented the word electricity and made many cool experiments.
Today in class we learned about one experiment that he did. In involved a closed jar with some tinfoil inside of it and a wire connected that tinfoil to a rod sticking out of the jar. It also involved a stick and a some wool.
First, you rubbed the stick and the wool together really fast. After a while, if you had rubbed the stick and the wool together for long enough, you would put the stick near the rod sticking out of the jar. Then, the tinfoil inside of the jar would move!
Apparently, Gilbert tried to explain why this had happened for years. My teacher explained it in a matter of minutes. When rubbed with fur, amber gains a resinous electricity. However, when glass is rubbed with silk, this lets glass gain a vitreous electricity. Electricity repels the same kind and attracts the opposite kind of electricity. Scientists thought that the friction actually created the electricity. They did not realize that an equal amount of opposite electricity remained on the fur or silk. Dr. William Gilbert, realized that a force was created, when a piece of amber was rubbed with wool and attracted light objects.
This was a very cool experiment in class and I hope to do more like this soon!
So today during technology, we learned about atoms. Adams make up everything in the world, from cars, to TVs, to the new IPhone that everyone’s going crazy over. Atoms are so tiny that you can’t see them with the naked eye. The average atom is about one-tenth of a billionth of a meter across. But there isn’t just one type of atom, there are multiple. 118 have been discovered. These are called elements and can be found on the Periodic Table. Each element contains a different amount of protons. For example, all hydrogen atoms have 1 proton while all carbon atoms have 6 protons.
There are three parts to an atom. These three parts are protons, which have positive electrical charge, and are found together with neutrons, which have no electrical charge, in the nucleus of each atom. Negatively charged electrons orbit the nucleus.
Fun Fact: The word atom comes from the Greek word for ‘uncuttable’ or ‘undivided.’ For a very long time, people believed atoms were the fundamental “uncuttable” unit of matter.
Below I posted a video we watched in class. It will give more information about atoms.
Here’s a cheesy joke about atoms that I found on the internet
Tech class just started this week and it’s been really fun! Recently, we did a really fun breakout and learned a little bit about what we were going to do this year. But in this post, I’m not going to talk about what we have been doing here. Instead, I’ll be telling everyone what I hope to do in technology.
In technology, we’re going to learn how to find unique solutions to questions. According to Mr. Calvert, the first step in finding a solution is identifying a problem. That’s usually easy since problems are everywhere. After this step, you put yourself in the people who are facing the problem’s shoes. This helps you make a relevant solution to the problem and it also helps you understand the problem more. Once step is completed, brainstorm ideas to solve the problem. These ideas that you come up with can be very realistic or they can be moon shot ideas. Moon shot ideas are ones that are a little far fetched, but can still be accomplished. An example of a moon shot idea in history is when John F. Kennedy announced that Americans could go to the moon. After this, decide which ideas you will use and come up with a way to make them work.
I am excited for this in technology because I think that finding solutions to problems is a very important skill in life. Once you are able to do this, you can do just about anything because you have the tools to find a solution. That is why finding solutions to problems is something that I am really excited about for tech class and I really hope that we start doing this soon.
Hi guys! It’s been a while since I’ve posted. Anyway, now I’m in Sixth Grade Technology. I just started the class in the beginning of last week and it’s been really fun! A few days a ago, we did this really cool breakout.
Apparently, the custodians locked the keys to the safety glasses box in one of the breakout cases and we had to get them out. We had a certain amount of time to do this. In addition to the three locks that we had to open, there was also a separate tiny box that wasn’t necessary but could make our lives easier. The class split up into two teams to solve the breakout. Luckily, each team had a different box in which the key might be in, so we didn’t get in each others’ ways.
The first clue was a piece of paper that showed a story about a kid who broke a bunch of technology rules. We were also given a sheet showing which number these rules were. Using this sheet, we counted the rules that were broken and used their numbers to open the lock.
For the second lock, we found a sheet of paper that had some good rules and bad rules. The good rules made a path and we used this path to get to safety. The directions that this path took were the answer for the second lock. We got the right combination immediately but my team didn’t pull the lock properly so we took a while to open the lock.
Right before we opened the final lock, my friend came up to the team and said that she had opened the box with the hint inside of it. The team that I was in crowded around my friend and took out the hint. It said to go to the sign that said ‘Safety always comes first.‘ In addition, there was a flashlight inside the box. We shined the flashlight at the sign and saw that there was marker written over the sign. This writing was only visible if you flashed the light on it. The word safety was boxed with the marker. Seeing this, we realized that the last lock, a word lock, was using the word ‘safety’ as its password.
We opened the lock and found that the key had been placed in our box! Even though the other team had opened their box first, we had both opened it in less than the time given, so technically, both teams won.
This activity taught us how to work together and showed us that you have to listen to everyone’s ideas. Even though it was hard, it was a great start to the tech class!
