I made a very a video in Alice 3. I am bad at it. I learned how to make characters move, turn black, become bigger, and disappear. I have, however, gotten into some problems. I could not make two codes run at the same time. I asked my classmate how to run to codes at the same time, but they don’t know. I have turned to Mr. Robert for a solution, but he doesn’t know, so I guess nobody knows. But it was fun making this.
I made a conversation in Alice 3, where a bear called White because it is white and Subject 1 talking to each other. This made me learn the basics of Alice 3 coding bricks, like how to rotate things and how to make them say stuff. I learned from the teacher that Alice 3 uses Java as the coding system. I also learned how to download Alice 3 faster by click the file the teacher gave instead of the link to the download website.
The objective the teacher gave us was to make the cheapest bridge possible. When I started, I didn’t really think of what my bridge would look like, so I made one that costs 500,000. That was too expensive of coarse, so I went on Google and searched up “bridge pics”. I saw multiple different interesting designs, and some suck. In all those designs I decided to use a suspension bridge design. Using my brain of the size of a peanut, I made the layout.
And then made it better a little bit.
Unfortunately the Ugly Ahh Bridge failed. I forgot save the picture for the fail of the Ugly Ahh Bridge. The structure couldn’t handle the compression and tensions, and it was over 350 thousand so I just moved on to another design. The next design was an arch in the bottom, and i thought it would cost a bit less.
It was pretty cheap compared to the Ugly Ahh Bridge.
It was too unstable to be tested, and I figured that it would take an big amount of time and money to perfect it. So I decided to put the idea at bay and switch to something more easier and simple. I came up with multiple ideas and just played around with them, trying to find one that I could use.
I ran different designs and then one caught my eye, because the test was successful. I decided to use a arch bridge design because of the test, also beacause Teacher Robert said Romans made arches that were good.
I came up with this design, and ran a test.
So the two bars couldn’t take the compression, I changed them into hollow tubes made of 200x 200 Tempered Steel, thinking it would work. Then, I tested it. It went pretty well as expected.
It was good, but after seeeing the price, I knew I could do better. So I thought of an idea to shrink the budget, here is how it kinda goes: Bigger = higher price (mostly), so long length = higher price, which also means short length = lower price. Following the idea, I shrinked the bridge height so that it would cost less. At last, insteaded of a arch bridge, I ended up with this design.
It was ok, so I did some tests and ran into problems.
The test showed that the two supporting bars had too much compression.
I changed the supporting bars to 200x 200 hollow Tempered Steel tubes.
Then I ran the test agian.
Apparently, it didnt work, still too much compression. I put two more supporting hollow tubes and ran the test.
It was a successful test. But one problem, I checked the price and…
Nah!
That is not good at all. Its only 20 thousand cheaper, and I want it to be under 300 thousand. So I guess it’s time for a new design.
So I basically just took out some stuff and made the whole thing on hollow tibe so it would be cheap. So I ran tests and all hollow tubes just didn’t work. It was way to wiggly so I named it “Soppy Bridge”. I changed some tubes that have tensions into bars and changed the thickness and material. And I ran the last test.
The final test was a success. So I checked the price…
Hooray!
It was finally under 300 thousand and lower than I expected.
I thought this was fine so I finally stopped.
Conclusion:
Making bridges was fun but hard. I learned that hollow tubes handle conpression well, solid bars handle tension well, and arches handle more weight than triangles. 10/10, would recommend doing this.
The Special Air Service or SAS is a special forces unit part of the British Army, they were first founded as a regiment, the British government thought there were no use and it was disbanded after WW2, but later it was decided that the British army needed a commando unit, so the SAS was reestablished.
The SAS was used in many ways, including: counter-terrorism, hostage rescue, direct action, and covert reconnaissance. One of the most famous things they have did is the rescue of two hostages during the Iranian Embassy Siege.
I have learned how to use different features in Google to help me search for what I want faster in google search, and I am going to share them with you.
The Google search feature, “filetype”, is used to find a specific type of file, It is really helpful when I need to find, for example: If I want to find a image of the tank, M1 Abrams that is a file type of pdf, what I would do, first, go to google search, search: filetype:pdf M1 Abrams, and get results.
“Site” is a feature to use when you want a sites from a certain group, for example: I wanted a site about bees from the government, and not from anyone else, what I could do is search: site:gov bees in google, and get the results.
Another feature in Google is “OR”, this is not a typo, OR like or, is to help you search for different types of files or sites in the same search, for example: I wanted a site about computers from the government or for education in the same search, I should type: computers site:gov OR site:edu, and get the results.
” “are a great feature in Google to use when you want to find a song, story, maybe a poem, but you dont remember the name of the poem your searching for, for example: I want to lisen to a song, but I only know the lyrics, which is: “I’m gonna ride till I can’t no more”, I can go search up: “I’m gonna ride till I can’t no more”
Intext is a feature to find websites that have the words you want, one time, I wanted a website that has the word, gorilla inside of it, but i didnt know how, but thaks to the computer science class, I now know, so what I could search is: intext: gorilla.
-is used when you want to cancel out unwanted info, when I wanted to search for cars but I dont want cars from the 1983’s, then i could search: cars -1983.
My conclusionis that these thing Iearned really helpped me a lot in Googe searching.
On the first video-Did you know? I learned that India’s population is so big that 25% of the population is bigger than USA’s total population and there are 845 million monthly active users on Facebook, and 1 in 8 couples married in the US in 2011 met online, now I know more things about the world and the internet of the world that might be useful someday.
On the second video-Matt Cutts explaining how Google search works, I learned that Google uses “Spiders” to get your search results, these “Spiders” also get ads that might be helpful or relating to waht you searched for, and they also use something called “PageRank” to help you get more better search results, and I will use these information to search better keywords on Google to get better results.
