These are some of the simple machines we got to build so far:
This week, as you see, we had the last chance to finish our small simple machines and collect enough credits to move on to the compound machine. The Evil Elves were working on levers but now went on to gears, and The Cookie monsters are currently working on gears.
Ms. D also told us that once we are done with our blog post that we can write our reflection post right away. Here are some things that you should include in your reflection post:
*How do you feel you have improved as a blogger over the past year or two?
*How do you feel blogs contribute to learning for a class in school?*What else do you think a blog could be used for?
*How has blogging helped your overall writing?
*How has blogging helped your commenting to others about their writing?
*What is the most important thing you have learned from blogging?
**** Don't forget to label your post with your name, Reflection Post, 4th Quarter!****
For our other homework assignments i put a link to moodle at the bottom of my post.. I also found a bunch of videos from eureka. There is a video for the screw and the wheel, the inclined plane, the lever, the pulley.
The Inclined Plane -http://www.youtube.com/watch?v=pG_kT565-XQ&feature=BFa&list=PL356D58984641EDC6&index=1
The Lever -
The Screw and Wheel - http://www.youtube.com/watch?v=C-UXry7OiXM&feature=BFa&list=PL356D58984641EDC6&index=4
The Pulley -
These videos will explain all types of simple machines. There are actually seven types of simple machines, they are the screw, pulley, inclined plane, wheel and axle, lever, gear, and wedges.
Although this week we did not do much in class except for build with knex, we got to have a lot of fun with it. And even though they are called simple machines they can become very complex. like this model of a ferris wheel built from knex:
Even though this ferris wheel looks very complicated it is actually made of two or more simple machines. From just looking at the picture i can already spot one... a wheel and axle that go through the middle of the ferris wheel. So now you know that no matter how complicated a machine may look, it is always made of one or more of the seven simple machines.
The next scribe is... Drum roll... David!!!!
Moodle -
sorry about the colors, they didn't turn out right :(
ReplyDeleteHey Karin,
ReplyDeleteThis was an OK post and I think you could've done better. You probably should have put your name and the date of classes in your title. Also, your post didn't really have an ending, and the next scribe wasn't there either. The pictures were good, but you should've put one from in class on your post to show us doing K'NEX. Finally, there were several spelling and grammar mistakes. You should fix them as soon as possible. For good, you had a lot of links that related to simple machines. I liked how the pictures showed people who haven't seen K'NEX what kind of stuff we built. Your labels look good, and lastly, it was good how you gave the run down on K'NEX so far (e.g. who's ahead and the needed credits). Other viewers will probably find that interesting.
Good post, but you could have made it better.

Hi Karin,
ReplyDeleteThis is much better than what you have done before! You had LOTS of links, you had great pictures, your labels are correct, and you included almost everything you needed. Like always, you could have changed some things, for example including the date in your title. I like that you spotted the wheel and axle in the Ferris wheel, but I think you could have explained more about what it is doing to get the wheel to spin. You also said "inclimb plane" in a lot of places in the post, although I think that its real name is "inclined plane". Other than that, your pictures are captioned, you have a link, to Moodle, and in general your post is really good! :)
Karin – your post seems like it is a rough draft and you need to fix grammar/spelling errors, choose a different layout, subtitles, hyperlinks, date of the science class, and write about the real-life examples of what we did in class. It's good you added reminders about simple machines and photos, but you'd have to give more links and videos about K'NEX to add more ideas to your post and what else can be built from it. Although it's a nice post with different colorful body paragraphs, and I'm sure next time you'll make it even better.
ReplyDeleteDave :-D
Karin - nice work on this post, but in the future, please be sure to post on time. The title did not have a date, you have not given a real life relationship for this topic (which is a new requirement), your grammar is off in places and you as the writer, have not really explained the science of simple machines and why we were doing this project. I think you could have had more vocabulary explaining the different machines we were focused on this week - gears and levers especially. Plus, you could have discussed what kinds of questions teams needed to answer - mechanical advantage, how these machines improve work amounts, different parts of the machines, etc. BUT, your links and pictures are excellent and very helpful. They all work and provide scientific explanations. This aspect is definitely where you have excelled in this post - well done! Your labels look great too. Next time be sure to review the rubric to be sure you meet all requirements of the overall assignment. Nice improvement on media. ~Ms. D.
