10 tips I wish I knew when I first started teaching way back in 2003 or even sooner!
Having a blog can be like standing in a packed street corner with a megaphone. You can be as loud as you want to be, but usually…
If your wondering what to write in your new blog, check this article out. It has some great hints. The author gives some great ideas to keep in mind when writing a blog.
So the title is a bit deceiving. When I say the story continues the story continues for a couple of reasons the Mars rover, we are still troubleshooting and calibrating the wheels on the Rover. But the good thing is we are very close to finally getting it to drive.
Meanwhile, we finally had our Google Hangout with Michael Cox from JPL. It was a great talk, Mr. Cox first introduced us to all the missions going on at the center. I never realized how many missions they were or are involved with. But Mr. Cox pointed out that JPL does all Robotic and unmanned missions. I didn’t realize this. Some of the best missions have come from JPL. If you think about it Viking, Voyager 1 & 2, Mars Pathfinder, Cassini, Spirit, Opportunity and Curiosity are all the missions that have come from JPL. Amazing! His talk was great because it showed the students all that JPL had done and what it offered.
The final discussion was about the Rover, he met the team and discussed how the Rover came about. The Rover team showed him all that they had done and talked about some of the difficulties they faced. It turned out to be a great meeting. I did suggest to him that maybe we could get all the high schools building the Rover together on a skype. Then trade different ideas. He thought that was great and would look into it.
One thing I believe is happening, students are getting a bit frustrated because of the calibration section. They are trying to get the motors and encoders calibrated, their efforts sometimes cause other problems or they find other problems. It’s a frustrating part of the whole build but a great problem solving moment. Actually I even think a great learning moment for them, not everything can go right in real life and this is just a example. I know it is frustrating to them and can be discouraging, they want the Rover to drive! But it’s a learning process that continues with this project.
Happy New Year! Another year done and now we head into the last leg of the school year. A lot will be happening in the next couple of the months. After thinking about all that is going on, I think I’ll be just a bit busy.
First, we are rolling out our Mars Rover this month. Hopefully we will name it this month, then we will bring it to NC Museum of Natural Science for Astronomy Weekend. It’s going to be a great weekend for all, the Rover Team and Robotics Team will be running the exhibit. A combination of robots and Mars map will make our exhibit one to remember. (By the way Astronomy Weekend is January 26th and 27th at the NC Museum of Natural Science in Raleigh).
Next our Robotics team is going be competing in their first Qualifier, so the next couple of weeks will be hectic with getting the Robot ready. By the way the challenge is called Rover Rukus and fits in well with our Rover. Check out the challenge at the First Tech website.
And of course, there is the daily classes to prepare for. I think I sometimes make more work for myself. I’ve discussed this with my colleagues. Instead of going with the lesson I always must change it. But my classes aren’t the same every year. And I’m always looking to improve to the lessons. Isn’t that what teaching being about also?
But of course, I also have to get involved in other things, like the Blogging Challenge sent out by A.J. Juliani, I tried to do this once before it started out great then went downhill. So, I’m trying it again. With all that’s going on I figure this year I can do this! Anyway, one of the benefits is that I get to read some great blogs by people. And one of them is my colleagues who started blogging for the new year. Check out her blog. She’s a great Physics teacher and has some awesome things happening in class.
By the way if you are interested in naming the Rover, check out twitter @rippie77 with the Hastag #GibbonsMarsRover. And so the year begins!
Using satellite images A picture is worth a thousand words. Most journalists will agree that this still holds true, and therefore satellite images can be
Great discussion on how to read satellite images. If you use them in class this could be helpful resource when teaching about Satellite images.
So our build started about two months ago. Right now we work 2 days a week with maybe a couple hours on saturday. Like I said before 3 students are leading the charge on this project. But the help various Robotics mentors have been giving has been amazing too. So this entry will talk about the parts and mechanical assembly. Next blog entry will talk about the wiring issues, which I have to say have been challenging but one young man has done an awesome job with it. (Meihir you rock!)
To find all the parts you need for this Rover Project you need to go to the GitHub file area. There you’ll find parts list for different retailers. If you are lucky like our team, our head Robotics Coach/Mentor put a whole list together. He not only put the parts in order, but he also made up a shopping list, where to go and how much each part would cost. If you would like to contact me about that list please feel free, I can see if he will give me permission to share it.
Once we established that we had all the parts, we then had manufacture some of the parts. We are very lucky to have milling machine that was donated to us for cutting various parts. We used this to cut our side plates and base plates. It worked great! Any type of Lexan parts that we needed we used a Shopbot to cut. Our Lead Coach has a Shopbot he has allowed the school to borrow.

After working on the body parts, we started the wheels. Since the Hubs of the wheels did not have holes we had to cut them. Caution here after drilling the holes we found some of them didn’t line up correctly. Not a surprise, so we only used the holes that matched up (https://github.com/nasa-jpl/open-source-rover/blob/master/Mechanical/Wheel%20Assembly/Wheel%20Assembly%20Build%20Doc.pdf ). Drill press would be a big help here. Lucky enough there were at least three holes in each wheel that worked. Also make sure the kids or Adults are putting the clamps on correctly. We had some put the screws in wrong way on the clamps hubs and put the clamps hubs on incorrectly. Not a big deal since we caught it, but might have caused a problem down the road.
Once we got the wheels on we started to work on Rocker-Bogie section. This is the section that holds the wheels to the body. When building the Rocker-Bogie be careful with the instructions they are bit confusing. According to our lead builders they need to be improved/clarified on how plates and bars are fitted together. Directions weren’t specific on whether each side is mirrored or the same. Also, you need to cut one of the aluminum channels, we used a milling machine, but obviously not everyone has this type of equipment. This is where a machine shop would be a big help. If you have one near you I would suggest you create a partnership with them, so they can help you.

Our next section to work on was the Differential Pivot together. This was the part of the Rover that helps keep it from tipping over. It’s a big part of the suspension system. This is simplified, there is a lot more to it, great Physics lesson here. When putting together this part there was a section that we had to change just a bit, make sure you add more washers in between the aluminum bars and turnbuckle. We found it a bit unstable and adding the extra washers made a difference.
Once you start to build the Rover you come to find out there are small changes you can make to help make it work better. That’s what this blog post is about. These are the mechanical changes we made and tried to improve the build. There are other minor changes we made, but I only concentrated on the most important ones. One final note, the build I think was easy, it’s the wiring and programing that will take longer. If you are thinking of doing this project contact me and I can share more information about the build.
In this blog post I’m going to talk about a “mission” we are in the process of completing. We are building drum roll please…the Mars Rover, yep you heard me. An open source build developed by @JPL (Jet Propulsion Laboratory Open Source Rover) I came across the build one day when I received a newsletter from NASA and it had a bit of a blurb about a Mars Rover. I went to the website and find out about it. It looked interesting and a great learning opportunity. I thought this might be something that we could do here at school. Since I’m involved with the robotics team, it seemed this could be a good fit. So, I emailed our Mentor, Head Coach and Biggest Supporter. You name it, he’s an all-around total support and leader of the robotics team. I e-mailed him the website and information. I’m not kidding within next 24 hours he sent me an email telling me it was possible with a list of all the parts and cost. Amazing right, well he was as excited as I was to do this.
I gathered all the information needed and decided to approach our Principal. I stated my case by promoting the “mission” as a great community opportunity especially once the Rover was built. It could really be used to bring in tons of other people and the Rover could be used for other club’s activities. While being a great teaching tool. He thought it was a good idea. And after a long talk with him he funded our project. We are planning on a ton of things to do. Once our Principal gave us the go, we started to order the parts and had a meeting. The Rover team right now consists of students from Physics club (@physics_cghsnc ), Gibbons Robotics (@robotics_cghsnc) and Space Explorers Club (@spaceexp_cghsnc). The group mainly has students from the Physics Club. Two members come to mind Peter and Mihir. Both have done an outstanding job working on this project. I can’t begin to tell you how much their leadership is appreciated.
So, this began our project two months ago. Check out the pictures from the beginning. It all started with having to inventory all the parts. The whole Rover has about 400 parts, if not more. Once that was finished we needed to manufacturer some parts. This is where our maker room came in handy.
For now, I’ll end here, because I could go on forever. The excitement around the Rover is building and hopefully we will have a fully functional Mars Rover by Thanksgiving. I’ll keep up with the posts. My next one will go over the good and bad we have faced since the beginning.
Startling new research finds large buildup of heat in the oceans, suggesting a faster rate of global warming
More than 90 percent of global warming ends up in the oceans.
When a single platform lets you share and deliver materials, access student work, and allow students to work together, you can do some pretty incredible things.
I’ve used OneNote in the past, but this year I really focused on taking notes, grading and using it as the main tool in class. I’ve integrated it with PowerSchool because of the help of Gibbons Technology. Couldn’t of done it without them (Actually Ms. Coe). The transition was a bit bumpy, but once you start to get the hang of it its amazing. Set up the assignment in OneNote, it integrates it into PowerSchool. So now the assignment is listed there, and all I have to do is grade it in OneNote. Once that is done I can submit it and it will post to PowerSchool. Nice little feature.
As Ms. Gonzalez mentions you can integrate this into google classroom also, there are a couple of LMS that OneNote works with. I like how the article shows the difference between Google Classroom and OneNote. But guess what? You can use both! OneNote can integrate into classroom and can become the portfolio you need.
I’ll probably start writing about OneNote soon, I’m in the process of working with Teams. It will be the first time I tried it, can’t wait to see how things go.
10 tips I wish I knew as a First Year Teacher | Authentic Teacher Audioblog Episode 18 — Authentic Teacher
Warm Gulf waters were the engine behind Hurricane Michael’s quick intensification.
With more and more hurricanes hitting the US this is a good introduction article for students. It could lead to a more in depth study on “why we are getting stronger hurricanes”.
