3d Printing Club

I have wanted to run a 3d printing club for middle schoolers for a while now (since I discovered BeetleBlocks).  I specifically wanted to have a 3d printing club where we focused on jewelry making in hopes of getting MS girls interested in STEM. I have a 3d printing business and sell my 3d printed jewelry on Etsy and at the Lebanon Farmer’s Market. I see many of my students at the market and know that 3d printing jewelry might be the hook to get more girls interested in 3d printing.

My earring design ready for sale – a shared project on BeetleBlocks

Yesterday my dream of having a 3d printing club became a reality at the Lebanon Public library and with the collaboration of two librarians. We were able to borrow two 3d printers from libraries around New Hampshire and schedule a couple of summer sessions.  We met a week prior to the first session, when we had the printers, to make sure we could run them and change the filaments, etc.  We have an Ultimaker 2 Go and a MakerBot Replicator.  This is a bit complicated as they take different size filaments and use different programs to prepare the models.  We have some jewelry findings and different color filaments – silver, gold, bronze in 1.75 mm for the MakerBot and blue in 3 mm for the Ultimaker.

We were hoping to get 3 printers and have 3 students per printer for a group of 9, but only 5 had signed up so we opted to go with just 2 printers as the third was at a library on the other side of the state.  When I got there on Monday, there were 9 students.  The librarians had decided to let the drop-in students stay and I was fine with that.

My notes for my intro to the 3d design & printing process.

After a brief introduction where I wanted to make sure that they understood 3d printing was an iterative process not unlike the engineering design process, I showed them a jar full of bad prints from my jewelry printing business.  Then we got started.

For the first of the two sessions, I introduced BeetleBlocks and we created simple rings by measuring and using a tube shape (Here’s my video tutorial). In just three lines of code, the rings were created and we were able to have them export and save to a flash drive/sd card.  We loaded half onto one printer and half onto the other and started printing them. Rings take about 5-9 minutes each.  The goal was to have something to take home by the end of the session. Then during the week they could drop in and print another, bigger, individual print like a pendant or a pair of earrings, etc.. The librarians had a list of times when they would be available during the week to help the students print another ring or a pendant.  I thought this would alleviate the problem of having enough class time to get everything printed.

I created a second video tutorial on how to code a pendant or earring from a squiggle. There wasn’t time to go over the whole tutorial during the session and anyway students were busy exploring BeetleBlocks: adding their names to the rings, looking at community projects, playing with extrusions and other shapes. While some just wanted to watch the printers for a while.

Next week we are going to explore TinkerCAD as another application that I know that makes it easy to create 3d designs.

LMS Winter Carnival

Last week I ran two coding sessions at the middle school for their Winter Carnival.  There are a wide variety of activities offered for the 5th- to 8th-grade students during the morning, divided into two 1.5 hours sessions. Options ranged from skiing, dancing, and ping-pong, to cookie decorating, tic-tac-toe, and D&D.  I was invited to offer Scratch coding.

My activity, Coding/Scratch, had this description: “Students will have the option to create a game, animation or pursue a passion project of their choice using Scratch 3.0 coding environment.”

Despite the unlimited options in the description, I wanted to offer some project guidance as I didn’t know the coding experience of those who would sign up. I decided on three projects from Code Club World that in my experience offer students the greatest creative choice coupled with step-by-step instructions.  The first option was Chatbot.  I’ve discussed how much I like this project before and with the added text-to-speech options in Scratch 3.0, I knew this would be a hit. The second option was a “clicker game” presented with Code Club World’s Ghostbusters project.  The third project was the “side-scrolling platform game” Flappy Parrot from Code Club World.  I feel any of these three projects can be accomplished in 1.5-hours with this age group.

In preparation, I went through and created starter versions of these projects. I also set up a Scratch studio for everyone to share their projects. Once the students were logged into Scratch (some had to make their own, new accounts), I invited them to be curators so they could add their projects to our group studio. This part required a bit of administrative time but it is not difficult and works well for everyone to have a single place to go to play each other’s projects. I feel it is important to carve out time to share and showcase what everyone has accomplished, knowing that we all had a limited amount of time and that the projects aren’t perfect or even finished.

About ten students signed up for each session but only one girl in each session.  One of the math teachers joined me- she is eager to learn Scratch and we work well together.  I knew more than half of the students and some of them were with me in past Code Clubs. I think the students had a good time. I definitely feel like we supported their ideas and creativity. I’d love to get feedback from them. I shared the project studio with the school administrators and they thanked me for participating.

Chungus Run – a creative Flappy Parrot game – good instructions, too 

Some notes from the sessions:

  • Time management is key with short sessions – I posted our schedule – Intro 10min/ Plan 10min/ Code 55min/ Share 15min
  • The project guides were helpful even if only to get them started before they went off on coding tangents.
  • These students showed creative, flexible thinking. Scratch supported their creativity by making coding flexible to their ideas.
  • It is difficult to share something you know is incomplete.  I announced a time check at 15 minutes before we wanted to share, so no one was caught unaware.

Fishie Click game – former 4th grade Code Club member

Coding projects are like art – they are never really “finished” or “perfect”.  They are “done” when you decide to stop working on them. – I said this to someone who was bemoaning the end of the coding time and another student laughed.  She clarified that she was an artist and understood that fact very well.

New Year, New Scratch

Creative Coders Club on Monday was one of our best sessions ever.  The kids were really creative and funny and fun to work with.  The kids that came were all returnees and familiar with Scratch.  It was their first time working with Scratch 3.0 and despite a few grumblings about where familiar tools went, they were able to create some creative projects.  For such young people, they really seem upset about the changes to their coding environment.  I’m sure they will get used to the new version and not look back.

When I was looking for a project this month I noticed the tutorial from Cartoon Network on Animating an Adventure Game.  I knew the Creative Coders had been wanting to make an adventure-type game.  I added this option to our January studio and went through the tutorial myself so I could field any issues.  It has some fun character Sprites but turns out to be a simple “collect the gems” game. I felt it was a nice option for the club.

I also looked at the Scratch Design Studio for January.  I’ve been looking at the prompts each month since the Scratch Conference in August, hoping to find one that would work for this club.  The current theme is the Year 3000.  I felt it would really bring out their imagination and creativity.

I started out our meeting with a “Happy New Year” and a question for them. Did things seem different now that it was 2019 or did things just seem the same?  I told them that when I was their age, computers weren’t for kids and that 500 years ago books weren’t for kids either.  Then we brainstormed about what the year 3000 would be like.  That was the first hook.

Then I read them the Scratch Design Studio description.  I really liked some of the questions it asks, like what will food be? like or how will we dance?  It sparks the imagination. They shared their ideas and I had a difficult time getting them to not share all at once.

Next, I showed them the project I made about the year 3000.

My sample Year 3000 project

The other hook was the text-to-speech extension in Scratch 3.0.  screen shot 2019-01-08 at 9.29.24 pmI had read that some of the tools from Scratch 2.0 – like music and pen blocks – had been moved into the extensions section.  When I went looking, I found the text-to-speech extension.  It is easy to implement and works great.

 

I knew it would be a hit with the Creative Coders, and I was right.  (My only worry would be about the appropriateness of the middle school students – and I let them know, a few times, what my expectations were).

Everyone incorporated text-to-speech in their project and everyone used it appropriately. Whew.

There is not much time in an hour to imagine and create a project but the kids managed to work hard and when I told them they had only 10 minutes to get something ready to share, a few of them revised their big ideas into something manageable.  Two (of ten) said they would finish later.

In the last ten minutes, I showcased the projects they made and added to our January 2019 studio.  We laughed and enjoyed each other’s creativity and imagination.

The very funny “So boring” Year 3000.

screen shot 2019-01-08 at 9.47.53 pm

Another very funny text-to-speech Year 3000 project.

I highly recommend trying out the text-to-speech extension blocks and the different voices.  It is a little tricky to have the “text-to-speech” and “say” blocks sync up (like closed-captioning) but is worth it to be able to see and hear the project.

I hope some of them submit their projects to the Scratch Design Studio and I hope next months SDS theme is just as fun.

Happy New Year and kudos to the Scratch team for a great new version!

Create Your Own World

I don’t usually blog in the summer, but I’m running a weekly summer code club at the library in July and I’m being a bit reflective about the monthly one that I helped lead this last year.

Earlier in the year, I introduced a new (to me, too) project to the Lebanon Library Creative Coders. We decided to take two of our monthly meetings, February and March, to work on the Create Your Own World project from Code Club World.  I knew this middle school age group would enjoy creating a platform game. One of them even continued to work on it for a third month and was able to add a lot of detail like hit points, inventory list, and bad guys.

World detailed with inventory, hp, weapon and bad guys.

The first meeting we focused on setting up the player movement.  We remixed Code Club Rik’s Resources for this project so we could jump right in with the coding.  When I was prepping for our meeting, I went ahead and changed the character from a square to an overhead view of a guy walking.  One of my original groups of students created Showcase projects called Tomb of Terror and Shadow Swamp with Hatty McWalker.  That’s who I was thinking of with this guy.

Screen Shot 2018-06-29 at 7.49.15 AM

Overhead view of my player.  I added a costume with the mirror image and a “next costume” block in my code to make him look like he is walking.

The Creative Coders were certainly creative with the movement options.  I’m used to using arrow keys for movement, but these middle schoolers liked ASWD and this creative ghoulish option with side arrows for turning and up for forward:

 

I’m finding it useful to look at the code more closely.  There are some interesting, creative coding going on and I’m seeing some misconceptions that will help me help them debug their code.

Well coded ASWD movement and wall checking

I’ve seen this forever-forever coding before. Something is not working like they expect and they try to solve it with nested forever loops.

Screen Shot 2018-06-29 at 7.27.37 AM

Nested infinite (practically) loops didn’t fix the problem – switching to the “play sound until done” block did.

Or they are checking for an event and forget to put in the forever loop:

Screen Shot 2018-06-29 at 7.55.25 AM

One time event checking?

This wall checking code has been separated from the key-press event giving no response.

Screen Shot 2018-06-29 at 8.02.31 AM

If touching wall move in all directions at once.

A couple of the coders explored more blocks where you can define your own.  This led to a teaching moment for me to explain how these function blocks worked.  It turned out less useful than my right-click to duplicate code suggestion.

 

 

All in all, they impressed me. In the moment I’m not always sure what is going on with everyone and even at the end when we stop to share what we’ve accomplished I don’t always know how they did.

Some of them didn’t want to continue what they had started the month before, but they were self-motivated and independent enough to work on their own projects.

I love that this crew is supportive of each other and willing to share their ideas and compliments.

I appreciate good, supportive commenting

Some of the same students have signed up for the summer session. I’m looking forward to it.
