Let's Talk About Maker Spaces


Hello friends. What does it mean to have a maker space in your school? First of all, there is not a standard definition of what a maker space should be. It can be as simple as a corner of your classroom where students can tinker, disassemble a broken computer, make a truss bridge with craft sticks, or just experiment with some safe chemicals. The whole premise is to get ideas flowing, to fail and find solutions through trial and error, to answer the question what if? Or, it can be a dedicated room where there are many high tech machines that can create almost anything you need or want. The two primary factors are cost and space. You can make it what you want based on funding and space and your own comfort zone. The important thing is to get students tinkering, creating, being curious and making connections to real life….authentic learning. Just do it! 


Take the first step. Get out of your rut, step into a world where you learn along with your students. 
Your students will love the experience and will benefit in ways that you couldn’t imagine. 

Once I challenged my students to design a cardboard and duct tape boat that could hold two of them. The finished boat could have only one layer of water-proofing on the exterior. This simple challenge excited them so much that they were doing research on designs, building prototypes and discussing the best way to build their yachts. Of course, some just dove in and started building without any idea of how to do it, but isn’t that what it is all about? 

Learning by doing, failing, trying again, and finally reaching success. 

Too often, as teachers we want students to follow our guidelines because we are the “experts”, and for purposes of efficiency we can save time. But by making things easier for our students we are missing an important piece in the learning puzzle. Two key ideas, choice and trial and error, are critical to creativity and learning.

Hydroponics Strike Again!

I'm back in the classroom {greenhouse}!

I've finally graduate middle school...and in my retirement time am volunteering at our local high school ag department. I'm working with the agriculture teacher to start up aquaponics and hydroponics systems in the high school greenhouse.

I have ten students who have volunteered their free periods to work with me on getting these systems up and running.

Here Tyler is preparing the growing bed for the nutrient solution from the tilapia fish.

Our first steps were to obtain industrial bulk containers and cut the tops off to form the bottom tank and the top growing area. We had two of these tanks donated from Honey Acres in Ashippun, Wisconsin. Both will be used for aquaponics where we will grow about 100 tilapia over the next nine months.

I'll have more updates coming! In the meantime, if you want to try hydroponics on a small scale, check out these directions for a simple Windowsill Hydroponics system!

Windowsill Gardening

Red white and blue for Independence Day!

What a whirlwind. I can't believe that after 39 years I have officially retired from teaching! But don't think that retirement is going to slow me down...In fact I have a host of hands on learning and teaching opportunities already scheduled! The week after school, I taught a three day course to teachers on developing Makers Labs in their schools. We made hands on projects. We visited two Makers Labs in our area. We had fun while learning.

Not sure what a Maker Space or Makers Lab is? Check out our free download that walks you through the philosophy of it.

After this course, these teachers plan to initiate Makers Labs and Maker Spaces in their school buildings.


I also participated in a Fourth of July Celebration for 60 students at a local school to learn about Thomas Jefferson and the tinkering and inventing that he did. Then we made hydroponic planters from deli containers. The kids went crazy over them! I painted theirs red white and blue to fit the theme.


Check out how quickly this lettuce is growing! These photos were taken just one week apart!

Every Classroom - A Makers Space

What can you do with plastic bag ropes? Why not make a bridge!


I taught a Makers Space workshop yesterday to introduce the Maker Space concept to interested teachers. I led with a powerpoint presentation on the importance of hands-on learning and creative thought. We viewed TED Talks by Sir Ken Robinson and Gever Tulley

I led the teachers on a tour through our own Makers Lab and gave them some practice in hands-on learning in just a few of the areas that we do in our Makers Lab. I had the following stations for the teachers to tinker in:
  • Copper tape circuits
  • Foam cutting
  • Soldering
  • Spaghetti bridges
  • LEGO EV3
  • Brushbots
  • Truss bridges
  • Reverse engineering
  • Snap circuits
  • Sphero
  • Plastic bag ropes
  • Hacking an old computer
I also sent the teachers home with a CD packed full of some of our most popular products on Teachers Pay Teachers to help them get their own Makers Space running.

Aquaponics in Makers Lab - We've Got FISH!

We started lettuce and spinach just over two weeks ago. We have micro-greens ordered. When we see some growth, I'll get some photos posted!

Our other big news is that last Tuesday we picked up our tilapia fish for our aquaponics set up. We started with 44 fish this year. At the moment, we've only lost one!

Last year a week into our introduction, we had lost about 10 fish. We've made improvements this time around to prevent the losses we initially had last year.

Once of the changes is that we cycled the water longer with ammonia this year. I also think the clay pellets had old bacteria still embedded. When we brought the system up, I believe that the bacteria rejuvenated and is managing to break down the ammonia better.



We also had an great Makers Lab moment, which you can see in this photo (the fish are too tiny to capture a good photo right now, but this is the day we put them in!). We were having an evaporation issue and we need to add water every day. Our aquaponics system is on the opposite side of the classroom from our sink. We were running a hose across the floor (tripping hazard), rolling and unrolling hose each day (time consuming), and when we rolled hose there almost always was water spilled across the floor.

With a little finagling, we ran the hose up through the drop tiled ceiling and across the room. Now the hose stays in place, we save time, and have a safer and cleaner Makers Lab!

Makers Lab: Train Table Update


For the past several weeks our construction crews in the Makers Lab have been busy building by first connecting two tables, then attaching styrofoam to the tables, and using a hot wire knife to cut and shape pieces of styrofoam for two large hills on our train tables.

The first hill (the one you see above) is Holy Hill on the top of which sits Holy Hill Church a landmark that can be seen for many surrounding miles. We've also planned and sketched the roads and railroad tracks as well as Friess Lake.

We also have students working on constructing scale trees, foliage, and a replica of the Holy Hill Church. These are all to scale. We used Google Earth photos, saw the length of a car in the parking lot, we extrapolated the length of the building from the length of that car.

In the photo above, a student is applying plaster gauze to form the contours of the hillside.

The second hill will be a local ski hill complete with a chalet and a working ski lift (we hope!). All this will be done in N-Scale.

Middle School Design Day


We had a middle-school-wide Design Day with our sixth, seventh and eighth graders. We wanted to give children the experience of using engineering design principles.

The engineering design principle is sophisticated trial and error method. First you create your idea, then sketch it out. Next you build a prototype. Finally you build your final project. All along the way you are testing, revising and modifying your project.

We we set aside about 45 minutes for this challenge. The students were working in multiple rooms so that they had enough room to work. We gave them their challenge and sent them to work!

CHALLENGE
Build the tallest tower.

MATERIALS

  • Four half-sheets of newspaper per team
  • Four full sheets of newspaper per team
  • Duct tape
  • Pencil
  • Paper


Prototype materials: Four (4) half-sheets of newspaper and duct tape
Drawing materials: Paper, pencil
Final project: Four (4) full sheets of newspaper and 24 inches of duct tape



Students began by making a drawing of what they planned their tower should look like. They then constructed a small prototype. After which, they had about 20 minutes to construct a freestanding tower using 4 full sheets of newspaper and 24 inches of duct tape.

Here is the result. I didn't capture a photo of the tallest tower, but what I will tell you is that neither of these below are the tallest! The winner was over eight inches taller!

Makers Lab: Scale Model Railway and Local Community



When students in the Makers Lab are at a break in their own projects, they have a group project that they can work on. The class is making a replica of the surrounding landscape, roads, and railways on a scale train table. The train table is in the early stages. We believe that learning should be hands on and applicable to real life

The students had mapped out the local area and were beginning to make scenery using plants cut from their school prairie. Near the end of the class, Mr. Hoefs was showing them the next step: creating the Kettle Moraine glacier formations that make their local community unique in Southern Wisconsin. These glacial formations allow for stunning, albeit roller coaster-like, driving conditions during all seasons. In the coming classes, the students will begin forming these hills and valleys and the switchback main highway that runs through the stunning landscape.

Makers Lab: 3D Hologram Creation





Quiet and unassuming. I initially thought that Alex was avoiding me. I sat down next to him and asked him about his project. He's creating a 3D hologram. The day I visited, he was waiting on a shipment of glass that is thinner to arrive. But he was happy to show me his prototype that he has designed.

He has carefully drawn his pattern on the sheet of thicker and cumbersome glass. He showed me how he plans to us a glass cutting tool and then create a pyramid from the pieces. Once his pyramid is complete, he will create an iPad stand to shine the image from the top of the pyramid. The image will be, “cut into four pieces which will create the hologram,” as Alex explained to me.

I am astounded by these students. I am in awe. Each student is driven by a different motive. A different perspective. A different interest. But they are all equally enthused. It made me want to go back to school so that I could tinker and make right along with them.

Makers Lab: Magnetic Soccer Game


This is my last post from my visit to the Makers Lab last week. I'll be back to post updates on all of the projects in the next couple of weeks!

The enthusiasm of the kids is rubbing off on me as I hurry from group to group. I am nearing the end of the 45 minute class period and I hurry to the table next to Tyler programming and writing code, where Artie and Luke are creating a magnetic soccer board.

They are using cardboard for their prototype, but they explain that plywood conducts the magnets better so that is what they will use for their final product. They were using a hot glue gun and various magnets and metals to determine the smoothest playing. It was so fun to watch these two as they worked. They were a great team. They worked together and bounced ideas off of one another.

They were so happy to show me their work. Once they get their players glued onto their magnetic "skies" and moving smoothly on the board they will begin to move towards their final product. I can't wait to show you an update (and hopefully play a round or two! Seriously, who wouldn't want to play this game with these little magnetized-LEGO people?!). 

I can't wait!




Makers Lab: Solving a Teacher's Dilemma


“Mrs. N is always running late. This car will help her get between the Makers Lab and the math room faster,” explains Martina, a seventh grade student. “While traveling in style!” adds Rebecca, Martina’s classmate. Rebecca was using a handsaw to cut an axle. Their next step was to figure out how to connect the axle to the bike tires that they had disassembled from a donated bicycle.

I was impressed by the confidence in Martina and Rebecca. They were comfortable using a handsaw and a clamp. They measured twice before cutting. They were focused and enjoying themselves as they worked. And when the time came to clean up, they jumped in and helped their classmates clean up. In fact, they all worked together to get the Makers Lab back in shape for the next class.




Clean up time! The class worked as a team to get the room back into order at the end of the class period.

Makers Lab: A Doghouse for Lexi the Weimaraner

One of the first projects I noticed as I walked into the Makers Lab was a team of three boys, Cole, Connor and Mack. What stood out to me was their focus. Quite frankly, I remember middle school kids being flight at best. These kids got right down to business and worked for 45 minutes straight without goofing around, without whining, without acting out. I was impressed.

Connor, Cole and Mack are working on building a dog house for Connor’s weimaraner, Lexi. The dog house is designed to channel rain water from the roof into a water dish.

“We brainstormed and to solve a problem, we’re giving a dog water!” exclaimed Cole as he took a break from removing screws with a power drill. 

Their actual design wasn't matching up with their hand-drawn blueprints. They had to undo some work from their previous class. It’s all part of the learning process. It's all part of the hands-on learning in the Makers Lab. 








Underwater ROV in the Makers Lab



During my visit to the Makers Lab, Allie and Alyssa took a break from scenery creation on the train table (more to come on that in another post!) to show me their underwater submarine prototype. It’s a propeller-driven model that they created from a plastic coat-hanger, weights, electrical tape, a motor, wires and some C batteries.
Waterproofed motor
“We hot glued around the motor to cover the holes and then wrapped it with electrical tape to waterproof it,” Alyssa explained. 

They are waiting on a kit to arrive in the mail. Allie and Alyssa priced out the separate pieces of their final submarine, but found that purchasing the kit that the company offered would cost less because of the sales tax on each piece purchased separately. 

When their kit is complete, they will launch their underwater ROV in the local lake with a waterproofed camera to survey the bottom. They demonstrated their prototype in the aquaponics tub for me. Might as well put that tank to use while waiting for the water to balance so that they can add tilapia fish!

Going for a swim!

2014 Aquaponics in the Makers Lab



The Makers Lab is running full speed! I stopped in to photograph a few of the projects and I was so excited to see all the happenings. I was blown away by the focus and dedication of the students as they spend 45 minutes buzzing around the Makers Lab. The upcoming posts will highlight each of the projects.

More compact than last year!
One of the first things I noticed when I walked in the Makers Lab was the the aquaponics lab is built! It is significantly more compact than last year's model. At the top, the plants will grow. The water in the tank is pumping and you can see how it is aerated using the PVC piping with holes drilled in it. Adding the tilapia fish will is the next step!

What's Happening in MakersLab

Here we go again! Our middle school boys are building our second aquaponics system using an IBC (industrial bulk container). Here we're using a reciprocating saw to cut apart the metal frame of which the top will be our plant container and the bottom will hold tilapia. We encourage students to get their hands dirty with hands-on learning. We show them how to safely operate the Maker Space tools like the sawzall they are using above. Our goal is to help these students learn to think more creatively through the engineering design process. We encourage risk taking and failure that can help lead to success. 

In fact, this is the second year for our experiment. Last year we "failed" often with our aquaponics. But we revised and tried again. And again. And again. We learned a tremendous amount last year and are refining our design and methods to improve production this year. Keep watching for updates! 


Question: How many middle school girls does it take to carry a 4x8 sheet of plywood down the hall quietly?

Answer: It's impossible. It can't be done!!!!!!

These girls are working in the MakersLab to construct a scale model of the neighboring town of Richfield, Wis., including buildings, hills, landmarks and a model railroad system.  Keep watching for updates.

P.S. They did get it down the hall, but it wasn't pretty!!!

Blog Hoppin' - Where Tuesday

More on this fun Blog Hoppin' Week! Join in and read more!

Where are we at? We're in a kindergarten through eighth grade school in Southeastern Wisconsin. More specifically, I'll be in a middle school science lab and our Maker Space.

What is a Maker Space you ask? It's an incredible place for your students to invent and design using STEM/STEAM and engineering design principles. Last year our school received a grant to open a Maker Space for K-8. I eagerly took on the challenge of setting up the Maker Space, facilitating the students and managing the grant money. This year I will be working partially in the Maker Space and also as the middle school science teacher.

I shared a few days ago about what we'll be beginning the school year with in middle school science.

Our Maker Space is also getting up and running. Last year our eighth graders built an aquaponics lab from the ground up. They built the tanks from donated materials, built the plant stand from lumber and one student even created a robotic fish feeder to automatically feed the tilapia!

We grew lettuce, fish, and red worms in this particular set up. My role was to facilitate the project, but I encourage the students to problem solve, to research, to investigate and to invent on their own. I believe in the student-led education in the Maker Space. The students are more excited to learn and often dig in deeper than if they were teacher guided.

Our students also made a pneumatic tube system to sent items from our Maker Space to another classroom!

I'm really looking forward to developing our Maker Space even more than our first year. This is in addition to my already packed middle school science curriculum! I head back to school next week, and the kids follow right after Labor Day. I'm anxious and excited to get back and see what my students come up with this year!
