Engineering Paper Cubes

Image
In a recent Computer Science workshop with 6th grade, students were challenged to replicate a Rubik's Cube in paper. They had to measure the cube and identify the different types of cubes that comprise the whole.

Then they had to devise a method for creating 3D cubes out of 2D sheets of paper. The class had recently worked through similar fold-able exercises so this step wasn't a big step for them.

Working in groups, they developed roles and processes to accomplish repetitive tasks quickly. Tape was found to stick better than glue.

They also had to color the model correctly. This can be challenging as students don't often realize that all 26 component cubes are different. They also needed to color the paper before folding which again emphasized the three dimensional relationships.

The entire project took a couple of days but less than an hour each day. Areas of efficiency students could have worked on would included cutting more patterns out of a single sheet of paper (les…

Using Spreadsheets for Life Decisions

Image
The best projects build current content on previous units and have an application that carries beyond the classroom. Occasionally, I create a culminating unit project that gets it right. 
We just finished a unit on spreadsheets: everything from basic construction to formulas and graphs. For me, the point of spreadsheets are to make sense of data collected. 
Organizing, sorting and charting helps us see the picture through the volume of data. This naturally leads to reporting what we find in the data. Without application, without impacting change, the data loses its meaning. 
"Truth that is learned but not applied, forms callouses on the soul."
This project asks students to compare five colleges in a total of nine areas. The way the data is organized and presented is intentionally left up to their discretion. This gives students the thrill of discovery. The focus is not on getting it right but telling the story. By pulling the data from their personal choices, they begin to t…

Rubik's Cube Workshop

Image
This week I ran a dissection lab in Biology - we took apart Rubik's cubes and reassembled them! Basically it was a lesson about the scientific process and problem solving.

Students had to devise a hypothesis on how the cube worked. My favorite idea was that there is a little bird inside like on the Flinstones. As students took the cubes apart, they needed to document their findings so it could go back together.

I pointed out that we typically look inside animals in science labs but don't often put them back together. But when we have surgery, we all expect the doctor to put us back together.

Students identified the different types of pieces that make up the cube and noted their relationship to each other. I asked if a corner piece could ever be an edge piece. After thinking about it and playing with the cube, they realized the answer is no. But I reminded them that if we let the cube sit for millions of years, eventually a corner could somehow evolve into an edge piece. I don…

My Philosophy of Education

Image
Every parent should sit down and write out their philosophy of education. It's not enough to value education, there needs to be a purpose and a method.

Once the idea is committed to words, it becomes a framework for educational decisions. Here's my personal philosophy of education, primarily as it applies to my own children, but by extension to how I train others.

"As declared by The Westminster Shorter Catechism, man’s chief end is to glorify God. Everything we do becomes an act of worship (1 Cor 10:31), including education. Man seeks to know God better through the exploration and understanding of his creation. The pursuit of knowledge and truth is actually the pursuit of holiness. Everything I teach should ultimately direct students back to God’s character."

A Big Decision

Image
Remember the Choose Your Own Adventure books? Each book could have several different endings based on the choices made while reading. In a way, our lives are similar. Everyday we have choices to make.

But sometimes we are faced with a decision so important that it can alter the entire direction of our life. The path of faith begins with a definitive choice, probably the most important decision you will ever make.

It was through the teaching of my kindergarten Sunday school teacher, Mrs Gilmore, that I understood I was a sinner and needed Jesus to save me from my sins. That afternoon I told my mom that I wanted to know how to be saved. She said that I could talk with pastor after the evening service.
My pastor loved kids but he was a very imposing man, especially for a five year old. But I was determined, knowing that this was something I had to do. So after church, while pastor was shaking hands with everyone at the door, I told him I wanted to be saved. He immediately asked a deacon…

iPod Sync with Rhythmbox on Ubuntu

Image
How converting to Ubuntu got more use from an old PC, without losing access to music files or juggling different music storage systems. Now Android and iPod can sync to the same music archive through Rhythmbox.

With Windows XP no longer supported, I converted our old PC over to Linux Ubuntu. We've been running Ubuntu on a laptop for a couple years now so everyone in the family is used to it. We mostly kept it running so the kids could play PC games, but they've slowly converted to Android app games on the Nexus 7 tablet. In fact, no one liked using the PC because it was too slow and cumbersome.

It does have an extra hard drive where we've archived all our old photos, records and most importantly, ripped music from our CD collection. I certainly did not want to lose all that data during the conversion. Our library is copied up to Google Play but it's still nice to access the original ripped copies. Neither did I want to rip 342 albums again.

Another goal was for my you…

Third Place Programming Winners

Image
I'm almost as excited as these guys were. They had about ninety minutes to build a game in Scratch based on the theme of fire. They knew their program was good. I only wish they were able to keep a copy of the game.

The two in the back finished in third place. Both guys received a water bottle, a t-shirt, and a can of silly putty. Official Press release from IUPUI detailing a couple of my students' 3rd place finish in the game programming competition:
INDIANAPOLIS— More than a dozen high school students from Central Indiana and Michigan place at the top among 127 competitors in the 2014 Computer Science Day at Indiana University—Purdue University Indianapolis (IUPUI). The event held Friday, March 21, was organized by the Department of Computer and Information Science in the School of Science. Students competed in one of three tracks:  game programming, intermediate programming + problem solving, and advanced programming + problem solving.The 2014 winners are:Game Programming

Vacationing With Facebook Lists

Image
Have you just returned from a spring break trip? Try using Facebook's Interest Lists to keep the fun going.

By compiling a list of places you enjoyed visiting, the vacation can continue long after returning home. We like to visit parks, and by following their Facebook news feeds we get a glimpse into areas of the park we didn't explore. We can also see what the park looks like in other seasons.

Or are you dreaming of warmer weather? Those same lists can help plan a summer vacation. News items can alert you to the best dates/times to visit. You could even fine tune your vacation schedule according to reviews and notices received.

The nice part about Interest Lists is that you can access the list news feed anytime. It becomes a convenient way to organize a large and diverse news feed. The same function could be accomplished in Google+ by creating specific circles around vacation destinations. Depending on the types of businesses you want to track, they may have a larger presenc…

Do The Cube

What can you do with 36 Rubik's cubes? Create amazing mosaics!

For the month of April I have the use of 36 cubes available through a lending library program. Check out all the details at www.youcandothecube.com

Watch for future posts about using them in the classroom!
