A lot of math and science this past week of unschooling, along with some origami to round out the week.
September 22
We pulled out the Arduino kit and programmed a keypad to display a number on the screen. The project was quite challenging so we worked on it together, sharing the work as we put the electronic components onto the bread board. 
We had some errors and had to go through the code to find the problem. But once we did, the keypad worked perfectly. 
Ethan read about a thermometer project in a chemistry book. 
Doing some multiplication. 
Ethan wanted to try another coding project so he found one for creating an encrypting and decrypting program. 
It took some fine tuning to find the errors and correct them, but eventually, he got it to work.

Monday morning. He usually starts the day doing some math or science on Khan Academy. He usually follows his daily schedule that’s behind him on the green poster board. 
Learning about limits. 
Practiced Spanish using Duolingo. 
Learned about average velocity on Khan Academy. 
He watched a video about a strange pulsar. 
He then wrote about a weird binary star. 
Practicing vectors in math. 
Practiced the letter ‘b’ today in cursive. 
More vectors. 
From learning about average velocity. 
He added the Song Dynasty to his history timeline. 
September 24
He continued learning about vectors. 
He spent quite a number of hours building this Rubik’s Cube out of paper.
September 25
Off to nature school. 
Origami Pac Man that he learned from his favourite origami YouTuber, Jeremy Schafer. 
Several origami projects he worked on today. 
September 26
Working on math, right angle word problems. 
Learned about calculating projectile motion. 
His journal shows what he did today: Inverse trig functions in math and calculating distance when you know velocity in physics. 
Practiced writing the letter ‘g’ today. 
He answered some comprehension questions about Kawhi Leonard and the Toronto Raptors.
September 27
He learned about trigonometry with right angles. 
More about projectile motion. 
He learned about NASA’s Transiting Exoplanet Survey Satellite (TESS) and how it capture a black hole tearing apart a star. 
He then wrote about what he learned. 
He added some more information about the Song Dynasty to his history timeline. Not sure why the foot is there, though 🙂 
Spanish practice in Duolingo. 
The letter ‘j’ today. 
Solving velocity questions. 
Worked on trig functions. 
He organized his elastics. 
And then he did a lot origami for most of the night.

He was a little sick this week so he mostly hung out at home. Today, he made a device that shoots rubber bands. I asked if he learned how to make it from someone else, but he said no. He designed it himself. 
He spent a lot of time experimenting and making things. 
We went for a walk and he did this while we waited for Dong Eun. 
Bracelet for his mom.
And that was Ethan’s week. I’m sure there were other things he did, like violin class, taekwondo and swimming lessons that I didn’t include. But overall, it was another busy week on unschooling and SelfDesign.
