- They’re good at Flossing, aren’t they?
The Wimbledon Tennis Championships start next month. Is anyone interested in watching the tennis? Do you play tennis? Have you ever thought about the following:
What’s her name?
So, what challenges did you come across today?
How did you solve them?
Does your programming now work accurately enough?
Where will you attach your Micro:bit to your body and how will you do this?
How will you make it look attractive?
Is there a way to store a daily total and a cumulative total? ( I don’t know!)
The Polka has some really interesting activities over the half term holidays. Merton Park children went to see Error 404 a few years ago and we thought it was an excellent and thought-provoking play. Digiplay & Random Selfies also look very exciting. Let me know if you go?
What could possibly go wrong?!
*Don’t try this at home*
This week we began work on designing our own Micro:bit pedometers.
We first looked at a similar, existing product – a mechanical pedometer, and we played the roles of customer & engineer to decompose the pedometer and to work out what could go wrong and how the engineer could address this.
We took apart 2 pedometers and researched how they worked:
Early pedometers were entirely mechanical and they worked a bit like pendulum clocks (the ones with a swinging bar powered by a slowly falling weight). As the pendulum rocks back and forth, a kind of see-saw lever called an escapement flicks up and down and a gear wheel inside the clock (which counts seconds) advances by one position. So a pendulum clock is really a mechanism that counts seconds. The original pedometers used a swinging pendulum to count steps and displayed the count with a pointer moving round a dial (a bit like an analog watch). You fixed them on your waist and, every time you took a step, the pendulum swung to one side then back again, causing a gear to advance one position and moving the hand around the dial.”
We discussed the sensors that a Micro:bit includes and how they work, and compared these to the sensors in a phone. This will help us to design our Micro:bit pedometer.
A few children kept their pedometers on until next week and have been amazed at:
Did anything surprise you today?
Thanks to all of you who applied below, or on the Robo Blog – hopefully you have received an invitation to join Code Club! I’m looking forward to our first meet up this week. I think that Tim, Jon & Linda will be helping us out this term and hopefully Mr Hovell will make a few appearances too!
Since we are going to be creating with the Micro:bit, we will need to understand sensors:
