Remember the time when we had Mrs Jennifer Paykel come visit us the last time about the Experiment in how washing machines work and if they work with either low mechanical action and high chemical action or high mechanical and low chemical action. And guess what, you might already know which one was better and you guessed it low mechanical action and high chemical action!. But today was something new, today we learnt about different fabrics, why they shrink and how to stop them from shrinking.

We did many mini little experiments like the one with the plastic zippers, had a play with the cotton balls to learn how they grew and what grew them, using string and measurements to see how it evolved under the water and learnt how to work a  loom.

We had a fun blast having a go at all of these fun activities and a one I forgot to mention now was using different fabrics and how they feel on clothing. In which was able to guess the differences as one was fuzzy and the other smooth and soft. We had a fun time with Mrs Jennifer and we hope she can visit Point England School again. Thank you Mrs Jennifer for teaching us both washing machines and clothing!

Kia Ora and massive shout to Mrs Jennifer from Fisher & Paykel

Today at Year 7&8 Extension we have been learning all about coding Microbits. In case you don’t know anything about Microbits, they are like tiny computers with AI connected to them. At Extension we used Makecode Microbit AI to code our movement try to see if the Microbit can guess if we are either Shaking or Swinging. The site does this by recording our movement of running then as it recognises the same line graph as the one it first recorded. The parts of our Microbits we used to code was the processor, radios and LED lights.

Some things that didn’t work out however  was when we tried to make AI guess we were Spinning but instead of guess Spinning it got confused with Swinging. Because when it recorded both Swinging and Spinning the radio waves  were quite the same so AI though we were Swinging instead of Spinning so we had to change Spinning to Shaking.

I didn’t just do it by by myself I had a wonderful group of people to help me. Thanks to our teamwork we were able to record movement with AI.

I have learnt something new today which was how to code a tiny computer to guess or sense movement.If you have a Microbit I suggest you try this site out! In that case you’ll be able to code your Microbit to guesss movement! Hope you learnt something new as well. Please leave a positive comment on my blog.

Today at Year 7 & 8 Extension we had very grateful day when a nice lady come named  ” Jennifer ” who worked in a company called ” Fisher & Paykel “. Jennifer taught us all about the science of washing machines, in how they work and how they show Chemical Action, Mechanical Action and Thermal Action.

Mechanical Action means a physical interaction or movement involving forces and objects, often related to how things move or are manipulated.

Now Chemical Action process where chemicals interact, resulting in changes at the molecular level, often leading to the formation of new substances.

Then we have Thermal Action referring to the impact of temperature changes on structures, materials, or systems.

We learnt how to make theories and hypothesis’ with washing machines. Later on we got to do a Scientific Experiment with plastic bottles, cloths and detergent.

First we had to take the lid off our bottle then put in the first three cloths into our bottle, then Jennifer was to come around and put in a special cloth, then we were to put in the last regular cloths in. Jennifer divided the 4 into 2 with water and detergent and the rest with just water.

The two with just water had to shake the bottle, while the ones with detergent and water just tipped the water bottle nicely. We had to pass the four bottles around in a circle of seven after ten shakes each.

Then Jennifer emptied the water bottles, put the special cloth on a paper towel and next we had to carry the special cloth in the paper towel to an iron where we took out the special cloth and lay it under the iron to dry it. Then Jennifer is going now to take the cloths to test and see what is the difference.

Big Thank You Jennifer for teaching us the science of washing machines!
