Solution for Aluminum Caste Plate
From TLC around 14 children and one teacher her name is Maya came to visit STEMland. They wanted to have an idea of how STEMland works and they want to have similar set up to their school. Children were curious about the way we work and the rules we follow.
Children were happy and they were curios to solve puzzles also they followed our STEMland rules. I felt that what they expected that was fullfilled for them on that day (Thursday 11/07/2019)
The 7th graders were working on measurements. The following scratch program shows how to find the area of a trapezium and parallelogram.
The 8th graders were working on percentages and finding the discounts. Sanjeev, taught the children on how to find the discount for a percentage using a graph sheet. Let’s see how to find discounts using graph sheet.
A book costs Rs. 500. The shopkeeper sells the book with 10% discount. What is the cost of the book?
1. Darw the X-axis and Y-axis.
2. Then on the X-axis mark the percentage(upto 100 with 1cm = 10 units)
3. On the Y-axis mark the amount of the book(upto 500 with 1cm = 100 units)
4. Then mark the point where the 100 from X-axis and 500 from Y-axis intersects.
5. Draw a ray from the point 0, crossing the point where the 100 from X-axis and 500 from Y-axis intersects.
6. Then for 10% discount we know that it is less 10 less than 100. So, it would be 90. So, from 90 in the draw a line that intersects the middle line.
7. Now, from the point that intersects the middle line from 90 draw a straight line to Y-axis.
8. This will give the amount which is 450.
~ Abilash, Pratap.
Abilash and Saranya made a relay circuit during the Electronic session with Vimal, so the goal was to turn ON and OFF the AC bulb with the delay of 1 second which was connected to the Arduino and Relay. The Arduino was connected to the laptop and bulb to the 230v Alternating Current through the relay. Pratap captured the video as a sudden surprise and made the learning rigorous.
In the morning session the insights from the previous day tool CFSR (Consious Full Spectrum Response) tool was processed by Poovizhi.
Couple of insights on CFSR (Consious Full Spectrum Response) are:
When I designed my project using the CFSR sheet I was able to see the challenges that would come when doing the project. It was clear and got more clarity about the project.
Then we did the tool Commitment for action behind complaint handled by Poovizhi and Naveen. This tool is about the three types of complaints and the way how the conversations can be shifted. After the insights from this tool we had a break.
After the break, the technical session was Scratch.
After the lunch break, we watched ‘Story of Solutions’. Murali took over the session in GeoGebra on Pythogoras therorem, Pie chart, Reflection and Refraction, Solar system and animations.
Solar System Project
At the end of the day participants learnt to use functions (blocks) in Scratch, how to find square root of a number and made their projects and most of them were able to do animations in GeoGebra.
2018 and 2019 passed out children 4 of them (Ajay, Rathnavelu, Sathish and Kbilan) came to learn something new in STEM land. They saw that we were working on scratch 3 using mindstorm so they also want to learn scratch 3 using mindstorm. They learned the mindstorm at STEM land also they already familiar with mindstorm. But they didn’t know how control the robot by using scratch 3.
Scratch 3 is a newer version of scratch. It has some new features. Which is controlling Arduino, Mindstorm and translator. They built hand and leg using mindstorm. They connected the mindstorm and scratch 3 through Bluetooth. Children did coding in scratch 3 and they have control the robot. It was wonderful that children were utilising there time in learning. Even though they graduate to other schools they were able to retain what they have learned in STEM land.
All the members of STEM land have switched to eco-friendly mode of transportation for their daily transport. We always cared about our physical health and environment as well, So we decided to try the KINISI electric cycles. Now we have rented 11 electric cycles and are using it effectively for about 1 month for our daily tranport. We got positive feedbacks from the entire team . Hopefully, we will be using these for longer duration.
This initiative from us is appreciated by many and is making awareness to others. We strongly recommend everyone to use e-cycles instead of motorbikes for a good cause(to keep the surroundings pollution-free and to keep yourself physically fit).
Visitor from Pondicherry. He has an experience in robotics by using Arduino. He wants to learn mindstorm so he visited STEM land. In our STEM land there is no hierarchy. If children knows which I don’t know I can learn from children also. That what happened at STEM land. He actually learnt from children only. He already knew how the mindstorm works but he didn’t do it by practically. He started coming to STEM land then he worked with our children and he learnt mindstorm. Now he is offering course on robotics. Here I am able to see sharing knowledge each other. Whateer we learnt we shared with him now, he is going to share about robotics.
Bharani from 9th grade has set an emergency alarm system in old puzzle solution box which gives a buzzer sound if someone opens the box.This prevents student from opening the box to see others answers.He used few materials like Battery,Buzzer,wires and clip.
The principle of this alarm is very simple.when someone opens the solution box ,the needle separating the clip is released , and the clip makes a closed circuit for the current flow which makes a sound.And also Bharani presented his project to his classmates and younger children in ISMART class. And students also tested his project.
