Simple ideas to scientific discoveries

Learning by scientific observation and making mistakes is fundamental to scientific discoveries. Many discoveries made years ago my not have been as accurate as the information we have today, but they led to other attempts or results that can be called fairly accurate.

We need not get perfect results every time we try finding or making something. The effort should continue. We may sometimes even find something unexpected and in an entirely different direction.

“I have not failed 700 times. I have not failed once. I have
succeeded in proving that those 700 ways will not work. When I have
eliminated the ways that will not work, I will find the way that will
work.” Tomas Alva Edison, on his experiments on the electric bulb

Take inspiration from stories of how discoveries and inventions were made to develop scientific thinking and method.

Interesting Fact: Water on Mars freezes at Zero Degrees Centigrade, but boils only at about Ten Degrees Centigrade. Why is it so? It’s a Hundred Degrees on the Earth for boiling point of water!

Watch the Magnus Effect in a basketball dropped from a dam.

Many simple things we observe around us could lead to practical inventions. The need is only to try and find the science behind the phenomena. Can you recall other simple, but amazing way things behave? Do you now the science behind it.

A similar phenomenon to observe is the Bernoulli’s Principle. Have you observed it around you? Post your response in the comments below.

My Wired Remote Controlled Car

Hey, yes! We made our own remote controlled car! It’s so much better to make our own toys, as compared to buying one from the toy store. We know exactly how it works and gives us the opportunity to modify and improve.

Making this car was the first step towards understanding how we control machines. When we later used a wireless remote in our programmable robot we knew what was going on behind the scenes.

Having Fun With a Wired Remote Controlled Car They Made – YouTube

Making the first wired remote controlled car was learning, struggle, and fun. In the end we made our own toys and had loads of fun playing with them,

The cars and kids pushed, banged, tumbled each other and had hearty laugh throughout. Now a machine was following our orders for the first time. Now we are ready to get some automation into the robots.

▶ Solar Eclipse: What you should know – YouTube

We watched this and some other videos on solar eclipse today with our students.

We were discussing IR remote controls and trying to understand what IR means. The topic turned to the light coming from the Sun, and there we were discussing eclipse. It was interesting for kids so we went on and kids could understand what solar and lunar eclipse really were. I think they were happy about this interesting new learning and wanted more.

We got back to making robots. However, I am sure kids will look forward to the next Solar Eclipse to experience what we had seen in the videos.

▶ A True Story About Planet Pluto and New Horizons

Pluto mission New HorizonsAll you wanted to know about the New Horizons Pluto mission is in this video. From what we already know about Pluto to what we expect to find and how. How the space probe was made to how it was sent on its mission.

 

What did college students have to do with New Horizons?

They made great instruments to go on such an important space mission and came out with flying colors.

Pluto (minor-planet designation 134340 Pluto) is the largest object in the Kuiper belt, and the tenth-most-massive body observed directly orbiting the Sun. It is the second-most-massive known dwarf planet, after Eris. Like other Kuiper-belt objects, Pluto is composed primarily of rock and ice and is relatively small, approximately one-sixth the mass of the Moon and one-third its volume. It has an eccentric and highly inclined orbit that takes it from 30 to 49 AU (4.4–7.4 billion km) from the Sun.

This video tells you about the status of the mission until it reached Jupiter nine years back. From then on until this year New Horizons has been mostly on hibernation (sleep).

Hydraulic Excavators made by kids

Hydraulic excavators made by kidsIn the mechanical design section children made  hydraulic excavators using modular parts. It uses sets of syringes and pipes as hydraulic/pneumatic system to make the arm work.

We were lucky that an excavator was at work nearby. We seized the opportunity to go an watch it, compare it to what we have made and know how are machine is very much like the real one!

In this video, our inventors tell us about what they have made, how and why. The audio is in Hindi, subtitled in English.
