Science and Technology in production of energy

Hydro Power Plant:

Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

Science and Technology in Manufacturing

Silicon Rubber



Silicone rubber is an elastomer rubber-like material) composed of silicon—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from -55 °C to +300 °C while still maintaining its useful properties. 

Due to these properties and its ease of manufacturing and shaping, silicone rubber can be found in a wide variety of products, including: automotive applications; cooking, baking, and food storage products; apparel such as undergarments, sportswear, and footwear; electronics; medical devices and implants; and in home repair and hardware with products such as silicone sealants

Science and Technology in agricultural field

Throughout history, scientific and technological advances have greatly impacted the agriculture industry.

1. Corn Picker

A corn picker is a machine used on farms to harvest corns stripping the stalks about one foot from the ground shooting the stalks through the header to the ground. The corn is stripped from its stalk and then moves through the header to the intake conveyer belt. From there it goes up the conveying system through a fan system, separating the remaining stalks from the ears. The stalks blow out the fan duct into the field while the ears drop onto another conveyor belt. The ears ride the belt and drop into a large moving bucket.

This method is done with both Fresh Corn and Seed corn.

The first mechanical corn harvester was developed in 1930 by Gleaner Harvester Combine Corporation of Independence, Missouri.

2. Gasoline Tractor


In 1892 John Froelich built the first gasoline-powered tractor that propelled itself backward and forward. His invention helped pave the way for modern farming.

Discrepant event 4)Sparkly volcano

Sparkly Volcano



Combine the terror of an erupting volcano with the joy of glitter to create a sparkly version of a classic science experiment.
What you'll need:
  • A tall vase
  • Baking soda
  • Vinegar
  • Red food coloring
  • Blue glitter
  • A tray to hold the mess
Pour a good helping of baking soda into the bottom of the vase. Add a healthy dose of red food coloring and toss in the glitter —the more sparkles, the better! When you're ready, pour in the vinegar and stand back. Your volcano will erupt in all its glittery glory.
It works thanks to a chemical reaction. The baking soda is a base and the vinegar is an acid, and when those two meet, look out! The glitter is just for fun.

Discrepant event 3)Pepper on the run

Pepper on the run


Send pepper running with this simple surface tension experiment.
What you'll need:
  • Pepper
  • Dish soap
  • A bowl of water
Pour a generous amount of pepper into the bowl of water. Most of it should float on the top. Put a drop of dish soap on your finger and touch the surface of the water. The pepper will scatter to the edges of the bowl!
This is due to surface tension — a property of water that allows it to resist outside forces. Common dish soap decreases water's surface tension, causing the water in your bowl to spread out and take the pepper with it.

Discrepant event: 2)Rainbow in a jar

Rainbow in a Jar


Somebody tell the Double Rainbow guy that science is the key to his eternal happiness. You can make a rainbow (or two) right in your own kitchen.
What you'll need:
  • Large mason jar
  • Light corn syrup
  • Olive oil
  • Blue dish soap
  • Water
  • Food coloring (red and green)
  • Small mason jars (or other containers for mixing)
Prepare each layer of the rainbow in separate jars. Use equal amounts of each material (two cups of each will give you nice thick color bands).
  • Add red food coloring to the corn syrup
  • Add green food coloring to the water
  • Olive oil is already yellow.
  • The dish soap is already blue.
Pour the liquids one by one into the large mason jar in this order:
  1. Red corn syrup
  2. Blue dish soap
  3. Green water
  4. Yellow olive oil
The liquids won't mix together. Instead, you'll get separate bands of each color. This experiment works because each liquid has a different density, and certain liquids (like oil and water) refuse to mix.
