Discrepant events

Air Pressure: Balloon

Insert a deflated balloon into a plastic soda bottle and stretch the mouth piece to fit over the mouth of the bottle. Blow air into the bottle. The balloon will not be able to inflate because there is air trapped in the bottle around the balloon. Prepare a second bottle and secretly poke a hole in the bottom of the bottle. You will easily be able to inflate the balloon. Moreover, if you cover the hole after inflating the balloon, the balloon will remain inflated.

Jumping Flame

This discrepant event science experiment will allow you to light a candle without touching the wick. First, light two candles with a match or lighter. Allow them to burn for a full minute to build some heat. Blow out one candle and hold the second candle's flame just above the wick in the smoke that billows from the unlit wick. The flame from the second candle will use the smoke as fuel and connect with the first wick, relighting the candle. This occurs because all three requirements for creating fire are in place: heat, oxygen and fuel (the solid particles in the smoke vapor).

Ice Cubes in Water & Rubbing Alcohol

Materials Needed

·        ice cubes (made with food coloring for better visibility)

·         2 beakers (same size)

·         water

·         rubbing alcohol

Set Up/Instructions

1.       Fill one beaker with the rubbing alcohol and the other beaker with water before students enter the room.

2.       Place the ice cube in the beaker of water - the ice will float.

3.       Place the ice cube in the beaker of alcohol - the ice will sink.

Questions for Students 

1.       What happens when ice is put into water?  Think about a large glass of ice water.

2.      Why did the ice cube float in one liquid and not the other?

3.      What causes things to float or sink?

Common Misconceptions

Students will think that the ice cube will float in both liquids because both liquids are clear.  Student also believe that there is something special about the ice

Cultivator

Cultivators are used for soil cultivation. In particular, cultivators are used for weed control before planting into a bed, as well as incorporating crop or weed residues and preparing a seed bed. Cultivator tines can be properly spaced to be used in a garden bed or crop field after plants are growing to remove the weeds from around the plants. It takes someone with a steady hand to drive the tractor in a straight line and not hit the vegetable plants with the cultivator.

Solar Lighting:Solar Energy

One of the easiest ways to improve home efficiency is to add outdoor solar lighting to your property. Unlike traditional exterior lights, solar lighting requires no complicated setup as the lights are wireless and harness sunlight during the day to circumvent the need for grid-supplied electricity at night. Though solar lights are not yet as common as solar panels, they are quickly joining the likes of LED light bulbs and smart home thermostats as a cheap product that can reduce electric bills and improve the efficiency of your home.

Information and communication technology

ICT has opened up a wide range of new communication methods, allowing you to contact others for less money and over greater distances than ever before. Technologies such as texting, instant messaging and video conferencing allow users to communicate instantaneously with people across the world for a nominal fee, a concept which may have seemed ludicrous before the advent of computers. In addition, text-based computer communication can give those with speech or social problems a level playing field to communicate with their peers.

co-relation of science with other subjects

Co-relation of Science with other Subjects


Science and Languages:
Science is a practical subject, but it is very important for its learners to be able to express their views and ideas in clear and attractive form. For this purpose, it is necessary that they should have thorough knowledge of language which they use. Student who do not have good control over the language cannot express his views and various scientific laws and principles in front of others and especially in front of teacher.

To co-relate science with language subjects, (English , Hindi or Marathi) ---

1.  Students can be asked to write essays on some scientific topic. If student make any kind of grammatical mistake, then the teacher can ask him to make correction in his language. 
2.  Language teacher can give the task of writing about some scientific happening in the assignment designed for them.
3. There can be debate competition conducted on scientific topics.
4. Elocution competition can be organized on scientific topics.

Science and Geography:

1. Geography is the subject in which various concepts relating to earth on which we live are dealt with. Everything existing on earth, on different planets of the universe are also main subjects of geography. 
2. Which kind of crop should be sown in which kind of soils, how many kinds of rocks are found on the earth are some of the main topics which are covered by Geography. 
3. In science, various concepts relating to the atmosphere and earth in which living and non-living beings exist are made. For this reason, temperature, wind directions and measurement of rainfall are conducted in the subject of science by making use of various apparatus.
4. Results obtained by the science in terms of climate and the manner in which it affect the human beings and earth are being interpreted by subject of Geography. 

Science and History:

1.  While mentioning about the various scientific discoveries taken place in the earlier periods, teacher can relate with the major events of the world history. Students should be told about that what was the situation of science at the time of rule of various famous kings or rulers. Teacher should narrate some incidences which inspired various scientists to found out the medical remedies of various diseases. 
2. Mentioning the kind of living standard people used to have/experience at different parts of the world in human history. 
3. History of evolution of science from time to time.
