Satellite:Drone

Analogies can be used by the teachers for comparison with objects, machinery, design or shapes the students have probably seen.

One particular example of an analogy is Satellite:Drone

Satellite. Drone
Moves around in space. Moves around in
the air
Collects data in the form Clicks aerial pictures. pictures

Manned by a station on. Controlled by earth humans on the ground

Major point of difference between a satellite and a drone - Satellite is larger and complex compared to the drone. Satellite is sophisticated and designed to operate in space.

Correlation of Science and other Subjects

Science is a universal language that is spoken in every aspect of life. Curiosity drives Science and science is at the core of every object ever created, invented or discovered. From the grain of sand to the mighty mountains has science involved. So it is rightly justified that science be correlated to other subjects.

Correlation with Geography

As teachers it's common knowledge to proceed from simple to abstract concepts. Similarly during the teaching-learning process of Irrigation for std. VIII the teacher may retrieve the previous knowledge by asking the students about the variety of crops, the soil types, crops cultivated according to the seasons.

The teacher may probe on the moisture level based on the weather and then accordingly ask the students the method of irrigation to be employed in the various scenarios.

Correlation with Environment

The school plays a major role in creating awareness and educating the students about the issues we face with regards pollution and the mitigation strategies they can employ to safeguard the Earth for future generations.

Similarly in the teaching-learning process, of the topic Recycling of paper the teacher could educate the students about the 3 R's i.e. Reduce, Reuse and Recycle. The teacher should ask the students to use paper and not plastics by showing the ill-effects of plastic that has been polluting the marine ecosystem and thereby the organisms in the ecosystem.

Correlation with Fine Arts

Biology and diagrams are interspersed and hence the students will find the need to support their justification with a diagram. However, diagrams are not solely restricted to biology - physics and chemistry also involve diagrams.

The central dogma of biology

The central dogma of biology is the DNA encoding to mRNA that then specify the sequence of the protein that caused gene expression. In other words, central dogma means genes specify the sequence for mRNA molecules that then specify the sequence of the protein.Watch the link for the animated video for better understanding.
