Virtual Science Fair -2020-BUDDING SCIENTIST

Virtual Science Fair – 2020 – "BUDDING SCIENTIST''

In today's world, Science is not just a word. In every aspect of our life, science has become a part of our daily life. So, even in this pandemic outbreak we are proud to say that LAURUS The Universal School have conducted VIRTUAL SCIENCE FAIR.

The theme of the Science Fair for the Academic Year 2020-21 is "Budding Scientist". This program instils scientific attitude in our students to make them realize the interdependence of science, technology and society. LAURUS The Universal School provides this platform for the students and teachers where they can learn from each other's experiences and get motivated to design and develop something new and innovative project models and to compete with one another in science and technology activities. They present their science projects in the form of a report and models.

The efforts of the Principal, Science Teachers and Students to make this event an overwhelming success is appreciated

Our students showcased static and working models which can be used for learning various scientific concepts for children of the age group 12-16 years. The objective was not only to inculcate a scientific attitude and research mindedness but also creating teaching aids.

Students made still models, working models and posters to present their topics. The judges appreciated the students. They asked students about the scientific concepts forming the foundation of the models.

Students had prepared models like Rain-water Harvesting, Hologram Projector, Mathematical Concept based models. Charts based on Theorems of Circles and Human Nervous connection were presented well.

Each child is unique. They were encouraged to develop a scientific fervor and an attitude of research mindedness so that they develop the qualities of analytical and critical thinking further in their life

Experiment Model: Application of Trigonometry

DESCRIPTION:

The model helps to know the "Angle of Elevation", an important topic of Trigonometric Application. In this experiment we will learn the measurement of angles when a person or object moves.

MATERIALS Required/Used:

Colour papers, Ruler, 2 Protractors, Cutter, Scissors, Thread, White Cardboard and Small Nails.

PROCEDURE:

● Take a A3 white plain cardboard sheet. Draw some decent borders. And keep the heading as an application of trigonometry.

● Take some colour papers, cut them into a tree, a building, a tower, a girl and a small car.

● Take two protractors and make holes in the middle point. Now, insert the small nails into the holes. Tie the thread around the nail for both of them.

● Stick the girll to one of the protractors and the car to another. Then bend the nails at the back.

● Stick the building with the tower to one side and the tree to the other side. Take two nails and pin one on the top of the tower and another to the edge of the building. Make two rectangular holes between them.

● Finally, insert the protractor in the holes.

DEMONSTRATION:

If we pull the thread of the object, either the girl or the car moves and even the thread shows the angle between the line of sight and horizontal line in different places. This proves that the angle of elevation depends upon the position of the observer and the angle differs by the position.

When the observer sees an object, the angle is formed but changes whenever he/she moves. If he/she moves towards it, the angle increases and when he/she moves backwards the angle decreases.

When the object is below the observer, the angle between line of sight and horizontal line is called "Angle of depression".

This trigonometry and its applications were used by astronomers to calculate the distances from the earth to the planets and stars. Trigonometry is also used in geography and in navigation.

Experiment Model: Hydraulic Bridge – Pascal's Law

DESCRIPTION:

Pascal's law is the law that talks about fluid pressure in enclosed spaces. If a plastic bag containing water is hollowed with needles in some places, the water will gushed out. The emission will be stronger if the top of the plastic is pressed (squeezed). This indicates that the pressure is forwarded in all directions in water. Evidently, the emission of water that occurs stronger.

MATERIALS Required/Used:

Cardboard Syringes- 4 Vinyl tubes/PVC tubes – 2 A base Colour papers Glue A fluid- Oil

PROCEDURE:

1. Make a base with cardboard of 25cms

2. Take four cardboard pieces of 12cms and stick to the edges to look

like a pier

3. Take 2 pieces of cardboard of 4cms and make a hole in between to

pass the syringes through it

4. Connect the 2 syringes with vinyl tube; same with the other side

5. Glue the parts to make the model of a bridge

6. Stick two 10cms cardboard pieces on the either side of the piers to

make the lifting part of the bridge

DEMONSTRATION:

After we make the hydraulic bridge. This hydraulic bridge will only work simultaneously if there is pressure applied to the injection A. So the way this bridge works is by pushing or giving force / pressure on both injections A together so that the bridge can be lifted together as well.

Easy work this miniature. When the injection A is given force simultaneously, the pressure will lead to the hypodermic B. When the injection valve A is pressed causes water to press the injection valve B so that the injection valve B rises. This is because the pressure on the water will be forwarded in all directions if it is in a confined space.
