The video tutorial introduces the concepts of magnetism and gravity, explaining how magnets work and their interactions, as well as the effects of gravity on objects. It includes experiments to demonstrate magnetic attraction and repulsion, and discusses the role of gravity in everyday life. The tutorial is designed for 4th-grade science students, providing a clear understanding of these fundamental forces.

Where can you commonly find magnets being used?

• In a microwave

• In a refrigerator

• In a television

• In a washing machine

What type of materials are attracted to magnets?

• Metal

• Plastic

• Glass

• Wood

What happens when two magnets with the same poles are brought close to each other?

• They have no effect

• They repel each other

• They attract each other

• They stick together

What is the result when opposite poles of two magnets are brought together?

• They attract each other

• They have no effect

• They break apart

• They repel each other

What is the primary function of a compass?

• To measure temperature

• To show direction

• To calculate distance

• To tell time

What force causes objects to fall back to Earth when thrown upwards?

• Electromagnetic force

• Gravitational force

• Magnetic force

• Nuclear force

What happens to the speed of falling objects with different weights?

• All objects fall at the same speed

• Speed depends on the shape of the object

• Heavier objects fall slower

• Lighter objects fall faster

What would happen if there was no gravity on Earth?

• Objects would fall faster

• Objects would float away

• Objects would remain stationary

• Objects would become heavier

Which of the following is an example of gravity in everyday life?

• A car moving on a road

• A fruit falling from a tree

• A ball rolling on the ground

• A magnet sticking to a fridge

Why is gravity important for life on Earth?

• It keeps the atmosphere in place

• It provides energy

• It creates light

• It produces sound
