Fun with magnets helps you understand several important concepts such as the meaning of magnets, properties of the magnets, non-magnetic and magnetic materials, poles of a magnet, finding directions, making of a magnet, and repulsion and attraction in magnets. It also talks about the wonderful discovery of magnets.
In this topic, you will learn about motion and rest and how you can measure distances accurately. It covers a wide range of fundamental concepts associated with motion and measurement of distances. Some of the important topics covered are means of transport, standard units of measurements, motion and types of motion, measurement of length and measurement of heights.
This lesson teaches you that light is a form of energy. It tells you that tiny energy packets of light are called photons. It is the visible part of electromagnetic radiation having a wavelength of 400 to 700 nanometers and you can see the objects around you with the reflection of light; that is when light strikes the object and reaches our eyes, we see the object. Some of the topics covered are transparent , opaque and translucent objects, shadows, pinhole camera mirrors and reflection.
