Class 5 GK Worksheet: Science in Daily Life

GK lesson 26: Science in daily life · Set 149 · 40 questions

Remember (Spot the science): Magnets: pull iron, nickel, cobalt; like poles push apart, unlike poles pull together; a freely hanging magnet points north–south. Simple machines: lever (see-saw, crowbar), pulley (flagpole), inclined plane (ramp, slide), wedge (knife, axe), wheel and axle (doorknob), screw (jar lid). Solids keep their shape, liquids flow, gases fill any space. Renewable: solar, wind, water, tidal energy. Non-renewable: coal, petrol, diesel, natural gas.
