Question

Collect information about different aspects of each planet such as its distance from the sun, its diameter, its volume, etc. and present it in a science exhibition.

Answer 1

Planets of the Solar System – Facts and Figures (Exhibition Chart)

Name of planet	Distance from the Sun (million km)	Diameter (km)	Volume ($$\mathrm{km^3}$$)	Number of satellites	Special feature
Mercury	57.9	4,879	$$6.08 \times 10^{10}$$	0	Closest and fastest moving planet
Venus	108.2	12,104	$$9.38 \times 10^{11}$$	0	Brightest and hottest planet
Earth	149.6	12,742	$$1.08 \times 10^{12}$$	1	The only planet having life
Mars	227.9	6,779	$$1.63 \times 10^{11}$$	2	Red Planet, has 'Olympus Mons', the highest mountain in the solar system
Jupiter	778.5	1,39,820	$$1.43 \times 10^{15}$$	64	Largest planet, called the 'Stormy Planet'
Saturn	1,432	1,16,460	$$8.27 \times 10^{14}$$	33	Has prominent rings; very low density, so it would float in water
Uranus	2,871	50,724	$$6.83 \times 10^{13}$$	27	Its axis is highly inclined, so it appears to roll along its orbit
Neptune	4,498	49,244	$$6.25 \times 10^{13}$$	13	Winds blow at extremely high speed; one season lasts about 41 years

Points to remember while presenting

• Mercury, Venus, Earth and Mars are the inner planets. Their crust is hard.
• Jupiter, Saturn, Uranus and Neptune are the outer planets. They have a gaseous outer cover and rings around them.
• Except Mercury and Venus, all planets have satellites.

Ideas for the exhibition

• Make a big chart showing the planets in order from the Sun and paste their pictures.
• Use balls of different sizes (like thermocol balls) to show the relative sizes of the planets.
• Draw a scale on the chart to show the increasing distance of the planets from the Sun.
• Give one interesting fact about each planet, as shown in the table above.
