Additional articles:


Make a chart listing all the planets. For each planet list at least two significant details. Children may wish to draw the planets (as seen on page 36 and 37) as well. Examples of significant details could be how the planet appears in the sky, or how hot it is, what its ‘atmosphere’ is made up of, etc. Be creative!
