Light?<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>Light is a form of energy that helps us see things.<\/li>\n\n\n\n<li>It travels in a straight

Light<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Natural sources<\/strong>: Sun, stars, fireflies.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list
