Students reinforce their knowledge that DNA is the genetic material for all living things by modeling it using toothpicks and gumdrops that represent the four biochemicals (adenine, thiamine, guanine, and cytosine) that pair with each...

Take this interactive, multiple-choice quiz over classification of organisms, then review your score and any missed questions at the end.

As an introduction to the study of diversity of life, science students will use hands-on inquiry experiments to discover the microscopic world through a microscope. Students will use computers to create a brochure or slideshow...

During the first session of this two-session lesson, young scholars use the different species represented in the PestWorldforKids.org's "Pest Guide" section to learn how living things are grouped together according to the characteristics...
