Organisms  (STC)
How is a pill bug different from a snail? Do a pine tree and a guppy have anything in common? By observing various plants and animals, you'll help students begin to understand the diversity of life around them. With the activities in Organisms, you'll encourage your students to observe the following:

• Similarities in living things.
• Differences between animals and plants.
• Individual differences within a species.

This is a very exciting unit for young students because they have a chance to observe, touch, hold, and care for a number of living things as they do the following activities:

• Plant seeds and observe and record their growth.
• Construct terraria and aquaria and stock each with plants and animals.
• Compare observations of the terrestrial and aquatic habitats in terms of the needs, behavior, and changes in the animals and plants in each.

Through their long-term observations, students will learn that animals coexist with plants as well as other animals. By closely examining guppies (male and female), students see observable differences within the same species. And due to the selection of the organisms in this unit, your students will see the diversity that exists in nature. Extensive use of Venn diagrams helps students organize their observations and draw conclusions about organisms in general.
