In this animal worksheet, students review characteristics of animals including body symmetry, development, and skeletal structure. This worksheet has 3 short answer questions.

Young scholars examine worm habitats. In this animal habitats lesson, students participate in a lab activity that requires them to explore the adaptations that earthworms make to their environment.

Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

Students explore the nature of water and water molecules. They examine the role of ice on organisms.

After studying the different aspects of atoms and their reactivity, pupils will find this summary PowerPoint useful for review. Some of the slides are informative with labeled diagrams; others give important vocabulary. Teachers may want...

An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Students hike a local mountain and examine its life zones. They measure various components at each zone and collect leaf litter at the sites. At the mountain top, students make descriptive observations and complete a handout about the...

Elementary schoolers identify the ocean floor in a geological sense. They create a presentation that highlights the key features of the ocean floor. This terrific lesson plan has excellent streaming video segments embedded in it, and the...

What's in the water? Encourage your class to further explore this question and learn about pond ecosystems, food chains, and food webs as they complete this hands-on activity. They view the environment from a new perspective...
