Different types of teeth have different roles. Third graders study how molars, incisors, and canines function in a rabbit skull and a cat skull. After answering some questions about the teeth of herbivores and carnivores, kids...

Students investigate the stripes in sedimentary rocks, using a structure at Petra, Jordan, as an example, and then do a hands-on activity using mixed nuts to illustrate the layering of sedimentary rocks.

Tree rings from North America give a continuous history of El Nino intensity over the last 1,100 years. Scholars learn how scientists use tree rings to create timelines demonstrating variations in weather patterns. The cumulative...

Take learning outside and start classifying grasslands. Young ecologists observe grassland plants in order to classify them into the appropriate species by family. They note their characteristics and where they grow. A true...

Four lessons spotlight a variety of professions while boosting listening and observational skills and making inferences. Lesson one challenges pupils to group cards based on a commonality then justify the relationship they see....

Learners will observe, measure and describe the phase changes of ice. In this science lesson plan, students observe ice as it changes phases. Qualaitative notations made by individual learners will be shared and compared.

Winter, spring, summer, and fall—take the learning of the seasons beyond the elementary level to the middle school classroom. Curious learners begin by watching videos about the seasons and the rotation of planet Earth. Then,...

Students explore the concept of parts making up a whole. In this parts and whole lesson, students come to understand that parts of a system must come together in order for the system to work properly. Students investigate items indoors...

Should gray wolves be removed from Yellowstone National Park? After researching the complex relationships between the various habitats and species at Yellowstone National Park,  including humans, class members take a position...

Combine math and science with fun in the sun! Scientists build a solar gnomon using reusable materials to calculate relative air mass. Mathematicians measure the pole's shadow and use the data to solve for relative air mass....

Why are muscles important? Third graders study the different kinds and functions of muscles in the human body. After drawing arrows in an illustration to indicate where a muscle contraction would occur, they do their own experiment about...

The mobilization of soldiers for World War II resulted in a worker shortage in the defense industries, especially in the fields of physics and other sciences. The Engineering, Science, and Management War Training program (ESMWT) was...
