Young scholars conduct several simple lab activities to explore the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In this activity, students play the role of molecules in a...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

Individuals discover how to draw cubes on triangle-dot paper. They use cubes to build structures and draw corresponding isometric drawings on dot paper in the second lesson of the series of five. The activity also introduces the concept...

Taking the notion of symmetry to the next level, this looks at combining rotation and translation symmetry to build spiral symmetry in three dimensions. Using the Zome modeling system and an instructor’s guidance, geometers try to build...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Students analyze the amount of space required to pack round objects. For this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

Students apply the concepts of air pressure, the Bernoulli Effect, and angle of attack to build their own model planes out of paper, plastic, wooden rods, and drinking straws.

Fifth graders use modern technologies which allow them to gain a new, dynamic, and intersting understanding of themselves, their community, and the world. They focus on environmental education and the effect of the environment on plant...

In these creative hands-on activities, learners construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

In this estimating cell sizes worksheet, students read about the relationship between a cell's size and the rate of cell waste diffusion. Students solve 4 problems including writing the equation for the rate of waste exchange, finding...

In this Algebra I/Algebra II worksheet, learners solve problems involving direct variation.  The two page worksheet contains a combination of twelve multiple choice and free response questions.  Answers are included. 

In this online electricity worksheet, students are asked 10 questions about electric current and battery energy, an online answer key provided.

Learners discuss the importance of examining crystals and experiment growing them. In groups, they complete a project in which they use groups in geometry just like crystallographers. They practice solving the groups and proofs and...
