Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...

What do graphs of atmospheric gases over time show us? Do they indicate that carbon sources and carbon sinks are not in balance? Up-and-coming meteorologists watch video clips, read information, and analyze data from the HIPPO...

Young scientists discover the importance of scientific investigation by observing live crayfish. They carefully observe the patterns of crayfish in different environments. Then they discuss their conclusions and define what all living...

Pupils create trading cards for elements in the Periodic Table. Initially, they are introduced to the Periodic Table of Elements and the concept of elements in the world around us. After dividing into groups, learners use the Visual...

Talking about weather isn't just for making conversation. Young scientists gather evidence from an interactive activity to make connections between daily and seasonal weather. They analyze data from different areas and compare the...

After an explanatory introduction to sugars and enzyme activity, biochemists discover whether lactase is needed to digest lactose, sucrose, and milk as a whole. High school science lab skills are required for these investigations.

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

A well-developed lab sheet guides physical science learners through an investigation of kinetic and potential energy. In small groups, collaborators discover whether or not the ramp height or mass of an object has an effect on the...

This demonstration of solar ponds can be used in an earth, environmental, or physical science setting. Lab groups set up a solar pond and model how it is able, due to a salt concentration gradient, to maintain heat for future use. 

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

The cycle of energy is important to many different systems on Earth. Scholars use questioning and observation to investigate the differences between renewable and non-renewable resources and how they relate to global changes. They...

Build problem-solving skills with science! Step-by-step videos walk investigators through each stage of completing a science fair project. Scientists learn to formulate a testable question, design an experiment, collect data, draw...

The history of science instruction at Historically Black Colleges and Universities (HBCUs) is the focus of a lesson that explores the early challenges these institutions faced in accessing equipment for their labs and instructors for...

Explore science through problem solving and learning how to solve the problem of the story "The Three Billy Goats Gruff." Young investigators will learn how to construct a model and design a solution. They will also keep records of their...

Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

Physical science juniors will enjoy this sensational enrichment on aerodynamics, especially if they are also sports fans! With a focus on physical features and behaviors, collaborative groups make observations on five different golf...
