Energy conservers investigate gravel size to discover if it impacts the amount of oil recovered in the extraction process. 

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...

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

What's that silly thing spinning in the wind? It's a whirligig! Explore wonderful windy whirligigs with a STEM-based unit that teaches the science and concepts behind these gigs. Scholars discover how gravity and air resistance...

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...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Discover the science of NASCAR! Young scholars rev up their learning as they explore aerodynamic principles. Hands-on activities help learners understand concepts of friction, kinetic energy, and potential energy.

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

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...

Young scientists find out what makes amphibians such unique and interesting animals in this simple life science lesson. After looking at pictures and discussing the characteristics of amphibians, learners complete a series...

Engage young biologists in exploring the mysteries of life with this collection of hands-on activities. Enlisting the help of numerous digital resources, students get an up-close look at the structure of plant and animal...

How important is the tip of a new shoot on a growing plant? Individuals learn about the results of experiments on shoot tips and must interpret them. They apply previous learning and connect complex ideas through advanced analysis.

Explore the food chains that support Arctic ecosystems. A class discussion on interdependence and the different roles plants and animals play in ecosystems provides students with the knowledge to complete a worksheet asking them to...

Fascinating reading about nanotechnology, nanoscale properties, and liquid crystals precedes a fun activity for young engineers. They measure their hands in nanometers, research, and then investigate how heat effects a sheet containing...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

It takes a strong foundation to build a house and a stronger one for a bridge. This resource presents the effects of geology and soil on bridge foundations. Working in groups, the class investigates the interaction of shallow and deep...

Reinforce concepts and encourage learner engagement with a collection of math games, science experiments, and cross curricular activities. In one fun resource, learners sort objects, keep a diary of everyday fractions, play a game using...

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

What caused the collapse of the environment on Rapa Nui (Easter Island)? Who constructed the Moai? What was their purpose? Class members assume the role of investigators and use evidence drawn from field studies, ships' logs, and...
