Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-instructional activity worksheet to help focus pupils on the task at hand. 

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson, learners use scientific equipment to collect...

Sometimes scientists learn more from unexpected findings than from routine analysis! Junior oceanographers dive deep to explore hydrothermal vent communities in the fourth lesson in a series of five. Scholars examine data and look for...

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the...

Students introduced to the interior structure of the Earth. They explore how the Earth's interior is broken down according to both it's physical properties and it's chemical composition. Students explore how convection currents within...

Tenth graders investigate the carbon monoxide level at a fixed latitude to determine if there is a relationship to population density. They download data sets and generate a graph, and find locations using the Earth's coordinate system....

Learners role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.

Students build a scaled model of the solar system. In this space science lesson, students arrange them according to their distances from the sun. They analyze each planet's unique features such as density and relative gravity.

In this rocks and minerals worksheet, students calculate the percent deviation from various mass measurements taken of rocks or minerals. This worksheet has 10 problems to solve.

Students study how fluids of differing densities interact with one another, how densities of fluids can be changed, and how density currents transport and deposit tremendous amounts of sediment in lakes and in the ocean.

Clay's as good a material as any to build a boat, right? An introductory lesson plan sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure...

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

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...

Students conduct an experiment using sand, a jar, and a paper clip to analyze the effects of different kinds of sand vis a vis its sediment. They graph their findings and analyze for factors of size, shape, and density.

Students watch a demonstration using a Slinky during a lecture on basic wave properties. Properties addressed in the demo include wave speed, wave length, amplitude, period, and frequency.

Students explore environments and wildlife of Ireland to find out how they were formed, and how they helped form Irish culture. Students research online to determine connections between present elements in Irish culture and wildlife and...

Why are greenhouse gases called greenhouse gases? Young Earth scientists learn about greenhouse gases though experimentation in the second installment of a 3-part series. They use lamps to model radiant energy as well...

Students investigate the geological, climatic, and biological features of Big Sur. They watch a video, conduct Internet research, and create a script and images in the form of an outline in a simulation of an environmental group.

Students explore the field of nanotechnology by examining magnetic field strength in ferrofluids. They use probes attached to a computer program to determine the relationship between magnetic field strength and magnetic field lines.

Students explore various methods for visualizing the results of hydrogen wave function. They observe trends using a polar plot tool and make plots for the first three energy levels of the radial wave function for hydrogen. Students apply...

Pupils conduct an experiment using soil and shoeboxes to explore factors controlling and affecting the slope of a hillside. They analyze angles, surfaces, etc. to gain an understanding of instability of slopes.

Students discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes. They...
