Go deep in your paleontology unit with this spectacular set of slides! It introduces viewers to the types of fossils, a few famous fossils, and the geologic eras. This is done with easy-to-read text, diagrams, photos, and even videos. 

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

There are patterns in nearly everything — even earthquakes. Pairs research current earthquakes to see if there are any patterns. They determine the mean, median, and mode of the earthquake data, along with the maximum and...

The theory of keystone species in an ecosystem was first established in 1969 by Robert T. Paine. Pupils open the final lesson in a five-part series with a game guessing which member of the alpine ecosystem they are based on clues. After...

Clay's as good a material as any to build a boat, right? An introductory lesson 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 the...

Varve: a deposit of cyclical sediments that help scientists determine historical climates. Individuals analyze the topography of a region and then study varve datasets from the same area. Using this information, they determine the...

Fans of Sherlock Holmes may be surprised to learn that in addition to stories of the famous deductionist, Sir Arthur Conan Doyle is also the creator of Professor Challenger. An irascible, unpredictable scientist, Challenger was featured...

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

Did you know that leaky faucets waste $10 million worth of water? Conservationists perform an experiment and draw best-fit lines to explore how the US Geological Society determined this value.

Pupils explore the amount of water people use in agriculture and for personal use. They compare water usage for various crops to that of raising animals before considering solutions for increased access to safe drinking water worldwide....

It is recommended that you conduct this fabulous experiment as a whole-class demonstration. Collect air samples from the environment, human exhalation, and car exhaust, then compare them for carbon dioxide content using bromthymol blue...

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...

Bathymetry is not a measure of the depths of bathtubs! Through the three lessons, scholars explore two different types of maps and how they are made. The resource focuses on topographic and bathymetric maps and teaching the techniques...

From the highest high to the lowest low here's a resource that won't fall flat. Given data on the area and the highest and lowest elevations of each of the 50 states, learners decide which states are the least flat and the most flat. Of...

High schoolers explore igneous rocks by observing rock samples and considering cooling rates and composition. The third installment of a five-part geology series culminates in an activity where learners use igneous rock...

Pairs work as engineering teams to design and build model bridges from drinking straws and tape. In this third segment in a series of 10, teams compete in an attempt to build the strongest bridge. To help with the design, the groups...

By the 19th lesson plan in the 20-part series, scholars realize volcanoes and earthquakes are related to plate boundaries. The lesson plan extends and applies the knowledge by having individuals create a bumper sticker for one specific...

Change is coming — but how much? Geology pupils discover the transformation of metamorphic rock using a well-rounded interactive. Topics include the effects of pressure and temperature on metamorphic rock, how time factors into the...

Get your classroom rocking with this four-lesson earth science unit. Through a series of shared reading activities and hands-on investigations, young geologists learn about the three types of rocks and the unique properties of each.

Why was the obtuse angle upset? Because it was never right! A valuable resource is loaded with background information on types of angles and lines. Learners review the characteristics of parallel, perpendicular, and...

Get an in-depth look into erosion and deposition with a 23-slide presentation that details how gravity, water, waves, wind, and glaciers cause changes to the Earth's surface. Each slide consists of detailed images equipped with labels,...

Go on a tour of the ocean through the lens of a scientist. Learners read maps of the ocean floor, study tide behavior, examine wave motion, and analyze components of soil. Each lesson incorporates a hands-on component.

The rainforest, the Andes Mountains, and the Amazon River are all featured in this simplistic slide show. Intended to show the major geological features common to Latin America, this presentation provides only three geological areas...

Students create a model of a geological land-form. In this art lesson, students will create a model of a land-form using sand.
