Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...

This is not revolutionary, but it is informative. Earth science viewers in grades 7-12 get carried away with wave and wind erosion. They view diagrams of how waves impact ocean shorelines. They see examples of the different types of sand...

Students become aware of the history behind pizza and how it was adapted to the economic and geographic conditions of the United States. They have a basic understanding of the concepts of supply and demand.

Tenth graders organize information to explain how photosynthetic bacteria contributed to climatic changes that happened on Earth. Students create a timeline by using a storyboard to tell the story of the change.

Learners explore the world of inventions by utilizing Google Earth. In this global geography lesson, students research inventions such as the ball point pen, computer, telephone and typewriter. Learners use the Google Earth software to...

First graders define what a planet is and study the planet earth. They examine the effects of the sun on the earth and make a model.

Sunrise, sunset, swiftly fly the years! Your earth scientists can also fly through a year of daylight data. They analyze a graph and then answer five multiple choice questions about the rising and setting of the sun, the total number of...

In this science learning exercise, students read about the summer of 1971 when the Earth passed closer to Mars than it had since 1924. Students also learn about the retrograde motion of Mars as seen from Earth.

Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...

Demonstrate how the spherical shape of the Earth contributes to unequal heating of its surface and results in varying climates at different latitudes. This would be an illuminating addition to your meteorology lessons, especially when...

Students complete an online simulation of the greenhouse effect. In this lesson on the greenhouse effect, students use a website, similar to a webquest, to simulate and answer questions on how the greenhouse effect works. This lesson is...

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...

Hydrogen bonds, and polarity are described in this PowerPoint, and the reasons for tension and cohesion associated with water.  The states of water under certain conditions are explained with information about the changes in...

It is not a barrel of monkeys—it's a jar of worms! Scholars create a worm farm in a spaghetti sauce jar. Pupils layer moist soil, sand, and oatmeal to create a habitat for worms. Individuals place worms into the habitat, cover it with...

Don't let the energy of your classroom falter! Explore the scientific definition of energy through play. A hands-on lesson focuses on the change of energy from one form to another.

In this rock cycle worksheet, young scholars simulate the changes that occur during the rock cycle using a sugar cube. They use the sugar cube to represent a rock and perform changes on the sugar cube that represent the stages of the...

Students create flubber glaciers. In this glacier dynamics lesson, students experiment factors that may affect glacier speed. Factors include slope, ice temperature, and basal conditions. Students develop hypothesis, conduct experiment,...

The slope of the land is an important feature when considering the erosion that will occur. In this resource, which is part of a rain garden unit, learners calculate the slope of the proposed garden site. Even if you are not planning a...

After reading a short excerpt about Mercury, your class will answer four comprehension questions. The worksheet challenges them to fold over the paper and answer the questions without referring back to the excerpt. An answer sheet is...

Excite scholars to design their own planet in this first of five lessons. The instructional activity starts with a pre-activity assessment, a complete lesson plan that is easy to implement, and a post-activity assessment that would...

As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

How does the depth of an ocean affect the speed of a tsunami's waves? Use Jell-o, graham crackers, and marshmallows to model the effects of an underwater earthquake and its resulting tsunami. The lesson includes hands-on activities,...

For this atmosphere worksheet, students read a data table showing the percentages of carbon dioxide, oxygen, and nitrogen in the atmosphere over the last 4500 million years. They then create a graph comparing these gases over time and...
