Greenhouse Effect
A greenhouse provides additional warmth and protection to the plants inside, but what if the greenhouse gets too hot? Pupils discuss and experiment with the difference between natural and anthropogenic greenhouse effect. They measure the...

Weathering and Soil Formation
A set of 27 slides systematically shows how weathering, erosion, and deposition contribute to soil formation. Both chemical and mechanical weathering are described, as are resulting soil layers and properties. There is no longer any need...

Give Me a Boost—How Gravity Assists Aid Space Exploration
The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

The Thermal Layers of Oceans
How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...
Curated OER
Greenhouse Effect
Learners investigate the greenhouse effect. In this environmental lesson, students investigate why the greenhouse effect changes the climate through an experiment. Learners use vinegar to simulate how acid damages the environment.

The Intertropical Convergence Zone
Young scientists know it is hotter along the equator, but why is it also rainier? Through the process of completing two experiments and a worksheet, scholars discover the answer is the intertropical convergence zone. First, they...

Reflecting on Reflectivity
Students plan and construct a "mini-lab" to measure the reflectivity of different earth surfaces. They measure reflectivity of materials, including ice, soil, rocks, etc., and then extrapolate from what they have learned to consider the...
Curated OER
Cities and Seasons
Students explore how satellite images show seasonal changes in seven cities in North and South America. Through a sequence of images, they study the green-up and brown-down of the seasons and how seasons change over time. Afterwards,...

THE WONDERFUL WATER CYCLE
Young scholars are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its...
Curated OER
Wind Power
Fourth graders develop an understanding of how engineers use wind to generate electricity. They will build a model anemometer to better understand and measure wind speed. They discover that engineers design wind turbines that generate...
Curated OER
Rocks and weathered rocks
Students connect rock and mineral formation with the changes rocks and minerals undergo at the earth's surface. They observe changes produced by weathering and relating these observations to chemical processes such as oxidation,...
Curated OER
Follow the Sun
Students use a simple model of the Earth and Sun as seen from space to explore the sun's apparent movement across the sky over the course of a day and year. They consider the apparent direction of movement and changes in the sun's angle.
Curated OER
The Water Cycle
Fourth graders explore changes in water forms. For this water cycle lesson, 4th graders build a water cycle model and monitor it for 2 weeks in order to understand that water changes state as it moves through the cycle.
Curated OER
Earthquakes
Students observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.
Curated OER
Season's Greetings
Students explore Earth's seasons using an interactive website. For this earth science lesson, students watch video segments and explain Earth's seasonal milestones. They discuss the factors that causes seasonal changes.

The Sun's habitable Zone
Students explore the average surface temperature of planets. They use the Planet Temperature Calculator to find the average temperature. Students explore how the distance from the sun affects the Earth's average surface temperature. They...

How Can We Locate Specific Places On Earth?
Second graders discover how to use longitude and latitude to locate specific sites on Earth. They compare old and new ways of locating specific places, and discover how latitude and longitude coordinates are used to locate places on Earth.

Lesson Plan: Global Warming
Students explore the concept of global warming. In this climate change lesson plan, students explore the provided links to PBS NOW sources and research the greenhouse effect and the effects of global warming. Students support their...

Water Pollution
Fifteen million children under the age of five die each year due to diseases in their drinking water. Water pollution is the topic of lesson 34 in the series of 36. Scholars, through reading and discussing, study numerous aspects of...

Sun and Moon Autumnal Equinox Activities
Two hands-on activities celebrate the sun and moon autumnal equinox. First, scholars create a cairn using a shoebox, flashlight, and drawing tools to view the sun's progression. Second, learners take to the kitchen to bake mooncakes...
