It's frog party time! With frog banners, frog juice, and a triangle hunt, your garden party is sure to be both entertaining and educational. The lesson connects geometry, earth science, and delicious snacks to teach kids about ecosystems...

Why do shadows look different in the summer than in the winter? What causes day and night? How can a sundial be used to tell time? Answer these questions and more through two engaging lessons about light and shadows. Fourth and fifth...

Geometry meets earth science as high schoolers investigate the cause and features of the four seasons. The effects of Earth's axis tilt features prominently, along with both the rotation of the earth about the axis and its orbit...

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson...

Is there a correlation between a country's wealth and the extent of its ecological footprint? What exactly constitutes an ecological footprint, and how does one country stack up against the rest? This is a unique lesson to incorporate...

Size within the solar system is a difficult thing for pupils to imagine. Using everyday objects, they build models to show the scale between the sun, moon, and Earth. They situate their props in proportional distances between the objects...

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...

Combines mathematical measurement with gardening skills. Third graders hunt for worms in the garden and try to find the longest one. They also measure and weigh vegetables that they harvest from the garden, measure rainfall amounts,...

Introduce your class to map projections and coordinates, the basics for the work done in a GIS, with an activity that uses Google Earth to challenge learners to think about the earth's shape. 

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 instructional activity includes hands-on...

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...

Come take a ride on the space bus! Scholars go on an imaginary trip to pick up their peers from the inner and outer planets while reinforcing math skills. First, learners round decimals to identify each planets' distance from Earth....

An average home produces twice as many emissions as an average car. Teach your class how to reduce energy consumption by replacing standard incandescent light bulbs with compact fluorescent light bulbs. Perform an experiment to compare...

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

Don't wait for a crisis to get your finances together. An economics lesson demonstrates the importance of understanding crucial documents, banking basics, and financial tools with the focus on Hurricane Katrina in 2005 and its effects.

High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.

Just how big is Earth's moon? With a hands-on simulation, scholars use Play-Doh to model the sizes of the planets Earth, Mars, Jupiter, and their moons. They make predictions as a class, work together to make their models, and discuss...

Bring the sun to your class! Young scholars analyze actual solar wind data in the second lesson of a five-part series. Their analysis includes speed, temperature, and density data.

Turn up the heat! Young mathematicians develop models to represent different climates and collect temperature data. They analyze the data with regression and residual applications. Using that information, they make conclusions about...

Learners will examine the layers of the Earth. In this geology lesson, students create a scale model of the Earth's interior using cash register tape. They will determine the percentage of error in the scale compared to the actual size...

Pupils explore the concept of collecting data as they collect data on their graphing calculator about time, temperature, and light. Learners plot the data and create histograms and box and whisker plots to analyze the data.

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...

Students work together to compare and contrast Mars and Earth. Using the internet, they answer questions given to them by their teacher and calculate answers showing their work. They graph their answers and discuss the results of the...
