Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...

Students use microscopes to investigate the diversity of life that exists in pond water. They then conduct a controlled investigation to study the effect of a pollutant (rice) on a microcosm ecosystem.

Seventh graders identify how much carbon is held by the world's forests. For this forestry lesson plan, 7th graders study the carbon cycle and discuss what role humans have had on climate change. Students write a one page paper on...

First graders investigate the causes of thunderstorms and create the sounds of a thunderstorm.

Seventh graders conduct year long study of water quality over different seasons using variety of probes, including D.O., pH, conductivity and temperature, that are attached to portable technology. Students select three data points in...

Fourth graders collect and chart weather data over the course of the school year either using tools at school or media resources. They agree on weather terms to use in their observations and write them on the assigned sheet. Finally,...

Students investigate water usage at school and at home. They use graphs and tables to evaluate water usage. Students describe possible water conservation measures. They use graphs and tables to relate data as part of a written report.

Students compile a collection of specimens, descriptions, and data that describe their local environment. They exchange this collection with another school and use their collection to determine the ecosystem surrounding the exchange school.

Students conduct an experiment to find out if there is salt in the ocean. In this scientific inquiry lesson, students pour a cup of salt water onto an aluminum plate and observe the changes over a few days. Students complete an included...

Students explain the causes of erosion, describe the effects of erosion, and devise a method of preventing erosion. They model the before-and-after-effects of erosion.

Students research information about pesticides. Students discuss the history of the Mexican fruit fly. They experiment to discover malathion concentration levels in organisms. Students explore the effect of toxins at the top of the...

Students complete readings on kite making and kite flying. They analyze how the parts of a system interconnect and influence each other. Students identifies and uses color and form in a 3D artwork.

Students model the soils layers using Oreo's. In this instructional activity students use their favorite food items to create a model of soil layers. A discovery instructional activity from a youth camp is adapted for classroom...

Students listen to the story "Clean Air, Dirty Air" by Lynne Patchett and discover the main types of pollution and how these affect their bodies. In this pollution lesson, students work in small groups to create a machine to prevent...

Young scholars explore the concept of the rock cycle.  In this geology lesson, students identify, classify, and observe three different types of rocks.  Young scholars then list and char the characteristics of their rocks. 

Learners explore energy properties by listening to a sustainability lecture in class. For this biomass lesson, students identify what biomass is, how it can be transformed into a usable energy and how it complements the energy cycle....

Though the website does not seem to have the mentioned video, a reding and lottery style games simulate the chances of finding intelligent life somewhere other than Earth. Without the video, this lesson is short, but it can be a useful...

Seventh graders explore skeletal biology. Through a discussion and video observation, 7th graders investigate how the anatomy is adapted to the environment. Students study primates and explore their characteristics and behaviors.

Young scholars predict and test different items to see if they sink or float. In this sink and float lesson plan, students predict whether an item is buoyant or not, and learn that size and weight do not matter when it comes to buoyancy.

Set up a demonstration of how gravity can drive the perpetual flow of water during your hydro power unit. Science learners work in teams to make observations and formulate questions about how it works. They compare the model to what they...

Pupils practice measurement using the Hudson River. They calculate the discharge measurement at a location on the Hudson River using ingenuity and a topographic map.

Students study water conservation. For this water conservation lesson, students participate in a water conservation experiment. Students discover how to conserve water while washing their hands.

Students construct their own pendulum. In this physics lesson, students design an experiment to find the factors affecting its period. They formulate a conclusion based on experimental data.

Pupils are introduced to the concept of biodegradability. In groups, they use the internet to research the types of materials that affect the process. They collect materials from their local community and develop an experiment to test...
