Using the NASA website, class members try to determine if changes could be detected in cloud cover, temperature, and/or radiation measurements due to the lack of contrails that resulted from the halt in air traffic after the attacks...

What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...

Illuminate your physics class with this examination of a photovoltaic cell. Teach the structure and operation of the device using a diagram. Then make a human-powered, larger-than-life sized model of a PV cell. Learners become electrons...

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

Learners examine natural selection, how it works and how it can cause microevolution.  In this evolution lesson students complete a lab activity that shows the effects that natural selection has on organisms.

Viewers learn about three different weather measurement tools in installment five of the 10-part Discover Your Changing World series. They build weather vanes to collect data on wind speed, barometers to determine air pressure, and...

 In this online learning exercise students answer a series of 14 essay or short answer questions explaining the DC generator theory. The correct answer is available to check their responses to each question. The questions vary in...

For this physics worksheet, students solve 12 problems on DC motor circuit. They make predictions and construct the corresponding circuit to verify if they are correct.

Young geologists get a glimpse beneath the earth's surface in this plate tectonics investigation. After first learning about the different layers of the earth and the constant movement of its plates, young...

Junior high schoolers explore possible theories for the cause of the Hunley submarine sinking. Through hands on activities, they investigate how to create a waterproof seal. Afterwards, they discuss how seals work and various...

High schoolers are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory

Students view video showing recent field work on a twenty two-year study of finch beaks on a small island in the Galapagos, showing natural selection clearly operating in the wild.

Two scenarios are presented for chemistry detectives to decipher. Both require the use of an infrared spectrometer and focus on the examination of polymer materials. In the first, lumps in polyethylene bottles are analyzed. In the...

Students, in groups, hunt for beans placed in the lawn. Each group uses a different tool (hand, spoon, fork, etc.) and there are three different colors of beens.

Students, in teams, use different colored paper chips to represent prey and a piece of fabric as the environment.

In this history worksheet, students use the questions to discover meaningful science and history connections. The worksheet is meant to be viewed online to access individual answers.

Students design an experiment to evaluate the effects of various treatments on the nitrogen cycle in a freshwater aquarium. They are required to maintain a laboratory notebook of all work, measure the key analytes of the biosystem at...

Young scholars study the theory of evolution and examine why it is so controversial.  In this biology lesson students view a video on evolution, research the theory of evolution on the Internet and complete an essay. 

Students identify the different types of bridges. Using the internet, they research information on how they are built by completing a scavenger hunt. Locating a specific area, they determine which type of bridge would be appropriate and...

Seventh graders identify the different parts and functions of the cell. In this biology lesson plan, 7th graders make a labelled diagram of either a plant or animal cell. They write a story about it.

Students simulate natural selection using pinto beans. In this biology lesson, students identify the factors affecting organism evolution. They record data from the experiment and formulate a conclusion.

Students find the mass of the top quark. In this physics lesson, students create a vector diagram from a given set of data. They discuss their calculations and findings in class.

Learners design and construct a battery (electrochemical cell). They works in a team to design and construct a working battery and is responsible for a labeled diagram of its operation. This engaging lesson stimulate their creative juices!

Young scholars compare and contrast the various types of rocks on each continent. In groups, the calculate the rock ages and types to determine if the continents, in their opinion, were joined at one time. They develop two imaginary...
