Compounds take on different properties than their elemental components. How can scientists determine those elements? A lab-based activity has learners explore several double replacement reactions to analyze compounds qualitatively. They...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

Use data from the 1855 New York census to better understand the Irish immigrant experience during the late 19th century. Young historians analyze information from the census and build three hypotheses regarding the residents of the Five...

Earth's energy budget should be in the red. Young researchers review satellite data in a presentation to study Earth's solar radiation. They make both qualitative and quantitative observations about variations in available seasonal...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

The Henderson-Hasselbalch equation combined logarithmic terms with the application of carbonic acid as a buffer solution. Scholars learn investigate equation and its applications through hands-on experiments. They collect data and...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

How have advances in technology and communication changed our world? That is the questions that world history students contemplate as they examine a series of primary and secondary source materials 

What is in that double helix? Explain intricate concepts with a variety of creative activities in a lesson plan that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history of DNA...

The third lesson in a series of 11 begins by using thermal decomposition of potassium chlorate to determine the mass percent of oxygen. Then a second activity allows scholars to demonstrate that the resulting residue is from a...

Add a splash of color to your chemistry class! Science scholars discover the principles behind color through a wide variety of hands-on activities. Lessons include dyes, chromatography, and flame tests.

Teen-aged scientists analyze a graphic organizer of how trash is removed from New York City and then answer standard questions about a graph and a diagram. Resources are mentioned, but there are no links to these resources, so you will...
