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...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Small and large are relative terms; what's the best way to quantify them? Young scientists take on that challenge as they complete an interactive activity to explore size. They build structures during their exploration and begin using...

Why is star gazing easy on some nights and difficult on others? Pupils aim to quantify the answer in an enlightening astronomy lesson. After collecting images from an online robotic telescope, they measure the brightness of images using...

Tuition costs are always on the rise. Help your classes quantify this change using real tuition data. Future college scholars analyze data from 2012 and compare it to current tuition rates with a graphical analysis.

The right to public education was not always so clear in American history. Readers study several primary and secondary source documents, including property deeds, maps, and photographs, about the founding of local schools during the...

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Desert regions are hotter for multiple reasons; the lack of vegetation causes the sun's heat to go straight into the surface and the lack of moisture means none of the heat is being transferred into evaporation. This concept, and other...

Attracted class members to an activity-packed journey through the science behind the invisible forces at work all around us. From jump rope generators to junkyard wars, there's never a dull moment when eighth grade physics scholars...

Who's your Daddy ... and Mommy for that matter? Given a first-generation group of gummy bear offspring, young scientists must determine which bears are their parents. An activity worksheet covers the differences in genotypes and...

Dust is everywhere around us; it's unavoidable. But what exactly is dust and are certain locations dustier than others? These are the questions students try to answer in an interesting scientific investigation. Working independently or...

Raise children's awareness about the importance of conservation with this hands-on science lesson. Start by breaking the class into groups and having them collect trash from around the school or local park. Students then use the provided...

How many humans does it take to power a light bulb? The 10th part of a 25-lesson Energy Systems and Solutions unit has learners conduct an experiment to calculate power. They then use the results to determine how many classmates they...

Which fluids make the best bubbles? Pupils experiment with multiple fluids to determine which allows for the largest bubbles before popping. They gather data, analyze it in multiple ways, and answer analysis questions proving they...
