"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,...

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Common sense says that the farther a planet is from the sun, the longer the orbit. Kepler turned common sense into his third law by quantifying this relationship. Classes explore Kepler's Third Law through an interactive tutorial. They...

The world is full of patterns. Help learners quantify those patterns with mathematical representations. The first Algebra lesson plan in a compilation of four uses a series of activities to build the concept of patterns using multiple...

Is it bigger, or is it smaller—or maybe it's the same size? Individuals learn to describe enlargements and reductions and quantify the result. Lesson five in the series connects the creation of a dilated image to the result. Pupils...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Define the sharpest in the group. Given a section of a trail map, pupils determine a method to measure the sharpness of each turn in the path. Individuals then determine what modifications to their formulas to make to find the sharpness...

"Creativity is just connecting things." - Steve Jobs. After weeks of researching climate change, the ninth lesson in a series of 21 combines the data and analysis to address essential questions. It covers natural phenomenon, human...

Mathematics set notation can be represented through a computer program loop. Making the connection to a computer program loop helps pupils see the process that set notation describes. The activity allows for different types domain and...

If your learners are curious about human achievement, superlatives, or esoteric trivia, the Guinness Book of Records is a way to tap into instrinsic motivation and relevance. Here's an informational reading that will grab their attention...

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...

When told to describe a line, do your pupils list its color, length, and which side is high or low? Use a worksheet that engages scholars to properly label line graphs. It then requests two applied reasoning answers.

Explore Snell's Law using thin films. In the fifth installment of a seven-part series, pupils solve a set of problems relating to Snell's Law and use this skill during an experiment requiring the collection of reflective measurements...

One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.

Working with transformations allows the class to take a turn for the better. The short assessment has class members perform transformations on the coordinate plane. The translations, reflections, and rotations create pattern designs on...

Here is a (great) lesson on using parentheses! The task requires the expression of ages using algebraic expressions, including the distributive property. Pupils use their expressions to determine the individual ages.

Analyze data on a graph to answer three questions after a robot race. Learners practice comparing ratios and reading points on a graph. Answers may vary on the last question based on accuracy of graphing. Use the lesson along with...

A learning module on wage inequality based on gender. It includes several supporting questions accompanied by formative tasks and source materials, followed by a summative performance task. Students examine the difficulty in quantifying...

Learn about selective pressure and how genes are involved in adaptations by watching this video on pocket mice. The video focuses on the research of Dr. Michael Nachman, "whose work in the field and in the lab has quantified the...

While this 10-question multiple choice quiz is published to accompany Glencoe's Physical Science textbook, it covers the basics of matter classification taught in any course. Written in standardized test style, learners can take the...

The following tutorial provides an explanation of classification of matter by composition.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...

[Free Registration/Login Required] Discover the composition of matter and the relationship between matter, atoms, and elements. Students will learn the differences between elements and compounds, and how molecules are formed. Chemical...
