Messin' with Mixtures
Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...
Teach Engineering
Air Pressure
Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...
Teach Engineering
Air Under Pressure
Introduce your class to air masses and how they affect the weather with a lesson that focuses on the differences between high and low air pressure systems. The class explores actual weather data using archived weather data.
Teach Engineering
Flame Test: Red, Green, Blue, Violet?
Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...
Teach Engineering
Global Climate Change
The greenhouse effect and its relationship to global warming is the focus of an activity that asks class member to consider the effects of climate change on weather. Pupils work with their families to determine their carbon...
Teach Engineering
Microbes Know How to Work!
Scholars harness the power of microbes with an engaging activity that uses yeast to break down sugar in water. Multiple setups of the same experiment lets learners determine which temperature results in the fastest rate of...
Teach Engineering
Light Intensity Lab
Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.
Teach Engineering
Bone Mineral Density Math and Beer's Law
Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson plan in the series of seven. Individuals work on practice problems with this law...
Teach Engineering
Density Column Lab - Part 2
Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...
Curated OER
Mice Rule!
Students explain what biodiversity is and how adaptive features are maintained in a population. In this biodiversity lesson students complete a simple activity involving mouse populations.

Weather Basics
Weather — there's more to it than meets the eye of the storm. With this resource young meteorologists learn about the basics of weather, including information about the factors that influence the weather, common weather vocabulary,...
Curated OER
Carbon Cycles
Students examine the carbon cycle and how carbon atoms travel through it. In this energy cycles lesson students describe how human activities affect the carbon cycle.
Curated OER
An Underground River
Seventh graders describe how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. They consider the affects of pollution on groundwater supplies and write a letter drawing...
Curated OER
Where Does All the Water Go?
Students view a demonstration of how groundwater flows and define several related vocabulary terms. They complete a worksheet, participate in discussion and make a poster.
Curated OER
Fighting Back!
Fifth graders inspect the basic functions of the immune system and determine how viruses and bacteria invade the immune system. They also explore what happens to the immune system in outer space.
Curated OER
A Recipe for Air
Students create a pie graph using M&Ms to demonstrate the composition of air. They label each section of the graph, and list the fractions from largest to smallest.
