Young scholars demonstrate the relationship between stress and strain, then graph stress-strain curves for various common materials. Students interpret graphed results and discuss differences in mechanical properties of materials.

Young scholars explore the mouth's environment and realize that there are bacteria in everyone's mouth.

Students accurately measure several common objects using the industrial ruler. They work individually to analyze whether given objects would meet the correct specifications required for a particular manufactured product.

Students view the video "The Invisible World" and discuss different types of microscopes and what can be seen with each type. They work in pairs to view several objects with a microscope.

In this online interactive vocabulary skills worksheet, students match the 10 vocabulary terms in the word bank to the appropriate definitions. Students may submit their answers to be scored.

In this ecology learning exercise, learners study the Air Quality Index in their area and complete 8 short answer questions related to this topic.

Students examine microscopes and how to calculate total magnification.  In this calculations lesson students complete an activity of calculations. 

Students study environmental health. Using actual NOAA satellite imagery, students investigate the basic concepts of mapping. They explore the relationship between monitoring satellite images and public health decision making.

Students identify how water moves through materials such as rocks or sand. Students measure the permeability of water through glass spheres to represent the movement of water in sand, an aquifer, or another sediment. During the...

In this microscope lesson students explore the compound light microscope. Students discover techniques concerning cleaning, storage and proper use of the microscope. Students discover the working parts of the compound light microscope as...

Pupils study craters and identify the different things that characterize craters.  For this crater lesson students create a model of an impact crater. 

Use this virtual model to simulate the basic operations and accuracy of a micrometer while manipulating the physical parts of the object.

This site boasts an extensive list of physics animations that cover topics such as electricity, magnetism, quantum mechanics, and relativity. Variables can be manipulated for each demonstration.

Learn about the relative size of nanometers, micrometers, centimeters, and meters by arranging objects, such as red blood cells, hair, and a penny, from smallest to largest.
