Students study plots and use a Live Access Server to generate plots.  In this temperature lesson students examine the process of incoming and outgoing radiation. 

Field study groups collect samples of stream water and identify the macroinvertebrates found. Using their data, they calculate a water quality index to rate the health of the stream. They graph their data and discuss the value of a water...

Communicate chemistry clearly with a concise guide to writing chemical equations. It covers everything from the parts of a chemical equation to the different types of reactions that budding chemists may encounter.

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Students participate in lab activities in which they examine immersion, stain resistance, and stress cracking of synthetic polymers. Students use their collected data to discuss service applications and possible performance of materials.

Third graders use logic and knowledge of mathematics facts to solve problems. They see that pigments can be broken down into separate colors. Pupils recognize the capacity of water to move upward and measure the height water travels up...

Students participate in classroom experiment to gain better understanding of type of environment brine shrimp can best survive. Students then explore effects of common saltwater pollutants on survival of animals in sea.

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

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...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Not only do mealworms taste great, they are also great for classroom science lessons. In pairs, young scientists observe and record what they see as they check out what their mealworms are doing from minute to minute. Each minute...

There is a specific zone, or distance from a star, that a planet must be in order to have water in a liquid form. The activity demonstrates how flux density depends on its distance from the source. A photovoltaic cell gets power to...

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.

Pupils observe the effects of water on four different packing materials to determine which ones are more soluble. They then decide which material would be a good packing material to use for the environment and which may be a bad choice...

In this online interactive English vocabulary skills worksheet, students answer 10 matching questions which require them to fill in the blanks in 10 sentences. Students may submit their answers to be scored.

Students demonstrate understanding of shadows by creating a physical model of concepts taught.

Students review what a cylinder is and how a cylinder is measured. They build a variety of cylinders with different heights and radii. They compare the surface area and volume of each cylinder and discuss anything that surprises them...

After visiting websites about the Special Olympics, your class creates trading cards about people with disabilities and the adaptations that have been made for them in sports. 

Review questions like these can be used in your biology, chemistry, physics, or earth science classes! They assess scientists' understanding of laboratory measurement tools including graduated cylinders, thermometers, and balances. They...

In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

Students explore Earth science by creating a scale model in class. For this shadow lesson, students research the impact the sun has on Earth shadows and complete a space science worksheet. Students create models of the Sun and Earth and...

Students will construct models to demonstrate their understanding of shadows. Many questions and suggestions for variants on the activities are presented to allow you to tailor this lesson plan to your particular needs. It is best to...

In this energy lesson plan, students create calorimeters out of soda cans and use them to calculate the amount of energy stored in different types of wood.
