A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Looking for resources that explore alternative perspectives of the Christopher Columbus story? Check out the images, videos, cartoons, primary source documents, and other texts in a packet designed to spark...

Get started with The Cay. First, provide some background information and images that relate to the novel. Then pupils can create double-entry journals. Once that is complete, read the first two chapters, encouraging individuals to record...

The Henderson-Hasselbalch equation combined logarithmic terms with the application of carbonic acid as a buffer solution. Scholars learn investigate equation and its applications through hands-on experiments. They collect data and...

Students take on the role of epidemiologists. They investigate an "outbreak" in serious birth defects that occur in infants born to teenage girls. students discover a link between the use of the acne drug called Accutane and birth defects.

Students in this inquiry-based experiment, put in the role of a method development chemist. The scenario they are given is that a train wreck has occurred resulting in a chemical spill. Students are told that the spill mixture consists...

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...

Third graders explore the capillary action of plants. They discover what makes paper "grow" when water is dropped on it. Pupils observe how paper reacts as it absorbs water. Students use a variety of saturate solutions to grow crystals,...

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.

High schoolers are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during...

Students explore the realms of measurement. In this math lesson plan, students analyze and solve problems in which rectangles with identical perimeters are compared to maximize or minimize area. This lesson can be extended for algebra,...

In a force diagram, a stick figure man in an elevator takes a ride. Physics analysts work out the force exerted on him by the elevator floor. As the acceleration changes, they draw new force diagrams and compute new force values. This...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

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...

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...

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...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

How have advances in technology and communication changed our world? That is the questions that world history students contemplate as they examine a series of primary and secondary source materials 

Can your class correctly classify plant species? Individuals explore native plants of the local environment and correctly classify them into their respective categories. They investigate differences in the plants and discuss similarities...

The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...
