Algebra learners look at equivalent expressions in the context of three different operations: division, squaring, and absolute value.  In comparing these values, they will identity when expressions are equivalent. 

Fourth graders engage in a study of sound pollution at their school. After a class discussion on what noise pollution is, learners are asked if they think there are areas of their school or community where noise pollution is a problem....

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

Eighth graders watch segments of CBS's Street Cents and discuss approaches used on the program. They create standards for various items and learn why they are important to have. They test different fabrics to explore clothing standards.

Students investigate the results of different propulsion methods. In this propulsion lesson, students measure the distance a test toy car goes using different types of propulsion. They record the distances in data tables before...

Eighth graders explore and demonstrate the seven steps of the scientific method. They predict how much sugar is in chewing gum and test, analyze, and calculate the sugar content of gum.

Students explore the scientific method. In this science lesson, students create and conduct a science investigation for the science fair.

Students determine the average speed of a toy car as it travels six different distances set up by Students. Three trials are done for each distance. The only requirements is that the longest distance must be at least three times longer...

Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.

Seventh graders conduct year long study of water quality over different seasons using variety of probes, including D.O., pH, conductivity and temperature, that are attached to portable technology. Students select three data points in...

High schoolers explore the relationship between pressure and vessel diameter. They are given an open-ended design challenge in which they engineer their own remote repair device. Students see a model that represents how elevated blood...

Students observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.

Ninth graders investigate the techniques of culturing bacteria. They culture bacteria using agar plates. Students identify and describe some environmental conditions that effect bacteria growth.

Role play community members who are both for and against the construction of a dam. Research the pros and cons and then hold a classroom debate. This activity ideally follows a series of stream studies, links to which are included. Use...

Using a famous children's story as the hook, learners explore the concept of changes in matter. First, they make a cake similar to the one made by Alice in the story Alice's Adventure in Wonderland by Lewis Carroll. Next, they let their...

Students watch a demonstration to ascertain why a soda can crushed. They make observations and hypothesize about why a soda can crushed and relate the difference in pressure to its affect on objects around us (soda can). Explanation is...

Learners collect and identify plant species from campus, create a home herbarium, and compare with the plant species from school.

High schoolers collect and record data. They identify sex of butterflies. They make conclusions based on collected data.

Middle schoolers observe and count bird sightings around their schoolyard throughout the school year.

Seventh graders learn about John Kellerman, a youngster who was born with Fetal Alcohol Syndrome. They learn how alcohol and pregnancy doesn't mix.

Students research principles of flight. They design their own paper airplanes and make predictions about the performance of different designs. Students keep track of their findings in an electronic journal.

Using elimination to find the point of intersection of two lines, students learn to solve systems of equation. They graph their solutions and use the TI to verify the solution.

Learners examine how seeds germinate in a culture.  In this germination instructional activity students germinate seeds in gelatin and observe the growth of the plant.

In this voltage, current and resistance worksheet, students answer 21 questions about voltage, current and resistance. They find the current in batteries, they find the voltage in a resistor and they identify the voltage in circuits.
