Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Fire in the hole! Thrill your classes as they see what it's like to fire a cannon ball. Scholars practice aiming a cannon ball by altering first the firing angle, then the velocity, and finally both simultaneously. Can they discover the...

From windows that tint themselves to OLED technology, electrochromic polymers are redefining our ideas about conducting materials! Introduce your chemistry class to the emerging trend with an exciting lab activity. Budding materials...

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Students define and explain the basic concepts of experimental design.  In this scientific method lesson students complete a hands on activity, develop and present proposals to test their explanations. 

Young scholars explore the scientific method. For this science lesson, students create and conduct a science investigation for the science fair.

Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.

Middle schoolers examine the growth of marigolds in a greenhouse environment. They chart data in spreadsheets showing plant growth over time and under a number of conditions. They record measures of plant height and greenhouse temperature.

Students examine how to design and implement experiments.  In this paper towel experiment lesson students test the strength of paper towels. 

Students address the idea that human beings live within the world' ecosystems. They discuss how humans modify ecosystems as a result of population growth, technology, and consumption. Students discuss how the human destruction of...

Students demonstrate how to create and test a hypothesis. They design an experiment and set up a variable, experimental group and control group.

Students investigate and study logarithmic equations. In this precalculus lesson, students analyze the data behind the function. They define each graph as positive, negative or no correlation. They find the line of best fit.

Students are given a problem or hypothesis, they can create a relevant experiment using the steps to the scientific method. They collect quantitative and qualitative observations in scientific experiments. Students identify the...

Pupils solve problems using systems of equations. In this algebra lesson, students find the point of intersection of two lines. They use the TI Calculator to graph and see the point of intersection.

Students explore the states of water. In this physical science instructional activity, students use ice and dry ice to observe the changes in the state of matter. Students record the results.

Ninth graders explain how scientists set up investigations. In this scientific process activity, 9th graders review the principles of the scientific method and use these skills to answer an open-ended question about how to set up a...

Twelfth graders look at local speed limits and traffic controls and see if they are reasonable. They plot the displacement and time to represent velocity, develop a plan for improving the current system, and organize experimental...

Students analyze the stellar magnitude scale. In this stellar magnitude lesson, students examine the stellar magnitude scale. Students predict the Sun's magnitude from various planets.

Students explore their weight on other planets. In this science lesson, students view a presentation about the other planets and complete a worksheet in which they make predictions about their weight on the moon and other planets.

Students study the scientific method and explore how to design an experiment.  In this investigative lesson students explore and hypothesis an experiment then carry it out to find the results. 

Students define normal distribution as it relates to the bell curve. In this statistics activity, students use the central tendencies of mean, median and mode to solve problems. They plot their data and draw conclusion from the graphs.

Students calculate the normal distribution. In this statistics lesson, students use the normal distribution to estimate binomial distributions. They define when to use NP and n(1-p) to make approximations.

Pupils will investigate trigonometric equations. In this trigonometry lesson, they explore solving equations using a TI-83 calculator and solve trigonometric equations by graphing each side of the equation as a function and locating the...

Students explore linear relationships. In this sixth through eighth grade mathematics instructional activity, students explore the symbolic representation of verbal descriptions of mathematical rules defining the relationship between two...
