Students investigate the effect of weight on normal friction or the friction due to surface roughness. They tell about the effects of contact area that occurs as a result of molecular attraction by looking at data on line graphs.

Students participate in a scavenger hunt and a drawing activity to examine the use of Global Positioning Systems including a handheld GPS receiver for personal navigation. They practice using the GPS receivers while collecting data from...

Middle schoolers analyze graphs to determine relationships between variables and rates of change. They determine the basic concepts about static reaction forces. They determine the slope and equation of a line.

Students explore the observable properties of matter and utilize them in classification. They use a binary classification system to divide objects, then justify their scheme.

Students explore the observable properties of matter. They develop two binary classification systems using concrete objects. based on two different properties of the concrete objects.

Learners perform an experiment with different types of bird eggs to determine what factors make them strong and able to stay on a cliff without rolling off.

Students determine the forces necessary to move a truck on an inclined plane with weight and slope as variables. They identify the cheapest way to transport trash to local garbage disposal sites.

Students investigate variables which may seem to affect the movement of a pendulum, or "swing."They interpret their observations and apply the scientific principles to develop explanations and solve a new problem.

Students develop simple observations. They observe bleeding of colored inks with water, to understand mixtures, and to make generalized inferences from their observations.

Young scholars apply rules to compare and rank the hardness and softness of minerals. They perform a scratch test on four unknown mineral samples, read a bar graph that illustrates the comparative hardness and softness of four named...

Students fill out an anonymous questionaire to explore whether they might have asthma. They then set up a spreadsheet to enter the data, decide on a definition of asthma, and figure out the prevalence of asthma. Pupils simulate what it...

Learners study the concept of negligence. They recognize the difference between civil and criminal law and examine the factors that courts consider when considering if there is a duty and whether it has been breached. They argue either...

Students address a major misconception in astronomy, the understanding of scale. The lesson plan is designed to introduce students to both celestial coordinates and to the first rung on the distance determination ladder, parallax.

Students conduct research on a selected topic, organize the research information, and write a report. They read and discuss the rubric, brainstorm to develop criteria for determining credible sources, complete a KWL chart or web, and...

Students utilize the process of scientific inquiry and technological design to explain thrust, weight, lift and drag in flight. They design an "airplane" to test the "mechanics" of flight. In addition, they brainstorm and sketch a design...

High schoolers determine the specific heat of unknown metals. based on their hypothesis and design proposal. They analyze the findings of the specific heat of the unknown metals. Students complete this by questions, hypothesis,...
