Some planes are just more efficient than others. Young mathematicians use data on the number of seats, airborne speed, flight length, fuel consumption, and operating cost for airplanes to analyze their efficiency. They select and use...

Here's some very interesting circles for your very interested pupils. A performance task requires scholars to sketch a pair of orthogonal circles so the centers are the endpoints of one side of a triangle. They draw an additional circle...

What do Bill Gates and Mark Zuckerberg have in common? They're both billionaires, and neither one has a college degree! Using the website, scholars explore whether having a college education is truly worth the money it costs. They read...

Sometimes the interview process includes negotiating for what you want. Here's an activity that guides job seekers to achieve The Best Alternative to a Negotiated Agreement (BATNA). Participants take on the role of job seekers and...

The strategies civil rights activists Booker T. Washington and W.E.B. Du Bois proposed for blacks to achieve racial progress is the focus of an activity in which class groups identify the strategies as well as the benefits and drawbacks...

Students investigate the importance of fat in the diet. They determine the difference between solid and liquid fat. They examine food labels to identify the ones that contain fat.

Students complete various activities in order to explain that ecosystems are complex and that animal behavior (mainly that of a predator) is not necessarily intentional or bad.

Students read about cats in Borneo and discuss role predators play in controlling population size. They map the interdependencies among species. They read about flux in ecosystems and complete a worksheet.

Students compare models depicting air pressure, They determine which model best conveys the omnidirectional and passive nature of air pressure

Students explore simple circuitry. They compare four models of circuits and explain how each works. Students contrast the cyclic cequential and cyclic simultaneous models using a shower curtain illustration and software simulation.

Students explore simple circuits. Students conduct a variety of experiments to discover their level of conductivity. Students summarize and explain experimental findings. Students are introduced to passive causality.

Students examine models of electrical potential. Students discuss the concept of electrical potential and relational causality. They compare models based on electric potential to those with cyclic simultaneous causality.

Pupils consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how liquids...

Young scholars explore how density changes. Students read an article on density. They observe a ball and ring demonstration and discuss the outcome. Young scholars draw models of the demonstration and explain what happened.

Students explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

High schoolers explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence...

Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...

Pupils discover that density is considered a property and that cutting an object in half does not affect its density. They examine the densities of many common substances and make connections.

Students investigate density and its relationship to air and gas. Students perform experiments to determine if gases have mass. They explore possible ways to figure out the density of gases.

Students review the relationship between mass and volume is constant for a pure substance under standard conditions. They complete mass and volume worksheets using formulas for calculating density.

Students explore models of density; wooden balls and marbles discussing whether they think the volume and mass are the same or different. They then compare the density of a loaf of bread that is squished and one that is not compressed.

High schoolers explore air pressure. They observe what happens when you drink from a straw. Students experiment and create models to prove examine air pressure and vacuums. Shigh schoolers contrast how linear and relational casusal...

Young scholars experiment with a jar, plastic bag and a rubber band to perform a science experiment. Students study the photocopy of Thinking About Relational Causality. Young scholars explore the concept of a pressure-related phenomenon...

Sixth graders study the cosmos and their thoughts and feelings about the universe.  In this cosmic poetry lesson students create a venue where they can "safely" ask questions and discuss ideas.
