Here is a comprehensive method for assessing chemistry learners' knowledge; have them approach two laboratory problems, plan their methods of solving each, and then actually carry out the experiments to find the answers. Both the...

Learners will shout "Eureka!" in this quick but deep activity replicating the famous bathtub experiment of Archimedes. Given the scenario of a king with a suspected fake crown, young investigators develop formulas using density to...

Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of...

Compounding is dividing units. Pupils practice using compound measures such as units for speed and density to solve problems that range from straightforward speed problems to those requiring conversions. The last few items challenge...

Graphs, functions, symbols, and more! Use these strategies to model everything from the flow of a river to the number of cars passing a toll booth. Presented differently but solved similarly, learners consider five different scenarios...

Plan the way to school. Given a map of a school district, class members portray a transportation consultant hired to develop a bus transportation plan that will pick up the eligible riders and get them to school. The plan must contain...

A remarkably high number of scholars passed the AP Biology exam in 2016 with over 61 percent earning college credit. The College Board released the entire free-response section for future scholars to study. After answering the eight...

Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...

Let the resource take center stage in a lesson on population density. Scholars use provided historical data on the center of the US population to see how it shifted over time. They plot the data on a spreadsheet to look the speed of its...

In this assessment task, learners determine whether a crown with given information is composed of pure gold. The task expects algebraic and numerical solution methods, so unlike Archimedes, no bathtub is necessary.

Use this resource to present your number crunchers with how to write a constraint equation and to determine viable solutions. The price of an object limits the amount that can be purchased. The speed at which you walk limits the number...

This is a list of 83 problems/exercises to solve based on the content in Chapter ll: Fluid Statics from the AP Physics online text.

Students must determine the density of a rock based on the change in tension in the supporting string when the rock is lowered into a fluid.

Students must determine the density of a fluid based on the fluid levels in a u-tube.

Solve problems concerning real-world situations using your knowledge of volume, surface area, and density.

Students must find out the strength of the gravitational force between two spherical objects based on the size, density and distance between centers.
