Looking for a tree-rific addition to your water cycle unit? Teams of young foresters examine the role of transpiration in the water cycle through a week's worth of activities. Pupils analyze how trees take in and transport water during...

Physics is like music—practice makes perfect! Challenge your class using an interactive that builds harmonic skills. The engaging lesson from a playlist exploring sounds and waves revolves around wave behavior in closed-end air columns....

It's hard to envision what 39 billion plastic bottles look like. Brita claims that the US uses that number of plastic bottles each year! If that's not enough to get your attention, figure out how many times 39 billion water bottles can...

All work and no play makes for a boring classroom! Bring back memories by analyzing the patterns of a tether ball. Given the dimensions of the ball, pole, and rope, young scholars must determine how many times the ball will wrap around...

Ever wondered how many pieces of paper a binder clip can hold? Viewers of a short video are about to find out! Given measurement data for three different sized binder clips, learners must develop a method for figuring out how many pieces...

Similar shapes are all about the scale. Given seven problems, pupils use scale factors to determine measurements within similar shapes. While solving the problem, scholars also determine whether two figures are similar and use...

In 2017, more than 15,000 scholars earned college credit based on their AP Physics 2 exam covering lenses, energy, and more. The College Board released the free-response questions, sample answers, and scoring guidelines from that exact...

Knowing the surface area certainly helps when deciding how much paint to buy before a project. Scholars solve for surface area, as well as volume and area, as part of the presentation from Grade 6 Claim 1 Item Slide Shows. Geometric...

Estimating whole number multiplication and division is the focus of an interactive that uses a garden plot with moveable points to answer six questions.

Five questions—multiple-choice, fill in the blank, and discussion—make up an interactive that challenges scholars to mail a teddy bear using the smallest box possible without squishing it. A box with movable sides allows mathematicians...

See calculus to the end. The eBook is the last of a three-volume series covering college-level calculus topics. Scholars begin with parametric equations and polar coordinates before moving to vectors, finally ending with multi-variable...

Take a second look. Form B of the AP® Calculus BC free-response questions allow pupils and teachers to see another set of items. The six questions expand the set of items from the 2011 free-response questions. Form B items include a...

Though the items may be older, they still provide information. Released free-response items from the 2002 AP® Calculus BC exam provide teachers and pupils with information about how topics appear on the exam. Questions come from the AB...

A six-question interactive tasks mathematicians to solve addition and subtraction problems using front-end estimation. Question types consist of multiple-choice and true or false. A set of wooden beams that can be measured using moveable...

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

No need for radians to be mysterious. Scholars use a cardboard cut-out of a unit circle and measure the radius and circumference using a piece of string. They consider the number of radii needed to cover the entire circumference and use...

Make sure it flows smoothly. Pairs research plumbing codes to find the required slope for a sewer line. Using the information, groups answer several questions involving interpreting the slope. Pupils determine the cost of pipe to run a...

In this recognizing customary measurement concepts worksheet, students estimate and measure objects, determine whether measurement of an estimate is sufficient, make lists of objects with specific measurements, and solve word problems....

Students, using wood blocks and model boats, investigate how the shape of an object affects friction it encounters as it is drawn through a towing tank.

Students discover the metric system through video clips and Internet activities. In this measurements lesson, students practice using the units of measure for the metric system and compare them to the less popular English system....

Students examine basic facts about the anaconda. They discuss the length of an anaconda, estimate the length of 33 feet, compare their estimate to the actual length, and decorate the paper snake with colored scales.

Students determine the volume of a rectangular prism. They then maximize and minimize the volume given variable side lengths.  Finally, they factor the volume equation to determine the side lengths.

High schoolers discover properties of parallelograms as they construct a parallelogram using Cabri Jr. They will measure angles and side lengths of their construction and determine the relationship between the diagonals of a...

In this telescope worksheet, students identify the parts of the telescope and use a telescope to observe an object in the room and outside of the room. They measure the length of the inner tube and identify the relationship between the...
