In this reasonable answers learning exercise, students use the problem solving strategy of understand, plan, solve and look back to complete the problems. Students determine if their answers are reasonable by comparing the units.

In this calculus activity, students solve prolbem in which they estimate double integrals by using Riemann sums. The three page activity contains four questions. Answers are not included.

Students take an imaginary hike in two opposite directions along a lake. They view and interpret satellite images and discuss the pros and cons of hydroelectric dams.

In this radiation worksheet, students calculate the total shielding along several specific directions defined by the angles. This worksheet has 3 problems to solve.

Fourth graders practice estimating temperatures. They practice in Celsius and Fahrenheit.

Fourth graders measure cups, quarts, and liters.

Fifth graders use the Celsius and Fahrenheit thermometers to compare temperature readings. They use the Internet to find the temperatures of selected cities. After data is collected for five days, 5th graders graph the temperatures.

Students write and solve equations converting between metric and standard measurement as they travel southeast on the Al-Can Highway.

In this place values worksheet, students write the numbers in the correct boxes to find the distance from Washington, DC to Beijing, China. Students then read the given numbers and fill in the blanks for the place values.

Fourth graders are introduced to how to take measurements in the metric system. After defining new vocabulary, they read a story by Mark Twain about jumping frogs. In groups, they simulate a frog jumping contest in which they made...

Learners search the Internet through a sequence of steps to reach the country of their nationality. They research and collect information about their country.

Learners calculate the amount of greenhouse gases they produce in a given day. Using an equation, they determine the emissions for different sized vehicles and calculate the amount resulting from a family vacation. They create a class...

In this number averages worksheet, students review how to find the average of a given set of numbers. Students then complete three word problems by averaging numbers.

First graders use literature and hands-on activities with maps and globes to explain distance and tools used to measure distance. They select tools to measure various objects in the classroom, then apply those concepts to their map...

Young scholars study their county populations in a multimedia presentation format. For this populations lesson, students work in groups of 3 to research the county populations in their state. Young scholars chart their results in an...

Learners apply estimation strategies and proportional reasoning to determine a scale comparing the planetary bodies to Earth. They convert measurements of time and distance using scientific notation. Both the metric and customary units...

Fourth graders investigate the weight/mass of a number of items using grams, and equivalents. They examine the use of a triple beam balance before massing objects including oil and water. They go over the weights they amassed and weigh...

Learners use a NASA satellite data to contrast amounts of cloud coverage over different climate regions in Africa. They explore how Earth's major air circulations affect global weather patterns, and relate to local weather patterns.

Teams must determine the size of cavern needed to house the citizens of Alabraska to protect them from the asteroid impact. Using scaling properties, teams first determining the number of people that could sleep in a classroom and then...

Bring a set of pre-lab, lab, and post-lab lesson plans on volcanoes to your earth science unit. Sixth graders explore the three types of volcanoes found on Earth, plot the specific locations of these volcanoes on a map, and...

A set of first grade geology lessons focuses on plate tectonics and movement of plate boundaries. During the pre-lab, learners experience three types of plate movement through a kinesthetic demonstration. The lab...

Second graders explore convection currents and how they relate to the movement of tectonic plates. Then, young geologists reconstruct Pangaea with a worksheet and pinpoint plate boundaries on a map...

Third graders examine plate movements and boundaries with a lab that demonstrates how volcanoes and earthquakes are formed. It presents different types of stresses an object can withstand through a hands-on...

For this Jupiter and Io worksheet, students use a diagram of the planet and its moon to find the dimension of the image, the width of the largest feature in the atmosphere of Jupiter, the width of the smallest feature in the atmosphere...
