How do you put something as large as the universe in perspective? Use a series of scale experiments. Classmates collaborate around four experiments to examine the scale of the earth-moon system, our solar system, the Milky Way galaxy,...

Students measure the actual size and distance of the solar system using scale and ratio. They watch and discuss a video, create a distance-scale solar system model, and compare the scale sizes of planets to their actual sizes.

When is a foot not a foot? When you use the length of your own foot to measure distances, of course. To underscore the importance of standardized units of measurement, middle schoolers engage in a series of activities that ask them to...

Students gain an understanding of how the powers of 10 and scientific notation can be used to represent the scale of things in the universe. They relate the number of stars in the universe to the number of grains of sand on Earth's beaches.

Students create scale models of Earth, the Moon, and the distances within the universe. Working in groups, they construct their models of Earth and the Moon on a scale of 50:1 and calculate how far apart to place their models. They...

Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Students assess how algebra, telescopes, space exploration and optics are so important in astronomy. They encounter studies on the Hubble Space Telescope, Hubble Deep Field and how algebra helps to determine the effects of contamination...

Young scholars write letters to organizations, such as United States Geological Society, to find out more about rocks. Students write about a pretend time they found a magic pebble. Young scholars calculate distances to travel to see...

Students examine a message sent from outer space and do their best to interpret its meaning. In this problem solving lesson, students investigate a code sent to them from "outer space." The students collaborate with their classmates to...

Students discover the need for a universal measurement system. They practice using basic metric units in measuring distance and weight.

In this counting up worksheet, students learn strategies to help them solve problems involving change. Students study a number grid and number line to help them count up to make change.

This textbook takes the learner from the basic definition of slope through derivatives, integrals, and vector multivariable calculus. Each section is composed primarily of examples, with theoretical introductions and explanations in...

Sixth graders compare distances between objects in the solar system. They investigate how light years are measured and when using them to measure how distances compare with one another. They write an essay exploring the possibility of...

  Students practice measurement.  In this fractions instructional activity, 6th graders measure volume of a liquid, e.g. 1/5 liter, and learn the vocabulary of fractions (numerator, denominator). Students solve sample problems...

High schoolers describe the different units of measurement. In this space science lesson, students calculate astronomical distances using a scale. They explain the significance of using scientific notation in expressing very small...

Students experience and study how space offers expanding resources for commerce, science, technology and education. They view how advances in space can and do improve life on Earth. Each student views a geological exploration within this...

Students investigate various aspects of the human body  in this imaginative Tree House Detective episode about the biological biosphere. In a series of They take measurements, analyze data, and use technology. The lessons...

Beginning geometers use tiles and grid paper to draw and calculate perimeter and area. Rectangles of different sizes are created and then measured to build understanding. The one-inch grid sheet referenced is attached. 

Is GIS the real manifestation of Harry Potter's Marauders Map? Introduce your class to the history of geographic information systems (GIS), the technology that allows for easy use of spatial information, with a resource that teaches...

Students experience the dynamic skills and processes needed to design the next generation of launch vehicles at NASA. They view how mathematics, science and technology all work together to achieve excellence in human space flights.

Students define area and perimeter. They demonstrate understanding of the concepts concretely, with manipulatives, and describe with words, their strategies and thought processes.

Middle schoolers place a pencil perpendicular to the ground and trace its shadow between 11:30 AM and 12:30 PM. They measure the length of the shadow, periodically over several hours, in either English or Metric units. Using the data,...

Pupils study the beautiful mathematical model unique to our solar system.

Third graders develop questions they have about the solar system. After being read a book, they view and discuss different constellations in the sky. In groups, they are given a piece of butcher paper and glow in the dark crayons in...
