In this Cyberchase video segment, the CyberSquad helps resolve a dispute about the squares on the Gollywood Walk of Fame.

This is a set of three, one-page problems about the size and area of solar panels used to generate power. Learners will calculate area fractions to compare the sizes and distances of Jupiter's moons. Options are presented so that students may learn about the Juno mission through a NASA press release or about how solar energy is used by various NASA satellites and technology by viewing a NASA eClips video [3 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.

This is an activity about coronal mass ejections. Learners will calculate the velocity and acceleration of a coronal mass ejection, or CME, based on its position in a series of images from the Large-Angle Spectrometric Coronograph (LASCO) instrument on NASA's Solar and Heliospheric Observatory (SOHO) spacecraft. This is Activity 2 of a larger resource, Exploring the Sun. The NASA spacecraft missions represented by this material include SOHO, TRACE, STEREO, Hinode, and SDO.

This lesson is designed to teach students to measure angles with a protractor. The student will be taught how to read the protractor correctly by using either the top or bottom set of numbers. The lesson will reinforce classifying angles as acute, right, and obtuse. The student will sketch angles given a specified measure. This lesson results from the ALEX Resource Gap Project.

Students learn how volume, viscosity and slope are factors that affect the surface area that lava covers. Using clear transparency grids and liquid soap, students conduct experiments, make measurements and collect data. They also brainstorm possible solutions to lava flow problems as if they were geochemical engineers, and come to understand how the properties of lava are applicable to other liquids.

In this Cyberchase video segment, the CyberSquad must measure the length of the rope that will lower Digit from the ceiling to remove the voice box from a statue of Hacker.

This model-eliciting activity challenges students to operationally define a construct (study effectiveness). Students are given a survey to review that rates different aspects of study behaviors. They are then given a set of data for a few students and asked to use their scores to determine an index of study effectiveness. After determining a method, they are then asked to use this index to put five students in rank order according to their scores on study effectiveness. Students write a report explaining the method they used to determine these scores and how they produced their ratings.

This set of assignments exposes students to statistics and data pertaining to economic wellbeing over time across racial (black-white) categories in the U.S.

This activity is a lab investigation where students gather data about the masses of various solid objects found in a classroom. The students graph their data, compare their data, and draw conclusions about what kinds of materials contain more matter than others.

This activity is an guided inquiry based lesson where students measure and graph data on a two-coordinate graph the growth of a toy animal submerged in water over a period of time.

This goal of this task is to give students familiarity using the formula for the area of a circle while also addressing measurement error.

After conducting the associated activity, students are introduced to the material behavior of elastic solids. Engineering stress and strain are defined and their importance in designing devices and systems is explained. How engineers measure, calculate and interpret properties of elastic materials is addressed. Students calculate stress, strain and modulus of elasticity, and learn about the typical engineering stress-strain diagram (graph) of an elastic material.

In this activity, we will explore how the dosage and frequency of a medicine taken affect the amount of medicine present in the blood.

This task addresses the first part of standard F-BF.3: ŇIdentify the effect on the graph of replacing f(x) by f(x)+k, kf(x), f(kx), and f(x+k) for specific values of k (both positive and negative).Ó Here, students are required to understand the effect of replacing x with x+k, but this task can also be modified to test or teach function-building skills involving f(x)+k, kf(x), and f(kx) in a similar manner.

This is a problem-based learning adventure game that engages the player in the role of scientist, historian, and detective. At the beginning, the student is presented with a problem that must be solved. During the mission, students conduct field and laboratory investigations with the aid of the MedMyst characters. This mission can be played within one class period (approximately 30 to 45 minutes) and the knowledge gained from this mission will help students understand how infectious diseases are spread. This mission covers vectors, malaria, history of malaria, and immune system. Each mission is a self-contained problem and may be played without reliance on the other missions. Also available in Spanish.

Meiosis is the process by which gametes (eggs and sperm) are made. Gametes have only one set of chromosomes. Therefore, meiosis involves a reduction in the amount of genetic material. Each gamete has only half the chromosomes of the original germ cell. Explore meiosis with a computer model of dragons. Run meiosis, inspect the chromosomes, then choose gametes to fertilize. Predict the results of the dragon offspring and try to make a dragon without legs. Learn why all siblings do not look alike.
