Fourth graders plan a picnic using weather data. Using accumulated weather data from various sources, they create a graph of the weather conditions in their region for a given period of time. Students interpret this data to predict the...

Students discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl reasoning to...

Students use an electronic data-collection device to model the sound produced by a guitar string. They identify the graph of a periodic situation and use the graph to determine the period and frequency of sound waves.

Students examine animal reproduction by interpreting data and making arguments and then create their own graphs to explore relationships of organ systems. This instructional activity includes an individual worksheet and a reflective...

Students analyze cancer data represented in graphs and charts. They describe the changes in cell structure and function as the result of cancer. They also examine phenomenas that are believed to cause cancer.

Learners survey and dissect as many fish as possible. They count nematodes, cestodes and crustaceans on the fish, fill out autopsy reports, and transfer data to a chalkboard data table. Students graph the results of the entire class...

Students determine the rate of seismicity by determining the frequency of aftershocks following a major earthquake. They incorporate the use of the Internet, Excel 2000, a map of their area with latitude and longitude markers, and paper...

Students measure a set of Russian dolls using the metric system. In this measurement lesson plan, students identify certain relationships between sets of measurements by measuring a set of Russian dolls and presenting their findings to...

Students count nematodes, cestodes and crustaceans on approximately one-hundred and fifty fish. They fill out autopsy reports for external and internal parasites then complete and discuss guide questions to make inferences about parasite...

In this permutations worksheet, 6th graders solve and complete 5 different types of problems. First, they write a simple conceptual art plan with no more than 3 instructions. Then, students use graph paper and a pencil to draw a plan....

Students examine the temperature flucuations on the Earth. After defining new vocabulary, they identify the flucuations of the Earth on a map. As a class, they develop a hypotheis on the temperature variation by examining the data.

Students are introduced to the software program WorldWatcher. In groups, they discover the temperature variations throughout the world and color a map according to the temperatures. They also practice using visualization to communicate...

Young scholars manipulate a ball and explore quadratic functions. In this algebra lesson, students analyze the graph of a quadratic function. They identify quadratic properties.

Students explore the different variables that affect surface temperature. They study how temperatures can vary widely within close proximity due to variables such as surface, directness of sunlight, and distance from buildings.

Students state the general rule for a practical situation. They describe a continuing pattern. They use toothpicks to help visualize the problem and answer it correctly.

High schoolers experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...

Ninth graders gain an understanding of Chaos Theory that exists in one's everyday environment.

The student will use a variety of methods inculding tables, equations and graphs to find the constant of variation and missing values when given a relationship that varies directly.

Students will use this activity for the following Algebra concepts: Review of Direct Variation; Properties of direct variations; Finding the constant of variations from data sets; Find missing values in data sets both numerically and...

[Free Registration/Login may be required to access all resource tools.] Students will write, graph, and solve direct variation models for real-world problems. Students examine guided notes, review guided practice, study vocabulary, watch...

[Free Registration/Login may be required to access all resource tools.] This lesson shows you have to determine if a set of data varies directly.

The discussion examines direct variation. Students learn about the math concept through definitions and sample exercises.

Students learn about four forms of equations: direct variation, slope-intercept form, standard form and point-slope form. They graph and complete problem sets for each, converting from one form of equation to another, and learning the...

This comprehensive study guide highlights the main terms and formulas needed to understand graphs of rational functions. Examples are included.
