Students learn about an important characteristic of lines: their slopes. Slope can be determined either in graphical or algebraic form. Slope can also be described as positive, negative, zero or undefined. Students get an explanation of when and how these different types of slope occur. Finally, they learn how slope relates to parallel and perpendicular lines. When two lines are parallel, they have the same slope and when they are perpendicular their slopes are negative reciprocals of one another.

In this biology lab extension, student will have already collected leaves from the playground and surrounding school areas and sorted them into categories according to leaf properties. Students will use the leave classifications/ sorts to graph the properties of the leaves.

Rebecca Davis sets up a coordinate plane on the floor of her classroom. Groups of 3 or 4 students are assigned equations in slope-intercept form and graph them using their bodies on the giant coordinate plane. As extensions, Ms. Davis changes the slope or y-intercept of the original equation and makes the activity into a race.

In this activity, students will explore the concept of binary fission, generation time, and bacterial growth curves, with an emphasis on the log phase. Students will use semi-log graphs and linear graphs to plot bacterial cell growth.

Students are introduced to different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction grating acts like a prism, bending light into its component colors.

Students are introduced to concepts of hypothesis testing using elementary hypothesis tests, t-tests, and p-values as they compare a given fish population for methylmercury levels (using real and hypothetical data) against real-world mercury standards.

Students are introduced to concepts of sampling distributions and hypothesis testing using a simulation applet, elementary hypothesis tests, t-tests, and p-values as they compare a given fish population for methylmercury levels (using real and hypothetical data) against real-world mercury standards.

This activity is designed to support a variety of STEM concepts: scientific method, making predictions, gathering and analyzing data, and developing conclusions based on experimentation. This activity draws on active student engagement, and is useful in many STEM content areas.

In a multi-week experiment, student groups gather data from the photobioreactors that they build to investigate growth conditions that make algae thrive best. Using plastic soda bottles, pond water and fish tank aerators, they vary the amount of carbon dioxide (or nutrients or sunlight, as an extension) available to the microalgae. They compare growth in aerated vs. non-aerated conditions. They measure growth by comparing the color of their algae cultures in the bottles to a color indicator scale. Then they graph and analyze the collected data to see which had the fastest growth. Students learn how plants biorecycle carbon dioxide into organic carbon (part of the carbon cycle) and how engineers apply their understanding of this process to maximize biofuel production.

This textbook provides an introduction to the MATLAB programming language for first-year mechanical engineering students enrolled in ME 160. Designed to follow the content taught in class, this book provides a supplement to in-class learning that is presented at a level that is understandable to a student with no experience coding before coming to Iowa State University.

SYNOPSIS: In this lesson, students reflect on their personal energy use, make a bar graph to analyze data from the class, and create a conservation poster for display.

SCIENTIST NOTES: This lesson is suitable to build the capacity of students to understand energy sources and what they can power, to compute and audit their daily energy consumption, to share their energy footprint in group activities, and to raise awareness on energy consumption to a wide audience by creating a conservation poster. This lesson has passed our science review process and is recommended for classroom use.

POSITIVES:
-This lesson includes using a spreadsheet to create a bar graph. This may be the first time students learn this skill.
-Creating a conservation poster is a great way for students to feel empowered to take immediate climate action.

ADDITIONAL PREREQUISITES:
-This is lesson 2 of 6 in our 3rd-5th grade Renewable Energy unit.
-When you are collecting data for the spreadsheets and graphs, some students may respond that they spent 1,440 minutes using energy (which is the total amount of minutes in a day) due to use of electricity for refrigerators or the heating and cooling of their homes. Although true, having multiple data points of 1,440 minutes is not useful. Have them come up with a lower estimate.

DIFFERENTIATION:
-Some students may have difficulty with data entry when adding numbers to their spreadsheet. It may be best to create groups of students so they can check each other's progress to make sure it is correct.
-It may be best to allow students to create conservation posters individually or with a partner.
-Some students may want to create conservation posters using digital tools like Canva or Adobe Spark.

Kindergartners measure each other's height using large building blocks, then visit a 2nd and a 4th grade class to measure those students. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, how height changes as children get older. The introduction to graphing provides an important foundation for both creating and interpreting graphs in future years.

Students will use ratios to demonstrate the connections between proportional relationships, lines, and linear equations. Students will solve problems using a cooperative, kinesthetic activity in which they will create a ratio table, then graph proportional relationships with their bodies to demonstrate that the ratio (or rate) is the slope that will always pass through the origin.

In this three lesson series, students will analyze the effects of the drought in California. Students will analyze rainfall data and graph the annual rainfall for California. Students will understand the water cycle and explain how a drought affects the water cycle. Students will research methods to conserve water and write a persuasive argument.

The task is an introduction to the graphing of exponential functions. The first part asks students to use technology to experiment with the two parameters defining an exponential function, with little guidance. Since it is important for the second part, teachers should encourage students to try a wide range of values, and in particular, values of b both less than and greater than 1. The task includes a Desmos app, in which students can make use of sliders to more viscerally see the effect of changing a and b separately.

Gait analysis is the study of human motion that can be utilized as biometric information or identification, for medical diagnostics or for comparative biomechanics. In this activity, students observe walking human subjects and then discuss parameters that could be used to characterize walking gaits. They use accelerometers to collect and graph acceleration vs. time data that can help in gait analysis—all part of practicing the engineering data analysis process. Students complete this activity before learning the material presented in the associated lesson.

This article discusses how the study of weather can meet the NCTM Data Analysis and Probability standard. Links to lessons for grades K-2 and 3-5 are provided.

6.0002 is the continuation of 6.0001 Introduction to Computer Science and Programming in Python and is intended for students with little or no programming experience. It aims to provide students with an understanding of the role computation can play in solving problems and to help students, regardless of their major, feel justifiably confident of their ability to write small programs that allow them to accomplish useful goals. The class uses the Python 3.5 programming language.
