Ice core data allow students to explore a number of patterns while learning that researchers need to gather and interpret evidence to understand Earth's past. Students will explore core data collected in Western Greenland that document a few decades of Earth's atmosphere. Students are challenged to identify patterns and then use those patterns and background information to answer a few key questions. The data include measurements of temperature, dust, and atmospheric gases.
Downloadable files are provided for those who intend to run the activity in person. For those running the activity with an online or virtual class, a separate page includes all of the necessary information for students to complete the activity, including an interactive graph and background readings. Support videos are provided.

Students will examine historical photographs and a data table related to 19th-century industrialization and child labor. They will observe and analyze the primary sources and ask questions. This activity could be used near the beginning of a unit on industrialization or the Progressives.

Through the use of the 5E instructional model, students discover the value of using color maps to visualize data. The activity requires students to create a color map of the ozone hole from Dobson data values derived from the Aura satellite. Students then interpret that map and compare and evaluate different color scales.

This simulation allows you to use a slider to see how positive and negative integers add on a number line.

Through this lesson and its series of hands-on mini-activities, students answer the question: How can we investigate and measure the inside of an object or its structure if we cannot take it apart? Unlike the destructive nuclear weapon test (!), nondestructive evaluation (NDE) methods are able to accomplish this. After an introductory slide presentation, small groups rotate through five mini-activity stations: 1) applying Maxwell’s equations, 2) generating currents, 3) creating magnetic fields, 4) solving a system of equations, and 5) understanding why the finite element method (FEM) is important. Through the short experiments, students become familiar with the science and physics being used and make the mathematical connections. They explore components of NDE and see how engineers find unseen flaws and cracks in materials that make aircraft. A pre/post quiz, slide presentation and worksheet are included.

Each page of this activity has a CODAP doc for recording data from sensors. This can be used for ad hoc experimentation or just messing around with sensors to learn how to use them. If not using sensors, the sensor interactive can be minimized and moved out of the way.

This Immersion Unit provides a coherent series of lessons designed to guide students in developing deep conceptual understanding that is aligned with the standards, key science concepts, and essential features of classroom inquiry (as defined by the National Science Education Standards).  Unit Overarching Concepts Populations of living organisms change or stay the same over time as a result of the interactions between the genetic variations that are expressed by the individuals in the populations and the environment in which the population lives. Science knowledge advances through inquiry. Unit Supporting Concepts Individual organisms with certain variations of traits (adaptations) are more likely than others to survive and reproduce successfully.When environmental conditions change it can affect the survival of both individual organisms and entire species. Natural selection determines the differential survival of groups of organisms. A small advantage in escaping a predator, resisting a drug, etc. can lead to the spread of a trait in a modest number of generations. Mutations are a source of variation in an individual’s genotype, and it can result in a change in phenotype––good or bad. Scientific progress is made by asking meaningful questions and conducting careful investigations, using appropriate tools and technology to perform tests, collect data, analyze relationships, and display data. No matter how well one scientific explanation fits observations, a new explanation might fit them just as well or better, or might fit a wider range of observations. In science, the testing, revising, and occasional discarding of explanations, new and old, never ends. This unit was developed through the large Math and Science Partnership project called System-wide Change for All Learners and Educators (SCALE), involving a collaboration among Los Angeles School District educators, California State University science and education faculty, and UW-Madison SCALE staff.

Using a map showing the horizontal velocities of GPS stations in the Plate Boundary Observatory and other GPS networks in Alaska and Western United States, students are able to describe the motions in different regions by interpreting the vectors resulting from long-term high-precision Global Positioning System (GPS) data.

Students will explore time series plots and raw data to understand the role of sea surface temperature increases on arctic ice melt. This is part three of a four-part activity on polar science. The activity builds on the knowledge gained in Using Data and Images to Understand Albedo (part 2). Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. Information is provided on data access using the NOAA Earth System Research Laboratory Web site. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster.

Learn about exponential decay in real-world situations. Problems involve the application of depreciation of an asset and radioactive decay. Learn to apply exponential decay equations and interpret graphs. This is the last of three activities for teaching and learning about exponential functions in algebra: Graphing Exponential Equations; Exponential Growth; and Exponential Decay.

Context based exponential growth and decay questions.

(This is used as a test of OER)

In this task students prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals.

Learn about exponential growth in real-world situations. Problems involve the application of compound interest and exponential population growth. This is the second of three activities for teaching and learning about exponential functions in algebra: Graphing Exponential Equations, Exponential Growth and Exponential Decay.

This problem illustrates how an exponentially increasing quantity eventually surpasses a linearly increasing quantity.

In this task students observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function.

This problem shows that an exponential function takes larger values than a cubic polynomial function provided the input is sufficiently large.

This seminar will teach you about special types of exponential functions that model growth and decay. You will learn how to distinguish between the two types of functions and also what types of situations are represented by each. You will learn why the specific values in each type of function have the effect on them that they do, and why the terms “growth” and “decay” are appropriate to describe the types of functions. You will see examples of each type of function and why the specific numbers in the functions have the effects of either making the values grow or decay.  StandardsCC.2.1.HS.F.1 Apply and extend the properties of exponents to solve problems with rational exponents.

The purpose of this task is twofold: first using technology to study the behavior of some exponential and logarithmic graphs and secondly to manipulate some explicit logarithmic and exponential expressions. Although not asked in the task body, the teacher may wish to prompt students to explain why the two graphs behave as they do as the base b varies: that is, a larger value of b between 1 and 2 makes the exponential graph grow faster and the logarithmic graph grow more slowly as x increases.

The task provides a reasonably straight-forward introduction to interpreting the parameters of an exponential function in terms of a modeling context. In general, an exponential function f(t)=ab^t has two parameters. The parameter a is interpreted as the starting value (when t represents time), and b represents the growth rate -- the amount the quantity is multiplied by each time the value of t is incremented by 1.
