This laboratory consists of two parts. In part A, we will follow Hubble’s method of measuring distances. Using pulsation time periods, we will obtain the absolute magnitude of a Cepheid variable and convert this absolute magnitude into luminosity which will, in turn, give us the distance. In Part B, we will use spectral shift (the Doppler effect) to determine the Hubble Constant.  --------------------------------------- Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

Students learn how engineers gather data and model motion using vectors. They learn about using motion-tracking tools to observe, record, and analyze vectors associated with the motion of their own bodies. They do this qualitatively and quantitatively by analyzing several examples of their own body motion. As a final presentation, student teams act as engineering consultants and propose the use of (free) ARK Mirror technology to help sports teams evaluate body mechanics. A pre/post quiz is provided.

Think science has all the answers? Think again. This course will use real, authentic data to explore and investigate modern controversies in Earth Sciences. Use tide gauge records to understand how countries around the world attempt to protect themselves from tsunami events. Process seismic data to predict earthquake recurrence in the New Madrid seismic zone, right here in the breadbasket of the US. Sort through the millions of years of the geologic timeline to shed some light on what actually did, and did not, kill the dinosaurs. Finally, use global atmospheric data to understand how misrepresentation of data can be used to paint a distorted view of past, present, and future climate.

Students learn about factors that engineers take into consideration when designing buildings for earthquake-prone regions. Using online resources and simulations available through the Earthquakes Living Lab, students explore the consequences of subsurface ground type and building height on seismic destruction. Working in pairs, students think like engineers to apply what they have learned to sketches of their own building designs intended to withstand strong-magnitude earthquakes. A worksheet serves as a student guide for the activity.

Students learn how engineers characterize earthquakes through seismic data. Then, acting as engineers, they use real-world seismograph data and a tutorial/simulation accessed through the Earthquakes Living Lab to locate earthquake epicenters via triangulation and determine earthquake magnitudes. Student pairs examine seismic waves, S waves and P waves recorded on seismograms, measuring the key S-P interval. Students then determine the maximum S wave amplitudes in order to determine earthquake magnitude, a measure of the amount of energy released. Students consider how engineers might use and implement seismic data in their design work. A worksheet serves as a student guide for the activity.

Students study how geology relates to the frequency of large-magnitude earthquakes in Japan. Using the online resources provided through the Earthquakes Living Lab, students investigate reasons why large earthquakes occur in this region, drawing conclusions from tectonic plate structures and the locations of fault lines. Working in pairs, students explore the 1995 Kobe earthquake, why it happened and the destruction it caused. Students also think like engineers to predict where other earthquakes are likely to occur and what precautions might be taken. A worksheet serves as a student guide for the activity.

Students examine the effects of geology on earthquake magnitudes and how engineers anticipate and prepare for these effects. Using information provided through the Earthquakes Living Lab interface, students investigate how geology, specifically soil type, can amplify the magnitude of earthquakes and their consequences. Students look in-depth at the historical 1906 San Francisco earthquake and its destruction thorough photographs and data. They compare the 1906 California earthquake to another historical earthquake in Kobe, Japan, looking at the geological differences and impacts in the two regions, and learning how engineers, geologists and seismologists work to predict earthquakes and minimize calamity. A worksheet serves as a student guide for the activity.

Students learn the two main methods to measure earthquakes, the Richter Scale and the Mercalli Scale. They make a model of a seismograph a measuring device that records an earthquake on a seismogram. Students also investigate which structural designs are most likely to survive an earthquake. And, they illustrate an informational guide to the Mercalli Scale.

This book introduces students to some of the most unusual places in our galaxy outside of our solar system. Answering the question, "How many stars are in the sky?" introduces students to basic counting, tallying, and grouping techniques, as well as allowing for the use of simple proportions.

Students learn about video motion capture technology, becoming familiar with concepts such as vector components, magnitudes and directions, position, velocity, and acceleration. They use a (free) classroom data collection and processing tool—the ARK Mirror—to visualize and record 3-D motion. The Augmented Reality Kinematics (ARK) Mirror software collects data via a motion detector. Using an Orbbec Astra Pro 3D camera or Microsoft Kinect (see note below), students can visualize and record a robust set of data and interpret them using statistical and graphical methods. This lesson introduces students to just one possible application of the ARK Mirror software—in the context of a high school physics class. Note: The ARK Mirror is ported to operate on an Orbbec platform. It may also be used with a Microsoft Kinect, although that Microsoft hardware has been discontinued. Refer to the Using ARK Mirror and Microsoft Kinect attachment for how to use the ARK MIrror software with Microsoft Kinect.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye. Learners will be surprised to discover the range of sizes in the microscopic world. This activity can be followed up with a second activity, "What's in a microbe?", located on page 3 in the same resource.
