Using the planetarium program Stellarium, you will display the evening sky just after sunset for the date and location of your birthplace.  You will determine the times of the sunrise, sunset, and moon rise on your birthday, note the phase of the moon, and observe planetary positions and visibility.   ---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

In 1610, Galileo made the first telescopic survey of the Milky Way and discovered that it is composed of a multitude of individual stars. Today, we know that the Milky Way comprises our view inward of the huge cosmic pinwheel that we call the Milky Way Galaxy and that is our home. Moreover, our Galaxy is now recognized as just one galaxy among many billions of other galaxies in the cosmos.---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

Growing up at a time when the Hubble Space Telescope orbits above our heads and giant telescopes are springing up on the great mountaintops of the world, you may be surprised to learn that we were not sure about the existence of other galaxies for a very long time. The very idea that other galaxies exist used to be controversial. Even into the 1920s, many astronomers thought the Milky Way encompassed all that exists in the universe. The evidence found in 1924 that meant our Galaxy is not alone was one of the great scientific discoveries of the twentieth century.---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

This activity will focus on Kepler's Law which concerns planetary motion.---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

Edwin Hubble examined the spectra of many galaxies, looking for the red (longer wavelengths) or blue (shorter wavelengths) shifts in the spectra, indicating relative motion. To his surprise, not only did all of the galaxies appear to be moving, but all were moving away from us, no matter the direction of the galaxy. In addition, he found most galaxies exhibited a redshift, and the redshift was larger the further it was from our galaxy.Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

Galileo, in 1612, demonstrated that the Sun rotates on its axis with a rotation period of approximately one month. Our star turns in a west-to-east direction, like the orbital motions of the planets. The Sun, however, is a gas and does not have to rotate rigidly, the way a solid body like Earth does. Modern observations show that the Sun’s rotation speed varies according to latitude; that is, it’s different as you go north or south of the Sun’s equator.  Between 1826 and 1850, Heinrich Schwabe, a German pharmacist and amateur astronomer kept daily records of the number of sunspots. What he was looking for was a planet inside the orbit of Mercury, which he hoped to find by observing its dark silhouette as it passed between the Sun and Earth. Unfortunately, he failed to find the hoped-for planet, but his diligence paid off with an even more important discovery: the sunspot cycle. He found that the number of sunspots varied systematically, in cycles about a decade long. In this laboratory, you will engage in tracking the Sun like Galileo and Schwabe during a six-day cycle and then do a simple calculation of the rotational period of our sun.---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

Given the spectral classification of a distant giant star, you will use the H-R diagram to estimate its absolute magnitude and luminosity. From the distance modulus formula, you will estimate its distance via spectroscopic parallax. From the spectral type, you will estimate its surface temperature and then use the luminosity formula to estimate the diameter of your giant star.---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

A plot of luminosity vs. time is a ‘light curve’. In this laboratory, we will use a light curve to determine the diameter of two stars in a binary system.  --------------------------------------- Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

This laboratory measures the parallax shift of the Delta Leonis and uses a Spectral Classification Table to calculate the radius of this star from its temperature.---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

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".

In Part B, we will use a Python computer coding script to obtain a spectral redshift of a galaxy (M100). From this redshift, we will use the Doppler formula to find a recession speed. From this speed, we will apply Hubble’s Law to obtain the Hubble Constant.---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".

Our class is part of Arts and Sciences Undergraduate Research Experience (ASURE) at Indiana University Bloomington. This program, which is part of the College of Arts and Sciences, includes a two-semester lab experience where students design and conduct their own authentic research projects. All of the projects described in this eBook were designed and carried out by small groups of students in their first through second year of college as part of their course work in the ASURE Immune Response and Behavior Lab. The ASURE class of 2019-2020 certainly faced some unique challenges. In the spring of 2020, we were abruptly sent home to continue our coursework remotely. This interruption reduced the students’ time to collect data in the lab, but gave them the opportunity to learn R and other data analysis skills. In the fall of 2020, all of the students were able to return to campus and continue work on their projects, though there were several interruptions as students were forced to isolate and/or quarantine. Nevertheless, the students were very dedicated and persisted in their work, which is evident in their final projects.

Welcome to the TIES therapist onboarding resource! These resources are available to help standardize school-based therapist training throughout the state of OR while also allowing individual school districts and ESDs to remix each resource to suit the needs of their region. By doing so, we aim to ensure continuity of training and services throughout the state.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"The transcription factor ATF5 plays a vital role in the formation of several cancers, including breast, lung, ovarian, pancreatic, rectal, and liver cancer. But ATF5’s function in esophageal cancer—one of the most common forms of cancer worldwide—remains unclear. To find out, researchers monitored the activity of ATF5 in esophageal cancer tissues. Much like in other cancers, ATF5 was upregulated in esophageal cancer tissues cultured in the lab, and ATF5 overexpression promoted the proliferation, migration, and invasiveness of esophageal cancer cells. Silencing ATF5, however, inhibited these abilities. In fact, in mice, silencing ATF5 hampered tumor growth. ATF5’s role as a lever that triggers tumor growth is believed to occur through an interaction with HIF1, a protein complex also known to promote the growth and spread of tumors. These findings suggest that the known anti-cancer effects of silencing ATF5 might also be powerful against esophageal cancer..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this module we will provide a comprehensive description of the legal landscape of the assistive technology locally and on an international level as well as best practices.

This YouTube channel features a series of videos recorded in 2014 by Hayley Smith, a university student who studied in Jordan in 2014. Before her trip to Jordan, Smith conducted a survey of K-12 Arabic teachers, asking them to recommend topics for the videos that would be helpful in teaching Arabic. The result is this series of videos, arranged in playlists that follow each individual participant through different scenarios and questions. The short clips are wonderful for exposing Arabic students to colloquial Arabic, spoken in daily situations and at a natural pace. This is a great way for students to see what young Jordanians are like, and to learn about their interests, their studies, and their relationships. Also on this channel are other playlists of popular videos, such as Arab Idol, which have been edited down for classroom use.
