Questions: Who are you? (Who is he? Who is she? What is it?)

 Answers: I am _____. (She is ____. He is ____. It is a/an ____.) 

Key words: I, she, he, it, am, name,  owl, one, two, three, verbs: love walk,

PREPARE TO WATCH 

Get students’ attention Here are some ideas to introduce the lesson points. 

See the How-to Guide for more ways to do this.

 • Introduce key words and questions: Who? Who are you? Who am I?

 • Bring a puppet, picture, or stuffed animal to class. Ask: “Who is this/he/she?” Students can give names and practice repeating the question and answer.

 • Show pictures of famous people or characters you think students may know and ask, “Who is he/she?”

 • Say words that rhyme with who: hoo, moo, zoo Connect to students’ experiences This can be done in native language or English.

 • Tell students the goals for the lesson. Then ask (choose as needed):

 • “How do you introduce yourself in English? In your native language?”

 • “Where do you like to take walks?” (in the city, in the woods, in your neighborhood…)

 • “How do you feel when you walk outside?”

LESSON 1 WELCOME!

Introduce the Lesson 

Topic Explain the story of the course: 

Say, “Anna is moving to a new city, Washington, D.C. She will learn many new things about the city, and you will learn with her. 

In the first lesson, she is meeting her new neighbors.” Ask students to share stories (in native languages, if possible) about when they moved to a new place.

 Present the Conversation 

Tell students that the video will show Anna going to her new apartment. She meets new people there. 

Play the main video. When the speakers say, “Listen” and “Speak” have students repeat and respond. 

DÍA 1

Ask students to act out the conversation with different students two or more times. 

They should use their own names (rather than Anna and Pete). 

This is a good chance for students who are in a new class to get to know each other’s names.

 Learning Strategy Ask students to set a goal for learning English.

 Ask, “What do you want to do in English after studying for three months?” It is best to set a short-term and small goal.

 Remind them to focus on this goal as they study. 

Scientists Learn More about Black Hole at Center of Our Galaxy

Scientists Learn More about Black Hole at Center of Our Galaxy

 Researchers recently announced that they have found qualities of the main black hole in our Milky Way Galaxy that they did not know about before. 

 Black holes are very massive objects with gravity so strong that even light cannot escape them. 

 The space scientists said they found a strong and organized magnetic field around the black hole called Sagittarius A*. It is at the center of our galaxy 26,000 light years away. 

 Activity at the edge of the black hole is believed to have created the magnetic field. It is similar to activity surrounding the only other black hole ever imaged. That one is at the center of a nearby galaxy commonly called M87. 

 The researchers wondered if their finding suggests that strong magnetic fields might be a quality common to all black holes. 

 Black holes and jets 

 The magnetic field around the M87 black hole, called M87*, causes it to launch powerful jets of material into space, the researchers said. They added that while such jets have not yet been found near Sagittarius A*, they might exist and might be observable in the near future. 

 The researchers released the image showing the environment around Sagittarius A* in polarized light for the first time. 

 In a way, light behaves like a wave. Light waves can move in different directions. When light waves are restricted to one direction, or plane, the result is polarized light. 

 The latest image came from the Event Horizon Telescope (EHT). It is an international network of observatories working together to study radio waves connected with black holes. The EHT also provided the earlier image of the M87 black hole. 

 Sara Issaoun is with the Center for Astrophysics - Harvard & Smithsonian. Issaoun said scientists can “see” black holes: "By imaging polarized light from hot glowing gas near black holes, we are directly inferring the structure and strength of the magnetic fields…”

 She said observing polarized light made the new study different: "Compared to the previous results, polarized light teaches us a lot more about the astrophysics, the properties of the gas, and mechanisms that take place as a black hole feeds." 

 A co-leader of the research, Issaoun said: "For a while, we've believed that magnetic fields play a key role in how black holes feed and eject matter in powerful jets." 

 "This new image…shows that strong and ordered magnetic fields are critical to how black holes interact with the gas and matter around them." 

 Angelo Ricarte is another researcher from the Center for Astrophysics who was involved with the study. Ricarte said: "The magnetic field appears to be organized into a spiral, similar to M87*. This magnetic field geometry implies that the black hole can power very efficient jets that shoot off into the galaxy," 

 The M87 black hole has a mass 6 billion times that of our sun — much bigger than the one in our Milky Way. It ejects a powerful jet visible in all wavelengths of light. 

 The evidence for a jet flowing from Sagittarius A* is growing. 

 Ricarte said that researchers are hopeful about the prediction for a powerful jet in the Milky Way’s black hole. As tools get better in the coming years, he said, researchers should be able to better understand the issue from the data. 

 The researchers’ findings appeared recently in Astrophysical Journal Letters.
