Use the materials on your table to create what you think a black hole would look like Use the materials on your table to create what you think a black hole would look like Make sure you have a reason for every piece you use Make sure you have a reason for every piece you use

307/12/06 What’s the plan Stan…. Explore and common misconceptions about black holes through construction of a model of the black hole Explore and common misconceptions about black holes through construction of a model of the black hole

407/12/06 Active Galaxies Educator Unit Essential question: Essential question: –What do active galaxies look like when viewed from different distances? Science concepts: Science concepts: –The small angle approximation has limits. –The angular size of an object depends on its distance and its physical diameter.

1107/12/06 Masses of Black Holes Primordial – can be any size, including very small (If <10 14 g, they would still exist) Primordial – can be any size, including very small (If <10 14 g, they would still exist) “Stellar mass” black holes – must be at least 3 M o (~10 34 g) – many examples are known “Stellar mass” black holes – must be at least 3 M o (~10 34 g) – many examples are known Intermediate black holes – range from 100 to 1000 M o - located in normal galaxies – many seen Intermediate black holes – range from 100 to 1000 M o - located in normal galaxies – many seen Massive black holes – about 10 6 M o – such as in the center of the Milky Way – many seen Massive black holes – about 10 6 M o – such as in the center of the Milky Way – many seen Supermassive black holes – about M o - located in Active Galactic Nuclei, often accompanied by jets – many seen Supermassive black holes – about M o - located in Active Galactic Nuclei, often accompanied by jets – many seen

1207/12/06 How does this apply? NSES Content Standard A: Science as Inquiry Content Standard A: Science as Inquiry –Abilities necessary to do scientific inquiry –Students make calculations to test the small angle formula (hypothesis and observation). –Using their own calculations, the students formulate and revise the theory about an object’s size. –After having analyzed measurements of nearby objects, students answer questions that engage thought and analysis about real objects in space. –Understanding about scientific inquiry –Students learn how scientists determine the distance and/or size of an object in space. Content Standard B: Physical Science Content Standard B: Physical Science –Motion and Forces –Jets of materials are ejected at velocities light speed from the black hole in an Students answer questions to help them how big the jets from AGs are, and how can see them at vast distances. Content Standard D: Earth and Space Science Content Standard D: Earth and Space Science –Origin and Evolution of the Universe –Active galaxies are a fundamental part of the evolutionary process of the universe. Content Standard E: Science and Technology Content Standard E: Science and Technology –Understanding about science and technology –The small angle formula is an essential tool used by astronomers to get physical dimensions of astronomical objects. Content Standard G: History and Nature of Science Content Standard G: History and Nature of Science –Science as a human endeavor –Students answer questions about the ability of the human eye to distinguish objects, showing how this activity affects them in daily life. –Students see that by working in groups they can formulate better hypotheses about scientific inquiries due to the extra input from others.
