  2. Inquiry • Scientific Investigation • 1. Identify a testable question~ a testable question is one that can be answered by preforming an investigation. • 2. Research the topic~ Before an investigation can go any further, some basic research about the topic must be done. • 3. Form a hypothesis~ A hypothesis is a possible answer to a scientific question and is based on gathered info. • 4. Design an experiment~ An experiment must be designed to test the hypothesis. • 5. Collect the data~ A controlled experiment produces data. • 6. Interpret Data~ When an experiment is finished, the data should be analyzed.

  3. Inquiry Continued… • 7. Explain the results~ After gathering and interpreting data, conclusions should be made about what happened when the manipulated variable was changed. • 8. Compare results to hypothesis~ The results of the experiment should be compared to the original hypothesis. • 9. Communicate the findings~ The results, analysis, and agreement (or disagreement) of the findings with the original hypothesis should be communicated.

  4. Types of Investigations • * Making Models • * Preforming a controlled lab experiment ( with independent and dependent variables) • * Preforming a field-based investigation (natural settings) • * Observing and describing objects, organisms, or events ( collect large amounts of data to explain something)

  5. Planets • The inner planets also known as the (terrestrial planets) are very small, dense, and made of rock. Their orbits are very close to the sun. • The outer planets, (also known as the gas giants) are extremely large, cold, and made of gas (hydrogen and helium). Their orbits are farther out and spaced widely.

  6. Dwarf Planets • Pluto and Ceres are called dwarf planets. • Pluto was once considered the farthest planet. However, part of its orbit brings it closer to the Sun than Neptune, and it is about as small as the largest asteroid in the Solar System, Ceres.

  7. Dwarf Planets continued… • Ceres is another celestial body that is considered a dwarf planet. • Before the “dwarf planet” category was established, it was the largest asteroid known in the Solar System.

  8. Galaxies • A nebula is a cloud of dust and gas that exists in space, usually between stars. • It can be classified as a planetary or diffuse nebula.

  9. Planetary Nebula A planetary nebula is small. The nebula forms from material ejected from the star’s outer layers as the star begins to collapse.

  10. Diffuse Nebula • A diffuse nebula is a larger nebula with an irregular shape.

  11. Meteoroids • A meteoroid is a small, rocky body orbiting the Sun. Meteoroids are similar to asteroids but much smaller. • In fact, most meteoroids probably come from asteroids. • If one hits the ground its called a meteorite.

  12. Comets • Comets have the most elliptical orbits of all the objects in the solar system. They move into the inner solar system for only a short amount of time. Once they have passed around the Sun, they move back out into the outer reaches of the solar system again, often well past Pluto, and are not seen again for many years.

  13. Asteroids • The majority of the asteroids in our solar system can be found in the space between Mars and Jupiter. This area is called the asteroid belt. Asteroids vary greatly in size and shape and are mostly made up of stone, iron and nickel.

  14. Moon Phases • Half of the Moon is always lit by the Sun. But because the Moon is revolving around the Earth, the amount of that lit portion we can see from Earth constantly changes.The Sun shines on exactly one-half of the Moon, except during a lunar eclipse. From Earth, we can generally see only the part of the Moon that is lit by the Sun. As the Moon orbits the Earth (once about every 28 days), the amount of the lighted half of the Moon that we can see from Earth changes. These changes give us the phases of the Moon. The Moon makes one complete cycle every 29 1/2 days.

  16. The Moon Phases

  17. Solar/Lunar Eclipses • During a solar eclipse, light from the Sun is blocked out of view for a certain part of the Earth by the Moon. During a solar eclipse, the order of the Sun, Earth, and Moon looks like the following.

  18. Solar/Lunar Eclipses • During a lunar eclipse, light from the Sun is kept from reaching the Moon because it is blocked by the Earth. During a lunar eclipse, the order of the Sun, Earth, and Moon looks like the following.
