Space Tech & EMS Quiz Next Week

The space technology and electromagnetic spectrum quiz will be Monday April 4th, 2016.

What to study:

Types of Telescopes

Reflecting Telescope (optical):
light from on object in space is reflected off of mirrors inside the telescope.  The Hubble Space Telescope is an example of a reflecting telescope.

Refracting Telescope(optical):
light from an object in space in bent (refracted) through an objective lens

Radio Telescope:
uses a large curved dish to collect and record radio waves traveling through space.

Spacecraft:

Artificial Satellite:
any human-made object that orbits another object in space

Space Shuttle:
reusable spacecraft that transports astronauts, satellites, and other materials to and from space

Space Probe:
an instrument that gathers information and sends the data back to Earth. Unlike satellites that orbit earth, space probes travel far into the solar system.

Space Station:
large artificial satellite that provides support systems, living quarters, and equipment so that humans can live and work in space and conduct research not possible on Earth. The International Space Station, for example, is a permanent laboratory designed for use in long-term research.

Electromagnetic Spectrum

The sequence (order) of electromagnetic radiation from longest wavelength to shortest wavelength:EMS
Radio, microwave, infrared, visible light, ultraviolet, x-ray, gamma ray. (Click here for a mnemonic device to help you remember the order.)

What is frequency:
the number of waves per time interval, such as 3 waves per second

What is wavelength:
the distance between two identical adjacent points in a wave.  For example, the distance between one peak or crest of a wave of light, heat, or other energy and the next corresponding peak or crest.

The inverse relationship of wavelength and frequency:frequency-wavelength
As wavelength decreases, the frequency of waves increases (more waves per second).
Shorter wavelength, higher frequency | Longer wavelength, lower frequency.

 

 

 

 

Tour of the International Space Station

Today we started a unit on astronomy.  Students in Science 7/8 are studying space technology and what better way to investigate than to go inside the International Space Station?

Plate Tectonics Unit Test – Friday 3/18

We will have our Plate Tectonics Unit Assessment this Friday, March 18th.

What to study:

Vocabulary

Continental Drift

  • Fossil Evidence
  • Puzzle Piece Evidence
  • Rock Evidence
  • Glacial/Climate Evidence

Seafloor Spreading

Plate Tectonics

  • Plate Boundaries
  • Geologic Features

Earth’s Interior

  • Lithosphere
  • Asthenosphere

Convection

 

 

Happy Birthday Einstein!

In honor of Albert Einsteins 137th Birthday and the fact that today is Pi Day (3/14), we celebrated by finding the circumference and diameter of circular objects around the school.  Then we recorded the class data on a chart and made a scatterplot to represent the data visually.  Do you know the relationship between a circle’s circumference and its diameter?  Oh, those brilliant Greek mathematicians…

Science 7/8 Update

This week in Science 7/8, students wrapped up learning about continental drift by finishing the Pangaea Project. During the project, student scientists were asked to explain and give examples of how physical evidence (such as fossils, rocks, and glaciers) supports the theory that the earth has evolved over time. They began, much like Alfred Wegener in the 1920s, by noticing that some of the continents seem to fit together like puzzle pieces. After trying to reconstruct Pangaea based solely on this evidence, students concluded that more and different evidence was needed. That led to a whole class discussion during which students identified fossil, rock, and glacial evidence. After analyzing the locations of the new evidence and given models of the continents, students were able to successfully reconstruct Pangaea as it may have looked 200 million years ago. Now that students have an understanding that continents are indeed drifting, it’s time to investigate why they are drifting and what mechanism causes the drift. This “mechanism” will help us understand and explore the earth changing processes of plate tectonics and the earth shaping effects of the different plate boundaries in the upcoming weeks.

Science 6 Update

This week in Science 6, students have been applying their knowledge of geologic time to create Earth History Brochures, an art project that challenges student scientists to make an informational and artistic brochure highlighting the major events, life forms, and time periods of Earth’s history. Some noteworthy discoveries include the time period when an important index fossil (trilobites) lived, when Earth’s atmosphere became filled with oxygen from stromatolite bacteria paving the way for the largest biological diversification in history (Cambrian explosion), the fact that dinosaurs were alive relatively recently (up to 65 million years ago), and when the first homo sapien ancestors evolved (about 200,000 years ago.)

Science 7/8 Update: Earthquake-resistant towers

Students in Science 7/8 are studying a comprehensive unit on plate tectonics.  They have started by learning about earthquakes, and how seismologists use earthquake waves to study the interior of the earth.  Currently, 7th & 8th graders are using real engineering techniques to build earthquake-resistant towers out of toothpicks.  The towers will be tested on an earthquake simulation table that models real earthquake waves.  Next, students will be creating an earth’s interior art project as part of our arts and science integration.  After the art project, students will be studying Pangaea and will piece together the continents as they appeared 200 million years ago using the same evidence used by real scientists.  This will immediately be followed by the processes of plate tectonics, i.e., continental drift, seafloor spreading, convection in the mantle, etc., to help explain how the continents could have moved from the Pangaea formation to their current positions.  Finally, the unit will conclude with the different types of plate boundaries and their affect on shaping the earth as we know it today.
