Teaching strategies If a student doesn’t participate in an inquiry activity, how do you cope? Inquiry has challenges to keep all students on track.
Inquiry is cool but if the student is not motivated with the activity—make it meaningful
Some students don’t know how to start—help
Processes needed that model scientific method so they see what is needed
Sometimes it’s the A student who feels uncomfortable not being given the exact instructions. The distracted student often manages well . . .
Define roles specifically Have small groups so each are needed to participate
Remove from activity so they are not disrupting the group
Some take over the activity—
Bring in speakers—personal trainer . . . etc.
Reality
40, 40, 40 40 days for test 40 months for college 40 for life . . .
Brian Kate Kinsella Note-taking scaffold Vocab strategies
Term: Definition students give example and/or image http://www.montgomerycollege.edu/Departments/mcmcpspd/kinsella.htm http://www.sccoe.k12.ca.us/depts/ell/kinsella.asp http://www.scoeorg/docs/as/AH_kinsella2.pdf
Example for ell
ACTIVITY (from tab 4) How can radar “see”? Polarized glasses OR 3-D glasses (from Rainbow Symphony) Any vehicle windshield or window
Discover polarization
Mini RF uses circular polarization
Introduce students to properties of light waves and understand radar Review ems (electromagnetic spectrum)and relate to mini RF
Recall MEMORY curve http://www.wired.com/medtech/health/magazine/16-05/ff_wozniak? currentPage=all
*****google memory curve or memory retention repeat reminder reinforces memory 1 : 10 : 30 : 60 day reminders
What instruments use different frequency waves from the regions in the electromagnetic spectrum?
Science Hack solid YouTube YouTube TeacherTube
Webelements
Song about ems on YouTube Use of the regions
****Radio – Naiontal weather service broadcasting activity am in the pm AM, FM/ shortwave, etc (sun is radio source but at night you can pick up longer/distant sources bounce off atmosphere—more reception over night)
Microwave - - microwave ovens, Radar
IR heaters, remote control, heat sensor , Super8 night vision, night-vision goggles (some are light boosted) some apps for phone are just colored filters
Visible eye, camera, telescope
UV produced by the Sun, goggle sanitizer, bug lights, UV beads, nail polish dryer
X-rays custom
Gamma Incredible hulk!, black hole as transmitter, cancer treatment
Radio waves difference from light
Longer wavelengths—longer distance between the crest of the waves (light waves can be seen by the human eye)
Lower E Pass through clouds Pass through objects (walls)
Nylon rope to demonstrate waves Energy of wave = energy to displace the rope
Frequency = time to travel a distance Energy travels faster Vibrates quicker
Light DOES NOT WIGGLE! (alternating fields in electricity and magnetism not met till college
= electric and magnetic wave BOTH oscillating at the same time Dominoes—spaced too far apart to knock each other apart Then alternate (combining the 2 sets of dominoes) they will knock each other over – simulates waves ==electro magnetic spectrum how many waves pass a given point in an interval—wave has more energy and can be dangerous X and gamma rays affect cells and are dangerous
What I know—add to the W section of KWL
RADAR Radio Detecting and Ranging Used for remote sensing Weather detection, passes through clouds View earth from Space Mount Pinatubo pics in radar in FALSE COLOR
Sees vegetation, lava flows and mud flows
False color: can’t see radar with eyes. We tell the computer to assign colors at particular frequencies and how much is returned.
Hubble Space Telescope—Orion Nebula Students expect to see the color in the same way HST does—but see fuzzy white patch. Allows us to see features that our eyes cannot pick out. Allows us to make sense of what we see.
Vertically and horizontally polarized.
What do you know ? Polaroid camera . . . polarizing sunglasses
Light source in multiple directions Polarization filters it in one direction. WRONG: filtering makes sense at a certain level 2 filters block BUT a third between allows light to pass—so not filtering Vibrations in one direction
{polarization is about directionality/orientation} way in which the e/m wave oscillates a it travels along—horizontally OR vertically can filter out waves in a particular direction Benefits are: removes glare on objects (fishermen looking into water, 3-D movies, photography) Ansell Adams used polarizing filter to darken the sky b/w and brighter blue in color
Wave oscillates in a circle (corkscrew)
Mini RF sends light down and receives return
ACTIVITY using polarizing filters http://www.rainbowsymphony.com/3d-polarized-glasses.html
Procedure Work with partner How do they reduce the amount of light passing through them
Look at different features, reflections. May notice subtle differences With 2nd set Put on top of each other (and reverse)
Rotate one by 90o Light between 2 = zero
Why?
(Filtering both horizontal and vertical)
Light reflected by shiny, transparent material is partly or fully polarized
Sun through picket fence, some light blocked
OUTSIDE Look at reflected light off parked car—window—tinted windows of building Compare how things differ, how you see differently Stress or strain on windows NOTE orientation to the Sun . . .
Car window checker-board pattern Stressing tempered glass allows it to behave as a grating changes horizontal to vertical Rotating made it lighter or darker Filter through clouds
Wikipedia polarization and polarizing filters
Light travels out in all directions in all polarizations
Photon travels in wave The energy is traveling in wave Filter absorb some wavelengths Energy absorbed and should become warmer but convection loss More absorbed by glass and radiated out
Triple pane in glass in house reflects light (heat energy)
Windows stop IR being radiated out of car, so car heats up Glass opaque (relatively) to IR
Light reflects off water Clear light bulb and CD case as light reflected off at angle will get effects
Reflection of sunlight from cell phone
Mini RF connection Transmits a microwave pulse to the Moon and measures the reflected energy Transmits circular polarized radar—receives horizontally and vertically polarized light Circular pattern in one direction Mini RF notes if there is a change in the reflected amounts—is the surface rough or smooth
Image shows mini RF over visible image—lighter mini RF strip shows lots of reflection

TOPOGRAPHIC map Elevation, relief
Far side higher except for basin Blue NOT water/oceans
Back too GIS, map has been made rectangular rather than circular—shows landing sites
Tool bar has different maps Move with Zoom with + Zoom out with - or use the magnifying glasses o the top menu bar
Gradicule map: gives GRID LINES 30o apart starts at Equator in middle and 0 (prime meridian is the middle of the near side) Bottom latitude = -90 Top goes to +30
Where did astronauts land?, close to 0, 0
Search attributes function Name a feature
+ how many craters on the near side compared to far side assign grid #s and let pairs check # craters craters you can see when you zoom in TWICE 1: 54 mill . . . How do you count the partially covered craters?
App Microsoft photosym Look 360o sphere as a flat image and you can see the distortion—
Do you exclude the poles, which are distorted (mercatorial distortion)?
Sources of error What were you counting as craters? Dots, large feint, etc? Move on to another research question Which side of the moon has more iron in its crust? GO TO iage bases
GO TO Clementine derived
GO TO FeO
Research Q 3 How is amount of iron related to height?
Show site (you are already familiar with the moon), asked questions, brainstormed ideas and then looked at the answers
2nd research Q let us work out how to investigate FeO
Now have t derive our own question—NOT a WHY question because hard to derive answer.
COMPARE How many in this region? Etc.
Brainstorm q and then seek answers . . .
Iron oxide vs titanium oxide on the Moon. Which covers the larger surface area? Hypothesize why.
