[|Solar System Model in 3D]-This might be the coolest site on the web! Why use models? (This requires the new flash player) This above link is a good one for the first lab. Discovery streaming has a cool video called the reason for the seasons which would go well with lab 1. I might try to set up the globe/heat lamp experiment during the morning, then view the video which discusses axis, tilt, revolve, rotate. Afterwards, the students can perform the flashlight experiement. media type="youtube" key="wAjQ_FvHcTY?rel=0" height="360" width="480" The above video is a kindergarten presentation of seasons on earth. Note how "Bob" is just about where Fairbanks Alaska is, a very important part of our science lessons. The tilt of the earth part starts at about 40 seconds in media type="youtube" key="yQ34-2cuzfY?rel=0" height="360" width="480" Bill Nye-Seasons Clip. Really drives home the point that the tilt of the earth is what causes the seasons, along with the rotation of the earth. Reason for the Seasons [|Website]-From the website... Good EARTH/SUN/SEASONS diagrams and angle of the sun stuff. From the website... //Some people have the misconception that different seasons happen because sometimes the Earth is farther from the Sun and sometimes it is closer. It makes sense -- when you are close to the Sun, it should be warm and summery, and when you are far away, it should be icy winter -- but this is not true. The Earth travels around the Sun in an almost perfect circle (it is only slightly eliptical -- the most accurate way to draw the earth's path around the Sun is as a circle). So it really doesn't change by much how far away we are from the Sun. Besides, we have summer in North America when it is winter in South America, so something else must cause the seasons.//

//MOON PHASES! See the video in my content of discovery streaming called...// Space Exploration: Phases of the Moon This video would be great to preview the lesson. The speaker previews and defines moon phases, but does not go into what they are in detail until 20 seconds in, so this might provide a good preview to the card sort of moon phase pictures, then get into if they are correct by watching the rest of the video. Also, we could do a talk to the text while watching.

Lab 7-Tides-See the video clip of Tides: A Closer Look At Space-from discovery streaming. This is bookmarked in my content. Here is a cool and simple picture of tides, with a simple explanation. It is at [|Ocean Tides-Geography for Kids] media type="youtube" key="CTQ6ciHENgI?rel=0" height="315" width="560" In the lab, we make models of the sun, earth, and moon. This video does a similar demo of this. media type="youtube" key="-mBvBdGTkR8?rel=0" height="315" width="420" This shows spring and neap tides, with some cool instrumentation along with the moon phases. It may be helpful for students to view this video before answering question 3 on journal page 20. This is [|whytides.gif] from [] It should be helpful for journal page 21.
