For each show the script (generally) and order of segments will remain static.

Once the MSR is full Craig H. welcomes everyone and introduces the video sequence. [understudy: Tim]

PART 1 “Plant Earth”[3 mins] (Peter may have a DVD of this we could use)

“My name is Craig Hartsough and I would like to welcome you to the 2011 NCAR Super Science Saturday Showcase! Our showcase is about the science of Earth…Planet Earth” [cues the start of the video]

Craig H. continues…

PART 2 Definition of the Nature of Science [2 mins]

[From the National Science Teacher’s Association Preamble to The Nature of Science] “Science is characterized by the systematic gathering of information through various forms of direct and indirect observations and the testing of this information by methods including, but not limited to, experimentation. The principal product of science is knowledge in the form of naturalistic concepts and the laws and theories related to those concepts.”…

Alternate Def. for Nature of Science

From the Understanding Evolution for teachers website at UC Berkeley (http://evolution.berkeley.edu/evosite/nature/index.shtml) “Science is based on the premise that our senses, and extensions of those senses through the use of instruments, can give us accurate information about the Universe. Science follows very specific ‘rules’ and its results are always subject to testing and, if necessary, revision. Even with such constraints science does not exclude, and often benefits from, creativity and imagination (with a good bit of logic thrown in)” …

Craig Transitions…

PART 3 Science Measures

“…a very important part of science is measuring things you are studying. One of the things we do is observe the things we want to understand and then figure out how to measure them, just like you are observing right now! We use satellites, radar, etc. to observe planet Earth…and THIS is what we’ve discovered!”

Peter (1) The Earth/Sun Size and Distance Relationship

PART 4 The Earth is affected by the Sun Notes: set up a scale model of the distance and size difference of the sun to the Earth, in the MSR. I found this site to assist our setting up the model.
From NASA: http://sdo.gsfc.nasa.gov/epo/educators/activities/sunearthsize.php
We have created a *model* of the solar system.

“ Our Earth is has weather, and many scientists at NCAR study weather! A really important thing to know about weather is what drives the weather. Who knows what makes weather happen? [wait for answers] Yes, it is the Sun! How far away is our Sun?! [wait for answers] Right! 93 M miles (or 150 M km)! We have set up a scale model of the Sun and Earth to show just how far part they would be if we could fit them in this room. Who can see the picture of our Sun in this room? [wait for some little one to answer] Right! Well, where is the Earth [let some of the smaller children move about the room looking for it] It’s right over here…and VERY tiny compared to the sun. If our Sun is that small compared to the Sun, do we on Earth receive much of it’s energy?! No! We receive x% of what the Sun sending out into space all the time. Lucky for us our Earth traps the Sun’s energy and makes our planet warm. Geoff, how does the Earth trap the Sun’s energy?!

PART 5

“Well, it’s call the Green House Gas Effect! Some of the gases on Earth are sensitive to the energy from the Sun and ring like a bell when the energy hits them. In this container I’m going to show…………………………………………………………….and that is how the energy is saved in our atmosphere, but some of that energy ESCAPES!”

Jen Kay

“That’s right Geoff, some of the energy bounces off planet earth because parts of Earth are reflective like a mirror! [ Demos of: · Albedo using heat lamps – maybe using different surfaces · Radiation “from the sun” detected with IR sensons (thermometers – Tim has these) · Clouds reflect (if it is cloudy during the day its colder at night (corollary); and if it’s cloudy only at night vs. the day (it’s a warmer night) · evaporative cooling: show how wet things …Peter what else can affect the weather on Earth?!”

ClimateConsiderations

The CLIMATE can affect the weather….What? What is climate do you ask?! Well, there are lots of things that affect the weather and those different things make the Earth’s typically weather patterns. Under you seat is a piece of paper with a description on one of those things that affect the weather on Earth. Find a piece of paper and I’ll call on you to read your climate clue”
