Getting into the fossil record.
http://www.ucmp.berkeley.edu/education/explorations/tours/fossil/index.html
Focus Questions
Directions: Answer the following questions as you navigate through Getting Into the Fossil Record.
BONUS: You have been hired by National Geographic Magazine to journey to Inner Mongolia in search of fossils. You have the good fortune to find a site filled with many fossilized leaves, teeth, bones, eggs and even footprints from a variety of creatures. Amidst this treasure trove of ancient life you find no trace of insects. Your research partner concludes that no insects lived here at that time. What other hypothesis might you suggest to your partner?
Focus Questions
Directions: Answer the following questions as you navigate through Getting Into the Fossil Record.
1. What kinds of questions can the fossil record help us to
answer?
2. Describe the difference between a body fossil and a trace
fossil.
3. Why are organisms that are buried rapidly more likely to
fossilize than those that are buried slowly or not at all?
4. Describe two ways an organism can become a fossil without
being buried in sediment.
5. How does the environment affect the formation of fossils?
6. Describe three factors that could prevent an organism from
long ago from ever turning up in a fossil collection today.
7. How are geologic maps useful to paleontologists?
8. In your own words, explain why the fossil record is not
complete.

INTERACTION IN ANIMALS-2 ESO
http://science.howstuffworks.com/zoology/all-about-animals/animal-migration1.htm
What happens to your body if you drink a coke right now?
Have you ever wondered why Coke comes with a smile? Because it gets you high. They removed the cocaine almost 100 years ago. Why? It was redundant.
• In the first 10 minutes: 10 teaspoons of sugar hit your system. (100% of your recommended daily intake.) You don’t immediately vomit from the overwhelming sweetness because phosphoric acid cuts the flavor, allowing you to keep it down.
• 20 minutes: Your blood sugar spikes, causing an insulin burst. Your liver responds to this by turning any sugar it can get its hands on into fat. (And there’s plenty of that at this particular moment.)
• 40 minutes: Caffeine absorption is complete. Your pupils dilate; your blood pressure rises; as a response, your liver dumps more sugar into your bloodstream. The adenosine receptors in your brain are now blocked, preventing drowsiness.
• 45 minutes: Your body ups your dopamine production, stimulating the pleasure centers of your brain. This is physically the same way heroin works, by the way.
• > 60 minutes: The phosphoric acid binds calcium, magnesium, and zinc in your lower intestine, providing a further boost in metabolism. This is compounded by high doses of sugar and artificial sweeteners also increasing the urinary excretion of calcium.
• > 60 minutes: The caffeine’s diuretic properties come into play. (It makes you have to pee.) It is now assured that you’ll evacuate the bonded calcium, magnesium, and zinc that was headed to your bones as well as sodium, electrolytes, and water.
• > 60 minutes: As the rave inside you dies down, you’ll start to have a sugar crash. You may become irritable and/or sluggish. You’ve also now, literally, pissed away all the water that was in the Coke. But not before infusing it with valuable nutrients your body could have used for things like hydrating your system, or building strong bones and teeth.
This will all be followed by a caffeine crash in the next few hours. (As little as two if you’re a smoker.) Want to know what happens after that? Check out what happens to your body after you drink a coke, every day for a long time.
Coke itself isn’t the enemy here. It’s the dynamic combo of massive sugar doses combined with caffeine and phosphoric acid, which are found in almost all sodas. Moderation, people!

ACTIVITIES EARTH'S ATMOSPHERE
Earth´s Atmosphere
The
Earth´s Atmosphere is made up of a
mixture of gases, mostly …………………………..
and ……………………, that wrap around the earth like a blanket. The
air of our planet is ……………….%
Nitrogen and just under ………….%
Oxygen.
Without
the atmosphere we would not be able to ………………………….here.
Those gases protect us by blocking out dangerous rays from the ………………………. And making Earth a perfect
habitat for ………………………….. and ……………………………….
The
Earth´s atmosphere has ………………………….layers,
Troposphere, Stratosphere, Mesosphere, ……………………………..
and Exosphere. Atmospheric gases
become ……………………… as you go higher.
The
Troposphere is the ………………………..layer of the atmosphere. It
begins at the surface and extends to between ……………… km, (23 000 feet) at the Poles and …………………… km, (60 000 feet) at the equator. This part of the
atmosphere is the most …………………… As
you climb higher in this layer the temperature drops from 17 degrees Celsius
(DC) to ……………………… DC. The
Troposphere is known as the ……………………….
Layer since snow, wind and ………………..
Stick to this layer.
The
stratosphere starts just above the ………………………… and extends 50 km (31 miles)
high. This part of the atmosphere is ………………………
and less dense. The temperature here increases up to -3 DC, due to the ……………………………. of ultraviolet radiation.
The O zone layer is in this layer. 99% of ……………..
is located in the Troposphere and Stratosphere.
In
the Mesosphere the temperature falls
to as low as ………………………. DC. This is
also where most ………………………… burn up
when they enter the atmosphere.
Thermosphere is know as the ……………………… atmosphere. The Thermosphere also includes the………………………., a region which is filled
with many charged particles.
The
Exosphere starts 500 km above the ………………………… and is the highest layer. It
reaches until it merges with ………………
