Final Exam question #8
The Solar System is approximately 39 astronomical units, but if the comets are included into this is would be much larger. The theory of the captures theory the planets and other objects came within the gravitational pull of the sun. They were then unable to escape the sun's gravitational attraction. The galaxy travels around the center of it. Which is Known as the milky way. All the planets and everything in the galaxy circulates around the sun in a counter clockwise direction. 4,500,000,000 is the age of our solar system, give or take a few hundred million years.
The Big Bang Theory. About fifteen billion years ago, give or take five billion years, a huge cloud of masterpieces in all kinds of sizes was slowly rotating around itself. The Big Bang theory is a widely accepted theory about the origin of the universe. It states that between 10 to 20 billion years ago the entire universe was compressed into the confines of an atomic nucleus.
The universe initially consisted of a very hot, dense fireball of expanding, cooling gas. After about one million years the gas started to condense into different clumps called protogalaxies,which then changed into galaxies.

The updated nature trail
- We cut the prickle bushes so they wouldn't hit people when walking through the trail
- We painted the trail signs so they are more visible
- All the big logs and sticks are out of the trail and are in a pile so they are out of the way and can be took away
- There are not as many leaves all around the trail so it makes it easier to walk through
- We also took all the debris away from the bottom of the signs, and there are maps in the map box now
- Take nature walks and learn about the different plants that are around
- Teachers could also teach them about the animals within the nature trail
- When the nature trail is going to need more work on then the teachers can have students help for volunteer work
- Teachers could also just take students outside and do work out there to get fresh air and enjoy the nature
- Its a way to sow students that its good to take care of our nature so we don't lose these kinds of things
- It can be used to do test on nature and other things
- To promote a nice city and it not being trashed by it being so pretty
- To show other communities that ours is nice and we care about our environment
- They could have meetings there or any little gatherings
- Can be used to maybe expanding it or making it with more additions

Nasa 4 topics
-Dr. Arthur Holly Compton won the Nobel Prize for Physics in 1927 on his work about the scattering of high-energy photons by electrons. This is something very basic to most gamma-ray detection. Satellites provide an excellent platform from which to observe cosmic gamma-rays. When we examine our universe with gamma rays we can see things that we could never see with regular telescopes.
-On the quiz i missed one, which resulted in a 75%.
-I didnt see an activity on this one....

Nature Trail
*Dead grapevines
*many sticks and logs
*Pine trees
*deciduous trees
*Leaves of all different colors
*Chipmunk
*ladybugs
*mushrooms
*fungus
*Squirel
*moss on trees
*butterflies
*different kind of birds
*Snake holes
*Mice
The Nature trail is important to us because its good for our ecosystem, and good for our community because it provides learning for students and shows that our community cares about our world.

Climate related issues
RISING SEAS
As the earth heats up, sea levels rise because warmer water takes up more room than colder water, a process known as thermal expansion. Melting glaciers compound the problem by dumping even more fresh water into the oceans. Rising seas threaten to inundate low-lying areas and islands, threaten dense coastal populations, erode shorelines, damage property and destroy ecosystems such as mangroves and wetlands that protect coasts against storms. Sea levels have risen between four and eight inches in the past 100 years. Current projections suggest that sea levels could continue to rise between 4 inches and 36 inches over the next 100 years.
Higher Temperature
High temperatures are to blame for an increase in heat-related deaths and illness, rising seas, increased storm intensity, and many of the other dangerous consequences of climate change. Heat-trapping gases emitted by power plants, automobiles, deforestation and other sources are warming up the planet. In fact, the five hottest years on record have all occurred since 1997.Scientists project that if emissions of heat-trapping carbon emissions aren’t reduced, average surface temperatures could increase by 3 to 10 degrees Fahrenheit by the end of the century.

Myth busters
.When they guess or hypothisis what the outcome or conclusion of the experiment will be.
.They use some of the materials that we use in our labs.
.some things dont work out for them so they have to use trial and error technics.
.Writing down the results.
