Moon Buggy

The Moon buggy is a 1 horsepower vehicle. No doors, no windows. Just some equipment and painful chairs. If anyone else made it it would probably cost 10 bucks. But it was made by Nasa, and it was for the Moon, so it cost 20 million US dollars, mind you, that was the day when an average car only cost 3000 or so. However, on the moon the moon buggy was very useful, expanding our knowledge of the moon. The only drawback was that because the moon buggy didn't have any extra supplies, the NASA team could only go to a distance where they could walk back from.

However, the new moon buggy has solved the problem. The new moon buggy costs 4.5 million dollars, looks like a truck with a round cabin, however it is a very high tech piece of equipment. On earth it weighs 4 tons but on the moon it weighs 760 kilos. Its top speed is about 16 kph. The moon has 12 wheels, and a motor for every other wheel. It has powerful computers that can make it navigate ditched and rocks. Mos importantly, it is sealed and has its own air and food supply, making it be able to travel much further much faster ans much safer. However, if you do get bogged down you can exit the buggy through a door that leads right into your space suit. No more hopping around trying to get it on. All you have to do is stretch you legs our in to the suit, put your arm through the top part and start walking. The space suit would be full of supplies that hopefully is enough to get you back. However breaking down is very unlikely.

Its tires are from a tractor, chosen for their toughness.. It can change its height off the ground for bumpy terrain. Its so good on hard terrain, that even on earth weighing 4 tons it can climb over 30 degree slopes. However, all this is useless since the moon missions have all been canceled. The 4.5 million dollar piece of modern machinery will just go to a warehouse for the rest of its life.

Moon Phases

I noticed that the parts of the moon change when the position it is to the sun changes, because before I always thought that part of the moon is blocked because there was a meteorite blocking it.

We see different parts of the moon each nght because we can only see the moon when the sunlight is reflecting off it. So as the moon orbits the earth, the sunlight hits less or more of the moon, so we sometimes see a lot of the moon and sometimes we don't.

A lunar month is the amount of time from 1 full moon to the next.

Sun

1. The Southern Hemisphere gets the most concentrated light, and when its summer in the Northern hemisphere, the Northern hemisphere gets the most concentrated light.

2. Then the Southern hemisphere gets little or no light, so it winter there, while it is summer in the North.

3. There would be less heat because it would be more spread out and less concentrated since it shines over a bigger area.

4. The very middle of the North and South poles are the coldest because the sun almost never shines there, and if it does, only the very edge. While the equator is the hottest because it gets the full blast of the sun all year round.

5. When it is winter in the Northern hemisphere the toothpick shadow would be longest, while when it was summer in the Northern hemisphere the shadow would be shortest.

6. If the sun is directly above a square, it gets the most heat and light, while when its toward the south or north of the square, the heat and light received is less.

7. Seasons are cause when the sun is shining at different parts of the world far and close to a certain place. When the sun rays are shining closer to a certain place its spring then summer, but as it goes farther away is fall and winter.
Use your observations of an Earth-sun model to write an explanation of what causes the seasons.

The study of waves effect everyone. If no one studied waves there would be no internet, phones, RC toys. Planes wouldn't exist because they would have to fly close to the ground in order to navigate. Human kind would have never broken the sound barrier in flight, nobody would be sent to space. Without the study of waves humans kind would be reduced to living in small towns. Learning only what that small town knew and never going anywhere. Living on meat cooked on fire and surviving on the heat of fire in the winter. Making your own clothes. Everyone would be farmers of hunters.
