The cause of the seasons.

Most people have the wrong idea of what causes the seasons but here right now i am going to tell you what really causes the seasons. The seasons are caused by the revolving and rotating of the earth. As the earth revolves around the sun the angle of the suns rays change upon the earth. During the summer time in North America the suns rays are more direct on it thats why it is hotter in the summer than the winter. In the winter in North America the suns rays are more direct on somewhere else on the planet. How ever that is the cause of the seasons.

ZOOOOOOOOOOOOOOOOM

The book zoom was a very interesting book you would think you saw one thing then in would end up it was not what I thought it was.The book of zoom was a book with only pictures.The pictures would have a picture then the next page would be a zoomed out image of the last picture before it.When I saw the first picture i was pretty sure i knew what it was and then it would zoom out and it turned out i was completely wrong. So from there on i would look for hints to tell what it was really a picture of.This is a scientific skilled called inferring.

Every one has a different thought of what the picture is this is perspective.Each person has there own perspective it just depends on the persons mind and the way you look at it.To be a good scientist you have to have many perspectives.You also have to have a great imagination.

Scientists have to have many skills to be successful scientist.Scientists have to be very observant. they have to include sharp details and they have record the object they are observings every move.They have to especially when doing astronomy.

enigma box

Skilled scientists use certain skills to note the natural. First of all they observe by using there senses to note. Scientists also use inferring and predicting. A couple of other important skills are classifying or grouping and making models. Scientists make models to help people and them selves to understand.
The enigma box is a long black with a big whole on the top and also a tiny whole.The box has a rubber tube coming out the bottom of it.The box is a size that could fit a lot of gadgets in it.When you pour water into it the water does not come out till you pour 470ml of water into it.This box to me is very interesting to me,but i do have some ideas about it.
I have many ideas about the box but my strongest one is the one i am about to tell you.I think there is a slanted piece of plastic cutting the box in half but leaving a gap at the top.So when the water fills up on one side it will fill out the top and pour over the gap and come out the bottom tube.Then the left over pressure will push out the rest of the water.
It ends up i was wrong but i am going to tell you how it works. The water that gets poured into the big whole on the top goes into a plastic tube.This tube curves in the box.When the water is poured into the tube it does not come out until the water reaches the full height of the tube then it starts coming out.Then the rest of the water is pushed up and out of the tube by pressure.There is never enough pressure to push up all the water so you will always have left over water.As you can see this simple little enigma box is not so simple but very interesting.
