gizmo paragraph
Earth's rotations/revolutions have a huge effect on what season it is. For example when the northern hemisphere is getting the most sunlight, then the northern hemisphere is in summer. The southern hemisphere is getting less sunlight so they are facing winter time. When the southern hemisphere is in summer, the northern is in winter. Sometimes an equinox will occur. An equinox is when two days of the year on which neither hemisphere is tilted forward or away from the sun. In conclusion, Earth's rotations/revolutions is an important role in our life.

Zoom (Powers of 10)
Today in class we read a book called Zoom by Istvan Banyai. This book only had pictures. It would start out with an image and then it would zoom out. You would make an inference, and the next page would make you change that inference to a completely new one. This is called the power of 10. The power of 10 is when you zoom in or out to the power of 10.
Have you ever thought you were seeing something accurately but realized that, with a different perspective, you would see it differently? Yes this qestion goes through people's heads a lot. If you were looking at a self- portrait and you turned it upside down, you would see a completely different thing. If you were looking at two people having a picnic, and you keep zooming out you would eventually not be able to see the two people having a picnic.
Some scientists prefer closer looks at what their looking at. For example, a scientist that studies inside the human body is going to want a closer look. If your an astronomer you use both. You look at stars through a telescope, and you get as close as you possibly can to the stars. If you study astronomy it is important to be aware of perspective. In conclusion, perspective may help scientists study or it may make their life difficult.

The Enigma Box
Today in class we did an experiment called the Enigma Box. Enigma means "puzzle." During the experiment we were asked to make some observations. Some of my observations were that when Ms. Casey poured the water in the box, it didn't go right through the box. It took about a minute to get through the box and into the cup.I think that there is a series of tubes inside the Enigma Box.
This reminds me of my body. When you eat something it goes down your esophagus, into your stomach, through your small intestines through your large intestines, and out your rectum.(anus)
Scientists use many skills to make observations and these skills are observing, inferring, predicting, classifying, and making models. To be a successful scientists you have to be able to use these five skills. We as a class and individual had to use these skills. We had to observe how the water entered the box and how it left the box. We had to make an inference on what would happen when the water was poured into the box also.
Inside the Enigma Box wasn't really a series of tubes, but it was a tube bent into a loop.
In conclusion, the Enigma Box may seem complicated but if you use the scientific skills you can figure it out.
