Photography; Photography is a masterpiece that captures life, on a paper. Photography back in the day used to be really expensive because they had to use huge cameras to create photos. Photos used to be created with gelatin, silver, paint, etc. Photos got cheaper because they would take a actual photo, they add warm gelatin, and a piece of paper and smash it together. This creates a duplicate of the actual photo, but its not considered a photo after its print is on the paper. The technology for photos kept getting better, until it was quite cheap to make. Today, we use digital devices to capture digital photos, that have color, before there was no color but gray and black. and the photos can be deleted forever, unlike when paper was used. Technology has improved a lot, and it makes things easier for us.

In rocket science, you can learn much about rockets. how they work, how they are built, and how they are controlled. you can also make your own rocket from home materials, to see how it works. you can make one with a balloon, a straw, tape, and string. all you have to do is tie the string to a tree branch, insert the string into a straw, tape the balloon to the straw, do not tie the balloon, and let go. it will show how a rocket can take off into space. Armstrong was the first person to be in space, with some others. a dog was once also sent into space, before humans to see how it would do. thats my assignment
