Chemistry is a branch of science that has been around for a long time. Chemistry is dated back as far as prehistoric times. Chemistry has been around for so long that scientist have put it in 4 general chronological categories. These four categories are prehistoric, beginning of the christian era, end of 17th century(alchemy) traditional chemistry and modern chemistry. Some of the very first recorded chemist where men like democritus and aristole. These men where alive in the B.C era and have a lot of influence on how we do modern chemistry today. Starting with Democritus the man who claimed that the atom is the simplest unit of matter. Democritus of ancient greece asked the question could matter be divided into smaller and smaller pieces forever or was there a limit to the number of times a piece of matter could be divided?

Democritus had a theory that it would eventually get to small to cut anymore. This piece would be unable to split anymore. He named this indivivsible matter atomos. To Democritus of Greece, atoms were small, hard particles that were all made of the same material but were different shapes and sizes. He said that they were always moving and capable of being joined together. Aristole of ancient greece added to the theory by declaring the existence of our only four elements: Fire, air, water and earth. All matter is made up of one of these four elements and matter is made up of these four elements and matter had four properties: hot, cold, dry, and wet.

Lesson 3: Literature, The Gadget War

Objective:
1. Students will read, discuss and write about the book, The Gadget War.
2. Students will discuss the positive and negative aspects of inventions.
Time Frame:

This lesson will take 3 to 4 weeks. This lesson can be overlapped with lesson 1. This lesson is an integrated lesson that can take place during traditional reading instruction time. This lesson is primarily whole class or small group activities.

Materials:

The Gadget War, Betsy Duffey (74 pages)
Questions for reading comprehension and class discussions.
Procedure:
1. Students will read The Gadget War. The class will read the first chapter together. The class will discuss the characteristics of the main character, as well as the real inventors mentioned in the story.
2. The class will continue to read in small groups (three to four students) taking turns with the reading. Students will discuss questions together in their groups with the teacher rotating through the room. They will write their answers to questions independently.
3. The class will continue to read in groups, as a whole group. It is also important to discuss the real inventors in the story.
4. Students will brainstorm inventions they feel are helpful to people and those inventions they feel are harmful.
5. Students will write about how inventions can be helpful and harmful.
Closure:

Children will share their ideas, thoughts about harmful vs. helpful inventions.

Culminating Activity:

Children will draw their own gadget on large construction paper. They need to label the gadget�s parts. (if materials are available, they can build their gadget). Children will share their gadget and how it is helpful to people.

In order to build their own innovations, students need background information on what they are interested in learning about. This information can be integrated into the school day as the science curriculum. There are different kits created to teach students how to build their own machines, such as Electric Circuits (put out by STC- Science and Technology for Children), Motion and Design (STC) and Magnetism and Electricity and Magnetism (put out by FOSS- Full Option Science System). Having this hands-on experience will provide students with the motivation and experience to create their own inventions.

In order for students to create their inventions, the time must be built into the day. Children should be encouraged to collaborate on their work either in small groups or with a partner. Children need to go through steps to prepare themselves to make their creation. There are some suggested guidelines attached to this lesson. Students should share their plans with each other and gather suggestions from each other before they begin. As they are building and creating, students should keep a science journal about the process of making their own invention. When their inventions are complete, the students should have a way to display their projects. This inventions can be displayed in the classroom, entered into science fairs or even entered into invention contests for young people.

Suggestions:

The Gadget War is appropriate for children in second through fourth grade. For older children, using the fiction book The Bomb by Theodore Taylor is recommended. This book will allow for the same discussions about the negative and positive aspects of inventions, but within a real historical situation. The same procedure can be followed for this lesson with The Bomb, using teacher-made questions for reading comprehension and class discussion for the story.
