Name _________________________________________________ Date _____________ Period ___ Atoms Activity 1 What is an atom? ____________________________________________________________________________________ Atoms make up matter. Anything that is matter has ____________ and __________________ Because of these two statements, atoms must have ______________ and _________________ Name the scientist that matches the description from below Contributor Description a. Greek philosopher who said that atoms could not be divided, created, or destroyed. b. Greek philosopher who thought that matter is made up of fire, water, air, and earth. c. English teacher of the 1700s who stated that matter is made of atoms that cannot be divided. Why did more people believe Aristotle over Democritus? ____________________________________________________________________________________ Why couldn’t Democritus prove that atoms existed? ____________________________________________________________________________________ Describe the speed atoms move in a solid, liquid and gas each. Recall our information from last week for the “particles” that make up each state of matter. ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ Name _________________________________________________ Date _____________ Period ___ Atoms Activity 2 What is an atom? ____________________________________________________________________________________ Atoms make up matter. Anything that is matter has ____________ and __________________ Because of these two statements, atoms must have ______________ and _________________ Contributor Description a. Greek philosopher who said that atoms could not be divided, created, or destroyed. b. Greek philosopher who thought that matter is made up of fire, water, air, and earth. c. English teacher of the 1700s who stated that matter is made of atoms that cannot be divided. d. English scientist who discovered electrons. e. Student of Thomson who discovered the nucleus and protons. The modern atomic theory states atoms are made up of two areas. Label those areas correctly below. 1. 2.

Recall our information from last week for the “particles” that make up each state of matter. ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ What is the nucleus? ____________________________________________________________________________________ What is the electron cloud? ____________________________________________________________________________________ Think about the history of the atomic theory. Do you think our idea of what the atom looks like or what it is made up of will change at some point?

English teacher of the 1700s who stated that matter is made of atoms that cannot be divided. d. English scientist who discovered electrons. e. Student of Thomson who discovered the nucleus and protons. f. Scientist who discovered that the nucleus contains neutrons in addition to protons. The modern atomic theory states that atoms are made up of 2 areas of the atom and 3 particles. Label all of the areas and particles in the diagram. 3. 1. 4. 2.
