ESSENTIAL QUESTION: Why and how has the atomic theory changed over time?
LEARNING TARGET: Why do theories change?
BENCHMARKS: SC.8.P.8.7
LEARNING OBJECTIVES: Students will be able to:
-Describe and illustrate the modern model of the atom and why it has changed over time.
-Explain why theories (such as atomic theory) may be modified but rarely discarded).
-Explain the atomic theory and how it has been modified over time.
-Research information for the Infograph project on Florida Everglades
-Take the topic assessment 2 exam.

Choose the sentence below that is a correct description of a scientific
theory.

connect to those that came before.
B. Theories in one scientific discipline do not affect
theories in other disciplines.
C. Scientific theories in one discipline can influence
theories in other disciplines.
D. Creativity and insight are not important parts of
developing new scientific theories.
VOCABULARY: matter, chemistry, substance, element, atom, Atomic mass, periodic table, nucleus, proton, atomic number, neutron, electron, mass number
HOME LEARNING: work on infograph
AGENDA
WHOLE GROUP
Students used the bell ringer FCAT paper to record their answer and justification, before discussing with each other.
Students were given an obsertainer and asked to determine the pattern of the container without looking. They drew and then changed containers with each other. After discussing why they thought the container was configured as they drew, they had the opportunity to change their design and redraw. Once all discussions and observations were made, students opened the containers and determined the correct configuration. This lead to the discussion that theories are often changed after other scientists have the opportunity to add input to the theory or new information comes along.
We then watched a video on the history of Atoms and the Atomic Theory. You can watch the video below.
(Right now, I am having technical difficulties uploading the video). If I can, I will try to upload at a later date. You can click the link below to access the video directly:
Students began notes on Atoms and the Atomic Theory. While we did not complete the notes, we did begin. You can find the video of the power point of the entire presentation below.
Students were then given time to work on the research for their infograph project.
