ESSENTIAL QUESTION: Why and how has the atomic theory changed over time?
LEARNING TARGET: Why do theories change?
NGSSS: SC.8.P.8.7
BENCHMARKS:
-Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are the smallest unit of an element and are composed of sub-atomic particles (electrons surrounding a nucleus containing protons and neutrons).
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
BELL RINGER: Answer and justify. SC.8.N.3.2 The Role of Theories, Laws, Hypotheses, and Models
Scientists create
both scientific theories and scientific laws as they make observations and
conduct experiments about the natural world. Which of the following statements most
accurately compares the difference between scientific theories and
scientific laws?
A.
Scientific laws are based on
evidence, while scientific theories are not.
B.
Scientific theories involve only
biology, while laws involve all types of science.
C.
Scientific theories involve
mathematical equations, while scientific laws are based on observations.
D.
Scientific theories are ideas
that explain natural events, while scientific laws more reliably predict
natural events.
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 completed and shared their answers to the bell ringer.
Students then did independent work. Those that had to complete the topic 2 assessment did so and those who needed to work on their infograph did so. All infographs are due in class on Monday.
