Lesson Plan Day: 48            10/30

Teacher: P. Kirk

Subject: Science

Course: Chemistry


In fission, atoms split into nearly equal parts and energy. 

Nuclei combine in nuclear fusion. 


HS.PS1.C: Nuclear Processes
Nuclear processes, including fusion, fission, and radioactive decays of unstable nuclei, involve release or absorption of energy. The total number of neutrons plus protons does not change in any nuclear process.

Section 21.1: Nuclear reactions affect the nucleus of an atom.
Section 21.4: Nuclear Fission and Nuclear Fusion


Nuclear fission where atoms split into nearly equal parts and energy will be distinguished from the nuclei combining in nuclear fusion. 


nuclear fission, chain reaction, critical mass, nuclear reactor, nuclear power plant, shielding, control rod, fuel rod, moderator, nuclear fusion 


S will read and take notes on 21.4 from PPT, text and available printable notes.  S will work alone or in small groups to complete Study Guide 21.4.   

S groups will turn in possibly one lab graph paper and any related work requested for the Isotopic Penny Lab. 


T will go over 21.4 PPT and monitor students as they work to complete Study Guide 21.4. T will copy and distribute Study Guide 21.4. 

T has access to and can demonstrate several devices that are used to detect radiation including Geiger counter and film badges.

T will conclude and possibly collect an Isotopic Penny Lab paper from each group.

T will discuss/demonstrate the similarities and differences of Fusion and Fission.

T will ensure that EA21b has been published and that the window is open for an appropriate amount of in class and home time. 


21PPT, online printable notes, 21.4 Study Guide,  Radioisotopes resource page, periodic tables and calculators.    

Nuclear Box containing a variety of sources, detectors and other resources. Including some resources for discussing Fusion and Fission.

Isotopic Penny Lab papers, Lab graphs and the student cups containing 1oo pennies each.  

EA21b electronic assignment.


Collection and grading of group Isotopic Penny Lab papers will be a summative assessment of the teams participation and understanding of the half life concept.

Students will submit for grading the 21.4 Study Guide. Formative assessment will be done as T monitors and assists students.

Students will receive a summative grade for their performance on the electronic assignment EA21b.
