Nuclear Chemistry Lesson Plan
Half-life or a Radioactive isotope
Half-life, radioactive, nuclide, decay
Goals / Aims of The Lesson Plan
1.Determine half-life by looking at a diagram
2.Plot a graph of radioactive decay
3.Interpret graph of half-life sequences.
1. Describe the type of decay a radioisotope undergoes
2. Solve problems that involve half-life
3. Simulate the decay of a radioisotope
4. What are groups in a periodic table? How may are there?
5. What are periods in a periodic table? How many are there?
6. How many known elements are there?
Materials and Aids
graph paper, ruler, penny, textbook, drawing; computer w/interactive textbook
Read pg. 799 & look up vocabulary words radioactive, radiation & radioisotopy & infer that radio means "to send out in all directions"
1. Use Elmo to define vocabulary
2. Passout Venn and Cycle diagrams & explain how to read them
3. Students will develop a diagram based on a data chart of half life times and sequences.
1. Interpret diagram
2. Flip a penny to simulate radioactive decay
3. Plot data collected & make a labeled graph
D. Independent Practice-
1.Read pgs. 803-809
2.Do Interpreting graphs pg 805
3. We will get into chemical decomposition of nuclear reactions next class. (Reminder for me)
E. Accommodations (Differentiated Instruction)-
1. G T - Explain & use exponential ideas
2. $1000 prize poster
3. Interpret 25-3 to make inferences about half-life
F. Checking for understanding-
1.Have students hold up plotted graphs to check
2.Section assessment - Students will take a 10 question quiz the beginning of next class period.
1.Review shape of graph
2. Vocabulary review
1. Ticket or not- what is the half-life of carbon 14
2. Interactive textbook questions and refer to CFU section of this lesson for quiz information.
Every time kids hear the word "Nuclear" they are scared. Maybe rightly so, but I hope to show them the power of Nuclear chemistry. We don't have enough highly motivated futurists in Nuclear Chemistry. Maybe I can help develop one.
