Phase:
During/Explore/Explain
Activity:
1. Students will follow the procedure instructions 1-10 for the virtual lab.
2. Students will record their results in a table digitally and on their own paper.
3. The student will graph the results using the online interactive.
4. Students will answer the review questions in their journal on the online interactive.
Assessment Strategies:
The teacher will assess students' completed answers to the five journal questions at the end of the lab which will require using models from the online interactive.
Advanced Preparation:
The teacher should have previously discussed atoms and radioactive decay before beginning the lesson. Students should also know the meaning of an isotope.
This virtual lab does not give the student an option to save the activity, so the teacher should instruct the students to Print Screen to save as a PDF and send to the teacher, or print and turn in the results.
The teacher could also create a worksheet for students to record their results and turn in the work.
Variation Tips (optional):
Have students create their own models to demonstrate radioactive decay.
Notes or Recommendations (optional):
The teacher should present radioactivity and atoms before introducing the activity. This virtual simulation requires Flash and should be played using a browser that supports Flash.
