Phase:
Before/Engage
Activity:
The students will be given several sealed envelopes and the Guess That Item worksheet and will be asked to identify the object inside. The students will be allowed to use any of their senses to identify the object as long as they don't damage or open the envelope. Students will work in groups and the envelopes will rotate around the classroom. Students should be given a period of time to identify the object (4 minutes) and then pass the object on to the next group. The teacher will lead a discussion at the end comparing this activity to how the structure of the atom was discovered. The teacher may choose to open the envelope, or they may allow it to remain a mystery.
Assessment Strategies:
Students will students sketch and label an atom. The teacher can check for understanding of the basic structure of the atom.
Advanced Preparation:
The teacher must find several objects (bolt, eraser, marble, etc.) to place in envelopes and seal. Eight to ten envelopes are recommended. Larger classes will require more envelopes. Print copies of the worksheet or share with students. Number the envelopes so that the students may answer the worksheet.
Variation Tips (optional):
Notes or Recommendations (optional):
The teacher may reveal what is in the envelopes or not. If the teacher chooses not to open them, explain that scientists aren't allowed to "open the package" and find out if they are "right." The scientist must use their data and findings to come up with the best possible solution. This is a good opportunity to show students how scientific ideas have changed over time with the addition of newer technologies and better data.
