Draw a sample web on the overhead and have each group “web” things they know about eyes.
Ask students prompting questions to help them develop a web “How do our eyes work?, What do our eyes do for us?”
Allow each group to present their web to the class. Post each web on the bulletin board. As each group presents, add ideas to the class web on the overhead using correct and appropriate terminology.
Evaluate class knowledge by looking at the group webs. Assess participation in the group activity by moving around the room and listening to the students during the webbing activity.
Explanation (3 class periods – 45 min each)
Procedure:
Pass out the “Eye” DVD worksheet.
Tell students to complete the worksheet while watching the video on eyes (10 min). After the video, collect the worksheet and assess for completion.
Assign students a partner to work with for the WebQuest.
Tell students we will now begin an “Eyes” WebQuest and sign out one laptop computer and two sets of headphones to each pair of students.
Write the URL of the WebQuest on the board (http://homepages.stmartin.edu/students/jennifer.bustos/webquest.htm)
After the web quest is complete, have students clear their desks except for the notes they took from the WebQuest. Pass out the WebQuest evaluation worksheet and ask students to answer the questions using only their WebQuest notes. (students may not work with partners for this activity)
Closure and Evaluation: (1 class period - 45 min)
Assess students by moving around the room and listening to the groups discuss and answer the WebQuest.
Collect the WebQuest notes and WebQuest evaluation and grade according to specified rubrics.
Also grade for accuracy in spelling and grammar. Put the class web back on the overhead. Ask the class to discuss which areas and questions from the webbing were covered in class “What did we learn?”. Add any new topics learned to the web. Ask the students what topics we did not cover that they would like to know more about and make a list. If there is time, discuss some of the topics students would like to know more about. Use prompting questions to allow students to figure out answers for themselves.
