This WebQuest was designed for third grade students learning about The Solar System. I would suggest using this WebQuest as a project while studying the planets.
In my third grade class, I have 21 students during social sciences. I would split my students into groups or 2-3. I have 3 students who receive special education services, and I would make sure that they are with students who can help them with this assignment. I do not have computers in my classroom, so this assignment would be done during the class's "special time" when they are in the computer lab. They only have computers every 5 days, so this assignment would need a few classes to complete. The groups of students would probably need at least 2 classes to find their information and 2 classes or more to complete their PowerPoints.
I would have my students present their PowerPoints during social science time at the end of the day. Hopefully, I would be able to get my hands on a SmartBoard for the afternoon. Only about 2 or 3 groups would be able to present each class. Again, I would need a few days to complete the presentations.
Don't forget to check out the links in the resource section on this page, as well as throughout the WebQuest, for some other great websites that go along with this WebQuest.
