Aluminum Boat Float: What Did You Learn?

Here we have three videos of students relating what they are doing/learning with a hands-on lab activity in science. The assignment was for them to design an aluminum boat that would be able to hold as many marbles as possible. You may note that one student talks about surface tension. The students had been introduced to this concept in an earlier lab. Although the application was wrong here, it is still good to see them reach back into what they have been learning.

This activity took place before we introduced the concepts of buoyant force and density. Now they have some experiences we can relate to when we do get discuss them.
