In the end, the amount of work you do is exactly the same. Students conduct a simple investigation. Students employ simple equipment and tools to gather data and extend the senses. Students use data to construct a reasonable explanation of how levers work. Students communicate investigations and explanations.
Students discover that the position and motion of objects can be changed by pushing or pulling.
The size of the change is related to the strength of the push or pull. Technological solutions have intended benefits and unintended consequences. Some consequences can be predicted, others cannot. In this case, all students can make predictions while one or two volunteers can carry out the activity in front of the room. With the entire class working in teams, the hands-on portion of the challenge will take approximately 30 minutes to complete.
