First the students were shown a series of everyday objects -- paper clips, pencils, pennies, etc. We filled out scientific "logs" showing whether we thought the object would sink or float, and we discussed one of the most important aspects of making a prediction: Our prediction may be different from our friend's ... and that's OK!
Raise your hand if you think the eraser will float.
Next came the fun part. We headed outside to test each object and record the results, noting that in this case our results would all be the same since we were watching the same experiment. Each student got a turn dropping one item into the water.
The results ...
Finally, I gave the students three minutes to run around the playground and find one object from nature. We conducted a final experiment to see if our rocks, branches, pinecones, and leaves would sink or float.
Some of us just couldn't contain our excitement (or our disappointment) when our predictions were right or wrong.
A correct prediction ...
... and an incorrect one!
Science -- and kindergarten -- is SO MUCH FUN!
