4th Grade Spotlight: Mrs. Bauknecht

Sydney, Max, and Amara describe the exciting science experiments happening in Mrs. Bauknecht's 4th grade classroom.

We have been doing some crazy science experiments in Mrs. Bauknecht's classroom. Keep reading to learn more about our most recent experiments. 

Float or Sink

Does candy float or sink? We had a Kit Kat, Butterfinger, Three Musketeer, Snickers, Peppermint Patty and Twix.  All students had to write down their hypothesis on a sheet of paper- would the candy float or sink.  We had a big bowl of water for the whole class.  The teacher placed one piece of candy into the water at a time.  It got loud in our room because we would scream if our hypothesis was right! The candy that floated was Kit Kat and Butterfinger. The candy that sank was the Peppermint Patty, Three Musketeers, Snickers and Twix. We discovered that the Kit Kat floated because it had layers with wafer that made it so light it could float.  The reason the Peppermint Patty and other candy sank was because it had a heavy cream in the inside. 

Lollipop Experiment

Have you ever wondered how many licks it takes to get to the center of a Tootsie Pop? We did too! So, we did a science experiment about it. First, we made a hypothesis.  My (Sydney) hypothesis was 128 licks.  My (Max) hypothesis was 310. My (Amara) hypothesis was that it would take 320 licks to get to the center of the Tootsie Pop. Everyone got their Tootsie Pop and a sheet that had 400 boxes. We had to tally or check the box after every lick. You could hear things in the room like, "My tongue hurts" and "I just want to bite it." There were blue tongues, red tongues, orange tongues and brown tongues! We worked for 15 minutes and ran out of time, but it looked like we were making a little progress. Students took the Tootsie Pops home to finish.  We discovered it was a different number for everyone!  Some students finished in the 500's and others were all the way up to 1000 licks.  It is safe to say that everyone enjoyed this science experiment!

Penny Experiment

How do you clean a penny? Right now we are starting an experiment about what will clean a penny better: Coke or soapy water.  So far we have made six cups filled with soapy water and six cups filled with Coke. We dropped equally dirty pennies into each cup. Then, we checked them after recess and the Coke was starting to look shiny through the water. But, the soapy water wasn't really looking like anything was happening to the pennies and the water just turned blue. We will check it again after the second recess. We plan to take the pennies out and compare how shiny the ones in the Coke are and how shiny the ones in the soapy water are. Finally, we will know which cleans pennies better:Coke or soapy water. We all predict the Coke will be the better cleaner. What do you think?

I bet you wish you were in Mrs. Bauknecht's class, too!
