Wednesday, we had a guest speaker talk to the Fourth and Grade about electricity. We have been studying about conservation so it was interesting to hear the ways that we can conserve energy.
Then, everyone who wanted to got the chance to touch the “static ball” which was an electrifying experience!

A Shocking Speaker
Scientific Method Video
Our fifth and fourth grade classes watched a video about the scientific method. Here are all five steps. Step one: Ask a question. Step two: Form a hypothesis. Step three: Do a experiment. Step four: Write down the results of your experiment. Step five: Draw a conclusion. The last step is the Experimental stage: after you have you hypothesis and you experiment, then you do your experiment again. There was a girl on the movie and she was making a hypothesis just by feeling what is in her kitchen. She also felt wood, a pan, and styrofoam. Then she put an ice cube on all of them. Her hypothesis was that the ice cube would melt the fastest on the warmest thing. The ice cube that was on the warmest thing would melt the slowest. Her hypothesis was wrong. It is ok to reject your original hypothesis and form a new hypothesis.
Science Class- What is a Hypothesis
A Hypothesis is something that you believe will happen before you try it. We all wrote hypotheses about what we think will happen if we tie balloons to a straw that was on a string. My hypothesis was if you tape a balloon to a straw that was on a string,then depending on the amount of air in the balloon will tell you how far the balloon will go. After we tested it out I figured out that the balloon full of air went fast and twisted all the way down the rope. Then we tested it out with a balloon half full of air. It went half way down the rope. After that we tested it out with a balloon with barely any air in it and it went one fourth of the way down the rope. The last thing we tried was to tape two balloons(one on each side) and it went three fourths of the way down the rope. The reason it only went three fourths of the way down the rope is because the two balloons made it too heavy so by the time it had more power it was already slowing down.
Writing a Hypothesis in Science Class
For our experiment, we took 2 chairs,string,a straw, and a balloon. HYPOTHESIS- If Mrs. Zavon blows up a balloon and holds the air part closed and tapes the balloon to a straw then it will not fly across the whole piece of string. WHAT HAPPEND THE FIRST TIME : it was filled up and it did go all the way. THE SECOND TIME: it was filled up with half of the air and it went only half way. THE THIRD TIME: we filled it up with a inch of air and it did not go far at all. We tried to put 2 balloons and it slowed down a lot. The correct hypothesis was, if a balloon is full with air, then it will travel farther.

Fun and Yucky Science Labs
We are studying cells, tissues, and organs in Science. We did two “Instalabs” in class which were fun, yucky, and educational!
