Today in class we learned about Newton's 3rd law which explains that every action has an equal and opposite reaction. Students were challenged to try to protect a cheese ball from a crusher using only a 3x5 card and a toothpick.

Today we used the quizlet posted last time to review before taking a Mastery Check covering Newton's First and Second Law. If you have not yet taken this and need to review, please go through the review on Canvas and take the practice quiz. We then began learning about Newton's Third Law. This states that every action has an equal and opposite reaction. To see this, Mrs. King stood on a skateboard while students brainstormed ways to use a medicine ball to get the skateboard to move and explain how Newton's 3rd law made it possible. We also reviewed the videos that we made outside last time of students dropping two different types of sport balls to see which landed first and which came back up higher and why they were effected. We also played tug of war with a 4 way rope to see what kinds of variables will effect the equal and opposite reaction.
Today in class we will be reviewing Newton's 1st and 2nd Law by doing some fun activities. We will then go through a review online and take a practice quiz to prepare us for the Mastery Check coming up on these two laws. The review can be found in Canvas and a quizlet can be found here.
Today in class we continued to review Newton's 1st law with activities like running while dropping a ball into a cup, crashing a stuffed animal on a skateboard into a stack of books, spinning a raw egg versus a hardboiled egg, etc. These activities all show us INERTIA! Next we are learning about Newton's 2nd law which is that Force=Mass x Acceleration! Basically the more mass the object has, the more force needs to be applied in order to get it to accelerate.
Today we are learning about Newton's 1st Law. Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. We went through activity stations to understand how Newton's first law can be tested in everyday experiments.
We have already set up notebooks and gone over classroom procedures. We then did the rocket lab. In the rocket lab, we learned how to design a controlled experiment. Key concepts: how to design a controlled experiment, independent and dependent variables, how to set up data tables and graphs. Click here to review this material.
Come to this page for updates about what we did in class and how you can succeed!
Make sure your notebooks are up to date and in line with the rubric so that you can use them to the best of your ability one the final test this week. You can include anything that you were given or studied in class in the notebook. Here is a link to the final quizlet we played in class. Here is the link to the study guide and the answer key.
