8.1 Contact Forces Why do things sometimes get damaged when they hit each other?

Students investigate causes of motion, and develop the idea that objects that collide can push on one another while they are in contact. Students connect the changes in the kinetic energy of an object to the energy being transferred to and from the object due to forces, and determine that the kinetic energy of an object is based on the two factors of mass and speed. Last week we conducted both Horizontal and Vertical impacts in the lab. Students have come to a conclusion that when two objects collide its more than just a crash!

WE are Respectful: Our classroom is a safe space to share.

We provide each other with support and encouragement. We share our time to talk. We do this by giving others time to think and share. We critique the ideas we are working with but not the people we are working with.

WE are Equitable: Everyone’s participation and ideas are valuable.

We monitor our own time spent talking. We encourage others’ voices who we have not heard from yet. We recognize and value that people think, share, and represent their ideas in different ways.

We are Committed to our community: We learn together.

We come prepared to work toward a common goal. We have our own thinking to help us all learn. We listen carefully and ask questions to help us understand everyone’s ideas. We speak clearly and loud enough so everyone can hear.

We move our science thinking Forward: We work together to figure things out.

We use and build on others’ ideas. We use evidence to support our ideas, ask for evidence from others, and suggest ways to get additional evidence. We are open to changing our mind. We challenge ourselves to think in new ways.

And always remember, WE DO HARD THINGS.

Daily Participation Points-

On your report card, Characteristics of an Effective Learner scores are reflective of your ability to: Show RESPECT- We show respect for adults, classmates and property and being an active listener. Your CEL grade is also reflected on how well you show RESPONSIBILITY- by using time wisely and by completing assignments on time. Each day we will earn 2 participation points. One for Respect and one for Responsibility. If you follow the following examples you will earn 2 points. If you have a hard time being respectful or responsible one day, you will not receive the point for that lab session, but the next day is a whole new opportunity to be your best.

How to be respectful and responsible in our classroom: (How to get those points!)

LET’S HAVE A GREAT YEAR!!
