Messenger KWL for Science by Jonathan Messenger https://padlet.com/messj89/7cp578cpdsaq (K) List 5 things that you know about the unit (W) List 5 things you would like to know/find out (think bigger questions) en-us 2018-02-06 17:31:15 UTC 2026-01-15 17:47:19 UTC hello@padlet.com systems in action - mind map https://padlet.com/messj89/7cp578cpdsaq/wish/228784522 1. an example of a simple system is a pulley or lever.
2. systems are a big part of our world.
3. systems have hundreds of uses .
4. systems make our lives easier.
5. many systems make us able to work faster.

want to know:
1. what makes a system a system.
2. what makes a system go.
3. who invented the pulley.
4. where is a lever used in our daily lives.
5. is a button a system.]]> 2018-02-06 18:43:27 UTC https://padlet.com/messj89/7cp578cpdsaq/wish/228784522 Systems in Action Mind Map https://padlet.com/messj89/7cp578cpdsaq/wish/228784600 By: Leana, Geraldine, Olivia, Hannah

- Inertia: Resistance to motion
-One of Newton's three laws: Objects don't like to change what they're doing but they stay doing what they're doing until a force acts on it.
-there are multiples types of energy ex. kinetic energy potential energy 
-Another one of Newton's laws
For every action there is an equal but opposite reaction
 
5 things we want to know:

what type of work is ideal when it comes to making structures?
How might potential and kinetic energy work together to make work easier?
what material would be ideal for preventing concrete from cracking.
to under stand more of newtons laws.
