What science ideas did you learn?

-average velocity

-average speed

-change in velocity

-motion diagram



How did you learn these ideas?

-discussing in class

-drawing graphs/tables

-learning to draw motion diagrams

-calculating averages




Why is it important to know this idea (What real world application is there)?

-It is important to know this idea so we can apply to other things we do in class and when we have to make up stories for homework and state testing.

-A real world example is when you are running the mile for gym and you want to find your average speed.

What science ideas did you learn?





-representation on a graph of slower and faster objects when they move


-we learned how to use in a table





-that things don't just stop, they have to slow down





-changes on a graph and how they relate to speed









How did you learn these ideas?




-drawing graphs




-testing with yellow car




-discussing in class



Why is it important to know this idea (What real world application is there)?

-It is important so we can apply it to other graphs we use


-A real world application is that when we try to stop suddenly but we have to slow down first.
