- forward

]]> 2018-01-10 16:37:09 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220251921 Force? kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220252463 - more power
- harder push
- push or pull]]> 2018-01-10 16:38:00 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220252463 Energy? kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220253453 when you push it harder it uses more energy
-body energy?]]> 2018-01-10 16:39:34 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220253453 Put an object in the box kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220254459 - Car stops
- car "climbs" the box]]> 2018-01-10 16:41:00 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220254459 Speed kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220256165 fastness or slowness
Distance (how far)
----------------------------
Time (seconds)

Ex: 60cm / 1s]]> 2018-01-10 16:43:39 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220256165 Surface kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220258688 smooth table
carpet has tiny cracks and loose strings
better grip on carpet]]> 2018-01-10 16:47:56 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220258688 What makes it move is same as speed kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220260652 hand to car
wind to napkin]]> 2018-01-10 16:50:57 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/220260652 Variables that made the car go faster kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/221489765 -ramp down
-clear path
-books & journals, pencil box, cardboard box used for ramps]]> 2018-01-15 16:49:54 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/221489765 Variables that made the car go slower kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/221489800 -ramp up
-titled on one side, only two wheels touched carpet, bumping on the carpet
-running into obstacle]]> 2018-01-15 16:50:02 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/221489800 Does ramp material affect the speed? kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/221491200 2018-01-15 16:56:45 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/221491200 Materials you need for fire truck experiment kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/221775612 Boxes*
Books
Walls
Sticky Notes*
String*
Plastic tubs
Pencils]]> 2018-01-16 16:34:00 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/221775612 Pulls can be kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/224309485 Uneven
unfair
unbalanced
movement can lead to unbalanced pushes and pulls]]> 2018-01-24 16:45:06 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/224309485 How can gravity be a pull AND keep us where we are??? kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/227570970 2018-02-02 16:45:19 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/227570970 Movement doesn't always mean unbalanced?? kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/228202279 -going at the same pace without an extra push or pull
-batteries make the car move, but without a force (push or pull)
-moving together, but not getting closer together is balanced]]> 2018-02-05 16:29:42 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/228202279 Friction kmacdonell https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/232980842 Traction
car?  hands?
rub
smooth vs. bumpy texture
heat = more friction]]> 2018-02-19 16:36:46 UTC https://padlet.com/kmacdonell/fxn9uam0n3jg/wish/232980842
