squeaks and I had an interesting adventure this morning last night it was snowing when we went to sleep and when we got up today there was a bunch of snow on the ground and there's this great hill in the park behind the fort and squeeks wanted to go sledding so we went out there pulled our sled to the top of the hill and pushed off we started to move a little bit but then before we could get very far we stopped now I don't know about you but to me that seems like kind of a silly sled ride we barely moved before we got stuck in the snow what do you think squeaks yeah what was kind of disappointing but even though our sled ride this morning didn't work so well I bet we can find a way to have an awesome sled ride when we go back to the park because with science we can figure out why we went so slow and how to get ourselves zooming down the hill instead when we're sledding we want to move forward as fast as we can and there are a couple of easy ways to help ourselves do just that one thing we can do is push off really hard at the top of the hill to give ourselves more speed right from the start we can also have more weight on the sled which will keep us going for a longer before we stop like how it's much harder to stop a heavy bowling ball that's rolling towards you than it is to stop a lighter soccer ball that's true squeaks we were already doing both of those things this morning we pushed off really hard at the top of the hill and with squeeks and I both on the sled there was plenty of weight to keep us going but that wasn't enough we still didn't move very fast and we stopped pretty soon after we started moving and that's because there was something that was slowing us down it was pushing back on us and stopping us from moving forward something that pushes her pulse is called a force and the force that was stopping us from zooming down the hill is called friction friction is what makes it hard to slide things across each other there's lots of friction if those things are rough and less if they're smooth have you ever noticed that when you're wearing socks it's much harder to slide your feet across carpet than it is to slide them across a wood floor that's because of friction carpet is pretty rough so there's more friction between your socks and the car but then between your socks and the smooth wood the force of friction pushes hard against your socks as you try to slide them across the carpet and the same thing happened with our sled squeaks our sled is made of wood so it's pretty smooth but the fresh snow from last night is still soft and powdery and that was making it hard for a sled to slide across it instead the snow kind of bunched up underneath us and there was lots of friction slowing us down after we pushed off and that's why we didn't go very fast or far before we stopped so squeaks if we want to go really fast next time what do you think we should do well that would be one way to do it we could wait a few days until the snow on the ground is much more packed out so it'll be hard and smooth but we could just pack it down ourselves right now we can go back to the hill and stomp on the snow for a while then smooth it out to make a nice track of hard-packed down snow for our sled it'll be a little more work before we can start sledding but I think it'll be worth it how about you squeaks okay let's do it wow that was awesome we went back to the hill with our sled and ran around on the snow for a while to pack it down into a smooth track then we went up to the top of the hill pushed off and zoomed all the way down to the bottom with a smooth hard snow there wasn't as much friction pushing back on the sled after we pushed off so we kept going faster and faster yeah let's go do it again thank you for joining us if you want to keep learning and having fun with squeaks and me hit the subscribe button and we'll see you next time here the board
