This week we are learning about push and pull, friction, and how to measure movement. When I saw this idea from Real Simple magazine (my FAVE!), I knew it would be the perfect fun for this unit!
So after I had these made, I gave all of the students a few marshmallows to eat....just to get that out of the way! The rest were STRICTLY used for Science!
We discussed and demonstrated that little force won't move an object very far (or very fast), but if you use BIG force, it will move faster and travel farther. Wow, they had fun practicing that with their marshmallows!
We also discussed how we can measure how far things move. We went outside and each student had a turn to see how far they could launch their marshmallow. We used a tape measure to record the results.
Push and pull....force....measurement.....what a fun way to teach these concepts!!
Oooh, what fun! I just "pinned" this idea!
ReplyDeletewhat?!?!?!?! I'm so jealous! This looks like so much fun and the kids seem to have had a blast!!!

can u tell me what cups u used i dod this and my cups kept bending or breaking, i love the idea but had trouble with the cups
ReplyDeleteThis looks like a lot of fun. I'm planning a unit on Force and Motion. I read msdeborah's comment and was wondering what kind of cups you used also...just want to avoid any difficulties. Thanks!
ReplyDeleteHi guys! I just used the cheap-o cups in the party section at Walmart (all sorts of colors to choose from!). And the regular size balloons. I did have to tell the kids not to squeeze their cups, it doesn't take much to get those marshmallows to launch. Good luck!
ReplyDeleteThis is amazing!!! Exactly what I was looking for to teach with my Force and Motion unit. Thank you so much. I LOVE how you integrated this with math.

What is a good substitute for the marshmallows? I thought cotton balls, but I think they won't have enough mass to them.
ReplyDeleteI would use cut up sponges.
Deleteping pong balls
DeleteI tried using plastic cups and it kept breaking. But paper cups worked well for me! Thanks for the idea!
ReplyDeleteI used a water bottle, it was so much easier. I cut the bottle in half keeping the spot end then attached the balloon (small side) over the spout. No need to cut the balloon or tie it. Easy Peasy!
ReplyDeleteThis looks super fun! I am definitely doing it. I just started teaching second grade in Spanish Dual Immersion and because this looks like such a hands on experiment, I don't have to worry too much about the children not getting it in Spanish. It looks very self explanatory!
ReplyDeleteif i were doin my son a science fair project what would be a good question (hypothesis) for this experiment
ReplyDeleteCan you please explain the purpose of the balloon attached to the cup? Is it for aire resistance?
ReplyDeleteNext week I'm starting the topic on simple machine and it's a great idea to start with push, pull and force. Thanks for sharing.
ReplyDeleteThis is awesome!
ReplyDeleteThank You! This was so helpful!
ReplyDeleteI've used paper towel tubes and they work well, too. And, we learned the longer tubes get slightly better accuracy.

ReplyDeleteI came across this during a speech pathology session for a one of my kids in their session and subsequently used this as a reward system for all my clients for the rest of the afternoon. Saying target sounds/words etc and then getting a go pinging foam dice ( my sustitute for marshmallows) at a target on the wall. Total success!

ReplyDeleteI did this tonight with my daughter using a red solo cup. At first I had cut completely around the rim and found it collapsed when I tried to put the balloon over. Second attempt was a success, I did not remove the entire bottom of the cup I only removed the inside leaving the bottom rim in place. we also made home made pom poms out of yarn. She loved it, thank you for the idea
ReplyDeleteThanks for sharing all your ideas and sites! Awesome!

Just as a warning--- a larger force does not move an object farther or make it go faster, it accelerates it more. I know this sounds like I'm nitpicking, but these language choices have big impacts later on in science. As a physics teacher, I am constantly correcting poor choice language my students learned when they were in elementary school.
ReplyDeleteAn object's speed is constant when the forces are balanced, in other words, the object going 5 m/s and the object going 500 m/s have the same amount of net force (zero)
The balloon is pushing, creating an acceleration. The bigger the force, the bigger the acceleration. This corresponds with Newton's 2nd Law and will correct a lot of misunderstanding of force from a young age.
