Geography, Science, Math, and Pumpkins...OH, MY!

You know how little ideas get started in your head?

As I was browsing for ideas in the classroom, I found this idea on Pinterest: Pumpkin Globe. I immediately shared it with my teammate, who loves all things social studies and he really wanted to do it! I suggested that he ask a local vendor if they could offer pumpkins at a reduced price. He pitched it to our principal, who was able to get them for the social studies classes. Each of our seven 5th grade classes got 5 pumpkins so that those teachers that teach social studies (not me) could have students paint the pumpkins in groups. I was so excited to see the finished product! Here's a shot of a few:

Acrylic paint turned out to work best. 

So, to go backwards for a moment, I teach science. When I found out that our school was going to get the pumpkins, my wheels started turning. Sitting next to my husband one evening, I said, "We should launch pumpkins." Of course, my husband looked at me like I was crazy and I knew the idea was at least half crazy and would probably never get approved. It was at that point that I shared my idea with my colleagues and at least two of my colleagues thought I wasn't crazy. In fact, my one teammate took it as a challenge and asked her husband if he could build a catapult. Two of us went to the principal to pitch the idea, pretty much thinking that we were going to be told no. Perhaps it was the idea that we would be taking a geography project and turning it in to a math and science project, but, guess what? Our idea was approved! Three weeks later, we were ready for launching! 

Here's our catapult. As you can see, we have a colander on one end, and the other end has a handle on each side so that students can each grab one side of the other end, and then use their strength to launch the pumpkin. 

My teammates did a practice launch in the morning, just to be sure all was well. 

Back in the classroom, we told the students about this lab, as we had kept it a secret up until that day. As you can see, I bought a few additional pumpkins so that we could compare different sizes and the distances that they would each travel.

"No, don't chuck them! They are too young to die!" one of my students said about the baby pumpkins. 

We weighed each pumpkin by having a student stand on a scale and get his weight, then get back on the scale with the pumpkin. Great review of finding the difference! The data sheet that I created had room for data for five pumpkins, so after weighing all of our pumpkins, we chose 5 that were different in weight, and decided that we would use those for our data, but still launch the rest for fun.

Students had to form a hypothesis by telling which pumpkin they believed would go the farthest distance and which they believed would go the shortest distance. We launched the heaviest and the lightest first, recorded the distance, and then students estimated the distance of the remaining pumpkins before we launched any more. When the five pumpkins that they were recording data for had been launched, I allowed the students to launch the remaining ones for fun. The farthest distance we had was 41 feet! Here's some action shots:

Preparing for launching

My co-teacher and I decided to give it a try! 

Here's one from start to finish:

Yup, this one smashed!

We did talk about how our data could not be completely reliable because each group did not necessarily use the same force and we were changing the sizes, which violates the rule of having just one variable per experiment. However, students had great discussions about that alone as they talked about how they could do this lab differently in the future. 

I was thrilled with this whole lab for so many reasons, but mostly because my amazing team and I worked together to make this happen for our students. I'm blessed to have colleagues who helped to make this happen, and even more blessed that I have a colleague with a handy husband! I know that this is an activity that the students will never, ever forget and that a great time was had by all! 

If you are feeling brave and want to try this in the future, I have placed my 4 page lab on Teachers Pay Teachers at Pumpkin Launching Science & Math Exploration. It does not include directions for building the catapult, as that is not even remotely my field of knowledge, but you can google it and find zillions of ideas for creating a catapult that works for you! 



Questioning Ideas & Resources

We just wrapped up a two week focus on questioning. I've been using The Homework Machine by Dan Gutman as my read aloud and my students love it. They are so curious about "Milner" and the book has naturally lended itself to questioning. As a class, we've created five chart papers full of questions! We spent the first week of questioning focused on becoming aware of questions that we have before, during, and after reading. I made question mark cards for them to hold over their heads when they wanted to share a question, and those cards just kept popping up! It was awesome!

These will be a part of a set that I plan to post later this week.

The next week, I worked on thin and thick questions. I gave them a "skinny" question mark card on a different color of card stock. Then, when they had a question to think-aloud, they had to hold up the right card. This was challenging at first, but after talking through a lot of examples and modeling daily, I can say with confidence that my students are now questioning wizards!

To follow up after whole group practice, the students used "Roll a Question" cards that I printed on card stock I made 5 different cards, with thin and thick questions in 3, and a mix of both on the other two. My students used them during buddy reading, guided reading, and even for independent reading. They are so easy to use...all you have to do is add some dice and you've got students excited about questioning!

Don't these look fun to use? Well, I've got great news? I am posting them on TpT as a freebie for a limited time! Get it Here: Roll A Question

Get them while the getting is good! 

Oh, and don't forget to enter the giveaway and share it with others! I'm choosing not one, but two lucky winners!
