Make Solids, Liquids, and Gasses fun by Making Butter!

Some of my FAVORITE things come from Pinterest! One day, as I was looking around aimlessly, I ran into a post about making butter from {Cinnamon's Synonyms}. I thought, oh that's pretty cool, so I shared it to {Taking on Second's Facebook} page. I had SOOOO many comments about how easy it was and how much students had liked doing it! I decided to give it a try!
We started by talking about the states of matter: Solids, Liquids, and Gasses. 

We practiced seeing how gasses take up the space of the containers they are in by blowing up balloons of different sizes. 

Cassondra, my teaching partner from {Primary Scribbles} had been saving baby food jars. She found enough for both of our classes!
If you can't use baby food jars, it is just as easy to make a class size batch in a mason jar, or any clear container with a tight lid. The one with the white inside is salt. We thought it would taste a little better with a pinch of salt.

 I filled the jars about half way with heavy whipping cream from Wal-Mart.
We listened to how it sounded in the jars as we started to shake. Some of the jars started to leak a little, so we just put them inside a baggie. This completely took care of the issue! 
Then it was time to get serious...
We logged into {Go Noodle}, and Whipped and Neigh, Neighed that heavy whipping cream until it started to become solid! It took a lot of shaking, but we paused the video to listen to our jars every few minutes. 
Once we began to be able to see through the jar again, we shook the jars through the Cha-Cha Slide, to be sure they were done. The students noticed the change in sounds their jars made.  I had never done this before and was not sure what to expect! When we opened the jar, it looked..well just like butter!
I don't really like butter unless it is inside food or on my potato, so I didn't really try it. The kiddos took full responsibility for that! 
The ones who ate their bread and butter LOVED it! They said it was really good! I'm pretty sure this will become a yearly experiment before Thanksgiving Break!


*Gasp!* What happened Mrs. Rigsby!?!

Ohhhh I have been wanting to tell you all about what we have been doing the past two weeks! Cassandra from Primary Scribbles and I have been doing book clubs to finish up our school year. We love introducing the kiddos to mysteries! I went searching for mystery books in 3rd and 4th grade rooms. Luckily, was able to find 3-5 copies of a mystery book, enough for the whole second grade!
Cam Jansen is our go to for mysteries! "Click!" Our students read their books for 10 minutes a day. Then they would fill out their case file and mystery journal that summarized what they read. We used {Amy Lemon's Mystery Mini Unit}. I just love all of her awesome activities, and so do the students! 
To wrap up our mysteries, we decided it would be fun to let the kids be the detective! Earlier this year, we attended the {high ability conference}in Indianapolis. They told us all about this STEM activity and gave ideas on how to set it up. 
I headed to Wal-Mart to get the snacks and equipment we would need to set the mystery up!
Equipment:
Soft brushes: I bought some make up brushes but you could probably find soft paint brushes too!
Cocoa: This is for the dusting
Flour: Used to make good footprints
Snacks: or something that is stolen or eaten
Lotion: to give you "sticky fingers"
When I got to school, I took everything out of the bags and set it in plain sight of the kids. As they walked in, they saw this spread of snacks and drinks. Of course, I told them it was for Field day, which was the following day. We went about our morning and they went to special. As soon as they were gone, the fun began! 
I sprinkled chip crumbs and Oreos ALL over the floor, even on one student's desk! I just made a huge mess!!! It was the most fun for me, throwing food everywhere!
I spilled the flour, which was for a science activity(not even a lie!) and put some juice on the floor. Then we headed to get our "criminal."We had our Title One teacher put on some lotion, and touch everything! She also put her feet into the flour and walk right out the door. I added some caution tape to spice up the scene too. 
Then the kids came back.... 
They were totally freaking out!!! I loved it! Once I finally got them settled down(10 minutes or more, not even kidding!), we made a list about what we knew about the crime scene already. They were very observant, mentioning the shoe prints, ring on the table from a cup, and the directions of the footprints. I did a little leading to fingerprints, but not much! I showed them a {YouTube video} about a crime scene similar to ours. We stopped it after the finger print part. Then I demonstrated how to take fingerprints. We used only one finger because we would need to practice taking off a small part of the finger from our evidence. Doing our own finger first was good practice. 
To take fingerprints:
First we wiped our desks off with a Lysol wipe and let it dry. We didn't touch our desks until we were done fingerprinting. Then I drew a small box with a dry erase marker on the students' desks. That was where they were going to put their fingerprint, so they couldn't misplace it. 

We used lotion to get our fingers oily, don't rub it in completely. The students put one finger in the box, when we do it next year I will have them do their whole hand too. Then I passed around my make-up brushes and cocoa for students to dust their prints. 

They don't want to rub the prints, just kind of stab at it with the brush. You will have to blow the excess cocoa off the print, and your room will smell like Willy Wonka's Factory! It's amazing! I passed around my tape dispenser and the students rubbed a piece of tape over the print. 
They took off the tape and put it on a piece of construction paper I had ready for them. Then they labeled this their print. 
We passed around our magnify glasses to look closer at the ridges and waves in our prints. 
Then it was time to do the same to our evidence! I told the students, who were in their mystery groups, that they would go out into the school group by group to fingerprint a couple teachers. I gave each student in the group a job. 
The jobs were: 
1. iPad photographer: 
2. Holder of the suspect list
3. Finger printer
4. Duster

The photographer had to get a good picture of the scene and of the footprint. They took the iPad around with them to compare shoes. Then the finger printers came to get the prints from the evidence. They were chosen as finger printer because they did the best in their groups taking their own fingerprint. 
Each group took turns going out into the halls to do their jobs. We did notify the staff ahead of time, so they were expecting the kids to invade their classrooms. The duster held the lotion, just in case, and each finger printer carried white construction paper to place the print. 
I'm so grateful our staff is so cooperative with it comes to things like this. Second grade is not a quiet, calm class, but they sure did a great job! After all the teachers were fingerprinted, we came together as a group to talk about the shoe prints and fingerprints. They narrowed it down to two teachers, one was even the right one! The shoes really helped us figure out who the culprit was. The kids loved getting to take the role of detective! We did a journal entry on what they learned from their mystery books and from being the detective themselves. Most agreed, it was a tough, but fun job. 
Now if only the teacher could have stayed out of the evidence for lunch...Good thing they didn't catch me! I would have been in trouble!



STEM: Peep Mobile

Whew! Moving into a new house, without Internet, sure takes a lot of time! I finally have a chance to blog since we are literally watching the grass grow! For Easter, my sweet mother makes us Easter baskets full of goodies! This year we had a bunch of Peeps...like five packs! So I took them to school and made good use of them!
We took a page from Smart Chick to set up our Peep Mobile race. I had to cut all our cardboard pieces before we could begin. 

Supplies:
Peeps
Lifesaves(Wintergreen sure makes the room smell good!)
straws
1 Peep wide piece of cardboard
tape
scissors
one piece of printer paper
I had the kids gather their supplies. They didn't get a Peep until their car was done. Then it was time to lay down the rules!
Smart Chick has the easiest, kid friendly directions to post in the classroom for students to review! I loved that they kept going back to check the challenge rules while they were working. 
The Challenge:
Students were challenged to create a mobile that would hold a Peep and go the furthest in three puffs of air. We practiced filling our lungs and getting the most air in one puff. I gave students 30 minutes to design and make their mobile. They worked really hard on their designs. 
One issue some of the kiddos were having was keeping the "wheels" on the straw. This was about the only problem that arose in the designs. I tried to give them a hint, but I also wanted them to figure it out themselves. 
My room was full of little engineers! 
Then it was time to start racing! I had 5 or 6 kids race in the hall at a time. They had a starting line their mobile had to be behind. When I said go, they had to do three puffs of air to see how far they could get their mobile.
Some went crooked, some didn't go at all. There was one that went pretty far down the hall considering they only used three puffs of air. You bet it was one of the kids that is just full of hot air to begin with! 
Then there was this one...
He said, " You always tell us to do our best, so I did!" 
This was a fun way to spend our Friday afternoon. The kids look forward to their weekly STEM project every week. They come in on Monday asking if we can do science this week. I love that they get so engaged in our STEM activities. 


Building Bridges with Index Cards

We got a little index card crazy today! The kids were challenged to build a bridge using only index cards and scissors, stuff we all have just laying around the classroom! We used the STEM pack from Teachers are Terrific.
First, we did some mini experiments with one index card and markers to balance. This was so the kids could understand the weight of one penny compared to ten or more.  Students did some preplanning for their own tower next!
I pulled sticks to put them in groups. I gave them fifty index cards and set the timer, which I later found out wasn't needed. Their bridge had to support at least ten pennies and be built across two reading books. 
These guys had accordion folded some index cards for the bottom. Then they tore their index cards to make the top part! Pretty smart I thought!
They were the first ones to accomplish the task!
They had to then tell me why their bridge was a success. The ones who couldn't quite get it figured out had to tell me why it wouldn't work.
I think it was really because they went a little folding crazy! This was such a fun activity. The groups that succeed were not the ones I expected. The ones who I expected to get it right away, never did get their bridge to work! It was a great way for students to show off their skills that aren't always utilized in the classroom. I loved it!


STEM with Gummy Pumpkins

While looking around on Pinterest, of course, Cassondra found this great STEM activity for us to do during Fall Parties! Click here to read the original post. Students started with finding a game plan.
I did not create this page.
We were going over this page while I was carving the tops off of pumpkins. This was my way of getting an extra 20 minutes to finish them up! Students were challenged to build the tallest tower with a box of toothpicks and one tub of gummy pumpkins. I randomly chose students to be in groups and they got to discuss their plans together. Then I set the timer for 20 minutes and let them go!
Some students had great ideas of working on a base, because it's all about that base you know;) As I walked around the room, I saw and heard several different different ideas. The students were not as confident in this tower as they were in our cup staking challenge

This tower was a mess of tower, but would stand on its own!
This group was getting the right idea! 
These guys were working separately to create their own towers to put together.  Overall this activity was a little bit of a bust for my class. They enjoyed trying, but no one was very successful. But by the time they were done, so was I with the pumpkins and then the bigger mess began!



STEM:Cup Stacking

This week, I challenged my students to build the tallest tower with forty cups. The cups we used were punch cups. That is all you need! Such an easy, fun, engaging activity. My students loved it!! I set 20 minutes on the Class Dojo timer. I used the random chooser to assign groups. There were 5-6 students in each group. Then I yelled " Go!"
At first, all the groups wanted to make a pyramid with their cups. That was just not going to get them very far. I didn't want to give them guidance, but I needed to give a tip to get their brains working in overtime. 
They were done with the task in less than five minutes with the pyramid way. Then I gave them the idea to turn their cups around and wow! They just took off!!
They went higher and higher! I walked around listening to the groups work. I heard, some say, "Stop being bossy!" " You need to listen to me!" " I don't wanna work with you." and my favorite " Don't breath!"
I don't usually leave my kiddo's faces in the pictures, but just look at the fear, the wishful thinking, and the worry on the kids in the background! It is priceless! 
These two boys were neck in neck with each other. They both have a leadership attitude and had a hard time getting along as a group. 
The winning group had a tower 52 inches tall! I was so proud of my kids for tackling the challenge. 
We did the stacking challenge twice. The first, I picked the groups randomly. The second time, I picked team "leaders" who chose the rest of the group. There was a lot less bickering when I chose the random groups. I think everyone had a good time and learned a little something about working as a team. 
They were trying not to breath on the tower...
