Mitten Science

Mittens keep our hands warm, but are mittens themselves warm? That's the question Selina Smith of the Classroom Magic blog posed to students in her mitten investigation.

Using inquiry science, students discovered that  mittens keep our hands warm because they trap our body heat, but mittens alone are not warm at all. Selina pairs this investigation with the book, The Mitten, by Jan Brett. Visit her blog to download the complete directions and handouts for the activity.


More Mitten Investigations
Selina's blog post intrigued me right away. I like her original question because it's easy to understand and can be explored with a simple science experiment. This activity also started me thinking about other mitten experiments that would be very easy for students to explore. A great follow up to her activity would be to have students brainstorm a list of mitten questions to investigate. Here are a few mitten of MY questions:

• Are thin cotton mittens as effect as thick thermal mittens for keeping hands warm?
• Do gloves keep hands as warm as mittens?
• Do hands get warmer the longer they are inside the mittens? 
• How does the outside air temperature affect the temperature of hands inside mittens? (If you are wearing mittens indoors will your hands be the same temperature as they would be if you were wearing them outdoors in cold weather?)

Designing Reliable Experiments

If your students are new to science inquiry, I would suggest choosing one experiment to do as a class. Later your students can choose another question to explore with a partner or a team. Download the Science Experiment Lab Write up from Teaching Resources before you begin.

To get started, give each student a blank copy of the form. Work through the various parts of the write up together, starting with the question and hypothesis.

Discuss how to design an experiment that will be reliable because this may be a new concept for elementary students. They tend to think that if they do an experiment one time, the results are "proof" that their hypothesis is correct. Experiments can be made more reliable by changing only one part of the experiment at a time (the variable), repeating the experiment, and measuring carefully.

After you design the experiment, let each team carry it out and record their results. Walk them through the remaining steps to draw conclusions and complete the science lab write up.

A Simple Solution for Fast Finishers

By Angela Watson, Guest Blogger

None of us will ever have a class in which all students work at the same pace. That's okay! The goal is to make sure everyone is engaged in meaningful learning activities. For some kids, that means providing extra projects and assignments while they wait for their peers; for other kids, it means teaching time management and how to get things done on schedule. This is not as difficult as it sounds! Predictable classroom routines, clearly defined procedures, and lots of positive reinforcement will make a huge difference in how smoothly your classroom runs.

An easy way to support kids who finish quickly is to teach your class to always look at a When Finished sign after they complete an assignment. The sign I use is posted on my board and lists several assignments I typically have students complete when they are done with their work early. I use a red magnetized arrow to point to the assignment kids are supposed to complete. If kids need to do more than one thing, I'll use two arrows, one which says "First" and one which says "Then" to specify the order things should be completed in. For example, sometimes I like to have students show me their work before they start their next project, so I'll move the arrow that says "First" so that it points to "Show your work to your teacher" and I'll move the arrow that says "Then" so it points to "Get your book box and read silently." The bottom portion of the sign allows me to write a customized assignment on the board underneath if needed.

The When Finished signs keeps me from having to write out the same tasks over and over, and keeps students from wondering what they should be doing. Students' time is never wasted...and I never have to hear, "I'm done! Now what?"

You can download the When Finished sign for free right here! Or, visit the Routines and Procedures page to learn how to teach other expectations, such as lining up, getting drinks, passing in papers, cooperative learning, and arrival/dismissal routines.

Christmas Paper Chain Connections Craftivity

I love dreaming up new seasonal activities, but I always try to make them educational. A few days ago I remembered how I used to love to make paper chains to decorate our Christmas tree, and I realized that this craftivity could easily be adapted to the classroom by having students write on the slips of paper first. In fact, this idea would fit perfectly into a lesson on making connections while reading!

Making connections helps the reader make sense of what he or she is reading, and we often teach our students about three different types of connections: text to text, text to self, and text to world. Children are often taught to recognize and distinguish between these three, so I created a printable to make it super easy for students to record and classify their connections. (For some great mini lessons on teaching connections, read Stephanie Harvey's book, Strategies That Work.)

You can use this activity just before the holidays and have students create paper chains to decorate their Christmas trees, or you can do the activity at another time during the year and make paper chains for fun. The Paper Chain Connections activity can also be used with a "reading marathon" right before the holidays. Everything is fully explained in my free holiday lesson packet called Christmas Decoration Connections. You can download it from my Seasonal page on Teaching Resources during December, or my TeachersPayTeachers store any time of the year. If you download it from TpT, please take a moment to rate it. I hope you and your students enjoy this activity!
