My 6th graders are working on changes of states of matter. When we do a lab activity, I usually write up all of the instructions for them. In this activity, because it was pretty simple, I explained the instructions and the students worked with their lab partners to write up the steps.
For this simple activity, each group gets an ice cube, a snack size Ziploc bag and an Alka Seltzer tablet. First students place the ice cube in the bag and seal the bag. I challenged students to see who could melt the ice cube quickest. Most students started by rubbing the bag between their hands and realized it was much quicker to stick the bag near the heater or run the bag under warm water.
After the ice cube was melted, I placed an Alka Seltzer tablet in the bag. Students QUICKLY zipped up the bag and made observations. After about a minute, the fizzing made the bag fully expand.
Students then wrote out the instructions and described the changes in states of matter that took place. We had a little bit of time left at the end of the period so the students brainstormed additional activities that we could try. Before the end of the period, we tried 3 tablets (the bag popped open), a crushed tablet (it dissolved super quick) and ice cubes mixed with water (the tablet took a long time to dissolve).

Enjoy! Have an awesome weekend!
Thanks for the wonderful feedback on my Transformations Foldable! I am so glad that everyone loved it as much as I do. I seriously look at it everyday. I swear I have a life.
So I have been lucky enough to have this ENTIRE week off. I can’t complain :) But when everyone is out of school in May and we’re still stuck in the sweltering building at the end of June, we’ll be even.
A few weeks ago, I introduced states of matter to my 6th graders, but between the science fair and health unit I had to teach, it has been a month since we first started it. When we get back on Monday, we are going to resume the chapter. To review what we had previously learned, the students will be making this foldable:
On the front I used glitter glue to show the how the atoms and molecules align in solids, liquids and gases. I think I am going to have the students use paint and Q-Tips instead.
On the inside, students will cut apart descriptions of each state and glue them under the corresponding flap.
In 6th grade, students clearly know the difference between the three states, but these are the characteristics that they really need to know.
Ooo new manicure!
Teaching states of matter? This can be adapted up or down depending on the grade level you are teaching. Click on the picture below to download the PDF. Just want the blank tri-fold pdf? Head over to this post here!
Hope everyone has a great weekend! I have big plans using this same template for a systems of equations foldable. Be on the lookout for it :)
