Hey Science Friends,
I had a special request for this activity re post and I was happy to write about it considering that we just finished our unit on Force and Motion. One of my favorite culminating activities for this unit has been Kick the Can! The Kick the Can activity is the perfect activity to review Force and Motion and Position and Location terms with developing young scientists. All of the items needed for this activity can be found at any local store.
I used the recipe above for one batch of ice cream. I added extract to flavor the ice cream and when we were finished we added candies on top. The candy and extract are optional. As a special note... I have made this recipe several times with Kinder kids but just simply due to time and everything else in the classroom I also make a few batches of ice cream in a small ice cream maker to take to class. The only reason I have done this is because one or two batches of ice cream in the cans is just not enough ice cream for the entire class. I have found that making one batch and tasting it as soon as it is ready works great but the ice cream is soooo good we always want a little more. That is the only reason I make a little ahead of time. The science in this activity is the activity itself and the children need to be involved in it.
After the cans were prepared we were able to keep the cans moving while using Positional terms such as above, below, behind, in front of, beside, inside, outside, between, right and left. To review Paths of Motion we kept our cans moving in a straight line, zigzag, up and down, back and forth, round and round and fast and slow. We had such a good time with this! This would also be a perfect activity to discuss freezing and melting because the can does get cold and forms crystals that are wonderful for investigating with magnifying glasses! Oh and think of the notebooking...
This is what the mixture will look like as it freezes. Your freezing time will vary based on your ice and rock salt mixture. This is one reason why I suggest a batch or two made ahead of time because you may need to freeze this soft serve mixture in the freezer and who wants to wait to taste it after all that work? Another tip... get your cream and milk as cold as possible before you start. I added mine to the freezer before we used them.
And here was our Kick the Can ice cream. It was soooo good and now you know why we wanted more! I hope you and your class have fun with this just like we did. And if you are looking for more fun with Force and Motion...
Have fun investigating Science friends!
