STEM Activity #1: Cranberry Towers
Cranberry towers are perfect for reviewing measurement as they try to build the tallest towers. All you need are fresh cranberries and toothpicks. I also use cranberries and toothpicks with kindergartners to review shapes.
STEM Activity #2: Cranberry Bog Boats
One of the NGSS focuses is to make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and into a new object. This is a perfect opportunity to use the cranberries and the toothpicks again. We design and build bog boats...yes bog because that is where the berries grow and are harvested. This is perfect for connecting a bit of cranberry information.
We use the following video to connect our boats and find that not all boats will float. We then make observations and gather evidence as to what floats best. (it also gives some really great information about the plant and we tie it into native american lessons along with pemmican which was eaten by Wisconsin First Nations)
Science Idea #1: Sink or Float for Littles and Bigs
First off, our students eat craisins at breakfast fairly often, so I figured when I showed them a cranberry they might know immediately what I was holding...was I wrong. Here, we live in a state that produces more cranberries than everyone and our students don't know what this native fruit is. I heard grapes and raspberries, but not one said cranberry. We predicted what would happen if we put them in water, then I demonstrated. We then opened them up to see why they floated. They have air pockets! We then tried a variety of different fruits and vegetables to test their buoyancy . This concept is great for any age! Cranberries can be a perfect fall springboard!
Science Idea #2: Cranberry Juice and Chemical Reactions
I found this video a few years back and I have been using it every year during our FOSS Mixtures and Solutions Unit every year since. Using Cranberry juice as well as vinegar and lemon juice can create a perfect activity to talk about acids and bases.

Just in time for that Thanksgiving week lessons...both fun, engaging, and educational!
