These are super cute and easy to make!! One concern is that the very young students might be distracted by them on their desks, but they could just lose privilege of having them if they were touched? It would be an interesting change also if the “critters” went into the bucket when it was quiet for the whole class – and how many they got each day could earn the whole class something.
Science can be very exciting, if you allow it to be! This website shows the multitudes of experiments that very young students can engage in. (http://leftbraincraftbrain.com/2014/08/20/stem-for-preschoolers-love-learn-linky-6/)Many people believe that science is too complicated for the early elementary or preschool age, but it is just about the complexity of the content. The “apple browning” one seems like a great incorporation – the students can monitor how fast it happens, come up with ideas for why it happens, and it is something they see all the time! Everybody has eaten an apple or seen someone eat an apple. I want to make learning as engaging as possible, and involving science in such a basic, but effective, way is achievable.
