This is an easy science experiment to do with early science learners. The packet was developed to use as a tool for students to make observations and predictions as to what will happen when grapes are put into the sun.
For this project you will need grapes and a sunny place to put the grapes. It should take about a week for your grapes to transform into raisins. With this activity you can also discuss with your students physical change. I recommend using this for K-1 students.
