This unit - Lesson is all about experimenting and forming an hypothesis. Hypothesis statement--a prediction that can be tested or an educated guess. In a hypothesis statement, students make a prediction about what they think will happen or is happening in their experiment. The unit can be developed around ELA rhyming through "Humpty Dumpty". There are numerous class and group project experiments and a rubric worksheep around one of the experiments, but anyone of the examples can be used - my children and teachers that I have trained on HOTs loved this activity.
