Display slide 9. Have the students identify the complimentary ‘er’ words in the list. Begin a discussion about other ‘er’ words which could be used to describe the state of something in a scientific investigation.
Display slide 10. Explain to the class that they will be developing a hypothesis for an experiment they have been researching. This could be something that is already in progress or something the students have worked on in past lessons. To help those who may be having difficulty, display slide 8 from the presentation as a scaffold.
Gather the class to discuss the statements which have been formed. Encourage the students to share their hypotheses and discuss whether or not the hypothesis:
can be tested scientifically
explains a claim or educated guess clearly
uses the ‘two -er’s’ system (this is not compulsory, just a handy system).
Encourage more confident students to develop multiple hypotheses.
Support students who require further assistance in developing a hypothesis by allowing them to verbally discuss their ideas with an adult.
