I Can Statements
- I can test my hypothesis by:
- Designing a reproducible experiment
- Carrying out an experiment with accuracy and precision
- I will know my experiment is of high quality if it:
- Is described clearly and accurately so others can reproduce it
- Has been carried out with accuracy and precision so that my results are valid
Suggestions for Assessing Student Readiness to Move Forward:
- Confer with students, asking probing questions about their experiment’s procedure to gauge how well it meets the quality criteria.
- Ask students to self-evaluate their work after completing one of the activities below.
Present students with flawed experiments and have them critique the design. Students can suggest changes to the procedure to improve the experiment.
Ask students to read their procedures to a partner and have the partner ask clarifying questions about areas where they may need more information. After they edit their procedure, they could go through the same process with teacher input as a rough-draft critique.
