It depends on the age of the students. We run sessions for between 1 1/2 – 2 hours depending on the age of the students. Ideally we would offer a minimum of 2 sessions, the 2nd session the following week. We have modules which run for 2 – 4 weeks per class, aligned to your Science OR Enquiry unit with an assessment rubric aligned to your reporting outcomes. These start at $10 per hour per student ie a 3 week x 2 hour session = 6 hours OR $60. This is our most popular model with our schools.
