Science - Resources of the week

How science works: four of the best

The popular resource offered by sianiews is a PowerPoint presentation with 11 slides highlighting key words and definitions for terms such as categoric variables, systematic errors and reliability. Change the school name, print it off, laminate it and display it in a prominent position in your lab.

Clairemcgurk offers a fun PowerPoint-based activity based on a robbery, where new evidence is presented that encourages students to hypothesise about who did it. "How science works - evidence" is mainly designed for key stage 3, but could be used at any level because it can trigger useful discussions regarding public understanding of scientific evidence.

"How science works: can we believe the claims?" is a Nelson Thornes-produced activity pack from the GCSE Kerboodle course. This provides a worksheet and a teacher answer sheet and investigates the claims for a cholesterol-reducing spread.
