1. In groups of 3 - 4 students, read the following article from The Conversation 11 April 2016 2. Using the Cornell Note-taking Method, create notes, summaries and questions (under keywords and comments) about this article.
3. Within the group, analyse the article by collating the questions, facts and figures from each group member.
4. Brainstorm together to create a
Kahoot! about the content. Make
sure you look at the science around diatoms.
5. Share with your classmates and play one or two of their Kahoots!
A single strand of hair may now help catch the criminal! Secondary Australian Curriculum General Capability: Literacy Cooperative Learning Activity
1. In groups of 3 - 4 students, read the following article from The Conversation 8 September 2016 2. Using Plus, Minus & Interesting Strategy, analyse the article and answer the questions: a. What have you, as a group, learnt from this article? b. What is the Chemistry behind this discovery? Describe in detail. c. What are the limitations? 3. Using the Expert Jigsaw Strategy, divide up the following article from The Conversation and using PMI again, share with each other the Forensic Science within the article: The Conversation 13 December 2021

Curriculum General Capability: Literacy Cooperative Learning Activity
1. In groups of 4 - 5 students, you are going to make measurements of your feet and record the results. Look at the following diagram and work out together how you will create a table showing the results of foot measurements for each student within your group. Add these results to the class table.
(Source: Science Direct) 2. Using A4 or A3 blank paper, draw an outline of your feet - both feet. 3. Make the measurements above - pte to d5.t etc and record the measurements. Add to the class table - put your initials next to your results.
Was there a difference between your
feet size? Was it significant? How can you tell? 4. As a group, you are going to measure your heights. Put them onto the class table making sure that the foot size and height are linked. 5. Add your shoe size to your class table. 6. Results a. put the class results on a graph. Is there any correlation? b. work out the correlation and ratio between foot size and height. c. work out the correlation between shoe size and height - are there any differences that are significant?
Real World Application Most people at a crime scene have their shoes on!
7. As a group, investigate the following table carefully: You will note that for height range you need to convert feet and inches to cms. (Source: The Anatomical Record)
Table I. Relationship
of foot length, shoe size range, height, and percentage of adult males with
feet and shoe sizes in each percentile.
8. What interesting facts did you discover as a group? 9. Compare and contrast your class' foot and height table with Table 1. Are there any discrepancies? 10. Look at the following shoes found at a crime scene. Work out the approximate height of the owner. Are there any other identifying marks that will help a forsensic scientist or investigator?

Students examine real-world case studies of probability being applied in
misleading ways. They assess and explain the flaws in the mathematical
methodology used.
