TEMI - Teaching Enquiry Mysteries Included

Timely prediction

This resource from TEMI introduces and explores a mathematical 'magic trick' in which the teacher predicts a random number that is generated by students using a series of number grids.

In order to explain the trick, students must use addition, tables and subtraction, as well as exploring number patterns and...

To dissolve or not to dissolve

This mystery explores solubility, ionic ...

Unreliable indicator

Students test crystal (alum) deodorants using either a red cabbage indicator or a universal indicator. The universal indicator suggests that the deodorant reacts as an acid, whereas the red cabbage suggests that the deodorant reacts as a base. What is happening here?

This resource can be used with different...

What happened to the cup?

Students investigate why some plastic cups collapse when filled with hot water and some don't.  They compare the effect of hot water on a range of cups and relate their findings to the properties of the plasticsused for each cup:  whether it is biodegradable or not, its melting...

Why did mammoths become extinct?

Why did mammoths become extinct? Scientists have presented two claims: climate change or human hunters. In this lesson students apply their knowledge of evolution and study evidence to decide which claim is best supported.  Students are also asked to explain how a change in the environment can leave a...

Your numbers divided

In this TEMI resource, a mathematical 'magic trick' is used to explore divisors, prime numbers and prime factorisation.

In the trick, the teacher invites students to type a random three digit number into their calculators. To make the task of predicting the divisors of this number even more difficult,...
