What is science? Science is a way of knowing, a method of learning about nature. Rooted in common sense, its formal, systematic method is called scientific inquiry. In doing scientific inquiry, scientists use a variety of empirical approaches, techniques, and procedures to collect data from nature, examine and...

This Nuffield task is to design an emergency shelter, using a 4m x 3m rectangular piece of tent material, to protect three people from wind and rain.

The key processes developed include:

This SMILE resource contains two packs of games, investigations, worksheets and practical activities supporting the teaching and learning of equations, from solving simple linear equations to solving Diophantine problems.

Equations pack one contains fifteen work cards with a wide variety of...

This lesson develops the concepts of estimating the lengths of everyday objects, and converting between decimal and scientific notation.

An introductory activity looks at converting between decimal and scientific notation.

The main activity involves a collaborative exercise centred around picture...

This is a problem solving lesson, designed to help you assess how well students are able to:

• Model a situation.
• Make sensible, realistic assumptions and estimates.
• Use assumptions and estimates to create a chain of reasoning, in order to solve a practical problem.

This lesson develops the concepts of length and area. Particular attention is given to proving why two areas are or are not equal.

The lesson begins with three questions regarding area that students must classify as ‘sometimes, always, or never true’. An example is ‘if you join the midpoints of the opposite...

This resource develops the concept of substitution of integers, fractions, decimals, and directed numbers into inequality statements in order to test their validity. Students also represent inequalities algebraically and in words.

An initial question that students work on is representing the statement

This lesson develops concepts relating to radicals. In particular, students will enhance their understanding of:

• Use the properties of exponents, including rational exponents and manipulate algebraic statements involving radicals.
• Discriminate between equations and identities.
  In this...

This lesson develops the concept of reasoning about the properties of rational and irrational numbers. In particular, students will enhance their understanding of:

• Finding irrational and rational numbers to exemplify general statements.
• Reasoning with properties of rational and irrational...
