This online ecology practical, from SAPS, uses random sampling to measure the abundance of various different species on an area of grassland.

Objectives

To give students practice at

• using random sampling to measure the abundance of various different species on an area of...

In this resource from SAPS, students learn about random sampling, diversity and different measures of abundance, before looking at close-up photographs of quadrats and using the field guide to identify them. The resources are intended to help students develop skills and plant identification techniques before going...

This online ecology practical, by SAPS, is designed to give students an opportunity to see how systematic sampling can be used to

• investigate changes in species richness across a footpath
• the distribution of species across a footpath

These online exercises are not intended as a...

This excel resource looks at various methods of evaluating pi, including Vièta’s formula and using the trapezium rule.

The first series of sheets include an introduction to François Vièta, his infinite product for...

Parabola

This file provides a well illustrated introduction to the properties of a parabola. It begins by illustrating the...

This excel file shows how Pascal's triangle can be used to calculate probabilities. Separate sheets show the possible outcomes when different numbers of coins are tossed. With the smaller number of coins these outcomes are listed.

In this resource from the DfE Standards Unit, students analyse simple number 'tricks', and explain how they work, using algebra. They then try to create their own variants of the trick, making it more impressive. Students will: develop an understanding of linear expressions and equations; make simple conjectures...

From the Association of the British Pharmaceutical Industry (ABPI), this interactive resource halps to answer questions that students have about the production of medicines and the careers available in the pharmaceutical industry.

There is a wide variety of questions on topics as varied as:

• The...

In this simulation students can see how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.

[b]Sample Learning Objectives include:[/b]

*Visualize and describe the photoelectric effect experiment.

*Predict the results of experiments...

This file has worksheets showing seven polar coordinate diagrams. The first allows students to explore simple polar coordinates by either inputting values for r and θ or stating those values for computer generated points. This is followed by two interactive sheets...

This engineering resource, produced by Mathematic in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can you predict future power requirements? Students are required to complete a table by substituting values into a formula and plot a graph. The activity offers good...

This excel program illustrates the effect of introducing bias when throwing coins.

The first interactive excel sheet simulates the outcome of throwing a coin ten times. The probability of each outcome is plotted and...

This series of interactive excel sheets explore the product moment correlation coefficient (PMCC). Another title can be found in our Virtual Textbook: Secondary collection.

This series of interactive excel sheets look at projectiles, either on or above the horizontal plane.

The first sheet defines the symbols and units used the remaining sheets.

This interactive workbook begins with a sheet which illustrate properties of odd, even and consecutive numbers. These properties are illustrated numerically and algebraically. The next two sheets deal with properties of the sum, difference and product of these numbers...
