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 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.
...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 resource contains four excel programs with interactive spreadsheets dealing with topics relating to quadratic expressions, their graphs and solving quadratic equations.
...
This engineering resource, produced by Mathematics in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can production outcome data from a manufacturing process be analysed to optimise the process? Students consider the outputs of resistors to see the outcomes form a normal...
This contains two excel programs with interactive spreadsheets designed to show the graphical solution to pairs of simultaneous equations and provide their solutions.
...
This interactive excel program is about finding the equation of straight lines in the form ax+by+c=0. The first two sheets deals with the equation of the line through two given points and the equation of the line through a point perpendicular to a given line. The...
This animation shows the major stages of subcloning. This is the process of breaking up fragments of DNA from BAC clones into smaller more manageable pieces for DNA sequencing. This process was very important during the Human Genome Project. Subcloning involves several standard molecular biology techniques...
This interactive excel program allows students to explore the relationship between the transformation of functions and the associated graphs. Functions explored are straight lines, quadratic and cubic functions as well as sine and cosine curves. Each type of function...
