Computer Modelling & Data Logger
- Computing modelling and using a data logger are essential in all scientific experiments for obtaining and analysing reliable results
Data Loggers
- Data loggers are a tool that allows for the quick and efficient gathering of data
- The information contained within a data logger can be inputted into a computer and formatted into a table
- After this is done the computer is able to calculate the average and plot graphs using the data and calculate gradients which quicker and more accurately than humans
- They are electronic devices that automatically monitor and record environmental parameters over time such as temperature, pressure, voltage or current
- It contains multiple sensors to receive the information and a computer chip to store it
A data logger measuring and displaying temperature using a probe
- The benefits of using data loggers and ICT (information and communication technology) include:
- Readings are taken with higher degrees of accuracy
- Reduction of human error (eg. human reaction times, subjectiveness)
- Readings can be taken over a long period of time eg. hourly readings of temperature over many days
- Readings can be taken in a very short period of time, which would be too quick for humans to see a difference
- Reduction in safety risks with extreme conditions such as measuring the temperature of boiling water
Computer Modelling
- Computer modelling is commonly done in conjunction with devices such as a data logger
- Modelling is about processing the data collected from a physics experiment into software or a spreadsheet
- Graphs and charts can be generated from a table of values
- These can then be exported to a scientific report
- One of the benefits of these computer programs is that time can be sped up to predict the future outcome of an experiment
