Measuring your heart beat rate over a period of time (Cardiograph)

Monitoring your temperature during an infection.

Scientists: Take readings during an experiment to see how something reacts.

Environmentalists: Take reading of pollution levels to monitor the air/water quality.

Noise pollution around an airport.

Seismic activity under ground – investigating earthquakes.

Learning Intentions:To learn how to take readings using a data logger.To read the data onscreen and explain what the readings are telling you.

To collect data remotely and download it on to the computer.

To label graphs correctly to inform the reader.

To interpret the data you collect and draw conclusions.

Datalogging :Worksheet 1: Meters

Use the data for clapping.Write or draw the data onto the meters as it would look on the screen.

I think the best way to display this data is…..because….

DataloggingClass Noise Chart

You will take 6 readings. The readings will record different levels of sound. When you have completed the recording write them on the chart.

Time Temperature

probe A

Temperature probe B

Decide what you will do with your probe for the 2 minutes because you will need to label the graph later.

Record your actions in the grid below.

Now label your graph and interpret the results.

Questions about your temperature experiment.

Which position was the warmest?

Which position was the coolest?

How long did it take for the temperature to change from warmest to coolest?

Why did the temperature change when you rubbed the tip of the probe?

These mats are on/off switches, and are activated by stepping on to them;

one mat starts the timer, the other stops the timer.

Possible activities

How long can I stay in the air when I jump?How fast can I hop, walk, run?

How many jumps can I do in a minute?

Set up your own experiments using the data loggers to answer these questions.

How does physical activity affect your heart rate?

Monitor your heart rate for 5 minutes:•While sitting down quietly.

•After walking slowly,•After running on the spot.

Does eating chocolate have an effect on your heart rate?

What is the effect of different types of music on people’s heart rate?
