Classroom Behaviour and the Weather

Behaviour and the weather

Overview

This project aims to extend students’ ideas and knowledge on correlation using the Weather Observations Website (WOW) website. It focuses on looking at the possible link between the weather and behaviour in schools

The project is more suited for KS4 pupils but a high ability KS3 class could probably cope with its content. It involves pupils drawing scatter graphs or using spreadsheets if they have access to computers.

The ideas here can be taught in a few lessons using these resources or they can be made into a mini project lasting longer.

Teachers can adapt the ideas to suit their needs and tasks can be extended.

For example pupils could design a survey to collect information on behaviour in their own school and gather local weather data using the WOW website. It has possible cross curricula links with maths.

Objectives

To develop knowledge and understanding on correlation between two variables.

To investigate if there is a link between behaviour in schools and the weather.

To use the WOW website to gather data on past weather observations.

To design a survey to collect information on behaviour in your school.

To gain experience in recording data in tables and spreadsheets.

To build on pupils’ ability to draw and interpret graphs.

Introduction

In this task you are going to analyse the weather data for a certain town and establish if there is a correlation between weather and behaviour. For instance, do pupils behave better or worse if it is windy?

The behaviour of the pupils was judged by their teachers over four weeks in the month of March and their behaviour was given a score by their teachers on a 1 to 8 scale.

Behaviour scale

The behaviour scale is determined by the teacher with 1 being excellent behaviour from the class and 8 being behaviour that is seen to be unacceptable from that class for that teacher.

 Behaviour no. Behaviour shown
 1 No interruptions from the class
 2 Very few interruptions to the lesson
 3 When they are completing their own work some pupils get distracted
 4 A few pupils start to distract each other and lose focus for longer periods
 5 Level of noise starts to increase and more off task behaviour is seen
 6 Pupils are distracted from their work and find it difficult to work
 7 Lots of interruptions to the lesson from a range of pupils both in their own work and when listening to the teacher
 8 Constant interruptions to the lesson, unable to work in the lesson

Worksheet exercise

Ask the students to use the worksheet to draw a graph. If time and resources permit they can gather their own data from WOW. Alternatively they can use the data from the completed worksheet.

Worksheet 1

Answers for Teachers

Extracting the weather data from WOW 

 

1. Go to the WOW website address and search for station 3034 or St-Athan.

2. Click on the St-Athan weather station on the map.

3. Click on ‘View Full Observation’.

4. Click on the Graph tab.

5. Click on the ‘Show Filters’ tab and then the ‘Filter Options’ drop down box. Select ‘Air Temperature’ and ‘Wind Speed’, set the date range to the first week of observations (5/3/2012-9/3/2012), then click Update Graph.

5. To obtain the wind speed readings – go to the correct day and estimate the wind speed reading at 12:00. Fill this in the table of results.

The reading on 05/03/2012 at 12:00 is 13mph. So write 13 mph for the wind speed.

6. Repeat this for each day of the week and then reset the date range for the next week. Do this by clicking the ‘Show Filters’ tab and then the ‘Filter Options’ drop down box, then ‘Update graph’.

Measuring Raindrops

How big is a raindrop?

Collect data and analyse mode, mean and median, range, interquartile range and standard deviation

Introduction: There are many words and many descriptions for different types of rain: fine rain, heavy rain, pelting down, mizzling. In fact the BBC news magazine has an article entitled “Fifty words for rain”. But how big is a rain drop? Does the size vary depending upon the time of year or the type of rain?

Aim: To collect data, manipulate data and analyse data to calculate and compare the size of raindrops.

Equipment Required

  • A platform of area of about 0.5m2 with edges.
  • Enough flour to cover the platform to a depth of about 3cm
  • An accurate measuring device, e.g. electronic sliding callipers.

Collecting the data

  • Cover the platform with the flour.
  • Place the platform in the rain for about 90 seconds, long enough for about 200 raindrops to hit the platform.
  • Use your measuring device to measure the diameter of the raindrops and record the data.

Manipulating, analysing, displaying and interpreting the data

There follows a number of suggestions of how the data can be used depending upon the ability of the students.

1. Calculate the mode, mean and median diameter of raindrop. Which is the most appropriate measure to use? Compare results from different groups.

2. Group the data into appropriate groups. Represent the data using histograms. Discuss whether it is appropriate to have all the groups the same size of vary the size of the groups. Compare the results from different groups. Compare data collected at different times of year if possible.

3. Calculate the spread of the data using range, interquartile range and standard deviation.

4. Discuss different methods of displaying the data. Is the data discrete or continuous? Should a bar chart or a histogram be used? This activity is ideal for discussing when a histogram should be used and the reasons for using a histogram.

5. Draw box plots to show the distribution of the data. Compare the spread of different data sets. What does this information tell us?

6. Write a report comparing the size of raindrops.

Extension

It may be appropriate for Advanced level students to explore the log-normal distribution as discussed in the accompanying article A Low Cost Experiment for determining Raindrop size Distribution.

Using Tree Rings for Past Weather and Climate

Using tree rings to teach weather, climate, past climate change, proxy climate records, correlation, photosynthesis, regression, the carbon cycle, isotopes and more

close up of tree rings

On the BBC news: the research from Swansea University that supports these resources.

1) Show the Film

2) Play the Game

Trees can tell stories about past climates. Scientists can decode the pattern of a tree’s growth rings to learn which years were warm or cool, and which were wet or dry. Scientists combine the ring patterns in living trees with wood from trees that lived long ago, such as the wood found in old logs, wooden furniture, buildings like log cabins, and wooden ships, in order to build a longer historical record of climate than the lifespan of a single tree can provide.

You can decode tree ring data to learn about past climates using the simulation above. Line up tree ring patterns to reveal temperatures in the past. The simulation has two versions. The standard version is the best place to start. The custom version for schools in the United Kingdom was created to go along with a specific curriculum. It has a longer timeline and includes information about some historical events.

The process scientists use to build a climate history timeline has an extra step that, for the sake of simplicity, is not represented in this simulation. When scientists decode long climate records from tree ring patterns, they don’t physically line up the tree core samples next to each other. Instead, they make graphs called skeleton plots for each sample. They combine the skeleton plots from many samples to build a climate history timeline.

Data source for this simulation
The tree ring data in this simulation is from oak trees in southern England. The data, from the UK Oak Project, was collected from living trees, logs in bogs, beams and rafters in old buildings, old wooden furniture, and wall paintings in a farmhouse dating back to 1592. One sample came from the windlass – the wooden crank used to raise and lower a castle’s gate – of the Byward Tower in the Tower of London.

Collect tree ring samples, align the samples to create a 300 year record and see what weather and climate events emerge here.

Alternatively, use the simple paper-strip version from UCAR.
