Data Sense, Handling and Interpretation:
-
- Almost every scientific investigation or experiment is likely to require one or more of the mathematical skills of classifying, counting, measuring, calculating, estimating, and recording in tables and graphs. Students will, for example, order numbers, including decimals, calculate means and percentages, use negative numbers when taking temperatures, decide whether it is more appropriate to use a line graph or bar chart, and plot, interpret and predict from graphs. They will explore rates of change in cooling curves and distance-time graphs, apply formulae and solve equations, for example, in problems on moments;
- representing data accurately using appropriate graphs, charts and tables, identifying patterns and trends, interpreting effectively and making predictions;
- present and display information collected in an investigated project using a pie chart, line graph, bar chart etc.;
- collect scientific data from a variety of sources to determine relationships between two variables. Use the trends apparent from the graphs and tables to determine trends, e.g. the graph of time versus temperature;
- analyse data from statistic surveys and calculate the percentage of data in a given category;
- representing and interpreting tables, graphs and data from experiments;
- cause and effect;
- tabulating and graphing data;
- reading scales;
- pie charts of food groups;
- bar charts of daily calorie intake;
- calorie counting;

- use first-hand and secondary data to carry out a range of scientific investigations;
- exploregrowth and how to measure it. Explore the range of heights in the class, and compare
to data of expected heights;
- compare data about individuals, produce graphs of variation for particular features and investigate correlations.
In the area of Data Sense, Handling and Interpretation, teachers of science may consider the following when deciding how work in science links with using and applying numeracy in Coláiste Bríde:
-
- What aspects of handling data are developed during science lessons? How are ICT devices used in this work (for example, sensors, spreadsheets, computer graph packages, calculators, graphical calculators)? How does this work enhance students’ mathematical development?
- How does science help to develop students’ understanding of numbers in context, particularly large numbers, fractions and decimals, indices, ratios and proportions, and the relationship between different metric units?
- Does the teaching and interpretation of formulae and graphs support the expectations in numeracy? What use is made of different forms of graphs in science? Have we agreed with numeracy how graphs should be labelled and presented? Does the progression in graphical work in science support its development in numeracy? How is ICT used (graph plotters, graphical calculators) to support this work?
Number Sense and Computation:
- Opportunities for counting and measuring, e.g. how many seeds in a pod?
- performing mental calculations;
- counting, classifying, estimating, ordering numbers;
- calculating means and percentages;
- use strategies, estimation and contextual knowledge to confirm calculations and answers are reasonable;
- timelines (geological);
- using / reading stop watches;
- use number sense and knowledge of scientific facts to determine the accuracy of calculations
within reasonable limits. Given that the average pulse rate is between 60 and 90 beats per minute, students can determine the accuracy of calculations of average pulse rate, and the determination of actual pulse rate, when it is measured as beats per 15 seconds and converted to beats per minute;

- select and use simple and formulae to solve numerical problems;
- use percentages to calculate and solve problems;
- calculate the fat content of commonly eaten foods using a calorie counter or fat – fibre guide;
- use numbers sense, appropriate strategies, computational skills and key information to solve
numeracy problems, e.g. given the formula for speed, calculate the speed when given the start
and finish times and distance travelled;
- read, write, compare and order positive and negative numbers, e.g. use thermometers to
measure temperatures in the environment;
