Writing down what you find

Why write it down
Test five materials and try to remember which soaked up the most water. By the third one, the first result gets fuzzy. A written record does not fade. It stays exactly the same, whether you check it today or next week.
A simple table
A table has rows and columns. One column names the material. Another column holds the result. Write one row per material tested. A table lets you compare every result at a glance, instead of searching back through your memory. This is a real skill.
Charts show a pattern fast
A bar chart turns numbers into height. The tallest bar is the biggest result. You can see the winner at a glance, without reading a single number. Charts do not replace a table. They make a table easier to understand quickly.
Recording a stretch test
Test how far five materials stretch before they tear. Write each one in a table: material name in one column, stretch in centimetres in the next. Rubber stretches 8 cm. Fabric stretches 3 cm. Paper stretches 1 cm and tears. Draw a bar for each: rubber's bar is by far the tallest. Now anyone can see the winner without watching the test themselves.
Presenting to someone else
A good record answers questions without you standing there to explain. Label every column. Give the chart a title. Say what the units are, like centimetres or seconds. Anyone picking up your table later should understand it on its own.
