Data for answers

I can identify the data needed to answer questions.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. To answer a question effectively, it’s important to first identify what kind of data is needed.
  2. Good questions for data logging are ones that involve change over time or measurable patterns.
  3. Effective data collection requires planning.
  4. You should consider what sensor to use, how often will data be recorded and where will the logger be placed.

Keywords

  • Data logger - a device that records data from the physical environment

  • Collection - the act of gathering something e.g. data

Common misconception

If you gather data for a minute or two to check that the data collected looks ok, your experiment will be successful.

There might be other factors that affect your experiment, which are out of your control. For example, someone could unplug your data logger, the batteries might run out or the data may be corrupt due to an issue with the hardware or software.

Ask pupils to consider what data may have impacted their lives. Being able to understand how technology impacts our lives is an important concept for developing an understanding of the societial consequences of the use of technology.
Teacher tip

Equipment

This lesson is designed around the use of a TTS data logger. If you don’t have access to data loggers, a lot of the activities can be completed using tablet computers and apps.
