use a smart switch to turn off a lithium battery charger
I know that I ought not leave things powered on. Knowing that is easier than remembering that an e-bike or drone or laptop battery is still connected. Below I show how to turn on...
This section is about examining the data that sensors collect from experiments. Understanding the data that sensors provide is surely the reason for bothering to collect it! You can download csv files for all the graphs here to import into Excel or other software. Do use the topics/ keywords to find what you need.

How data handling in science topics can be helped by using an IT tool called a spreadsheet program. Explained, with examples (from ‘IT in primary science’ by Roger Frost).
A ‘branching database is a must-try activity for sorting items and classifying animals.
About databases and how different types of graph are useful
When it is icy they put salt onto the roads to melt the ice. What the salt does is to depress, or reduce, the freezing point of water. The result is that the ice...

If you were a chemical manufacturer you would certainly be interested in finding ways to increase the rate of production. One way is to do the reaction at a higher temperature, and in this...
Datasets (files) like the one below are useful in science. There is data to analyse by drawing graphs. The file below is in a ‘CSV’ format. Open it in your spreadsheet or Datalogging Insight program...
Sometimes you need to graph several variables one after the other – for example, in this weather database, we plotted the daily maximum temperature against time. For clarity, we plotted just 10 days.Next we...

Is mown grass in the compost heap really dead? When you cut the grass you remove its source of vital materials and the cut leaf ‘dies’. But when you feel a pile of cut...
Plaster of Paris is white powder you mix with water and pour into a mould. You can make models with it while hospitals use it on broken limbs. When you mix it with water...
We scientists do the strangest of things. We wanted to see the temperature changes when you freeze and thaw things. So we took a ‘bun’ (a bread roll), placed temperature sensors in and around...
A cart rolling down a hill certainly has energy which in turn affects its speed. But how does this speed change when you start the car off from a different point on the hill....
We used a turn (or position) sensor connected to the computer and recorded the swings of a pendulum made of a metal rod and a weight. We tried again this time connecting the sensor...
You would think that when you heat up ice that it gets warmer bit by bit. And maybe that the more you heat it the hotter it gets. Well it’s not like that. We...
I expect that when something cools, it will get cooler in a plodding kind of way. That’s true, but when something changes state, the cooling is not so steady.The graph below shows how liquid...
We need to keep our homes warm in cold weather. We also need to do this as economically as possible. There are several ways to insulate your home and keep the heat in, and...
What time does it get light in the morning? When does it get dark? Is the central heating working? I just had to know, so I took my data logging equipment and started to...
The dilemma is this: the telephone range as I was making tea. Should I add the milk now or 5 minutes later, after I took the call? One way of answering this is to...
An infrared remote control unit sends messages, using infrared ‘light’ to recorders and televisions. Point a remote controller at a light sensor and it may be able to pick up the signal. This likely works...
The label on my milk bottle tells me how long the milk will ‘last’ at different temperatures. What do they measure to make this assessment? Is it the pH? I summoned patience, collected a glass...

Scientists need to measure and communicate, to handle information and model ideas. In essence, they need to process information. Young scientists have similar needs. When they write, draw graphs, do maths and make measurements,...
