Time is something we all use throughout our lives, although many of us probably don’t think about how it work – we just get on with it!
Us humans divide time up into small chunks, like hours and minutes and seconds; or into bigger chunks, like days, weeks, months and years. And we measure time by looking at clocks or watches or calendars.
Animals and plants and other creatures also measure time but they don’t use clocks – they rely on the amount of light to tell if it’s day or night, and they sense more gradual changes in the seasons.
Time-travel, or the ability to move backwards or forwards through time, is an idea that pops up in stories and films. But could it actually happen?
My daughters love investigating things: from hunting for worms on rainy days or turning over rocks to find beetles, to pouring water between containers, and collecting leaves, flowers, conkers and pine cones! They are great at asking questions about the world around them and trying to think of creative ways to test out answers.
We’ve talked about how to be a scientist but they want to know how science works. What do scientists do when they are doing science? It’s time to find out about something called ‘the scientific method’…
Salt and pepper are seasonings that I sometimes use when I am cooking to make some types of foods taste better. I keep them in special plastic pots with twisty tops that grind the salt or pepper into a fine powder that can be used easily to flavour our food. But my daughters want to know why the salt pot has a lid, when the pepper pot does not?
