Compost heaps

People are trying harder to find ways of reusing their rubbish as they are concerned about manmade climate change and use of the world’s resources. The majority of us send our glass, paper and plastic to be recycled – we even reuse ice-cream tubs and glass bottles as containers around the home. But what about leftover food that we can’t eat? Is there a use for that?

Many people throw their scrap food onto a compost heap in the garden – be it apple cores, potato peeling or burnt toast! Compost heaps are a great way of reducing the rubbish a household chucks out while improving your garden at the same time.

You can watch this process happen as the food scraps appear to fall apart, turn brown and most importantly get hotter. In fact, even a small compost heap or food bin can get very hot – sometimes around 40-60 degrees Celsius. If you hold your hand over a compost heap, you can feel the temperature. This increase in temperature happens as the bacteria break down the old scraps and they create carbon dioxide and heat. This isn’t so different to us humans when we’re exercising!

When it gets hot, microorganisms take over. Insects, slugs and worms also join in, eating the food and excreting the finished compost.

After a few months, once the compost has cooled and all the food has broken down, it should be ready to put into the soil. This introduces nutrients into the earth which are much needed by plants. The microscopic organisms also help to bring air into the soil. This makes for a very healthy crop of veg – whose peelings and leaves can be thrown into the heap next year!

Rock pooling

We’ve just got back from a holiday in Polzeath, Cornwall, where we had the pleasure of revisiting an old childhood pastime – rock pooling!

Rock pools are truly fascinating finds. They exist in the intertidal zone which means they’re above the sea when the tide’s in and below when the tide’s out. This unique position means that they are natural aquariums which change every day.

We spotted crabs, mussels and hundreds of limpets in the ones we looked at because they were quite shallow. Although rock pools look very picturesque, they are tough places to survive in. Creatures and plants have to cope with frequent changes in temperature, levels of salt and levels of oxygen – affecting how they eat and breathe. This means there are many animals who can’t survive these conditions.

The rock pools closer to the sea spend more time underwater and are therefore easier to live in for more vulnerable creatures. This means that the closer you get to the sea, the more diverse the animals and plants. Depending on where you are, you might find sea urchins, sea cucumbers, snails and whelks!

Next time you’re down at the beach, take a look at the rock pools near you and see what exciting creatures you find!
