Mel Giedroyc starts listening to chapter 1 of 'Dustbin Baby' by Jacqueline Wilson. Plus, Dick and Dom with everyday science in How Dangerous Is Your Garden.
Activity 1. Worm-charming
Yes - “worm-charming”! The soil in your garden is full of worms. They tend to stay underground, but can be brought up to the surface by vibrations. Scientist Lucy Robinson from the Natural History Museum showed us two ways that you can create these vibrations:
Stamping - rapid stamping on the ground with your feet for a few minutes can bring the worms up. And the more the merrier - pull in others to help you stamp if you can. Keep an eye out for the worms as they come up, so that you don’t tread on them!
Fork-twanging - if you’ve got a garden fork handy, push it into the ground, then wiggle it back and forward quickly for a few minutes.
In the programme, Dick and Dom’s teams compete against each other to see who can make more worms appear. Whichever technique you try, you’ll probably have more success on a rainy day.
Activity 2. Have a dig around
Get to know your garden better by digging a hole and examining the soil for yourself. Is it crumbly? Or clay-like? Can you see any worms or other living creatures in it?
Soil is a mixture of ground-down rocks and stones, and organic matter such as fragments of rotten leaves. The worms and other organisms in the soil are constantly recycling the dead leaves and other decomposing matter in the garden - so as Dom said, your soil is actually full of worm-poo! But that’s what keeps the soil full of nutrients, so worms are definitely a gardener’s friend.
Remember to wash your hands when you’ve finished digging in the soil.
Activity 3. Make a grass whistle
Did you know you can make a sound with a blade of grass?
First, find a blade of grass around 10cm long. Position your hands so that your two thumbs are side by side. You’ll see they are squashed together at the base, and also at the knuckle, but in between there’s a slight gap. Take the blade of grass, and reposition your hands so that the blade of grass runs down between your thumbs, and through the gap in the middle. The blade of grass should be side-on as you look through the gap. Now put your mouth to the gap and BLOW! If you’re lucky, you may get something that sounds like a birdcall. (If you don’t, keep practising, and try adjusting the blade of grass, making sure it’s held tight). What’s happening?
The grass whistle works on the same principle as a reed instrument like a clarinet or a saxophone – though you don’t have as much control over the note played! The note is created because as you blow past the blade of grass, it flutters back and forward, vibrating the air. These vibrations travel through the air to our ears where we hear them as sound. The broader the blade of grass, the lower the sound you will produce.
