Green and Growing: The Life of a Seed
As you know, there is a vast number of different kinds of plants growing all over the world, from snowy slopes to Amazon rain forests to dusty deserts: plant life is everywhere. So how does it all work? Lets start with seeds.
The Life of a Seed
Picture a seed – I am sure you have all seen them. It will have a hard outer shell to protect it. When it has found the right conditions of warmth and moisture, this shell will crack or split as a root pushes its way out to take hold in the soil. Then the plant will start to grow and a shoot will make its way upwards, with the root growing down, to draw moisture from the ground and provide some balance for the plant, keeping it firm in its place.
Just like you and me, plants need food to grow. Their food is very different from ours, of course! Here’s what they do: the leaves draw water up from the roots, through the stem, and they also soak up sunlight and air. These three things combine to make food in the leaves, where it is stored. Now think of an onion. It is formed to store the food for the plant.
Who On Earth Invented … The Pedal Bin?!
Continuing our series on enterprising inventors of everyday things we take for granted, Sally Anne asks …
Who on Earth invented…the Pedal Bin?!
You’re carrying something to the bin, your hands are full and you don’t want to spill it. Thank goodness for the pedal bin! Read on to find out about the inventor who tried to make life easier.
Ergonomics is the science of making equipment which fits and works with the human body. This basically means making things work as easily and as conveniently as possible. Dr Lillian Gilbreth was a keen inventor who believed in finding the easiest way of getting things done. As such, she invented a range of gadgets to make jobs easier, including the pedal bin in the 1920s. Now we have to admit, pedal bins aren’t very exciting, but Lillian’s life definitely was.
Ailsa – Our ContiReporter at Women’s U17 EUROS – Day Two
Tuesday 26th of November
Today was match day! England v Italy.
The match was at Telford Stadium so we had a 50 mile journey from St. Georges Park to get there.
It was a rather cold day to be outside but it wasn’t shown by any of the excited school children that flooded the ground, ready to watch the game. Before the match began outside the stadium, Continental Tyres were running a Conti Fan Zone. A variety of football activities were being run for the energetic children.
I had a go at measuring the speed of my kick. On my first go I fluffed it and didn’t even hit the target (that’s why I play in goal!) but on my second go I managed to get 29mph which was quite good.
I had to do a piece to camera about what went on before the match and interviewed two Birmingham City Ladies who were taking part in the activities.
Me and my cameraman David positioned ourselves by the team dugouts, ready and waiting for kick off. When the game finally kicked off it was a fast, exciting game.
Both teams were equal and no team was particularly dominant. The England captain, defender Leah Williamson was a stand out player as she was clearly comfortable on the ball and lead the team with ease.
At half time it was 0-0. For the second half me and David retreated to the press box, due to the days coldness, where Simon and Dad had been watching the game and famous footballer spotting.
I had to do some reporting to the camera at half time about how I thought the match was going. The second half was just as gripping and as nail-biting as the first. Unfortunately England conceded an untimely goal off a deflection. England continued to battle throughout the second half and continuously tried to win themselves back a goal, they came staggeringly close to scoring again but unluckily when the final whistle blew, Italy won 1-0.
The score didn’t reflect the game, a draw would have connoted the game more suitably. After the game, I got the chance to ask Lois Fidler a question at the after game press conference.
Following the press conference I then got the opportunity to interview the current England Ladies Manager, Brent Hills, who was lovely and chatty, I still can’t believe I got the chance to interview him.
I was also fortunate enough to be able to interview Alex Scott, England international, Dave Sampson, Bristol Academy Ladies Manager and four of the Under 17 girls, Leah Williamson, Keira Walsh, Chloe Kelly and Molly Rouse.
I was overwhelmed by the people I got the chance to talk to about the game. As the day came to a close it was time for us to go back to St. Georges Park after a long, jam-packed, thrilling day.
Winter Wonderings – Are Snowflakes Really All Different?
It’s a common belief that no two snowflakes are the same, and in a way this is true. No snowflake can ever be completely identical to another, because when you get down to the molecular level they will have slightly different kinds of water molecules, different electrons and different traces of other materials such as specks of dust.
However, if we’re talking only about the appearance and shape of a snowflake, then yes it is possible that some will have duplicates. Snow crystals can vary from fairly simple, hexagonal structures to the more complex and delicate shapes that we commonly think of as snowflakes.
The simple flakes have far fewer molecules than their larger cousins and so it’s entirely possible that you could find two that appeared identical when viewed through a microscope. The more complex structures, however, can have more than a hundred different features and each feature can form in a number of different ways. This makes it highly unlikely that you would ever find two large snowflakes that looked the same – but you could have fun trying!
