I’m Ken Kuwako, your Science Trainer. Every day is an experiment.<\/b><\/span><\/p>\n

Imagine for a moment: what would happen if all the “big, scary bears” suddenly vanished from the forest? Would it turn into a peaceful, lush paradise for everyone else? Surprisingly, the answer is a resounding “no.” Nature is woven together by a complex web of invisible threads. If just one species grows too numerous or declines too sharply, the entire world can transform in an instant.<\/p>\n

Today, I want to introduce you to a digital laboratory where you can manipulate this mysterious “Ecosystem Balance”<\/b> with your own hands. Let\u2019s dive into the surprising drama hidden behind the “food chains” and “food webs” you might remember from middle school science through the power of simulation!<\/p>\n

Bringing Life\u2019s Connections to Life: Digital Food Chains<\/h3>\n

The balance of an ecosystem is incredibly complex and fascinating. However, we can\u2019t exactly run an experiment in a real forest by saying, “Let\u2019s see what happens if we add 100 bears today!” That\u2019s where simulation tools<\/b> on your PC or tablet come in handy. I\u2019ve found two particularly interesting sites for this.<\/p>\n

First, let’s look at a simulation created on Scratch<\/b>, the popular coding platform.<\/p>\n

In this simulation on the Scratch website<\/a>, three players enter the stage: “grass,” “rabbits,” and “bears.” What makes this tool so great is that you can freely change the starting values (parameters) for each.<\/p>\n

Created by satoko1010<\/a>, this tool lets you experiment with extreme scenarios. For instance, let\u2019s try starting with an overwhelming number of “bears.”<\/p>\n
