SERIES Endless Wonders


ふしぎエンドレス [NHK]

|Length : 10min. x6 |Year : 2020

Endless Wonders is a science program for elementary schoolers. The “Wonder Monsters” featured in the program will take children on a journey to discover and challenge the wonders that can be found around them, through exciting footages and everyday references.
These episodes are mainly aimed for 5th graders. In each episode, the Wonder Monsters present a particular everyday “wonder.” The program guides children to make predictions about the factors that are key in unraveling that wonder, and gets them thinking about how they can check their predictions through experiments. What are the conditions? How do you check if a prediction is correct? Wonder Monsters grow by eating what the children discover!
The discussions and sharing of ideas between the elementary schoolchildren who appear, serve as hints for the viewer to start thinking science too.

(5th Grade How Do You Make an Electromagnet Stronger?)
When an electric current flows through an electromagnet with a wire wrapped around its iron core, it becomes a magnet. Now, how can we make it stronger? Do we make the iron core bigger? Do we change how we wrap the wire? Do we use a thicker wire? Let’s make predictions and think about how we will conduct the experiments.

(5th Grade Let's Improve the Electromagnet Experiment)
In the previous episode, the children thought about how they can make an electromagnet stronger and conducted experiments. Two groups predicted that “the more times an electromagnet is wrapped with wire, the stronger it gets” and did the same experiment using the exact same materials. However, the two groups saw different results. Why is this? When they do the experiment one more time, this time...

(5th Grade How to Do Researches)
A plastic bottle rocket that flies with the help of water and air. How can we make it fly farther? Do we pump in lots of air? Do we fill it with lots of water? Do we increase the angle of the launch pad? In order to check whether a prediction is correct, we need to experiment. But then, what are the important points we need to be careful about when doing the experiments? When checking how the amount of water affects the power of the rocket, what do we do with the amount of air?

(6th Grade How Does Water Reach the Leaves?)
Does water go up the stem like it does in a straw? Does it soak in like it does in a sponge? To check this, we cut the stem and observe very closely. What can we tell from what we see? We take it a step further and add color to the water to see where the water is passing. What do the schoolchildren say?

(6th Grade Why Does the Moon Change Shape?)
Are there multiple moons? Is it emitting light, or is it changing where it’s emitting light? Is light being shed on it from elsewhere? A crescent moon, a half moon, a full moon... We’ll take a good look at all kinds of moons through a telescope, observe the details, and narrow down the possibilities. What’s the conclusion?

(6th Grade How Does the Moon Change Shape?)
By looking at how the moon changes its shape and location in the sky every day, we predict that the positional relationship the moon has with the sun and earth has something to do with it all. We prepare a light that represents the sun and a ball that represents the moon to visualize the hypothesis. What’s the conclusion that we reach from the experiment?
