Oh, hello, Wowsers! It's me, Guy Ross!

And I'm Mindyth! Welcome to Day 4 of our We Wow Tinkering Challenge!

Now, if you're just joining us for the first time and you have no idea what we're talking about,

just hit pause and go back to Day 1 to catch up. We'll be right here when you're ready!

And if you are caught up, let's take a walk down memory lane, shall we?

On Day 1, we listened to our Wow in the World episode Sunbrella for the Planet.

We learned that some scientists are trying to solve the problem of climate change

by reflecting and deflecting some of the Sun's powerful rays.

We chotted down ideas and came up with a question to wonder about.

Our big wonder was, can we change the temperature and prevent our ice cubes from melting?

On Day 2, we gathered up materials and made a plan to experiment using the Sun's rays

to slow down and speed up the melting of ice cubes.

And yesterday, on Day 3, we designed and tested our experiment.

We used foil hats to reflect the Sun's rays away from one ice cube.

Direct the Sun's rays at another ice cube.

And then we left one ice cube alone for our control.

Remember, a control in an experiment is something that stays the same no matter what,

and it gives you something to compare your results to.

We also measured how long it took each ice cube to melt in each of the three scenarios.

So, Walsers, that's our experiment.
