Mad Science School Assembly

It was wonderful to welcome Mad Science to Goldfield and end our Science Week with an exciting School Assembly followed by a day filled with amazing Science Workshops.

Our first experiment can be done anywhere at anytime. Let's feel the air around us!

Photograph of Mad Science Assembly

Flap your hands by your ears and not only will you feel the air moving but you will hear it too. It will also cool you down!

Air is hard to see but if we blow up this giant air bag we will be able to see how much air is inside.

Now let's make a science guess or in science language a hypothesis. Who will be able to blow the most air into the giant air bag will it be this young man or young lady?

Photograph of Mad Science Assembly

Our hypothesis is that it will be the young lady as she is bigger, has bigger lungs which should enable her to blow out far stronger and longer breaths. Let's put our hypothesis to the test.

Take 10 breaths and see how much the air bag inflates.

Wow, that's amazing. Well done!

Now let's practise blowing out. Stand up tall take a deep breath in, then blow it out as hard as you can.

Now it's the young mans turn.

Oh, my goodness the air bag is bigger!

Photograph of Mad Science Assembly

Does anyone know why the air bag is bigger?

Photograph of Mad Science Assembly

If you stand a little further away from the opening of the air bag and hold it open as far as you can....more air can get inside!

Photograph of Mad Science Assembly

And just to prove it .....

Photograph of Mad Science Assembly

..... we let our young lady volunteer have another go!

Photograph of Mad Science Assembly

Air can be very strong!

Photograph of Mad Science Assembly

Strong enough to power this rocket!

Photograph of Mad Science Assembly

Can you feel the air rushing out of the nozzle when the pump is pulled out and pushed in again?

Photograph of Mad Science Assembly

Those forces will launch the rocket and send it across the room.

Photograph of Mad Science Assembly

Look carefully, can you see the yellow rocket?

What will happen if I burn this piece of paper?

Photograph of Mad Science Assembly

We should get a flame, some smoke and some ash!

Photograph of Mad Science Assembly

But there is nothing left! Please click on the play buttons below to see this experiment.

 

 

 

The paper used in this experiment was special flash paper. When the paper burns it is so quick and fast all you see is a flash of bright white light even when your eyes are closed or from behind your head! That is also why there is no smoke or ash.

What do you think is inside this cup?

Photograph of Mad Science Assembly

It looks like water but it is not!

Photograph of Mad Science Assembly

Look what happens when I pour this liquid into the cup .... it changes colour!

Photograph of Mad Science Assembly

And when the next liquid is poured in .... it changes back!

 

Animated Thank You Mad Science that was a fantastic assembly!
