Dr Puddledrip
Dragon Snot
Dr Puddledrip has returned from a dangerous expedition with a tiny sample of genuine Dragon Snot. It isn't sticky like glue slime. Instead, it forms long, gooey strands that wobble, drip and hold together like a giant dragon sneeze!
Can you discover the secret behind this strange edible goo and make your own batch of Dragon Snot?

Have you ever...
watched jelly set in the fridge?
mixed jelly crystals into hot water?
seen seaweed washed up on the beach?
wondered why some foods are runny while others are wobbly?
Some materials stay as liquids.
Others can suddenly change into soft gels.
Today you'll investigate one of the strangest materials of all...
Dragon Snot.
Before anyone explained how Dragon Snot formed...
You investigated it yourself.
You made predictions.
You compared two mysterious dragon potions.
You watched carefully as the goo began to form.
You observed where it appeared first.
With every observation, you collected another clue about what was really happening.
Now it's time to put those clues together and solve the mystery.
Your investigation revealed something surprising.
Neither dragon potion created the Dragon Snot on its own.
The transformation only happened when the two potions touched each other.
So why did this happen?
One of the dragon potions contained long molecules called polymers. These long chains floated freely through the liquid.
When the polymers touched the calcium solution, tiny calcium ions acted like little bridges, joining the polymer chains together.
As more and more connections formed, the liquid changed into a soft gel that held together as one long gooey strand.
That's why you could lift the Dragon Snot out of the bowl instead of it simply mixing into the water.
Scientists call these tiny connections cross-links.

Think Like a Scientist
Scientists don't just do ONE experiment; they change one part of the experiment (independent variable) and then see how it affects another part of the experiment
(dependent variable)
Change ONE variable and test again.
What happens if the Dragon Slime stays in the calcium solution for longer?
Can you make thicker or thinner Dragon Slime worms?
Which shape stays together the best?

TOMORROW?
Running the experiment is easy; however, teaching it well is another challenge.
Teachers often ask:
How do I adapt this for Stages 1,2 or 3?
What misconceptions will they have?
What syllabus outcomes does it cover?
What do I do with fast finishers?
How do I structure this for a full class?
What do I say when they ask WHY?
