The Drop Detective
Can you make two water samples match before you test anything?
You will try: Label, measure and keep two samples consistent.
CHEMISTRY DISCOVERY
Investigate reactions, materials, pH, motion and evidence through guided hands-on science.
YOUR MISSION PATH
Follow the main path in order. Optional challenges are separate and are not required for your certificate.
Can you make two water samples match before you test anything?
You will try: Label, measure and keep two samples consistent.
Make an open fizzing volcano, then collect evidence that a gas appeared.
You will try: Describe gas evidence without chasing a bigger eruption.
Use tiny drops to make a colour-changing signal; the mark appears as it is made, rather than becoming invisible ink.
You will try: Use a small indicator mark to detect acidity.
Two clear liquids look alike. Can your test strips identify the hidden base?
You will try: Identify known acid, water and base samples from evidence.
Can you turn invisible chemical differences into an ordered rainbow of evidence?
You will try: Read a coarse chart and compare sample colours.
If you add only water, does the acid disappear—or does it spread out?
You will try: Keep transfers equal and recognise indicator limits.
Can you move an acidic sample toward balance without racing past the neutral region?
You will try: Add controlled drops and follow a changing colour range.
How many drops can balance in one tiny dome before the surface gives way?
You will try: Compare drop counts with and without soap.
Can one tiny touch of soap make a whole field of glitter rush away?
You will try: Use a tiny soap touch to explore a surface effect.
Can water climb up and cross a bridge made from soft tissue?
You will try: Compare wet fronts without promising a particular winner.
Can one simple filter sort a messy mixture into different parts?
You will try: Separate particles while distinguishing filtration from purification.
Choose one question and show another scientist how to repeat your test.
You will try: Design and repeat one safe comparison using earlier methods.
Water can keep moving after your hand stops. Can glitter reveal the hidden flow?
You will try: Extend a main-path idea without making the course longer.
Soap touches water every day. What chemical clue will its solution reveal?
You will try: Extend a main-path idea without making the course longer.
Does stirring change the substance, or only how quickly it disappears into the water?
You will try: Extend a main-path idea without making the course longer.
Does three times the soap create three times the foam?
You will try: Extend a main-path idea without making the course longer.
Can an invisible electric charge make tiny tissue pieces jump without touching them?
You will try: Extend a main-path idea without making the course longer.
