Metal Reactions Science Trek

Chemistry, Chemical Reactions, Earth Resources and Metals, Primary Chemistry, Age 11-14

Explore strange new worlds as you explain about acids, metals and reactivity. This can be used as a fun summary for lower ability students to describe an astronaught's journey to an alien world made of acid oceans, metallic rocks and strange sea creatures. Get students to use their knowledge of metals to help him collect samples and get back home! Newly updated version at the bottom!


Science Trek: Reactions of metals
Mission Aim:
To know how acids react with metals and metal carbonates.
To know how metals can react together to give off energy.
TASK 1: How acidic?
Your universal indicator computer has tested a sample of the seawater. Write down how acidic you think it is.
COLOUR = RED PH NUMBER = _____
ACIDITY = STRONG/WEAK/NEUTRAL
TASK 2: Spot the reactions
Your computer has jumbled up the instructions for spotting chemical reactions. Write them out correctly.
erapmtueret sire ____________ ______
sublbeb fo sag ____________ ____ _____
melsl _________
ooclur nhaceg ____________ ________
mealf ____________
TASK 3: Ready to dive.
Acid can be corrosive to some metals. Use the data below to decide which metal would be best to make your aquasuit out of.
