Grade 6 (=pri6) Science Experiment

An experiment done in class

Water ... rising

Can u fit an egg into a bottle?

pH video

Criss Angel walking on water

COOL RIGHT?

How is table salt formed?

Video will be shown on 'compounds' session.

Even a cooler video - the copper coin disappeared (actually reacted completely) with concentrated nitric acid.

Acid-metal reaction

Copper coins in concentrated nitric acid.

Boiling acid

Acidic hot spring

Universal indicator & pH scale

Use of the universal indicator in various alkaline/acidic solutions.

Acid-alkali titration

Acid-base titration. Indicator used is Phenolphthalein which turns from pink (in alkali) to colourless (in acid).

Acid-metal reaction

Hydrochloric acid + zinc give off hydrogen gas. Ignore the words in the video.

Acid-carbonate reaction: carbon dioxide test

This experiment comprises the carbon dioxide test - using limewater (calcium hydroxide).

Acid-carbonate reaction

Reaction between an acid (hydrochloric acid) and carbonate (calcium carbonate). The bubbling (effervescence) is due to the production of carbon dioxide.
