Lava lamp experiment: match water and oil layers

Name: Lava lamp experiment: match water and oil layers
Description: An illustrative setup clip shows one representative open bottle per tablet amount; the real investigation uses three fresh repeats at each amount.

An illustrative setup clip shows one representative open bottle per tablet amount; the real investigation uses three fresh repeats at each amount.

Build nine matched trial bottles. This animation explains what to look for; it does not report a measured classroom result.

OBSERVE

Build nine matched trial bottles

The clip illustrates one bottle for each of three tablet amounts. For measured results, prepare three fresh bottles per amount; water settles beneath oil in every bottle.

INTERPRET

Connect the model to the science

Oil and water form separate layers because they do not mix; denser water settles below the oil. The setup clip is illustrative and does not show repeated trials or measured bubbling results.
