Activity for the 1st cycle

Educational aim


This LES serves as a pretext to:

-the exploration of the conservation of matter (liquid quantities and volume)

-the development of good work methods;

-initiate the concept of solubility;

-problem resolution (economic aspect of consumption).

Activity 3


Activity 3


A preparation guide has been supplied for all the activities. We tried to establish a materials list using every day items.

Mixtures – Theoretical capsule

  • What is a mixture? (4 definitions)

  • What are the two types of mixtures?



We can not distinguish the different substances present at the start.

We can distinguish the different substances that have been mixed (not always to the naked eye).

Mixtures – Theoretical capsule

  • What is dissolution?

  • Difference between soluble and non soluble

  • Collective demonstration to « live » dissolution

  • Experiments by the students

Mixtures – Student observations

  • On top, there is water, at the bottom, the sand.

  • The water has changed colours. There are grains (pepper).

  • The grains (Epsom salts) have disappeared.

Mixtures – Student observations

  • The grains of sand stay at the bottom of the water and it’s transparent.

  • I put the water in after some sand. I mixed it and the water was kind of mixed with dust and the sand had not disappeared.

  • The water looks yellowish. The water level is higher. (brown sugar)

It may be difficult to manage the activity alone. The teacher would redo the activity with a colleague.
