Product Description

This model investigates the water cycle, acid rain, pollution, evaporation and condensation, fresh water from salt water and how materials change. It is simple to set up and operate.

Choose whether to fill the ocean with fresh water, salt water, diluted vinegar or any other safe "pollutant".

Load the cloud with ice and switch on a lamp. The water cycle will begin and rain will fall over the hills and run into the rivers and lake before flowing into the sea. The rain is not melted ice, which is self-contained. The Rainmaker lid remains clear enabling the water cycle to be observed.

The instructions provide full details for quickly and easily making safe organic indicators. Raindrops, rivers, lake and sea can then be tested to determine whether they are neutral, acid or alkaline.

Experiments can be conducted using food colouring or brown sugar as "pollutants". Investigate how we can help nature and protect the environment.

Full teacher’s notes, with experiments and instructions are included.

Lamp not supplied.
