Biology
Chick Life Cycle Exploration Set
This educational set consists of 21 eggs that illustrate the development of the chick day by day inside the egg. Each egg can be opened and contains a realistic representation of the embryo’s developmental stage from day 1 to day 20. The last egg contains a small model of the finished chick. The eggs are approximately 7 cm long and come in a tray measuring 38 x 21.6 cm. English activity guide included.

Miscellaneous
Clinometer
This clinometer is a simple protractor made of impact-resistant plastic, equipped with a pistol grip for easy aiming. The instrument is used to measure the slope or height of distant objects such as trees, towers or buildings. Using trigonometric calculations, heights and distances can be calculated from the measured angles.
