Watch Science Come Alive
Seeing an experiment performed makes learning even more powerful. Below are demonstrations from our books, where simple materials are transformed into meaningful scientific exploration. These activities show how everyday objects can reveal important scientific principles in action.
Expansion of Air
(From the book: Air and Water)
The Expansion of Air experiment illustrates how air expands when heated. Using a glass bottle and a coin, learners observe how warming the air inside the bottle increases air pressure, causing the coin to move. This simple activity clearly demonstrates that air, though invisible, occupies space and responds to temperature changes. By observing the movement of the coin, learners gain a deeper understanding of air pressure and thermal expansion — concepts often explained theoretically but rarely experienced directly.
Loop Glider
(From the book: Air and Water)
The Loop Glider experiment demonstrates how air resistance, balance, and aerodynamic forces influence motion. By attaching two paper loops to a simple straw, learners create a lightweight glider that travels smoothly through the air when thrown. This activity helps learners observe how air interacts with objects in motion. The size and placement of the loops directly affect stability and flight path, allowing students to experiment with adjustments and see immediate results. Through this simple model, abstract ideas about airflow and balance become visible and easy to understand.
