Building Science concepts through real experiences.
During daytime, plants take in carbon dioxide and release oxygen in the process of photosynthesis in the presence of sunlight. However, they even respire simultaneously and hence also take in oxygen and release carbon dioxide. But the production of oxygen is more than the production of carbon dioxide. Hence,…
Air is a matter of substance, and hence it contains weight and other assets like density and pressure. Generally, the air surrounding us or objects does not show any pressure because it surrounds with equal pressure. In this science activity, we will observe that air shows its pressure when the…
Air is a mixture of many gases. The molecules of gases present in air have weak inter-molecular forces of attraction. Due to this reason these molecules lie far apart from each other i.e. there are large vacant spaces present between these molecules. So, these molecules are free to move in any direction.…
