Function

Intended for experimental study, a science laboratory, and the performance of experiments on: Elementary school 1. Light is necessary for us to see. The sense of touch of each individual, including. Test your sense of smell, including. Identifying objects by sound. The shape of objects. The vertical position. The arrangement of objects on flat surfaces. Differentiating solid, liquid, and gaseous bodies. The energy of moving air. The identification of some seeds. Is water necessary for seed germination? How to identify different types of soil? The condensation of water vapor in the air. The change of state of water, melting. The erosion of soil caused by the increase in water volume when it freezes. The evaporation of water, the slow transition from liquid to gaseous state. Heat makes ice melting faster. The surface of still water remains horizontal. It produces oxygen through a chemical reaction. Condensation of water, changing from the gaseous state to the liquid state. Erosion of soil caused by moving water. Decantation and filtration, two stages for water purification. Water contained in the soil. The decomposition of fruit due to mold. The lute, a stringed instrument, included. Low and high sounds. Separating objects using a magnet. Using a magnet to separate materials, recycling. Thermal sensation and temperature. Observing the compressibility and elasticity of air. The harmful effects of smoking. Inertia, one of the general properties of matter. The simple pendulum. Force, mechanical deformation, plastic deformation, and elastic deformation. Measuring the weights of different masses. Inflating a balloon, reducing external pressure. Light, transparent, translucent, and opaque media. The composition of colors in a Newton's disk. The phases of the moon. Electrification, principles of electrostatics, static electricity. Force lines and the magnetic field of a magnet, magnetism. The operation and use of a compass. Permanent magnets, temporary magnets, and the electromagnet. Comparing the germinating power of seeds. How does the environment influence the germinating power of seeds. Phototropism in plants. How to classify invertebrates? Do I have color blindness? etc.
