My discoveries
Light is one of the kinds of energy. We see only objects on which light falls and bounces back into our eyes. A shadow is a place where light does not reach. White light consists of seven colours called the spectrum. Objects can both absorb and reflect light. A sound source is very fast vibrations. Sounds are high, low, loud and quiet. Timbre is a sound’s “colour”: by it we recognise whose or what sound it is. This year we learned a lot about ourselves, our surroundings, nature, Earth and space, substances, energy, light and sound.
Final “Exhibition of discoveries”: each child picks the experiment they liked best this year (bean growth, shadows, rainbow, sound vibration, static electricity) and shows it to the class with a drawing or small model, explaining in 3 sentences: “I did ... I saw ... Conclusion: ...”. Safety: demonstrate only safe experiments.
