This term the children have been exploring the song Blackbird written and performed by the Beetles. The children have performed the song and have moved on to learn to play the song on glockenspiels.
Science - Human Nutrition
This week we started looking at human nutrition. We first looked at digestion. The children discussed what they already knew about digestion and how the process works. The children identified each stage of digestion. They then went on to practically examine the stages of digestion. They first made a sandwich. Next the cut up the sandwich with a knife to simulate the incisors (teeth) breaking the food into smaller parts. They then mashed the sandwich with a potato masher to mimic the molars (teeth) grinding the food. Then it got messy. Saliva (coloured water) was added to show how it aids in the first steps of digestion. This then traveled into a bag and mixed with stomach acid (lemon juice) to show how food changes in the stomach. The children then transferred the food from the stomach to the intestines (tights). The liquid was then squeezed out of the mixture to simulate its travel through the intestines. At the very final stage the mixture was passed through a hole showing the end of the digestion process.
The children then looked at the first stage of the digestion process. The mouth!. The children used mirrors to observe their own teeth. They then created models of their mouths. The children then labelled the different types of teeth that can be found in their mouths, incisors, canines, premolars and molars.
Science - Sound
This week the children have been learning all about sound. The children discovered that sound is created when something vibrates and sends waves of energy (vibration) into our ears. The vibrations travel through the air or another medium (solid, liquid or gas) to the ear. Through experimentation the children discovered that the stronger the vibrations, the louder the sound and that sounds are fainter the further you get from the sound source. The children also found that sound changes depending on how fast or slow an object vibrates to make sound waves. Pitch is the quality of a sound (high or low) and depends on the speed of the vibrations. Different materials produce different pitches; if an object vibrates quickly we hear a high-pitched sound, and if an object vibrates slowly we hear a low-pitched sound.
