We were lucky enough to host a recent visit from a local dentist and her assistant who came to chat to our children about healthy eating and looking after your teeth.
Our Dragonfly educators took this opportunity to extend on this learning through some interesting science experiments that took place over a couple of days.
On the first day, three hard boiled eggs were soaked in three jars respectively, one with water, one with coke and one with vinegar. Our children made predictions about what would happen to the eggs.
Olivia thought that the egg soaked in coke would change into a different colour, definitely black. Rhys, Seth, Sarah, Temujin, Leo, Brianna, Holly, and Zimo decided on some sort of darker colour however Alina thought it would stay white. Bodhi and Asha both guessed it would grow bigger and Wren was certain it would turn brownish. Anushka thought hard and decided it would turn lighter and Steve was certain the egg would have coke on it.
Rhys and Seth looked at the egg in the jar of vinegar and were certain it would break. Wren and Temujin decided vinegar would make the egg grow stronger. Anushka just knew it would turn a different colour of purple. Sarah and Bodhi were convinced it would crack. Leo was confident it would change to blue and Temujin disagreed and thought it would turn into grey.
It was simply inspiring to listen to them all explore scientific concepts and use their ability to hypothesis, guess, predict, ask questions, consider
concepts and explore cause and effect.
In the next two days, the children observed what happened to the eggs. Our scientists saw that the egg soaked in the water remained the same while the egg soaked in the coke turned darker and darker. The egg soaked in vinegar was a big surprise to everyone and turned gooey and softer.
Our Dragonfly Educators suggested our children clean the eggs with tooth paste and it was a pleasant surprise when they found the ‘stains’ on the eggshell came off.
Our reflective children, through their hypnotising and hands on experimenting, used their findings and announced the importance of brushing your teeth and what happens if you drink too many sugary and acidic drinks.
Great work super scientists, a lesson for us all!
Benefits of science experiments with our inquisitive children:
- Learning to use equipment safely and correctly. Equipment could include magnifying glasses, microscopes, magnets, scales, sieves, ramps and weighted objects. Sometimes this can also include chemicals, such as those used for making volcanoes.
- Drawing and writing to hypothesize results and discoveries.
- Encouraging discussion: Talking about what you see, feel, taste, hear, smell and discover.
- Observing changes: Children have the opportunity to develop their observational skills and identify changes and differences, such as changes in matter; for example, melting ice cubes.
- Reading books to explore scientific concepts and further experiments.
- Predicting: Encouraging children to discuss the possibilities of what will happen in the experiment.
- Asking questions: Science experiments encourage curiosity and many, many questions.
- Experimenting with the sequencing of steps to carry out the experiment.
- Exploring the natural environment.
- Exploring the man-made environment.
- Using our five senses: For example, smelling or touching and tactile discrimination.
- Considering maths concepts: For example, comparing size and weight.
- Problem solving: For example, how will we melt the ice? Will we leave it in the room, cook it in a pan or leave it in the sun?
- Exploring cause and effect through various materials.
- Developing an inquisitive mind.
