Children can be taught the fundamentals of scientific knowledge before they start school. Simple experiments can be carried out with simple materials and equipment in home. To improve their curiosity and widen their investigation range, children must be taught theory. It’s a lot of fun to learn while having fun. Children will be more interested in paying attention, and the information learned while playing will be easier to memorize. It will be more memorable to obtain fresh knowledge of scientific theory by participating in a simple scientific practicum.
One of the practical or simple scientific experiments is about the effect of temperature on the process of dissolving molecules.
Tools and materials:
- 3 glasses which are transparent
- Hot/warm water, room temperature water, and enough cold water
- Enough food coloring
Steps to Conduct an Experiment:
- Three empty glasses should be prepared.
- Prepare hot/warm water, room temperature water, and cold water
- Pour each water into three empty glasses
- At (almost) the same time, pour in the food coloring.
- The water in the glass must not be stirred. Keep an eye on the changes that occur.
The reaction, that the liquid food coloring dissolves more quickly in hot water, can be shown in this experiment. The notion of reaction rates is taught in high school chemistry classes. The rate of reaction is substantially affected by temperature changes.
The pace of reaction is related to the rate of temperature increase. The particle motion will accelerate as the temperature rises. The kinetic energy of the articles increases as the particles move, resulting in more particle collisions and a more efficient reaction.
Electric stoves and Bunsen burners are commonly provided in chemistry lab. These two tools are used to heat up the compound. A solution poured into a flask or beaker is commonly heated on an electric stove. The Bunsen burner is used to heat test tubes and is utilized as a heater in qualitative chemical assays.
Children are exposed to the course of reactions in this simple scientific experiment. That there are reactions that go slowly and reactions that run quickly in everyday life. One of the causes of an increase in the response is a rise in temperature. An example of dissolving color in three types of water at different temperatures will help children recall this basic notion.
