A Petri dish apparatus is a common laboratory tool used for culturing and observing microorganisms. It consists of a shallow, cylindrical dish made of glass or clear plastic, typically with a diameter of 90-100 mm. The dish has a flat bottom and a removable lid that provides a sterile environment for the growth of bacteria, fungi, or other small organisms. The lid helps prevent contamination from the surrounding environment while allowing gas exchange. Petri dishes are filled with a solid or liquid growth medium, providing nutrients for the microorganisms to grow and form visible colonies. These dishes are widely used in microbiology, clinical laboratories, and research settings to study microbial growth, conduct experiments, and perform various tests, such as antibiotic susceptibility testing or environmental sampling.

For many learners high school is not enough to prepare them for what they are to face at first year university. They find themselves completely overwhelmed and intimidated by what is expected of them to be able to do in a laboratory.
Unfortunately many learners who want to pursue science subjects go through this dilemma, few as they are because fact is SA is not producing enough learners who will become engineers, doctors, science researchers, let alone science innovators.
To address this, we developed a chemistry kits with 52 experiments for use by learners at home. This gives them an opportunity to gain hand-on exposure and engagement, confidence and understanding they need to study sciences further.
The kit comes with a manual explaining how science is experienced in daily life and therefore brings awareness of the application and usefulness of science, helping the learner relate to what they learn at school.
Some schools do have kits where only the teacher demonstrates the experiments and this is great, but you don’t master driving by watching the driving instructor, you must get in the driver’s seat yourself.
