As a chemistry student; (a) Help the children to understand how the nature of the products suit their work. (b) Explain what would happen to the elder child after using the tablets for a long period of time. (c) Explain to the children why the process of healing was not the same.

Here are the answers for Item 1:

a) As a chemistry student, you can explain that the tablets are designed to deliver a specific amount of medicine to the body in a controlled way.

• Tablets are solid forms containing an active pharmaceutical ingredient (API) and other substances (excipients).
• They are formulated to dissolve and release the API at a specific rate and location in the digestive system (e.g., stomach or small intestine).
• This controlled release ensures the medicine is absorbed effectively into the bloodstream to reach the site of pain and provide relief. The tablet's structure protects the drug until it can work properly.

b) Long-term use of pain relief tablets can lead to several adverse effects on the elder child's health.

• Depending on the type of painkiller, prolonged use can cause damage to the stomach lining, leading to ulcers or bleeding.
• It can also affect the kidneys or liver, potentially causing long-term damage to these organs.
• The body might also develop tolerance, meaning higher doses are needed to achieve the same pain relief, or even dependence.
• Additionally, continuous use might mask a more serious underlying medical condition that requires proper diagnosis and treatment.

c) The process of healing was not the same because the younger child altered the way the tablet was meant to be taken, affecting its effectiveness.

• The elder child took the tablet as intended, allowing the medicine to dissolve and be absorbed correctly.
• The younger child mixed the tablet with hot water, lemon juice (acidic), and ginger extract.
• Hot water can sometimes degrade the active ingredients in the tablet, reducing their potency.
• Lemon juice can react with the tablet's coating or the drug itself, potentially breaking it down prematurely or altering its chemical structure, which affects absorption.
• Ginger extract might also interact with the drug, further reducing its effectiveness or changing how the body processes it.
• These changes meant that less of the active medicine was available for the younger child's body to absorb, leading to less effective pain relief.
