Sugar isn’t always bad, but eating too much can cause health problems. When we eat sugar, a hormone called leptin tells our brain to stop eating. However, if we consume too much fructose, a type of sugar, it can cause our brain to ignore leptin. This might lead to overeating and gaining too much weight. Also, extra sugar turns into triglycerides, a kind of fat that can build up in our blood vessels, increasing the risk of heart attacks and strokes. Too much sugar can also harm the collagen and elastin in our skin, causing it to sag and wrinkle. Studies show that women who drink sugary drinks daily have a higher chance of developing diabetes.
Dandruff happens when our scalp sheds skin cells, creating white flakes. A yeast called Malassezia globosa is often blamed for dandruff. This yeast lives on our scalp and feeds on sebum, releasing oleic acid. Some people are sensitive to oleic acid, which can cause inflammation when it gets into the upper layers of their skin. This inflammation makes the skin shed more skin cells, leading to dandruff.
Tardigrades are tiny animals, usually less than 1 millimeter long, known for their toughness. Scientists have found that tardigrades can survive in extreme conditions. When the environment becomes harsh, they enter a state called cryptobiosis, curling into a ball-like shape called a tun. In this state, their metabolism nearly stops, allowing them to survive extreme temperatures, high pressure, and even the vacuum of space. When conditions improve, they return to normal.
Muscle soreness often happens when we start a new exercise routine or do intense physical activity. This soreness is called Delayed Onset Muscle Soreness (DOMS) and usually occurs after eccentric contractions. An eccentric contraction is when a muscle lengthens while still working. For example, when you lower a dumbbell, your biceps lengthen while holding the weight. Similarly, during a squat, your quadriceps lengthen while supporting your body. These contractions create tension in the muscles, causing tiny tears and soreness.
Turmeric is a natural indicator that changes color based on the pH level of a substance. When turmeric powder meets an acid, like lemon juice, it stays yellow. But when it comes into contact with a base, such as a soapy solution, it turns red. This color change shows the presence of a base, which is why a turmeric stain turns red when it touches something basic.
Imagine you are a hormone in the body, like leptin. Create a short skit with your classmates where you demonstrate how leptin works to regulate hunger and what happens when too much fructose is consumed. This will help you understand the impact of sugar on the body.
Conduct a small experiment to learn about dandruff. Use a magnifying glass to examine your scalp or a friend’s (with permission) and identify any flakes. Research and present how Malassezia globosa contributes to dandruff and suggest ways to manage it.
Create a comic strip or a storyboard illustrating the life of a tardigrade. Show how it enters cryptobiosis and survives extreme conditions. This activity will help you visualize and remember the unique survival abilities of tardigrades.
Perform a simple exercise, like squats or bicep curls, and note how your muscles feel over the next few days. Write a short report on your experience with DOMS and explain the role of eccentric contractions in muscle soreness.
Try a hands-on experiment by mixing turmeric with different household substances (like lemon juice and soap) to observe the color change. Record your observations and explain why turmeric acts as a pH indicator.

**Is sugar bad for you?**
Not necessarily! Some people enjoy sweet dreams after consuming sugar. However, consuming a lot of sugar can lead to serious health problems. For instance, a hormone called leptin signals our brain to stop eating. Excess fructose, a type of sugar, can cause leptin resistance, meaning our brain doesn’t respond to leptin properly. This can lead to overeating and obesity. Additionally, excess sugar is converted into triglycerides, a type of fat that can enter the bloodstream and form fatty deposits in blood vessels, increasing the risk of heart attacks and strokes. Furthermore, excess sugar can damage collagen and elastin in our skin, leading to sagging and wrinkles. Studies have shown that women who consume one or more sugary drinks per day are at a higher risk of developing diabetes.
**Topic: Dandruff.**
Why do we get dandruff? Dandruff is a condition where the scalp sheds skin cells in the form of white flakes. A yeast called Malassezia globosa is commonly accepted as a cause of dandruff. This yeast is naturally present on our scalp and feeds on sebum, releasing oleic acid. Some individuals are sensitive to oleic acid, which can cause inflammation when it penetrates the upper layers of their skin. In response to this inflammation, the skin sheds skin cells at an increased rate, leading to the formation of white flakes.
**What is a tardigrade?**
A tardigrade is one of the smallest animals, growing to about 1 millimeter or less in length. It is known for being extremely resilient. Scientists have discovered that tardigrades can survive in very harsh environments. When conditions become inhospitable, tardigrades enter a state called cryptobiosis, curling up into a ball-like structure called a tun. In this state, their metabolic processes nearly stop, allowing them to survive extreme temperatures, high pressure, and even the vacuum of space. When conditions improve, they can return to their normal state.
**Why do our muscles get sore?**
Muscle soreness often occurs when we start a new workout routine or engage in intense physical activity. This soreness is known as Delayed Onset Muscle Soreness (DOMS) and typically happens after eccentric contractions. An eccentric contraction occurs when a muscle lengthens while still contracting. For example, when lowering a dumbbell, the biceps are lengthening while still working to hold the weight. Similarly, during a squat, the quadriceps lengthen while supporting the upper body. These eccentric contractions create tension in the muscles, resulting in tiny tears and subsequent soreness.
**Topic: Acid-Base Indicators.**
Why does a turmeric stain turn red? Turmeric is a natural indicator that changes color based on the pH of a substance. When turmeric powder comes into contact with an acid, such as lemon juice, it remains yellow. However, when it interacts with a base, like a soapy solution, it turns red. This color change indicates the presence of a base, explaining why a turmeric stain turns red when it comes into contact with any basic substance.

Sugar – A sweet substance that provides energy to the body, often found in fruits and other foods. – Eating too much sugar can lead to health problems like obesity and diabetes.
Health – The state of being free from illness or injury and having a well-functioning body and mind. – Regular exercise and a balanced diet are important for maintaining good health.
Leptin – A hormone produced by fat cells that helps to regulate body weight by signaling the brain to reduce appetite. – When leptin levels are high, it tells the brain that the body has enough energy stored as fat.
Dandruff – A common scalp condition that causes flaky skin to appear, often due to dryness or irritation. – Using a special shampoo can help reduce dandruff and keep the scalp healthy.
Yeast – A type of fungus that is used in baking and brewing, and can also live in the human body. – Yeast infections can occur when there is an imbalance in the body’s natural flora.
Inflammation – The body’s response to injury or infection, causing redness, heat, and swelling in the affected area. – Inflammation is a natural part of the healing process, but chronic inflammation can lead to health issues.
Muscles – Tissues in the body that have the ability to contract and produce movement or maintain the position of parts of the body. – Regular exercise helps to strengthen muscles and improve overall fitness.
Soreness – A feeling of pain or discomfort in the muscles, often after exercise or physical activity. – After the long hike, she felt soreness in her legs and needed to rest.
Turmeric – A yellow spice that comes from the turmeric plant, known for its anti-inflammatory properties and health benefits. – Adding turmeric to your diet can help reduce inflammation and improve overall health.
pH – A scale used to measure how acidic or basic a substance is, ranging from 0 to 14. – The pH of blood is slightly basic, around 7.4, which is important for proper bodily functions.
