Dairy is a topic that people often disagree about. Some people think it’s great because it has lots of nutrients. For example, a cup of whole milk is packed with important things like calcium, which helps keep our bones strong, and potassium, which helps control our blood pressure. Fermented dairy products, like yogurt, have probiotics that are good for our stomachs. Dairy from cows that eat grass has more omega-3 fatty acids, which are good for our heart and brain.
However, not everyone thinks dairy is good. Some people can’t digest lactose, the natural sugar in milk, which makes them feel sick. Also, humans are the only species that drink milk as adults, especially milk from other animals, which some people find strange.
Blood rain sounds spooky, but it’s just rain that looks red. This can happen for different reasons. In the Sahara Desert, storms can blow brown dust and sand into the clouds, mixing with rain and making it look red. In Kerala, India, tiny red algae spores called Trentepohlia annulata can mix with rainwater, causing the same effect. In Zamora, Spain, another type of algae called Haematococcus pluvialis can get stressed and release a red pigment called astaxanthin, turning the rain red.
When we sleep, we often dream during a stage called rapid eye movement (REM) sleep. Scientists have found that the brain activity of a rat running for cheese is similar to its brain activity during REM sleep. This suggests that rats might dream about their daily adventures. Similarly, a bird’s brain activity while singing is like its activity during REM sleep, hinting that birds might dream about singing.
Spiders are amazing builders! They use special organs called spinnerets to spin silk threads and make webs. First, a spider connects two points, like branches, with silk to form a bridge. Then, it releases a loose thread and adds a new thread from the center, forming a Y shape. The spider connects these points to create a frame and lays radial threads until the web is strong. Finally, it spins in a spiral from the center to finish the web.
Explore the importance of calcium by conducting a simple experiment. Gather some chicken bones and soak them in vinegar for a few days. Observe how the bones become rubbery and bendable. This activity will help you understand how calcium strengthens bones and why it’s important in your diet.
Learn about probiotics by making your own yogurt at home. Use milk and a yogurt starter culture to create a batch of yogurt. Observe the fermentation process and discuss how probiotics benefit your digestive system.
Experience what it’s like to have lactose intolerance by simulating the digestion process. Use lactase enzyme tablets to break down lactose in milk and compare it to untreated milk. Discuss how some people lack this enzyme and how it affects their ability to digest dairy.
Research the benefits of omega-3 fatty acids and create a poster presentation. Include information on how these nutrients support heart and brain health, and list foods that are rich in omega-3s, such as grass-fed dairy products.
Participate in a class debate about the pros and cons of consuming dairy. Prepare arguments for both sides, considering nutritional benefits and potential drawbacks. This will help you develop critical thinking skills and understand different perspectives on dairy consumption.

**It’s AumSum Time. Is dairy good or bad?**
Dairy has become a controversial subject these days. Some argue that it is beneficial due to its high nutritional value. For instance, a single cup of whole milk contains a variety of nutrients that our body needs, such as calcium for strong bones and potassium for regulating blood pressure. Additionally, fermented dairy products contain probiotics, which can improve gut health. Dairy from grass-fed cows is also noted to have higher levels of omega-3 fatty acids, which are advantageous for heart and brain health.
On the other hand, some people believe dairy is not good for everyone, particularly because many individuals are lactose intolerant. Lactose is a natural sugar found in milk products. Furthermore, since humans are the only species that consumes milk in adulthood, especially from other animals, some consider this practice to be unnatural.
**Blood Rain**
Blood rain refers to rain that appears red in color. There are various reasons for this phenomenon. In the Sahara Desert, brownish dust and sand carried by storms can mix with water droplets in clouds, resulting in a reddish hue. In Kerala, red spores of algae known as Trentepohlia annulata can be carried by the wind and mix with rainwater, causing blood rain. Similarly, in Zamora, the Haematococcus pluvialis algae can become stressed and produce a red pigment called astaxanthin, leading to the same effect.
**Dreaming**
Humans experience dreams during the rapid eye movement (REM) stage of sleep. Research has shown that the brain activity of a rat running for cheese is similar to its brain activity during REM sleep. Additionally, a singing bird’s brain activity while singing also resembles its activity during REM sleep, suggesting that animals may dream about their daily experiences.
**Spider Web Construction**
Spiders create their webs using specialized organs called spinnerets, which spin silk threads. The process begins with the spider connecting two points, such as branches, with silk to form a bridge. It then releases a loose thread and adds a new thread from the center, forming a Y shape. The spider joins these points to create a frame and lays radial threads until the web is strong enough. Finally, it spins spirally from the center to complete the web.
