Summary -
READ AND FIND OUT - (page. no. 32)
1. How did a book become a turning point in Richard Ebright, 's life?
Ans - The book," The Travels of Monarch X" became a turning point in Richard Ebright's life, because, after reading this book, he came to know how monarch butterflies migrate, and it triggered his interest in science, the book was given to him by his mother
2. How did his mother help him?
Ans - His mother helped Ebright in many ways to enhance his interest in scientific understanding such as, taking him on trips, buying telescopes, microscopes, cameras, mounting materials, and other scientific equipment, giving him a book, and helping him in learning things.
READ AND FIND OUT - (page. no. 34)
1. What lesson does Ebright learn when he does not win anything at a science fair?
Ans - At a science fair, he learned that science is not about a display but has to do real experiments when he does not win.
2. What experiments and projects does he then undertake?
Ans - He carried out different projects such as to find a cause of a viral disease that kills monarch caterpillars, the theory behind copying of viceroy butterflies to monarchs, the purpose of the twelve tiny gold spots on a monarch pupa, hormone necessary for the butterfly development, and how cells read their DNA.
3. What are the qualities that go into the making of a scientist?
Ans - The qualities that go into the making of a scientist are first-rate mind, curiosity, will-win, and ability to do the best possible execution.
Think about it -
1. How can one become a scientist, an economist, a historian...? Does it simply involve observing, thinking, and doing experiments?
Ans- To become a scientist, an economist, or a historian, one must have die heart interest and passion for the subject, and as it is a continuous process, it involves many things such as reading books, keen observation, experimentation, applying the learned principles on a ground level reality, gathering pieces of evidence, seeking advice of experts, studying old logics and fundamentals and trying to add something innovative to that, never give-up attitude, strong will, curiosity, so all these qualities collectively make a true legend in the particular field.
Here, I would like to give an example of Thomas Elva Edison, who invented the electric bulb, to succeed, he undertook many experiments to find the perfect metal for the filament of the bulb, and finally, he got the perfect metal, and it was tungsten. Even after many failed attempts, he never gave up and finally discovered the electric bulb. It requires a lot of patience, belief in self, and a tremendous passion to discover something new that never existed.
2. You must have read about cells and DNA in your science books. Discuss Richard Ebright's work in light of what you have studied. If you get an opportunity to work like Richard Ebright on projects and experiments, which field would you like to work on and why?
Ans - DNA is basically a blueprint of the human body, and is the molecule that carries genetic information for the development and functioning of an organism, and helps in carrying out the characteristics from one generation to another.
If I get an opportunity to work like Richard Ebright on projects and experiments, I would like to work in the field of solar energy or solar power, because I do believe that whatever the problems we are facing today like pollution, global warming, different disasters whether natural or a manmade are the results of improper selection of fuel, the fossil fuel we are using today to produce needed energy is the root cause of these problems, and we are ignoring the most prominent source of energy, and that is the energy of sun. The research and data show us that if we properly use solar power for just one hour, our all energy demands will be fulfilled.
But, at the same time, I learned in school from our science teachers that, the problem behind this is the higher cost of solar cells, so we are unable to trap the maximum part of the solar energy, also initial cost of solar power projects is much higher, so I would like to work on minimizing the cost of solar projects so that we can fulfill the energy demand not on the cost of destroying the green environment, so our planet, rivers, the oceans will remain clean, green, pure, and balanced, and thus we can achieve our required goals.
Talk about it -
1. Children everywhere wonder about the world around them. The questions they ask are the beginning of scientific inquiry, Given below are some questions that children in India have asked Professor Yash Pal and Dr Rahul Pal as reported in their book, Discovered Questions (NCERT, 2006)
1. What is DNA fingerprinting? What are its uses?
Ans - DNA fingerprinting is a laboratory technique used to determine the probable identity of a person based on the nucleotide sequences of certain regions of human DNA that are unique to individuals. It is used in criminal investigations, comparing criminal suspects' profiles to DNA evidence to assess the likelihood of their involvement in the crime.
2. How do honeybees identify their own honeycombs?
Ans - It is because the queen's scent, a pheromone that is "hers" is a unique identifying hive marker, and another element is the sense of smell, bees elicit a very good sense of direction, and the ability to transfer information to one another, and every hive is different than another.
3. Why does rain fall in drops?
Ans - Rain always falls in drops and not as a continuous stream. This is mainly due to the surface tension of water caused due to the tendency of water molecules to stick together. Therefore, larger drops split into smaller ones.
2. You also must have wondered about certain things around you. Share these questions with your class, and try and answer them.
Ans -
1. Solar and Lunar Eclipses-
Witnessing a solar or lunar eclipse is a fascinating event where the Earth, Moon, and Sun align in unique ways, creating stunning celestial phenomena.
2. Auroras:
The northern and southern lights, or auroras, are captivating displays of colored lights in the polar regions caused by the interaction of charged particles from the Sun with Earth's magnetic field."
3. Meteor Showers:
Meteor showers occur when the Earth passes through the debris left behind by a comet, resulting in a flurry of shooting stars across the night sky.
4. Bioluminescence:
Certain organisms, such as glow-in-the-dark algae and jellyfish, exhibit bioluminescence, creating enchanting displays in oceans and other environments."
5. Supermoons:
A supermoon occurs when a full moon coincides with its closest approach to Earth, appearing larger and brighter in the night sky.
6. Rainbows:
Rainbows are beautiful optical and meteorological phenomena resulting from the refraction, dispersion, and reflection of sunlight in water droplets."
7. Migratory Patterns:
The migration of animals, such as birds and monarch butterflies, showcases incredible navigational abilities and instincts honed over generations.
8. Volcanic Eruptions:
While potentially dangerous, volcanic eruptions demonstrate the Earth's dynamic and geologic processes, shaping landscapes and influencing ecosystems."
9. Biological Symbiosis:
The intricate relationships between different species, like pollination between flowers and bees or the symbiotic partnerships in coral reefs, highlight the wonders of biological interactions.
10. Gravitational Waves:
The detection of gravitational waves, ripples in spacetime caused by certain cosmic events, represents a groundbreaking achievement in astrophysics"
These events showcase the marvels of the natural world and the ongoing discoveries and advancements in scientific exploration. Observing and understanding these phenomena enriches our appreciation for the wonders of the universe."
