4. Wear appropriate safety attire when in the laboratory-safety goggles, lab aprons, etc. | 4. Do not use the phone or computer with gloves on your hands. |
2. Study the underlined Predicate in each of the sentences below and note the difference:
2. He become tired, [(verb (become) + complement (tired)]

5. Think and answer in your own words.
Question (a)
What common characteristics did Marie and Pierre share, as a student?
Answer:
When Marie went to Sorbonne the University of Paris she spent her days in poverty. Her friend Pierre was brilliant but a poor scientist. Due to lack of money they began to work in a shabby laboratory. Being students they were brilliant scholars but poverty was an obstacle in their way.
Question (b)
Which of the two scientists was greater than the other? Say why.
Answer:
I think Madame Curie was greater than Pierre Curie because she wanted to study in Paris but the poverty at home did not allow her to continue. But with her own efforts and confidence she could fulfil her childhood dream. Even in that condition she got married to a person who was poor. And even after his death, she did not deter and continued her work and was awarded the Nobel Prize. It shows that she was really a great human being and a scientist.
Question (c)
Why was the gift of a ton of pitchblende, a great stroke of luck to the Curies?
Answer:
Being very expensive the Curies couldn’t buy pitchblende on a large scale but when their admirer, the emperor of Austria gifted them the most precious gift of a ton of pitchblende they could do their experiment on a large scale and find out what they wanted to achieve. So it was a great stroke of luck to the Curies.
Question (d)
Besides the uses of Radium and Polonium mentioned in the text, in what other way do you think, it is used in the field of medicine?
Answer:
Radium is used to produce radon gas which in turn, is used to treat cancer. Radiation given off by radium is sometimes used also to study the composition of metals, plastics and other material.
The alpha rays emitted by Polonium can be used to eliminate static electricity. Polonium is also used in anti-static brushes to eliminate dust on photographic film.
Question (e)
What proves that Marie Curie was a true lover of humanity and not of wealth?
Answer:
Marie Curie could have patented her discovery and earned a lot of money. But she believed in working for Science and whatever she discovered belonged to the people and not to her so in real sense she thought about humanity not money. She was a true lover of humanity and not of wealth.

Solution & Step-by-Step Answer:
Sanjay Sharma, In-charge of Science Committee, New English High School, Akola-444 001. 1 January, 2020.
To, Respected sir, With regard to learning Science content, processes and views of the nature of Science experiments play significant role in Science. As per the new syllabus, new subjects and some experiments are included in revised Science coursebooks. Experiments give immense pleasure of self-learning and observations. The equipment and apparatus that we have been using in our Science laboratory are outdated and rarely of any use. If we bring some new, definitely it will arose interest in learning Science and doing some experiments on our own. Being in-charge of Science Committee, I request you on behalf of all students and teachers to bring following equipment and apparatus in our Science laboratory. You are well aware that due to lack of equipment our Science teachers can’t conduct some experiments in the lab. Hope you will understand our difficulty and buy the listed equipment and apparatus as early as possible so that the subject of Science can be well understood by doing various experiments in the laboratory. Thanking you, Yours obediently, 10.‘There is no short-cut to success’. Expand this maxim with a suitable introduction, body, examples and conclusion. Write it in your notebook in about 20 lines.
Question 1
Maharashtra Board Solution
‘There is no short-cut to success’. Expand this maxim with a suitable introduction, body, examples and conclusion. Write it in your notebook in about 20 lines.
Solution & Step-by-Step Answer:
‘There is no Short-cut to Success.’ It is often said that success requires hardwork and great diligence as well as commitment. This makes success a long-term achievement. Everybody thinks that there are some easier ways to live life, no need to work hard for livelihood but the truth is that easier ways are always the toughest ways. Most of us forget that for reaching success, the road is not strewn with roses. Success is an achievement by constant diligence and most of us lack the essential quality, diligence. The magic of hardwork and perseverance cannot be underestimated.
Most of the time it happens that we start our efforts but soon lose heart half-way and give up our efforts and thus fail to reach the pinnacle of success. If we have the confidence in our efforts, there is nothing that can deter us from achieving. Sitting in front of Television and watching the shopping network channel, fascinating over the new-miracle making abs machine which promises you the six- pack abs only in 5 minutes of daily exercises, you think that product is heaven sent, so you grab your phone book the order and start dreaming about your perfect body. Two months later, that wonder abs machine is at the back of your master closet gathering dust. As you can see, you will have to do the work when reaching a goal and the success that comes with it. You have to understand that you might have to make sacrifices during your journey and you need to put in the hours required in order to get where you want to reach. Those who sit pretty and just complain about the success of others are the ones who do not do much in life. Those who make continuous efforts for a long time in the right direction rarely lose in the struggle of life. So one important password for all of us to follow is that there is no short cut to success. Project: The life and work and inventions of Marie Curie are given in detail in the text.
