SCIENCEQ1. Unless some force applies a nudge,

A body simply will not budge,But rests if its at rest already,Or else keeps going straight and steady!Well! We all agree with this. Isnt it? This is what is popularly known as Newtons 1st lawof motion. Sir Isaac Newton, the father of mechanics, is one of the most important scientists

who ever lived, changing the standards by which scientists think. His genius in mathematicsand mechanics is exemplified by his creation of calculus to explain observations of the worldaround him. In addition, his laws of motion opened the door to progressive new thinking,enlightening the minds of thousands to the nature of things.This summer vacation try to explore more about this fast moving world by collecting a dataaccording to the given instructions:

(a) Observe the odometer and speedometer of the vehicle in which you are seated duringyour journey to any of the place after every regular interval of time for about half anhour.

(b) Note down the initial reading of the odometer and speedometer.(c) Note down the starting time.(d)Make a table stating time (min), odometer reading (km) and speedometer reading(km/h).

(e) Plot the distance time graph and speed time graph from the data collected.(f) Draw conclusion about the types of motion.(g)State the reason for the type of motion exhibited by your vehicle during the journey.Supporting pictures of your travel/ pictures supporting your conclusion).Use A-4 size interleaved coloured pastel sheets.Use the ruled side for textual content

Q2. Prepare a scrap book/ video/ Power Point Presentation of a biologicalphenomenon:(Examples biogeochemical cycles, working of cell organelles, types of tissues,diversity in plant kingdom, diversity in animal kingdom, vertebrates, acute diseases, chronicdiseases,inflammation, vaccinations- past and present etc.)

Q3. PREPARE A PROJECT ON:Famous Indian Scientist and their contribution in the Field ofDevelopment of Science.You should elaborate upon the following points while pursuing your projecton Indian Scientist;

Scientists Contribution. Global Identity by their Inventions. How does it help to the Nation?A Record File having the following exercises should be maintained:(a) Photographs.(b) Major Contributions.(c) Focus on their inventions & theories.Students should prepare the project as per their roll nos:1.
