    CLASS IX

    WEEK 1

    ISA Activity 3

    Harvest festivals are celebrated worldwide at different times of the year. It is a time when

    farmers thank Mother Nature and celebrate the joy of a successful harvest.

    As part of ISA project, students of class IX are required to carry out a detailed study on the

    following harvest festivals:

    Class/Section Country Harvest Festival

    IX A and IX B Italy Olivagando

    IX C and IX D Indonesia Rice harvest festival

    IX E and IX F Ghana Yam festival/Homowo

    IX G and IX H India Baisakhi

    (a) Students should search and collect information pertaining to the specific harvest

    festival on given topics:

    • History related to the specified harvest festival

    • Culture, traditions, rites and costumes of people involved.

    • Significance of harvest celebrations with respect to joy of a bountiful harvest and

    vision for a hunger free world.

    • Cuisines/recipes prepared with the harvested crop.

    Collected information should be presented in the form of posters (A3 sheets), articles

    (Hindi and English - on A4 sheets) and brochures.

    (b) Make informative and colorful pamphlets highlighting nutritional composition and

    health benefits of the crop involved in specified harvest festival.

    (c) Self composed poems (Hindi and English) depicting gratitude and respect towards

    farmers, production and harvest celebrations.

    All material needs to be kept safely for display in school on ‘World Food Day’.

  • 2. A great news for you! The school is initiating a Book Club for book lovers, crawling

    readers as well as those who wants to fall in love with books this summer ....

    We will hold some exciting activities, watch parties and events based on your reading. You

    are supposed to read a biography or an autobiography to participate. So, get set go! Choose a

    book and let your class teacher register your book's name latest by Monday...

    Wish you all a very happy reading

    Calculate (i) Speed

    (ii) Velocity of car for this journey.

    position. Calculate

  • i) the total distance travelled by the body ii) the displacement of the body.

    Q6 Train A travells a distance of 120 km in 3 hours whereas another train B travells a

    distance of 180 Km in 4 hours. Which train travels faster.

    Q 7 Draw distance time graph for uniform and non uniform motion.

    Q8 A scooter moving at a speed of 10m/s is stopped by applying brakes which produce a

    uniform

    acceleration of –0.5 ms-2. How much distance will be covered by the scooter before it

    stops?

    Q9 A moving train is brought to rest within 20 sec by applying brakes. Find the initial velocity,

    if the

    retardation due to brakes is 2 m/s2.

    Q10 A particle is moving in a circle of radius 1m. Draw a diagram to show the following

    positions of the

    particle

    a) 1m. from the center,300 North-East

    b) 1m. from the center, 300 West-North

    c) 1m. from the center towards South

    Q11 How many different types of velocity-time (speed-time) graphs are possible for a

    straight-line motion?

    Q12 Explain using distance – time graphs a)When the body is at rest b)When the body is

    moving with a

    uniform speed c)When the body is moving with a non-uniform speed .

    Q13An object starts from rest and is uniformly accelerated so that its speed is 60 m/s after

    20s. If it travels

    with this speed for 40 s and is then brought to rest by a uniform retardation in 30 s. Sketch

    the

    velocity-time graph and calculate the acceleration, the retardation and the total distance

    travelled.
