Holiday Homework Science focuses on key scientific concepts such as the construction of a motor/generator model and the exploration of elemental groups like Alkali Metals and Halogens. Students will engage in activities that include sketch-noting the modifications of bone structures for various functions and creating a digital or physical museum showcasing the ‘Great Connection.’ This assignment is designed for students to deepen their understanding of biology and chemistry through hands-on projects and research. Parents are encouraged to support their children in completing these tasks during the vacation period.

Key Points

  • Students create a model of a motor/generator as part of their science homework
  • The assignment includes a travelogue on Alkali Metals and Halogens
  • Sketch-noting activity focuses on the evolution of bone structures for different functions
  • Parents are urged to assist in completing holiday science homework

Holiday H.W SCIENCE X-
1)Prepare a model of -Motor/Generator
2)create a "Digital or Physical Museum" showcasing the "Great Connection."
* Compare the pentadactyl limb (human hand, bird wing, bat wing, forelimb of a horse). Contrast
this with analogous structures like the wings of a butterfly vs. a bird.
* Activity: Use sketch-noting to create a map showing how one basic bone structure was modified for
flying, swimming, and running.
3)Students "adopt" a specific group (e.g., Group 1: Alkali Metals or Group 17: Halogens) and create a
travelogue.
* Content: The Family Portrait: Common physical and chemical characteristics of the group.
* The Pioneers: Who discovered these elements (Dobereiner, Newlands, or Mendeleev’s role)?
* Real-World Utility: Where do these elements live in our daily lives? (e.g., Lithium in batteries,
Sodium in salt).
•Students can use flashcards for each element in a group, listing its "personality traits" (reactivity,
state at room temperature).
All the parents are requested to ensure the completion of Holiday Homework during the vacation as
every work assigned ,carry marks.
