Activity 4.1 Class 10 Science – Explanation

We use many things in daily life from morning to evening. In this activity we will find out what all these things made of.

 

Aim of the activity

To make a list of things that are used in daily life and find out used material they are made from.

Materials Required

    1. Pen and notebook

    2. Chart

    3. List of 10 items

 

Procedure

 We will follow the below steps:

   1.  We will make a personal list of 10 things that we use or consume from morning to evening like- toothpaste, breakfast, notebook etc.

   2. We combine our list with our classmates’ list to create an extensive list.

   3.  Now we sort each items into three categories – (i) Metal (ii) Glass/clay and (iii) other items

   4. If an item is made of more than one material, we categories them in the all relevant columns.

    

    Observation

 We can see that most of things made of carbon such as plastics, food, fuels etc.

 

Explanation

Most of the things that we use are made of carbon because carbon has ability to form bonds with many elements. So, carbon found in many compounds.

    1.  Food (carbohydrates, protein, fats)

    2. Fuel (petrol, diesel, LPG)

    3. Plastic (tyos, bottels)

    4. Cosmetics (soap, shampoo)

    5. Fabrics (cotton, nylon)

Conclusion

Most of the utilities which we use in our daily life are made up of compounds of carbon.

This activity helps understand that a large number of things we use are made of carbon compounds and this activity show the versatile nature of carbon.

Frequently Asked Questions

   1. Why are carbon compounds so common in daily life?

Answer – Carbon atom forms covalent bond with other carbon and other elements and form a large chain so it is found in many compounds.

   2. Is plastic a carbon compound?

Answer – Yes, plastic is made of polymers of carbon molecules.

   3. Why are food items considered carbon compounds?

Answer – Food items contain carbohydrate, fats and proteins and these are all organic compounds made of carbon.
