ScienceProject: Topic-Organic Food: Good for you! Good for the Earth!Instructions:Make the project given below in a file using colourful A4 sheetsMethodology:-Students will go through their kitchen and see if there are any food items which havebeen labeled as organic in their homes. They should also see if this food is locallysourced or not.-Students will use the internet, books, magazines, especially newspapers for the latesttopics on organic food. File these articles .-In the research students have to focus on the following topics:1. Types and examples of organic food.2. The environment benefits of farming organic food.3.Health benefits of consuming organic food.4. How the organic food market works and how to identify organic food.5. What is sustainable farming?Activity-1Visit a nearby grocery store that sells organic food items. Make a list of these itemsand their price. Compare these prices with the locally obtained similar items.Prepare a questionnaire of 5 questions to interview the shopkeeper or record theinterview. Click pictures of the grocery store with the owner’s permission.Before independence, organic farming was practiced in India. With the onset of theGreen Revolution, chemicals are being used in the form of fertilizers and pesticides.Today, we are slowly reverting back to organic farming. Research and give 5comparisons between chemical and organic farming.We are revertingActivity-2Poster:Make a colourful poster on A4 sheets on organic food and its benefits.Assessment criteria:Research and content-5marksPoster -2 marksPresentation-3 mark

Class IX-ScienceAssignment-1

Do the following assignment on ruled sheets and file the sheets in the projectFile.

1. Give reasons for the following:a. Wet clothes dry quicker in sun than in shade.b. We feel uncomfortable when the humidity is high.c. Trees acquire more leaves in summer.2. Name two gases that are supplied in compressed state in homes and

in hospitals.3. Is evaporation an exothermic or endothermic process? Explain.4. Why do liquids flow? Explain.5. Particles in steam at 373K are more energetic than those in water at

the same temperature. Why?5. Draw well labeled diagrams showing electron microscopic structures of

plant and animal cell.6. At what temperature does water have maximum density? Why?7. Draw the following graphs:

a. distance-time graph for an object that is at rest after moving a certaindistance.

b. velocity-time graph of an object moving with a constant velocity.8. A car starts from rest and moves along the x-axis with a constant

acceleration of 5m/s2 for 8 seconds. If it then continues to move with aconstant velocity, what distance will the car cover in 12 seconds since itstarted from rest?

9. The brakes applied to a car produce an acceleration of 6m/s2 in theopposite direction to the motion . If the car takes 2 s to stop after theapplication of brakes, calculate the distance it travels during this time.

10. Give two similarities between mitochondria and chloroplast.11. How are vacuoles important for plants and single celled organisms.

P S A12. When we supply heat energy to water, particles start moving even faster.

At a certain temperature, a point is reached when the particles have enoughenergy to break free from the forces of attraction of each other. At this temperaturethe liquid starts changing into gas. The temperature at which a liquid starts boiling atthe atmospheric pressure is known as its boiling point. Boiling is a bulk phenomenon.Particles from the bulk of the liquid gain enough energy to change to its vapour state.Based on your understanding of the above passage, tick the correct option in thefollowing questions .13.The boiling point of a liquid is :a) directly proportional to atmospheric pressureb) inversely proportional to atmospheric pressurec) independent of atmospheric pressure14. At its boiling point:

a) the temperature of the vapour is more than that of the boiling liquidb) the temperature of the vapour and the boiling liquid is the samec) the vapour is hotter than the boiling liquidd) the vapour and the boiling liquid have the same amount of heat

i) a and b (ii) b and c( iii) c and d (iv) a and d.15 . In a pressure cooker, water boils at a temperature :

a) equal to 100o Cb) less than 100o

c ) more than 1000 C
