FORMATIVE ASSESSMENT -I (2023-24)

GENERAL SCIENCE 

(English Medium)

CLASS: 10

(Maximum Marks: 20) Time: 60 Min

PART-A (Physical Science) 

I. ANSWER THE FOLLOWING QUESTIONS.

1. State the difference between Virtual and Real images?

Ans. Virtual Image

• Light rays do not actually meet, but appear to meet behind the mirror or lens.

• It is always upright.

• It cannot be projected onto a screen.

• It is formed by diverging light rays.

Real Image

• Light rays actually meet at a point.

• It can be projected onto a screen.

• It is always inverted.

• It is formed by converging light rays.

2. Name the base present in antacid tablets?

Ans. 

Bases in Antacid Tablets

The most common base present in antacid tablets is magnesium hydroxide. Other bases that are sometimes used include aluminum hydroxide, calcium carbonate, and sodium bicarbonate.

II. ANSWER THE FOLLOWING QUESTIONS. (A & B) X2M=4M

3. (A) Draw ray diagram for the Convex lens when object is placed at F₂

(B) By Observing the following table. Answer the following questions?

1. In which material speed of light in high?

Ans. Ice 

2. In which material, speed of light is low?

Ans. Carbon Disulphide

III. ANSWER THE FOLLOWING QUESTIONS. 1X4M = 4M

4. Write the factors that effect the process of evaporation. Explain with suitable examples?

Ans. Temperature: The higher the temperature of the liquid, the faster the rate of evaporation. 

ex. water will evaporate more quickly on a hot day than on a cold day.

Surface area: The greater the surface area of the liquid, the faster the rate of evaporation. 

Ex. a puddle of water will evaporate more quickly than a cup of water with the same amount of water.

Humidity: The lower the humidity of the air, the faster the rate of evaporation

Ex. water will evaporate more quickly on a dry day than on a humid day

(OR)

Write the role of lenses on our daily life?

Ans. Magnifying glasses: Lenses are used in magnifying glasses to make objects appear larger. 

Cameras: Lenses are used in cameras to focus the light from the scene onto the film or sensor

Microscopes: Lenses are used in microscopes to magnify objects that are too small to be seen with the naked eye.

Telescopes: Lenses are used in telescopes to magnify objects that are far away

PART-B (BIOLOGICAL SCIENCE)

I. ANSWER THE FOLLOWING QUESTIONS.

1. Expand NADPH

Ans. NADPH stands for nicotinamide adenine dinucleotide phosphate

2. What happens if blood capillaries are absent?

Ans. If blood capillaries are absent, then the tissues will not be able to get the oxygen and nutrients they need to function properly. This can lead to a variety of problems, including tissue death.

3. (A) Observe the given picture and answer the following questions.

1. What does this experiment indicate?

Ans. carbon dioxide is present in the air 

2. Which gas turns lime water milky?

Ans. Carbon dioxide is the gas that turns lime water milky.

(8) Write the events conducted in Chloroplast?

1) Conversion of light energy to chemical energy. 

2) Splitting of water molecule. 

3) Reduction of carbon dioxide to carbohydrates.

III. ANSWER THE FOLLOWING QUESTIONS.

4. Explain the procedure of the experiment to prove that Sunlight is essential for Photosynthesis

Answer – 

Materials:

• A healthy green plant

• A piece of black paper

• A pair of scissors

• A beaker of water

• A dropper

• Iodine solution

Procedure:

• Keep the plant in a dark room for 24-48 hours. This will ensure that the leaves are depleted of starch.

• Cut a piece of black paper to fit over a leaf of the plant. Make sure that the black paper covers the entire leaf, including the edges.

• Secure the black paper to the leaf with a piece of tape.

• Place the plant in a sunny location for 3-4 hours.

• Remove the leaf from the plant and carefully peel off the black paper.

• Boil the leaf in a beaker of water for 10 minutes. This will decolorize the leaf and remove the chlorophyll.

• Allow the leaf to cool.

• Use a dropper to apply a few drops of iodine solution to the leaf.

Observations:

The areas of the leaf that were exposed to sunlight will turn blue-black. This is because the starch that was produced by photosynthesis reacted with the iodine solution. The areas of the leaf that were covered by the black paper will not turn blue-black. This is because no photosynthesis occurred in these areas.

Conclusion:

The results of this experiment show that sunlight is essential for photosynthesis. Without sunlight, no starch can be produced, and the leaf will not turn blue-black when exposed to iodine solution.

(OR)

What is meant by Hypertension? Describe its causes, Symptoms and control measures to relieve the condition.

Ans. 

Hypertension, also known as high blood pressure, is a chronic condition in which the blood pressure in the arteries is too high. This can damage the blood vessels and increase the risk of heart disease, stroke, and other health problems.

Causes of Hypertension

The exact cause of hypertension is unknown, but there are a number of factors that can contribute to the condition, including:

• Age: Hypertension is more common in older adults.

• Family history: If you have a family history of hypertension, you are more likely to develop the condition.

• Race: Hypertension is more common in African Americans, Hispanics, and Native Americans.

• Obesity: Being overweight or obese is a major risk factor for hypertension.

• Physical inactivity: Lack of physical activity can increase your risk of hypertension.

• Smoking: Smoking can damage the blood vessels and raise blood pressure.

• Excessive alcohol consumption: Drinking too much alcohol can raise blood pressure.

• Certain medications: Some medications, such as steroids, can raise blood pressure.

Symptoms of Hypertension

Most people with hypertension do not have any symptoms. However, some people may experience headaches, shortness of breath, chest pain, or fatigue.

Control Measures to Relieve the Condition

There are a number of things you can do to control hypertension, including:

• Losing weight: If you are overweight or obese, losing even a small amount of weight can help lower your blood pressure.

• Eating a healthy diet: Eating a diet that is low in sodium, saturated fat, and cholesterol can help lower your blood pressure.

• Increasing physical activity: Regular physical activity can help lower your blood pressure.

• Quitting smoking: Smoking can damage the blood vessels and raise blood pressure.

• Limiting alcohol consumption: Drinking too much alcohol can raise blood pressure.

• Taking medication: If lifestyle changes are not enough to control your blood pressure, you may need to take medication.

Conclusion

Formative Assessment 1 (FA1) is a crucial evaluation component in the Andhra Pradesh 10th grade General Science curriculum. It helps assess students’ understanding of various scientific concepts and guides teachers in providing targeted support. By preparing well and understanding the sample questions provided, students can excel in the AP 10th General Science FA1 examination in 2023.
