ITL PUBLIC SCHOOL WINTER HOLIDAY HOMEWORK (2020-21)

CLASS VII

ENGLISH

1. DESIGNING A STORYBOARD

A storyboard is a graphic organizer that consists of illustrations or images displayed in sequence for the purpose of pre-visualising a motion picture, animation, motion graphic or interactive media sequence.

Students are required to read any one of the stories based on one genre (Refer to the illustration given below) and create a colourful E- STORYBOARD using Powerpoint or template from canva.com

Read the instructions given below:

STEP 1 – Read the story STEP 2 – Write the story in your own words in about 150 – 200 words. STEP 3 – Give a suitable title to the story. STEP 4 – Create a storyboard based on the story written (Refer to the sample while creating the story board. · Font – Use your creativity · Font Size – 12 · Write the heading/ title in bold. · Make it colourful

Topic: Visualising solid shapes

Plane Figures

(2-Dimensional Shape)

The figures which we can draw on a flat surface are called Plane Figures. They have two dimensions i.e. length and breadth, hence these are called 2 Dimensional Shapes.

Solid Figures (3-Dimensional Shape)

The figures which have three dimensions i.e. length, breadth and height are called 3 –Dimensional Shape. They occupy some space. Like the ball, box, tube etc.

Faces, Edges and Vertices Faces – All the flat surfaces of the 3-D figure are the faces of that shape. The faces of 3D shapes are made by the 2-D shapes.

Edges – The line segment where the faces of the 3D shape meet with each other are the edges of that shape. Vertices – The corners or the points where the edges meet with each other are the vertices of the 3D shape. The singular form of vertices is the vertex.

No. of Faces, Edges and Vertices in some common 3- D Shapes

Nets for building 3 – D Shapes

If we draw the structure on the 2D form and fold it to make a 3D shape then it is said to be the net of that figure. Different figures have a different type of nets.

We can open a 3D shape from its edges to get the net of that figure.

Drawing Solids on a Flat Surface (2D representation of 3D Shapes)

As you know that the 3D shapes are the shapes which occupy some space but we can draw the 3D shapes on the flat surface also by some techniques. This is called a visual illusion.

1. Oblique Sketches

When we draw a shape in such a way that we are not able to see some of the faces of the 3D shape and the size of the length is also not equal but we are able to recognize that this is a cube then this is called an Oblique Sketch.

Steps to draw an Oblique Sketch

Draw the sketch of a cube with a side of 4 cm each.

Step 1: First, we need to draw a square of 2 × 2 on a grid sheet.

Step 2: Draw the opposite face of the same size which is offset to the front face.

Step 3: Now, join the respective corners, to form a cube.

Points to remember for the oblique sketch- The front and back faces are of the same size.

All the edges are appearing as of the same length but their measurements are different.

2. Isometric Sketches

The isometric sheet is the sheet made up of dots which makes the equilateral triangles. When we draw the shape on the isometric sheet with the measurements proportional to the original figure then it is said to be Isometric sketch.

Visualizing Solid Objects

When we see any 3D shape from one side then some of its parts are not visible to us. But then also we can assume that which shape it is, this is called Visualization.

We can see that the front, top and side view of the above image is completely different and we cannot see some of its faces then also we can say that this figure is made up of four cubes.

Assignment

Q-1 Match the following:

Q-2 What cross-section do you get when you give a horizontal cut to an ice cream cone?

Q-3 Determine the number of edges, vertices and faces in the given figure.

Q-4 Write down the number of edges on each of the following solid figures:

(i) Cube

(ii) Tetrahedron

(iii) Sphere

(iv) Triangular prism

Q-5 Name any three objects which resemble a sphere and cone.

SCIENCE

Activity-Herbs that Heal

Plants have been used for medicinal purposes long before the prehistoric period and in present scenario medicinal plants and herbs play an important role in curing, healing and developing strong immunity. Nowadays, herb refers to any part of the plant like fruit, seed, stem, bark, flower, leaf, stigma or a root, as well as a non-woody plant. The best thing about them is that they can be grown easily in our compact kitchen gardens at home.

Collect information about 10 such herbs or medicinal plants in the given format and try to incorporate their usage in your daily life for better health. Present your findings on an A4 size sheet /ppt with pictures of plants.

Ch-14 Electric current and its effects (Do the following questions in your Science notebook)

Q1. Rahul does not have a night lamp in her room. He covered the bulb of his room with a towel in the night to get dim light. Has he taken the right step? Give one reason to justify your answer.

Q2. Why do we cover plug pin holes which are within the reach of children with cello tape or a plastic cover when not in use?

Q3. Why are compact fluorescent lamps (CFLs) preferred over electric bulbs?

Q4. Copper and aluminium wires are usually employed for electricity transmission. Explain the reason.

Q5. State one measure to avoid overloading in an electrical circuit. Also mention the name given to a situation in which the live and the neutral wires accidently come in contact. Describe the role of a safety device in this situation.

SOCIAL SCIENCE

The United Nations projects that the total number of persons suffering from severe food insecurity has been on the rise since 2015, and there are still millions of malnourished children. The economic slowdown and the disruption of food value chains caused by the pandemic are exacerbating hunger and food insecurity.

Group A (Odd Roll Numbers)

· Reflect on the steps that can be taken to reduce food insecurity. Think what steps can be taken by the government, Catering service providers, online food delivery platforms, Restaurant owners, school agencies and media. Create an E-pamphlet with concept maps to represent your innovative thoughts.

Medicinal Plant/Herb 1.Tulsi (Basil)

Importance

Tulsi is called the queen of all herbs. Tulsi can help you get rid of many health problems ranging from fever to kidney stones. Ayurvedic texts have also categorised the wonder herb as a stimulant, antipyretic and aromatic in nature. Tulsi eyewash can also reduce strain on your eyes.

Learning outcome: Students will be able to: · Understand the meaning of food security · Relate the issue to sustainable development goals · Discover innovative steps that can bring a change in the way food is wasted · Design the e-pamphlet using concept mapping

Group B (Even Roll Numbers) · It seems quite strange, but the distance your plate of food travels is likely to be

more than you will travel in a whole year! And, to think – in some countries some of it even ends up in the bin!

Find out the distance travelled by your favourite dish to reach you. Reflect upon how you should treat the food that you are receiving. Hints: 1) Find out the major ingredients in your dish. 2) Research the most important producing state of each ingredient. 3) Calculate the distance between the producing state and your state. 4) Calculate the total distance Represent your report with infographics.

Learning outcome: Students will be able to:

· List the various ingredients in their favorite food

· Discover the agricultural uniqueness of each state of India

· Apply simple mathematics to calculate the distance travelled by the food to reach the consumer

· Reflect on the issue of food wastage · Design a report using concept mapping and computer graphics

Criteria for evaluation: Creativity, Presentation, Timely submission
