ENGLISH India is a magical land of beauty and serenity.” Let’s know about the creative and talented souls living in this magical land. 1. Prepare a digital display of people of Coorg/Goa/Assam/Benaras (any one) their lifestyle including geographical features. Include the pictures and the information of the famous tourist destinations also. Presentation of the ppt will be conducted after the summer break. 2. A travelogue is the detailed description of writer’s perception, impressions and comments about attractions of places, as they travel from place to place. It’s the journal which provides the insights of writer’s feelings and experiences. TIPS FOR WRITING AN EXCELLENT TRAVELOGUE ● Research the place ● Write descriptively ● Highlight the various attractions ● Mention the ways and means to reach the destination ● Mention some out of the way and means to reach the destination ● Give some cultural background ● Mention some Dos and Don'ts of the place ● Paste pictures ● Make it colourful and attractive Based on the above given points write a travelogue on any one of the given places in

WEEK 8 AGE 9 - 14 YRS HERITAGE PHOTOFRAME MATERIAL FEVICOL A+, FEVICRYL ACRYLIC COLOUR, NEWSPAPER, ANY CORD, MIRRORS, FINE ART BRUSHES, OHP SHEET, PENCIL, ROLLING PIN, PAPER CUTTER,PLASTIC SHEET Buy all the products needed for the workshop by clicking here https://www.bit.ly/3ahtllo

To make papier mache pulp, take a bowl and make a mixture of newspaper pieces and Fevicol A+, make sure to mix it well until you get thick glue-like consistency. Add bit of water if it's too thick. To get proper result keep the mixture for 24 hrs approx. To create photo frame, take white coloured chart paper draw any heritage design as shown with the help of pencil. Now trace out contour design onto ohp sheet and cut it with the help of paper cutter, now place a plastic sheet and create a slab with help of rolling pin as shown. Make sure surface is even from all the sides Now place the ohp cut out onto the slab as shown Once semi dried, cut it with the help of paper cutter.

Using paper Mache create elements following the design drawn make sure elements done are symmetrical. Using Fevicol A+, stick each element as shown Using Fevicrly Acrylic Color white, paint it as base coat with the help of fine art brushes and let it dry Using Fevicryl Acrylic colour of your choice paint it with the help of fine art brushes. To enhance decorate it with mirrors and other embellishments using Fevicol A+. Now take any cord create a loop and hook it from behind.
