Week3 Celebrate your holidays with an impressive POSTER MAKING IDEA! Just grab your supplies and get started with the simple instructions below and make an attractive poster on any one of the following topic- 'Benefits of exercise ' or 'Say No to Junk Food'. Add your information as text boxes/wordart from the Drawing toolbar with borders. Re size them if necessary. Insert relevant pictures/images from Internet.(Using cut-copy-paste option) Explore the Formatting options and tools to design your layout. When you are finished, take its coloured print out... Week 4 Science Quiz 1. What is chalk? 2. Which force pulls objects towards the centre of the Earth? 3. What hard substance protects teeth from decay? 4. How many canine teeth does and adult human have? 5. Name 3 food types which should be included in a healthy diet. 6. Name 3 foods which you should not eat too much of if you want to stay healthy 7. How are igneous rocks formed? 2
8. Which is heavier: 1 kg of feather or 1 kg of rock? 9. Draw three weather symbols. Find out what they mean. 10. Name 3 countries where there are volcanoes... Week 5 Use rocks to make a water filter. In a funnel put some charcoal, clean sand on top and rocks on top of that. Then put some water through and see how it comes out. Demonstrate this in class when you return in September after your holidays. Or Keep a log of the different soils you find in your holiday country or your local area. For example.. What colour is the soil? What is the soil made up of? Can you describe the texture? What are the particle sizes? 3
Week 6 Make a String Telephone What you'll need: 2 paper cups/cans A sharp pencil or sewing needle to help poke holes String (kite string and fishing lines work well) Instructions: 1. Cut a long piece of string, you can experiment with different lengths but perhaps 20 metres (66 feet) is a good place to start. 2. Poke a small hole in the bottom of each cup. 3. Thread the string through each cup and tie knots at each end to stop it pulling through the cup (alternatively you can use a paper clip, washer or similar small object to hold the string in place). 4. Move into position with you and a friend holding the cups at a distance that makes the string tight (making sure the string isn't touching anything else). 5. One person talks into the cup while the other puts the cup to their ear and listens, can you hear each other? What's happening? Speaking into the cup creates sound waves which are converted into vibrations at the bottom of the cup. The vibrations travel along the string and are converted back into sound waves at the other end so your friend can hear what you said. Sound travels through the air but it travels even better through solids such as your cup and string, allowing you to hear sounds that might be too far away when traveling through the air. Read the below fun facts related to animals. Research and list 5 more fun facts related to living things. Rabbits and parrots can see behind themselves without even moving their heads! Butterflies taste food by standing on top of it! Their taste receptors are in their feet unlike humans who have most on their tongue. Although the Stegosaurus dinosaur was over 9 metres long, its brain was only the size of a walnut. A hippopotamus may seem huge but it can still run faster than a man. 4
Sneezing with your eyes open is impossible. MY RESEARCH: FUN FACTS IN SCIENCE Animal Camouflage While some of us stand out in a crowd others tend to blend in and it s the same in the animal kingdom. This animal camouflage lesson plan explains some of the concepts and offers a fun activity to help kids understand how camouflage works. Camouflage Information: The color and/or pattern of an animal often allows it to either blend in or stand out from its environment. This helps them escape predators or hunt more efficiently by being harder to see. When it blends into its background it is called camouflage. For example, many animals that live in snowy areas are white, like the polar bear. Many animals that live in deserts are sand-colored, many animals that live in trees are green, many animals that live on rocks match the coloration of the rocks and many animals that live near the soil are soil-colored. Patterns, like stripes or spots, can also help camouflage an animal. A chameleon can even change its colour to blend in with its environment. Animals that stand out are often colored very brightly; this is because in the animal world a bright color means danger or poison. Take a look at some animal photos, which animals are camouflaged and which stand out from their surroundings. 5
Make a cardboard cutout of an animal and color it with markings so that it camouflages into the color of your room. Questions: What is it called when an animal blends into its environment? What are two reasons why an animal will blend into its environment? What are two ways an animal can blend into its environment? Week 7 Recycling Activities What type of things do we recycle? Bottles, paper, newspaper, plastic containers, aluminum cans etc. Why do we need to recycle? Increasing population and an over reliance on products and packaging leads to too many landfills (there is only so much we can dump in the ground.) We need more things that we can reuse more than once. What are some other good things we can do apart from just recycling? Reduce, Reuse, and reinvent. These ideas, along with recycling, are very important when it comes to humans looking after the planet. Reduce: The most effective way of managing waste is not to produce it in the first place. By not buying packaging we save things from being thrown out. Always look out for packaging that is recycled. Buy things from places that use fewer containers or let you use your own recycled ones. Reuse: This is the continued use of a product in its original form. For example, instead of throwing out your old microwave when you get a new one, you could sell it at a garage sale or trade it in. Try and use containers, plastic bags and newspapers as many times as possible. Reinvent: This is when you make new, useful things from recyclable objects. For example, using old plastic containers as lunch boxes, making crafts from old boxes and containers, making jewelry boxes from old containers, making original toys and dolls out of unwanted objects or even making costumes from recycled material. Recycle: Wash, squash and recycle. Fold up old newspapers and tie them together. Make old things into new or different products. Activities - Try some of these fun recycling activity ideas Make paper figurines or origami from scrap paper. 6
Make something from ice cream sticks (e.g. a pen holder, model building, fan or photo frame). Make a poster that shows good ideas for recycling and reducing waste. Make a jigsaw puzzle out of old, unused items. Week 8 Research to find information about any two of the following. Make an A3 size colourful poster with relevant information and illustration. Submit it when school re-opens: a. Hyper loop Train (How it works) b. International Space Station c. Endangered animals d. Hydrophonic farms in UAE 7
