Our rainforest has already started to grow in the classroom and will be added to, by us, using our art and maths scaling skills and when we discover more about rainforest vegetation and plant life - exciting stuff!
Rainforests cover only a small part of the earth's surface - about 6%, yet they are home to over half the species of plants and animals in the world! To start our new Rainforest topic using our superb map, globe reading and geographical skills, we began by exploring the location of the tropical rainforests around the world. Interestingly, we found that most were situated around the equator line and within the boundaries of the Tropics of Cancer and Capricorn.
Researching Non-Fiction Book Text Features, Presentation Methods and Layout Styles In Preparation For Making Our Own Rainforest Reference Material... What Wonderful Hard-Working Willows!
D.T Workshop - Part 2... CAM Mechanism Construction and Housing Unit Preparation for Building Our Final Moving Toys!
Please scroll down and see our earlier posts to find out more about what we've been constructing in our 'Inventions Unit'
One Willower's Brother Had Been Busy in Year 8 Building a Moving Toy - Thank You For Bringing In The Great Example!
After exploring patenting, the world of design and some crazy inventions, we completed a blue-print producing task for a Wallace and Gromit contraption competition. This was fab and gave us further understanding of the importance of detailed design. After, we began to put our practical engineering/construction skills to the test to design and construct our very own CAM mechanisms and moving toys - brilliant! As a further exercise, Miss Mack presented a problem for us to try to solve through invention: 'How can I travel the 3m to my bin at home, after making a brew, with my teabag on a spoon and avoid drip-age?' Answering the question involved building prototypes using recyclable materials. This meant superb team speaking and listening skills, further design application, presentation and persuasive abilities and consideration of materials for the suggested final product were all needed! Miss Bailey kindly helped to judge the winner! We had some very original and innovative designs - well done Willows!
Exploring Gravity, Mass, Weight and Air Resistance... 'Does a larger 'Weight' Increase the Speed/Gravitational Pull? Will the Heavier Items Land First?'
The answer was surprisingly... NO! The gravitational pull remains the same. After investigation, we discovered that air resistance worked against the force of weight and gravity to slow the object's speed of landing! We worked with sheets of paper, rolled paper, tennis balls, hockey balls and other heavier objects with the same surface area (air resistance.) The hockey, tennis and scrunched paper all landed at the same time, despite having different 'weights'. Importantly, we learnt that weight is a force that is measured in newtons and works hand in hand with the force of gravity. Mass is measured in kilograms or grams and is the amount of matter or 'stuff' it contains. The more matter, the greater the mass! This is why, when the force of gravity is low (like in space), a person can feel weight-less. In space, the person's mass would still be the same as they would still be made of the same 'stuff'! Some of us then felt that 'Weight-Watchers' needed to be re-named 'Mass-Watchers' - very interesting!
