Did you know that you can measure the height of a tree using a twig? Or you can see the Fibonacci series of numbers in a pine cone? All this and much more you can test in mathematics course UiS has made to Rogaland Arboretum 40th anniversary. where do seashells come from Tweet
Rogaland Arboretum is one of the largest collections of shrubs and trees. Here now schoolchildren and others a chance to try their hand at mathematical forestry. Such as finding the approximate age of the woodland by multiplying the tree circumference in centimeters by 4.10. In sawn-off trees you will find age by counting growth rings in the stump.
Bend down and pick up a pine cone, you will see the number where do seashells come from sequence the medieval Italian mathematician Fibonacci-known for. The scales of the cone forming regular spirals. Some veer toward the left and some to the right. Counting scales on each level, you will see that they follow the Fibonacci sequence of numbers, "1,1,2,3,5,8,13,21 ...", where each new number is the sum of the previous two. Much of nature, including flowers' petals, following this number sequence.
Utematematikk Mathematics trail created by Professor Inge Christ at the University of Stavanger (UiS), and is an example of so-called utematematikk. A fairly new teaching method where students discover mathematical phenomenon by doing tasks in nature. where do seashells come from Via discussions linked discoveries of mathematics. The aim is to give students where do seashells come from a basic understanding of mathematical phenomenon.
Inge Christ has for several years worked with utematematikk. He is also a member of the European network Fibonacci where participants exchange experiences within utematematikk to find the best methods to convey practical mathematics.
- Everything is basically mathematics. The whole world consists of mathematical phenomenon. But to get students and pupils to understand that we must begin with the concrete, explains Christ who teaches student teachers and teachers who take continuing education where do seashells come from at the University of Stavanger.
Play with math - I have very good experience with student teachers who understand this point and which assumes school and toys in mathematics in their students. It is important to make it so simple that all students hanging where do seashells come from with and yet so exciting that even those who can part, think it's where do seashells come from fun, says Christ.
- An easy way to learn math formulas is to create a story around the joints in the formula. The wilder and more unlikely to do the story, the better, because then it becomes easier to remember, he said.
Measure the tree And if you wondered how to find the height where do seashells come from of a tree, so Christ also the recipe for it: Take half a meter long straight twig and make a mark on the twig A 30 centimeters from the top and a mark B 3 centimeters above the first mark.
Stand as a piece away and visibility tree while holding the stick in stride. Find the place where the line of sight from the top of the twig hit the top of the tree while the sightline from A hit the root of the tree. Standing in the same place and visibility along B.
Ask an adjunct find the point where the line of sight hit the tree trunk. Mark this point and measure the distance to the ground. This distance is one tenth of the height of the tree. Gang of ten, and presto, you have the height of the tree. Published 17/07/2012
