Information
In the botanical garden, there is a collection of many different species of deciduous trees. Deciduous trees have broad leaves that change color in the fall and spread their seeds using flowers. They are a natural source of building material. Oak wood has a density of 0.75 grams per cubic centimetre, which is more than ash wood that contains 0.55 grams per cubic centimetre and elm wood 0.6 grams per cubicmeter. Therefore, oak wood is regarded as the most durable and strong wood material. Discuss with your groupmates which kind of things can be built from different woods.
