Heres all we need to know about trees

Except theres not much here



It might help to keep in mind the metal objectives in science when judging trees and determine what factors might be important when different trees and their woods

OC6 recall that woods do not conduct electricity or heat

OC7 identify everyday applications of wood, for example in industry,

Native Irish tree species

The native oaks, Sessile Oak (Quercus petraea) and Pedunculate Oak (Quercus robur), Ash (Fraxinus excelsior), Wych Elm (Ulmus glabra), The native birches, Silver Birch (Betula pendula) and Downey Birch (Betula pubescens), Black Alder (Alnus glutinosa), The native cherries, Common/Wild Cherry (Prunus avium) and Bird Cherry (Prunus padus), Aspen or Trembling poplar (Populus tremula / tremuloides), The native willows, Goat Willow (Salix caprea), Grey Willow (Salix atrocinerea), Bay Willow (Salix pentandra) and Eared Willow (Salix aurita), Mountain Ash or Rowan (Sorbus aucuparia), Whitebeam (Sorbus hibernica), Crab apple (Malus sylvestris), Yew (Taxus baccata), Juniper (Juniperus communis), Scots Pine (Pinus sylvestris), Blackthorn/Sloe (Prunus spinosa), Hawthorn (Crataegus monogyna) ,Killarney Strawberry Tree (Arbutus unedo)

OC9 recall the symbols of the non-metallic elements C, O, S, H and N are all in wood

OC10 understand that woods are not shiny (lustrous),

can be carved into shape

and can become swollen and dry out

OC11 understand that different trees produce different types of wood that have different properties relative abundance and therefore are used for different objects

OC48 describe the general properties of the hard woods, soft woods, wood composites

OC49 describe the reactions of the woods with air and water (word equations for reaction with water)

OC51 investigate the reaction between zinc and HCl, and test for hydrogen (word equation and chemical equation)
