In How Old is a Tree you will examine tree rings to determine the age of the tree when it was cut. You will also learn to interpret the climate conditions the tree experienced during its lifetime. The second lesson focuses on how seeds travel. Plants cannot move but need to spread and reproduce in order to make sure that they live on. The language booster provides an introduction to the topic by describing what seeds are and how they disperse. Almost half of all the trash produced by humans today is paper products, so recycling paper is an important part of overall recycling efforts. Reusing and recycling paper is one small step we can all take to protect our environment for our lifetimes as well as for future generations.
