Science : Roots

We started out our study of roots by reading from Exploring Creations with Botany. After that, it was intensive work producing mini books and notebook pages for this chapter. Look at our work zone...

Here are some notebook pages that we added into our botany file. This page shows a flap book where the boys narrated what they have learnt about roots; their functions, development and morphology.

Our attempts in trying to make a mini tab book on geophytes (as mentioned in our Botany book) led us to google search for pictures. We found useful diagrams for our geophyte mini book here.

We chanced on a wonderful blog that has an interesting root word search that the boys insisted on doing. There were terms in this word search that were unfamiliar to us. This led us to google search for what these terms mean. In the process we learned about adventitious roots and the various types of adventitious roots. (Good information on adventitious roots can be found here.) We decided to make a notebook page on adventitious roots.

This site clearly explains how a fig tree starts off having aerial roots and how it gradually takes over its host with its strangling roots.

As we read up more on adventitious roots, we noticed that mangrove trees have specialized roots to adapt to their unique environment. This site has some good information on this.

At this point, I was getting excited because in a few days' time, the boys will be attending a Naturalist Camp in Sungei Buloh Wetland Reserve (a mangrove area). All these readings about mangrove trees will serve to gear them up for the camp. What perfect timing!
