Goat Roast

With all their new knowledge about our ancestors and the tools they used, students got to make their own stone tools! Knapping -manipulating stone to create a tool - is not as easy as it sounds. Its a real art because you need the right stones, the right force, and need to know where and [...]

Yesterday students went to a site rich in pottery shards, ostrich egg shells, stone tools and beads. Even though is was hot, the numerous artifacts that were easily spotted on the sandy surface, made for an exciting afternoon. The site was characterized by large silvery sand dunes and a beautiful vista of Lake Turkana.  The exact age [...]

Alternative energy, Turkana-style

Local students went back to visit the Lorengelup primary school where they planted trees a few weeks ago. They had since erected some barriers around these little trees to protect them from the many goats in the area.  Associated with the school is a small brand new maternity clinic.  To provide power for lights, cooking [...]

How do Plant Fossils Form?

Students learned in detail about how decaying organic plant material gets preserved over time (taphonomy). For example, plants can get preserved under volcanic ash, mud slides, or on lake and river bottoms. In all cases, fine sediment or ash completely covers the plant material.  To illustrate taphonomy, students went to the river to look at [...]

Leaves, Stems, and Pollen

This week, students will be learning al about the differences among living plants and their adaptations.  Did you know that there are many more plants with toothed leaves in colder climates and that most leaves of plants in warm and wet climates have smooth edges? There is a higher rate of photosynthesis in the spiky [...]
