Students examine the three domains of life and explain that all living things share a common ancestor.  In this paleontology lesson students are introduced to the process of illustrating evolutionary relationships. 

In this biology worksheet, students identify and match various classes of species found today. Then they explain why biodiversity exists today on earth and define evolution. Students also describe who a paleontologist is and what they do.

Students explore the classification system of organisms: taxonomy. They examine prepared slides of Protozoans and record information on a Taxonomy Recording Sheet. Two additional classifying activities are also included in this lesson.

Students study chloroplasts, their structure and evolution.  In this photosynthesis lesson students experiment with polarized light and the production of chlorophyll.

In this online interactive English vocabulary skills worksheet, students respond to 13 multiple choice questions that require them to fill in the blanks in sentences with the appropriate prepositions.
