Chapter 5: Big Predators

Exciting, hands-on, inquiry investigation

The Splash Secondary Curriculum is exciting and fun for the environmentally conscious students.  I had a blast with my students studying the macroinvertebrates, watching the DVD, and hunting throught the BMI Guide to take notes on what we had found and how it related to water quality.   I look forward to more exciting, hands-on, inquiry investigation next year with my Biology students.

Bacteria made life possible on Earth

For 2 billion years, bacteria were the only creatures on Earth. Long before the dinosaurs, a special type of bacteria slowly increased the level of oxygen in the Earth's air to 20 percent. Without this oxygen other plants and animals could not have evolved, including us.
