An Introduction to Forensic Science' we delved into the day-to-day activities and tasks of real-life forensic scientists and compared these with typical TV stereotypes. But before you draw a conclusion that specialist forensics work must be dull, let?s put on our lab coats and get involved in the forensic investigation of a mock-up crime!

Understanding the world around us can be a real adventure! That's the message in this 11-part series for children in grades K-4. Kids travel along as our young host explores the world of physical science and how it can be seen, touched and understood in everyday life.

In Planet Earth, we brought you the world as you've never seen it before. Now, get closer with Life.

"The basis for modern day genetics was discovered in a 19th century Austrian monastery garden containing peas, and tended by a keenly observant monk named Gregor Mendel, who had training in mathematics and biology. Mendel cross-pollinated plants with 2 differing traits, a strain of homozygous wrinkled and yellow peas, with homozygous round and green peas, for two generations.

As background, a brief history is presented of what new information caused the classification of living things to evolve from the original 2 Kingdom classification of Animals and Plants by Linnaeus in the 18th century to the present day 6 Kingdoms: Animal, Plant, Fungi, Protista, Eubacteria, and Archaebacteria.

The key concepts in Part 1 are briefly reviewed. Organisms in the Protista Kingdom are virtually all single-celled. Most are heterotrophic, some are autotrophic like algae, a few like euglena are both. Most reproduce asexually, but occasionally some also sexually which produces genetic variation and long term evolutionary benefits.

The astronomer Hubble laid the foundations of the Big Bang Theory of the universe in 1929 when he found that distant galaxies were receding from the earth. The theory holds that the origin of our universe was some 14 billion years ago in a cataclysmic explosion of radiant energy of unknown cause, which formed into atomic particles of hydrogen and helium.

In the six kingdom classification, the Protista Kingdom contains all single celled organisms which are eukaryotic, meaning which have a nucleus. They are called protists.

The western world has built its affluence on fossil fuels. Our addiction to coal and oil is no longer healthy neither for mankind nor the planet. So the question is, how do we replace fossil fuels?

Euglena is a protist whose behavior is both plant-like and animal-like (protozoan). Structures Like a mobile protozoan, its structures include a flexible outer membrane called a pellicle (not a plant-like rigid cell wall), and a flagellum for locomotion).
