   E1. Forensics

   Sep 19, 1997 · 26m

   Forensic scientists try to find out the who, what, when, where, and why of events in the past – crimes. Most forensic scientists work in police labs. They collect evidence from the scene of a crime and analyze the evidence in a lab. Forensic scientists look for clues that will help them solve a crime. Fingerprints, footprints, hair, blood, and traces of gunpowder can be helpful evidence. Forensic scientists use all sorts of scientific instruments to analyze even the smallest bit of hair or the tiniest chip of paint. By scientifically testing evidence from the crime scene, and by knowing about evidence from past cases, forensic scientists can piece together what happened, to figure out who did what, and to help police catch a criminal.

   E2. Space Exploration

   Sep 26, 1997 · 26m

   Space is hard to explore, because it’s really, really big. Most things in space are so far away that people we build special equipment just to see them. We use telescopes to magnify far-away solar systems, planets, and stars. Rockets send astronauts past the Earth’s atmosphere. Space probes with special cameras send back pictures of planets for scientists to study. Astronauts perform experiments in orbit around the Earth. We do all these things and more to learn more about our universe.

   E3. Genes

   Oct 17, 1997 · 26m

   The color of your eyes, the shape of your nose, and the straightness (or curliness) of your hair depend on your genes. Not jeans the pants, but genes, the long strands of chemicals in your cells. Genes are like a blueprint for your body, and your cells follow the blueprint to build you. All living things have genes in their cells. You get your genes from your parents – half from your mom and half from your dad. Your parents got their genes from their parents, your grandparents. Living things pass down their genes from generation to generation. Genes from a mother’s egg cell mix with genes from a father’s sperm cell to make a complete set of plans for a baby. Baby humans, baby dogs, and baby plants all grow up to look like their parents because of genes.

   E4. Architecture

   Oct 24, 1997 · 26m

   Towers, teepees, castles, and condominiums – some kind of planning goes into all buildings, no matter how big or small. Architects are people who design buildings, and the areas around buildings. Usually architects draw on a computer or a big desk (a drawing board). The plans show the dimensions of all parts of a building. Architects try to design with the purpose of the building in mind, but even buildings used for the same thing can look very different.

   E5. Farming

   Oct 31, 1997 · 26m

   Before food gets into your kitchen, before it even gets to the store, it’s on a farm. Almost everything we eat is grown on a farm, an area of land used to raise animals and plants. Farming nowadays can get pretty complicated. Farmers are scientists – agricultural scientists. Farmers work hard to keep their farms healthy. Soil is stirred up to get oxygen to the microorganisms that live in between the grains and to plant roots – that’s called tilling the soil to aerate it. Plants need to be protected from pests with either chemical pesticides or biological pesticides. Animals like bats and friendly insects eat other pest insects (chomp,chomp). Animals are milked, corralled, fed, sheared, slaughtered or cleaned-up after.

   E6. Life Cycles

   Nov 14, 1997 · 26m

   My, how you’ve grown! The popular exclamation from your Auntie may be no great revelation, but growing bigger is a part of life. In fact, it’s part of the whole cycle, or pattern, of human life that began with your birth. The different stages in life are called life cycles. Humans aren’t the only ones with life cycles. At first, you might think that you have nothing in common with a cactus in the desert, or a fish in the sea, or the mold in your gym shoe, but you do. You’re all alive. You all have or will experience birth, growth, reproduction, aging, and eventually, death.
