DNA is found in the nucleus of cells. Our bodies are made of cells. Each person has a particular DNA in the nucleus of their cells. If you can get a sample of a person’s cells, like a hair or a drop of blood, you can see what their DNA looks like in a lab. A suspect’s DNA can be compared to DNA found at a crime scene.
In the game csi: Squeak Sneak, Fetch’s squeaky toy is missing. Look at the crime scene and collect evidence. Use DNA to finger the real culprit.
Now watch the Dragonfly TV Forensic Whodunnit Video: The Cake Caper. Somebody has tampered with a birthday party table. The investigators find fiber, saliva and fingerprint evidence at the crime scene, so they gather fiber, saliva and fingerprint samples from everyone they think is a suspect. Watch them analyze the evidence using a forensics lab to help solve the mystery.

If you love airplanes, try out some of these paper creations. If you understand how the forces of aerodynamics work, you can make a plane that flies far. In The Kids’ Guide to Paper Airplanes the directions are really clear with color photographs to help you make the folds correctly. The planes start out easy and get harder and harder as you move through the book. The last plane requires 18 folds! The author even includes some tips for getting these planes to fly far.
What You Need:
Do you know why paper airplanes fly? They fly because of the forces that affect movement on earth. These forces are thrust, drag, lift and gravity.
Here are some websites that will help you understand aerodynamics and how to make good paper airplanes:
Science Rocks! Fly a Dart (page 52) and Fly a Glider (page 53)
Words to Know:
Lift- The force that is opposite the weight of an airplane and holds the airplane in the air. Drag – Air pushing back on the plane as it moves forward. Thrust – What makes the airplane move forward. This can be a propeller, a jet engine, or your throwing arm. Gravity – The force that pulls objects back to the earth. Aerodynamics – Aero means air and dynamics means motion. Aerodynamics is the study of motion through the air.
All day on Saturday, Nov. 23rd, everyone is invited to check out Central Library’s inaugural LEGO robotics tournament! This is your chance to meet 18 real-life central Indiana FIRST LEGO League and Jr. FIRST LEGO League robotics teams who will be showcasing their research, ideas, and solutions for extreme weather! The morning will highlight Jr. FLL teams presenting natural disaster preparedness and response projects, while the afternoon will feature this year’s exciting robot game challenges which face the FLL teams! Be sure to drop in, experience the fun, share the enthusiasm, and cheer the teams on! Event Details.
There are some things you can just never have enough of…M&Ms…and Legos! Here are some websites & books to keep ideas coming little brick by little brick.
A moving rehabilitation story of a pit bull that was rescued from Michael Vick’s notorious dog-fighting ring describes how he and his kennel mates were saved from being euthanized before he was retrained to be a gentle companion animal and adopted by a loving family.
Many pit bull dogs are raised for dog fighting. It’s a brutal life and can make the dogs mean. In 2005 the famous football player, Michael Vick, was arrested for training fighting dogs. Some of his rescued dogs were puppies. This is the story of one of them. Audie started out as a scared little puppy and through love and hard work he became a loving companion. If you love dog stories, this book is for you.
