Head into the lab for an in-depth investigation of genetics, the branch of biology focused on heredity and variation in organisms, and DNA, the acid that holds the blueprints for life. See genetic material with your own eyes as you isolate the DNA from a tomato in a test tube. Investigate inheritance and learn how traits are passed down from parents to children. Learn about dominant and recessive genes and play inheritance games to determine how traits will be expressed.
Learn about the biology of reproduction, the components of cells, and how chromosomes are combined and copied. Assemble a model to see the elegant double-stranded helical structure of DNA. Then crack the genetic code and find out how the different parts, called nucleotides, fit together to compose it. Read about how scientists, like geneticist Spencer Wells of the National Geographic Genographic Project, use DNA sequencing to reveal the order of nucleotides in DNA.
Analyze DNA evidence to identify suspects and solve a crime. Learn about the influential scientists, including Mendel, Watson, and Crick, who made breakthrough contributions to this field.
Breed your own bacteria colony to experiment with genetic engineering. Read about how mutation affects genes and how scientists clone plants and animals. The full-color, 48-page manual guides your experiments, like isolating the DNA from a tomato, learning about inheritance and how traits are expressed, building a DNA model, and breeding bacteria to experiment with genetic engineering.
“Where science ends, art begins,” wrote the 19th-century
photographer Charles Nègre. STEM learningscience, technology, engineering, and mathhas become a crucial part of school curriculums, but educators have begun transforming STEM to STEAM in recognition of the power of art and ...
Learn how ancient cities defended against outside invasion
and what the internal competition for land was like with this strategic game. Fortress walls in medieval cities like Carcassonne, France, and Rhodes, Greece, kept invaders at bay, but inside the walls ...
You’ll pass lions, impalas, rhinos, and even a
huge termite mound as you maneuver your rover through this safari traffic jam, inspired by Tanzania’s Serengeti National Park. Draw a card to determine the board set-up, then make your escape one ...
