Since the Teenage Mutant Ninja Turtles (TMNT) first appeared in a comic book back in 1984, the characters have appeared on everything from lunch boxes to shirts to backpacks. If your child loves turtles, a backpack with TMNT may be the easiest to find in stores and online. However, there are a few other options for turtle-inspired backpacks, including making your own turtle inspired fashions. Turtle shell backpacks look like the shell of a turtle and sit on the back of the wearer. TMNT backpacks can be found in some national retail chains like Target. TMNT shell-shaped backpacks are also available at Hot Topic stores, both the brick and mortar stores and their online shopping site. Of course, there are several online sources for these backpacks as well. Here are a few styles modeled after the TMNT characters. Teenage Mutant Ninja Turtles enjoyed extreme popularity in the 1980s, waned a bit in the 90s, but have recently made a comeback in popularity. You can also find backpacks featuring the four TMNT characters: Leonardo, Michelangelo, Raphael and Donatello.

If your child doesn't care for the ninja turtles, or you simply want something less commercial, there are a few other options on the market. The following backpacks feature turtle shell designs that your child might appreciate:fbu backpack If none of the backpacks listed quite meet your needs, another option is to make your own backpack. backpack leihenFollow the steps below to create a backpack featuring turtle shells:unlimited backpack kingdoms of amalur If you are mechanically inclined or a master seamstress, you might gain inspiration from ideas like designer Davidi Galid's Meiosis backpack that resembles the shell of a turtle. gewa backpack straps

Whether you decide to create a backpack of your own or buy one of the backpacks already on the market, the fun and whimsy of a turtle shell design will capture attention wherever you go. coqenpate backpackThese designs are perfect for back to school backpacks or day trips around town.ogio - bandit ii laptop backpack - blackCreate multiple offspring and record results to explore how meiosis can influence appearance. An up-close view of meiosis. Students can see the chromosomes separate. Learn how meiosis and fertilization shuffle the alleles that offspring inherit. WARNING: Your data will not be saved.

Gametes have only one set of chromosomes. Therefore, meiosis involves a reduction in the amount of genetic material. Each gamete has only half the chromosomes of the original germ cell. Explore meiosis with a computer model of dragons. Run meiosis, inspect the chromosomes, then choose gametes to fertilize. Predict the results of the dragon offspring and try to make a dragon without legs. Learn why all siblings do not look alike. SubjectBiologyFocus AreaModeling and SimulationGrade LevelMiddle SchoolLicenseCC BY 4.0 AAAS Benchmark Alignments (2008) 5. The Living Environment 5A. Diversity of Life 5A/H1a. By the end of the 12th grade, students should know that the variation of organisms within a species increases the likelihood that at least some members of the species will survive under changed environmental conditions.

By the end of the 12th grade, students should know that a great diversity of species increases the chance that at least some living things will survive in the face of large changes in the environment. By the end of the 8th grade, students should know that in organisms that have two sexes, typically half of the genes come from each parent. By the end of the 8th grade, students should know that in sexual reproduction, a single specialized cell from a female merges with a specialized cell from a male. By the end of the 12th grade, students should know that some new gene combinations make little difference, some can produce organisms with new and perhaps enhanced capabilities, and some can be deleterious. By the end of the 12th grade, students should know that the sorting and recombination of genes in sexual reproduction results in a great variety of possible gene combinations in the offspring of any two parents. By the end of the 12th grade, students should know that before a cell divides, the instructions are duplicated so that each of the two new cells gets all the necessary information for carrying on.

5F. Evolution of Life 5F/M1. By the end of the 8th grade, students should know that small differences between parents and offspring can accumulate (through selective breeding) in successive generations so that descendants are very different from their ancestors. By the end of the 8th grade, students should know that reproduction is necessary for the survival of any species. By the end of the 12th grade, students should know that chance alone can result in the persistence of some heritable characteristics having no survival or reproductive advantage or disadvantage for the organism. 11. Common Themes 11B. By the end of the 8th grade, students should know that models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study. By the end of the 8th grade, students should know that mathematical models can be displayed on a computer and then modified to see what happens.

By the end of the 8th grade, students should know that a model can sometimes be used to get ideas about how the thing being modeled actually works, but there is no guarantee that these ideas are correct if they are based on the model alone.
