Esta simulação proporciona uma oportunidade de praticar uma digestão por enzimas de restrição em um cenário de laboratório virtual. As enzimas de restrição são usadas para cortar as cadeias de DNA de dois plasmídeos, produzindo fragmentos de DNA com extremidades complementares coesivas que podem ser remontadas para criar um plasmídeo recombinante.

In this unit, students make regular journal entries about a plant/animal/insect community in the natural area around our school and use this to create a Non-fiction Class Book. They also interview family/resources to discover, record and present stories about human relationships with nature from their culture(s).

Some people may think dung beetles are gross. After all, they live in and eat animal waste! But Dr. Nicole Gunter, the Museum’s Associate Curator of Invertebrate Zoology, finds them utterly fascinating. In fact, they’re her favorite animal. “Why?” you might ask. Get the scoop in this video. Worksheets available for grades 7-8 and 9-12.

Students make edible models of algal cells as a way to tangibly understand the parts of algae that are used to make biofuels. The molecular gastronomy techniques used in this activity blend chemistry, biology and food for a memorable student experience. The models use sodium alginate, which forms a gel matrix when in contact with calcium or moderate acid, to represent the complex-carbohydrate-composed cell walls of algae. Cell walls protect the algal cell contents and can be used to make biofuels, although they are more difficult to use than the starch and oils that accumulate in algal cells. The liquid juice interior of the algal models represents the starch and oils of algae, which are easily converted into biofuels.

This activity demonstrates the effect of changes in the environment on the growth of plants. The plants are placed in environments such as high salinity, cold, heat, or drought and observe the different reactions (growth) of the plants to these conditions. Students discuss the desirability of breeding new types of plants that are better able to withstand these changes if they occur in the general environment. The objectives of this activity is to: 1. Plant, grow and maintain plants under different environmental treatment conditions. 2. Observe differences in plant growth between these treatments. 3. Compare the growth of treated plants with the growth of control plants
