Weddell seal project researchers are investigating whether Weddell seal pups that spend more time in the water learning to swim with their mothers have a higher probability of surviving to return and have pups of their own. Weddell moms spend a lot of time with their pups coaxing them into the cold Antarctic water and helping their pups get in and out of the water as they learn to swim. During this time, Weddell pups are also nursing and gaining substantial weight from their mothers' rich milk before they are weaned and left to fend for themselves.

Wisconsin Fast Plants, rapid-cycling brassicas, are part of a large family of plants called crucifers (Latin = Cruciferae). This resource tells the story of Crucifers, which are easilydistinguished by the characteristic shape of their flowersĺŃfour petals in the shape of a cross or crucifix. A section, or genus, of the crucifer family is the genus Brassica.Brassicas have great economic and commercial value, and play a major role in feeding the world population. They range from nutritious vegetables, mustards and oil producing crops, to animal fodders and weeds.

Artists are often particularly keen observers and precise recorders of the physical conditions of the natural world. As a result, paintings can be good resources for learning about ecology. Teachers can use this lesson to examine with students the interrelationship of geography, natural resources, and climate and their effects on daily life. It also addresses the roles students can take in caring for the environment. Students will look at paintings that represent cool temperate, warm temperate, and tropical climates. In this lesson students will: Identify natural resources found in particular geographic areas; Discuss ways in which climate, natural resources, and geography affect daily life; Apply critical-thinking skills to consider the various choices artists have made in their representations of the natural world; Make personal connections to the theme by discussing ways they can be environmental stewards; Identify natural resources found in particular geographic areas; Discuss ways in which climate, natural resources, and geography affect daily life; Apply critical-thinking skills to consider the various choices artists have made in their representations of the natural world; Make personal connections to the theme by discussing ways they can be environmental stewards.

Students are introduced to the concept of engineering biological organisms and studying their growth to be able to identify periods of fast and slow growth. They learn that bacteria are found everywhere, including on the surfaces of our hands. Student groups study three different conditions under which bacteria are found and compare the growth of the individual bacteria from each source. In addition to monitoring the quantity of bacteria from differ conditions, they record the growth of bacteria over time, which is an excellent tool to study binary fission and the reproduction of unicellular organisms.

In this inquiry activity, students generate investigable questions to explore the link between hygiene/cleanliness and bacteria growth/population. The students will present their conclusions, and video clips containing additional information will be discussed.

Students will investigate how much bacteria surrounds them in their daily lives, even though they cannot see it with the naked eye. Students will conduct an experiment to obtain samples from a classroom surface of their choice, both before the surface is cleaned and afterwards. Students will incubate the petri dishes under a heat lamp for a week, and then compare the pre-washed sample with the post-washed sample. Students will try to identify the type of bacteria by using internet or paper bacterial guides, and to find out if their bacteria is helpful, harmful, or benign. Also, students will be reminded of the importance of frequent hand washing, as well as how infections are spread when proper hygiene is not used.

Students construct paper recombinant plasmids to simulate the methods genetic engineers use to create modified bacteria. They learn what role enzymes, DNA and genes play in the modification of organisms. For the particular model they work on, they isolate a mammal insulin gene and combine it with a bacteria's gene sequence (plasmid DNA) for production of the protein insulin.

A rocket is a missile or craft that is propelled by the thrust from a rocket engine. Rocket engines work by action and reaction and propel rockets forward by releasing exhaust in the opposite direction at high velocity. Harnessing the gas from the reaction of baking soda and vinegar, we will build enough carbon dioxide pressure to launch our bottle rockets sky-high. Decorate and innovate your ship before flight. Will it have wings and propellers, or do you prefer stripped-down aerodynamics?
