In 2001, Budding Blooms Greenhouse was created and initiated for fourth-grade students between two elementary school teachers at Tower Rock Elementary School in Prairie du Sac. The purpose was to create hands-on activities that promote an understanding and respect for Wisconsin’s agriculture. The vision for ls project was three-fold: to-naturally integrate real-world learning in every part of the curriculum, to utilize the program as a mentorship opportunity, and to obtain district-wide involvement.
The principles involved in morphogenesis and the determination of complex cellular patterns …
The principles involved in morphogenesis and the determination of complex cellular patterns are examined using examples from animal systems in which the tools of genetics, molecular biology and cell biology have been applied to reveal mechanism. This graduate and advanced undergraduate level lecture and literature discussion course covers the current understanding of the molecular mechanisms that regulate animal development. Evolutionary mechanisms are emphasized as well as the discussion of relevant diseases. Vertebrate (mouse, chick, frog, fish) and invertebrate (fly, worm) models are covered. Specific topics include formation of early body plan, cell type determination, organogenesis, morphogenesis, stem cells, cloning, and issues in human development.

Considers molecular control of neural specification, formation of neuronal connections, construction of neural systems, and the contributions of experience to shaping brain structure and function. Topics include: neural induction and pattern formation, cell lineage and fate determination, neuronal migration, axon guidance, synapse formation and stabilization, activity-dependent development and critical periods, development of behavior.

As a human embryo develops, its cells become progressively restricted in the types of specialized cells that they can produce. Inner cell mass (ICM) cells of the blastocyst can make any type of body cell. Gastrula-stage cells can give rise to the cells of a given germ layer. Later, cells become even more restricted. For example, the pancreatic bud of the endoderm layer can only make the cells of the pancreas.

In this interactive demonstration students will make observations of diffusion of a semi permeable membrane and be able to compare these observations to the functions of a cell membrane.
This activity demonstrates diffusion, osmosis, and active transport through 12 interactive models. …
This activity demonstrates diffusion, osmosis, and active transport through 12 interactive models. Start by following the path of a molecule of dye in water, create concentration gradients on either side of a cell membrane and watch the movement of substances in and out of a cell, and monitor the movement of oxygen into red blood cells with and without hemoglobin.
Biological membranes are selectively permeable; some molecules can cross while others cannot. …
Biological membranes are selectively permeable; some molecules can cross while others cannot. One way to affect this is through pore size. Change the pore size with the slider to change the permeability of the membrane to the different types of molecules. Trace an individual molecule to see the path it takes.

In a multi-week experiment, student teams gather biogas data from the mini-anaerobic digesters that they build to break down different types of food waste with microbes. Using plastic soda bottles for the mini-anaerobic digesters and gas measurement devices, they compare methane gas production from decomposing hot dogs, diced vs. whole. They monitor and measure the gas production, then graph and analyze the collected data. Students learn how anaerobic digestion can be used to biorecycle waste (food, poop or yard waste) into valuable resources (nutrients, biogas, energy).

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).

This is a field investigation on diversity of life where students count the number of kinds organisms in two locations. Students report their results on posters and propose reasons why there might be difference in diversity between the locations.

Our planet is becoming hot. In fact, Earth may be warming faster than ever before. This warming will challenge society throughout the 21st century. How do we cope with rising seas? How will we prepare for more intense hurricanes? How will we adapt to debilitating droughts and heat waves? Scientists are striving to improve predictions of how the environment will change and how it will impact humans. Earth in the Future: Predicting Climate Change and Its Impacts Over the Next Century is designed to provide the state of the art of climate science, the impact of warming on humans, as well as ways we can adapt. Every student will understand the challenges and opportunities of living in the 21st century.
