The main objective of this activity is to illustrate the variation that results from crossing-over during prophase I of meiosis. Other sources of variation from generation to generation are: (1) independent assortment (223 possible...

Tenth graders investigate about mitosis, meiosis, and cell differentiation and their purposes and implications in the development and functioning of multicellular organisms. Students use individual journals and a variety of hands-on...

Young scholars describe the spread and occurrence of HIV/AIDS at multiple scales. They explain global and regional variations in the occurrence of HIV/AIDS and the spread of HIV/AIDS in the United States

Students investigate the concept of evolution and how natural selection is used as an indicator that evolution has happened. They recognize the three effects it has on diversity and how adaptations can develop. Diversity is explained as...

Young scholars view vinegar eels under a microscope at different magnifications. They use a DigiScope with the camera attachment in place of the eyepiece. Students count the number of thrashing movements in 10 seconds. They repeat this...

Students explore the concept of recycling. In this environmental stewardship lesson, students discover how to recycle and compost. Students complete an activity that requires them to sort recyclable items.

Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.

Students determine the differences between reusable, compostable and recyclable trash.

Young foresters examine the strategies, like prescribed burns and thinning, that are employed to ensure healthy forests.

Nearly all students have seen pregnant women and may have questions about human development. Intended for secondary students with mild to moderate mental disabilities, this lesson defines the process of pregnancy  in a...

Students identify the female pelvic organs, understand the changes that occur during puberty, and learn what specific organs are involved in these changes. In this biology lesson plan, students learn the path of the human egg cell during...

Students consider that ammonium nitrate is used as a fertilizer and an explosive. They study the chemistry of ammonium nitrate and consider the advantages and disadvantages of this compound. The dual nature of Ammonium Nitrate was...

Young scholars investigate the effects of pollution on marine ecosystems. They read and discuss an article, identify the effects of pollution on marine life, conduct research on local nutrient pollution, and conduct local water quality...

Students participate in an activity in which they investigate the scientific method and seed germination as well as practice graphing and metric measuring skills. Students examine toxicity by exposing Wisconsin Fast Plants seeds to toxic...

Students study genetic traits using popsicle sticks as chromosomes. In this biology lesson plan, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.

Students study non-point source pollution. They research the concept of bio-degradation and/or Nutrients/Fertilizers and discuss how non-point source pollution impacts the environment. Afterwards, they participate in an interactive...

Young scholars view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.

Pupils discover the concept of decomposition. They examine how it makes the soil more fertile and how it helps plants. They put a compost bin in their backyard and record their observations.

Take an amphibious journey with budding readers as you explore vocabulary in Wendy Pfeffer's informative book From Tadpole to Frog. This text is the backdrop of a vocabulary exercise based on six words: fertilize,...

After viewing information about different types of isolation, students will see that reproduction among a group will cause the frequency of a specific trait to increase. The history of prominent scientists such as Charles Darwin are and...

Did she cheat on her husband? Did the hospital switch the babies? Should they have children? As much as this sounds like the plot for a soap opera, all of these questions fit into a single lesson on genetics. Scholars read about three...

Learners recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Have your young scientists questioned why plants grow a particular way? Through this learning opportunity, scientists gain firsthand knowledge about how plants develop and various factors that affect rates of growth as they bring plants...

Seventh graders describe how the traits of an organism are passed from generation to generation. They distinguish between asexual and sexul reproduction. Students identify traits through genes and those resulting from interactions with...
