Plant Responses

Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

Engage young biologists in exploring the mysteries of life with this collection of hands-on activities. Enlisting the help of numerous digital resources, students get an up-close look at the structure of plant and animal cells as they...

Give young biologists a firsthand look at the process of evolution with this engaging student-centered science investigation. Taking advantage of the rapid life cycle of the Wisconsin Fast Plant, this experiment involves students growing...

The activity really comes to life within its intended unit on starting a rain garden. Working in groups, participants research native plants and coordinate them with the conditions in the designated garden area. Give the class access to...

Would astronauts be able to grow their food on the Moon? Teams research plant growth in order to design and build a growth chamber that will function on the lunar surface. They narrow down plant choices based upon their strengths and...

Male deer growing antlers to begin the breeding season is an example of a phenological event. First in a four-part series is an activity requiring individuals to collect phenological data on their campus. Classes discuss phenology, the...

Plants take cues from the environment—change in daylight hours and temperature—to complete their seasonal life cycles. Lesson four in the series of six has classes collect phenology data on plants. After taking initial observations,...

The living environment, from the interior of a cell to the complex relationships among populations, are queried in this final examination. Learners look at air pollution maps, diagrams of cells, population graphs, and drawing of cells....

Being able to absorb the abilities of other life forms may seem like something taken from a superhero movie, but sometimes reality is stranger than fiction. Join the narrator as he takes viewers back billions of years to investigate how...

Explain the defense systems of both plants and animals against pathogens with a biology video. It covers the disruption of the immune system through hypersensitive responses, normal responses, nonspecific immune responses, as well as the...
