Proving an Ecosystem’s Health Through Succession
Students engage in viewing day three of ecosystem changes in lab groups to determine if the ecosystem is healthy or unhealthy based on scientific data and factors.
Communication in Space
Students will work in cooperative groups to create an accurate arrangement of mirrors that work together to relay a laser beam from a Mars space station to Earth’s Mission Control, which will model utilizing satellites in space for communication, an accommodation necessary for manned space exploration.
Mendelian Genetics Using Monohybrids
Students will work collaboratively through a fictitious, real-world scenario to determine the probability of each breeding pair of dogs producing offspring with the desired trait for a fictitious client.
Types of Science Investigations
Students will distinguish between descriptive, comparative, and experimental investigations.
Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.
Stages of Ecological Succession
Students will collaborate on a electronic slideshow presentation and observe, record, and describe the role of ecological succession including both primary and secondary succession.
Modeling the Path of Digestion
Students model the path of digestion using household items.
Producing Plump Produce
In collaborative groups, the students investigate the transport of water within potato cells placed in various tonicity solutions.
In this lesson, students will investigate how gene expression is a regulated process controlled by DNA and the interpretations of codons through translation.
Building a Watershed
Students will model the effects of human activity on watersheds.
Plant, Parts, and Function
Students use prior knowledge of body systems as they make connections to systems in plants. Students learn that some plant systems have similar functions as the respective animal systems. The lesson highlights the following systems in plants: root system, shoot system, vascular system, and reproductive system.
Given laboratory investigation scenarios, students will distinguish between scientific hypotheses and scientific theories.
Given field and laboratory scenarios and laboratory data, students will construct data tables and graphs, using repeated trials and means to organize data.
Conclusions and Scientific Explanations
Given laboratory investigation data, students will determine the best conclusion based upon that data.
Given investigation quantitative data, students will determine its degree of precision and/or accuracy and causes for uncertainties in measured data.
Given examples, students will recognize the importance of taxonomy to the scientific community.
Taxonomy: Major Groups
Given illustrations or descriptions, students will determine the classification of organisms into domains and kingdoms.
Homeostasis: Ecological Systems
Given images, videos, or scenarios, identify and describe the responses of organisms, populations, and communities to various changes in their external environment.
Biological Systems: Homeostasis
Identify and describe internal feedback mechanisms involved in maintaining homeostasis given scenarios, illustrations, or descriptions.
Relationships Between Organisms: Food Chains, Webs, and Pyramids
Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.
