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.
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.
Covalent Bonding: Electron Dot Diagrams
Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).
Producing Plump Produce
In collaborative groups, the students investigate the transport of water within potato cells placed in various tonicity solutions.
Demonstration and Analysis of Dihybrid Crosses
The students will review related vocabulary, watch the teacher model a dihybrid cross, and then perform a dihybrid cross and answer questions about the outcomes with a partner.
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.
Energy Transfer in an Ecosystem
All matter contains energy. Energy can be transferred from one object to another. Energy transformation can occur through the conversion of energy from one form to another. Energy is never created nor destroyed; it is always transferred and/or transformed. Students will demonstrate how energy is transformed and transferred in an ecosystem. To do this, students will create energy pyramids by stacking cups that represent organisms and available amounts of energy. Students will graph and analyze the 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.
Given scenarios, illustrations. or descriptions, the student will compare variations and adaptations of organisms in different ecosystems.
Cell Homeostasis: Osmosis
The focus of this resource is cell homeostasis and, more specifically, osmosis. Students investigate the concept through a virtual lab, recording and analyzing data, creating sketches to represent vocabulary, and discovering the role of aquaporins in water transport through the cell membrane.
What’s Trending with the Elements?
This resource, aligned with Chemistry TEKS (5)(C), provides alternative or additional tier-one learning options for students using the periodic table to identify and explain trends.
Learners compare a variety of prokaryotes and eukaryotes to determine similarities and differences among and between them.
