Texas Essential Knowledge and Skills

7th Grade Science
7.10(A) observe and describe how different environments, including microhabitats in schoolyards and biomes, support different varieties of organisms
(B) describe how biodiversity contributes to the sustainability of an ecosystem

7.11 examine organisms or their structures such as insects or leaves and use dichotomous keys for identification
(B) explain variation within a population or species by comparing external features, behaviors, or physiology of organisms that enhance their survival such as migration, hibernation, or storage of food in a bulb
7.13(B) describe and relate responses in organisms that may result from internal stimuli such as wilting in plants and fever or vomiting in animals that allow them to maintain balance.

Biology
2(E)plan and implement descriptive, comparative, and experimental investigations, including asking questions, formulating testable hypotheses, and selecting equipment and technology;
(F) collect and organize qualitative and quantitative data and make measurements with accuracy and precision using tools such as data-collecting probes, standard laboratory glassware, microscopes, various prepared slides, stereoscopes, metric rulers, balances, gel electrophoresis apparatuses, micropipettes, hand lenses, Celsius thermometers, hot plates, lab notebooks or journals, timing devices, Petri dishes, lab incubators, dissection equipment, meter sticks, and models, diagrams, or samples of biological specimens or structures;
(G) analyze, evaluate, make inferences, and predict trends from data

3(A) analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, so as to encourage critical thinking by the student
(C) draw inferences based on data related to promotional materials for products and services

12(E) describe how environmental change can impact ecosystem stability

Environmental Systems
4(B) assess the role of native plants and animals within a local ecosystem and compare them to plants and animals in ecosystems within four other biomes
(G) predict how species extinction may alter the food chain and affect existing populations in an ecosystem
(H) research and explain the causes of species diversity and predict changes that may occur in an ecosystem if species and genetic diversity is increased or reduced.

7(D) analyze and make predictions about the impact on populations of geographic locales due to diseases, birth and death rates, urbanization, and natural events such as migration and seasonal changes
8(B) explain how regional changes in the environment may have a global effect
(E) analyze the impact of temperature inversions on global warming, ice cap, and glacial melting, and changes in ocean currents and surface temperatures

9(D) describe the effect of pollution on global warming, glacial and ice cap melting, greenhouse effect, ozone layer, and aquatic viability (H) analyze and evaluate different views on the existence of global warming

Earth and Space
Strand 6(C) Relevance. The interacting components of Earth's system change by both natural and human-influenced processes. Natural processes include hazards such as flooding, earthquakes, volcanoes, hurricanes, meteorite impacts, and climate change. Some human-influenced processes such as pollution and nonsustainable use of Earth's natural resources may damage Earth's system. Examples include climate change, soil erosion, air and water pollution, and biodiversity loss. The time scale of these changes and their impact on human society must be understood to make wise decisions concerning the use of the land, water, air, and natural resources. Proper stewardship of Earth will prevent unnecessary degradation and destruction of Earth's subsystems and diminish detrimental impacts to individuals and society.
