A2 Students use models to represent objects, processes, and events from the physical setting, the living environment, and the technological world.
a Represent the features of a real object, event, or process using models including geometric figures, number sequences, graphs, diagrams, sketches, maps, or three-dimensional figures and note ways in which those representations do (and do not) match features of the originals.
b Use fractions and multiples to make comparisons of scale.
B Students plan, conduct, analyze data from and communicate results of in-depth scientific investigations; and they use a systematic process, tools, equipment, and a variety of materials to create a technological design and produce a solution or product to meet a specified need.
B1 Students plan, conduct, analyze data from, and communicate results of investigations, including fair tests.
a Pose investigable questions and seek answers from reliable sources of scientific information and from their own investigations.
b Plan and safely conduct investigations including simple experiments that involve a fair test.
c Use simple equipment, tools, and appropriate metric units of measurement to gather data and extend the senses.
g Present the design problem, process, and design or solution using oral, written, and/or pictorial means of communication.
C Students understand the history and nature of scientific knowledge and technology, the processes of inquiry and technological design, and the impacts science and technology have on society and the environment.
C1 Students describe how scientific investigations result in explanations that are communicated to other scientists.
a Describe how scientists answer questions by developing explanations based on observations, evidence, and knowledge of the natural world.
E Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
E1 Students compare living things based on their behaviors, external features, and environmental needs.
a Describe how living things can be sorted in many ways, depending on which features or behaviors are used to sort them, and apply this understanding to sort living things.
