A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
plan and conduct an investigation to provide evidence that the rate of reaction or dissolving is affected by multiple factors such as particle size, stirring, temperature, and concentration.
investigate how solid and gas solubilities are influenced by temperature using solubility curves and how rates of dissolution are influenced by temperature, agitation, and surface area;
Recurring themes and concepts — Connections to the content
Recurring themes and concepts provide a connective structure for scientific ideas across disciplines. The connection(s) below show some ways that teachers can help students understand how the content they are learning fits into the broader understanding of science. These connections do not represent all possible connections that might be made but highlight some that are appropriate for this grade level.
Patterns
Patterns are regular sequences that can be found throughout nature.
Patterns allow scientists to classify substances as elements, compounds, or mixtures. Elements are always composed of one type of atom. Compounds are always composed of different elements that are chemically bonded together. Mixtures may consist of a variety elements and/or compounds.
Cross-curricular Connections
The cross-curricular connections are designed to help educators make content connections between the science TEKS and math, English language arts and reading, social studies, and technology applications. The standards below illustrate alignment between grade level content areas which may help educators develop cross-curricular lessons. These connections do not represent all possible connections that might be made.
