STEMulating Design Challenges in Science, Grades K–2
Texas Essential Knowledge and Skills (TEKS)
for Science Connections
English Language Proficiency Standards
(ELPS)
3(E) Cross-curricular second language acquisition/speaking. The student is expected to share information in cooperative learning interactions.
2(4) Scientific investigation and reasoning. The student uses age-appropriate tools and models to investigate the natural world.
(B) The student is expected to measure and compare
organisms and objects.
grade grade
Science Concepts
2(5) Matter and energy. The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used.
(A) The student is expected to classify matter by physical
properties, including relative temperature, texture, flexibility,
and whether material is a solid or liquid;
(C) The student is expected to demonstrate that things can
be done to materials such as cutting, folding, sanding, and
melting to change their physical properties; and
(D) The student is expected to combine materials that
when put together can do things that they cannot do by
themselves such as building a tower or a bridge and justify
the selection of those materials based on their physical
properties.
Science Process Skills
2(2) Scientific investigation and reasoning. The student develops abilities necessary to do scientific inquiry in classroom and outdoor investigations.
(E) The student is expected to communicate observations
and justify explanations using student-generated data from
simple descriptive investigations; and
(F) The student is expected to compare results of
investigations with what students and scientists know
about the world.
