Differences: New to 7th grade, students study the comparison of elements and compounds, utilizing chemical symbols and formulas while also learning about aqueous solutions, including solute and solvent descriptions, concentration, dilution, and exploring factors affecting the rate of dissolution in such solutions.

among force, motion, and energy.

In the new TEKS (7), students describe the cause-and-effect relationship between force and motion.

electromagnetic spectrum, including radio telescopes,

microwaves, and x-rays;

NEW

(F) investigate the emission spectra produced by various

atoms and explain the relationship to the

electromagnetic spectrum; and

NEW

(G) describe and predict image formation as a

consequence of reflection from a plane mirror and

refraction through a thin convex lens.

This was not even a part of older version. Also if we have more labs, that will benifit in understanding.

in Bonding section, TEKS 7A, they have added some new TEK as construct an argument to support how periodic trends such as electronegativity can predict bonding between elements. I guess students need to do more analysis and critical thinking.

I noticed the new one focuses more on F=ma and less on S=d/t. It focuses on calculating acceleration based on the mass of the object.

Sadly, moon phases and seasons are moved to 6 grade.

New: more application based learning for electromagnetic spectrum

Seasons and lunar cycle have been removed. The language for stars, HR Diagrams, and galaxies is more specific in 2021.

(A) analyze, evaluate, and critique scientific explanations

and solutions by using empirical evidence, logical

reasoning, and experimental and observational testing,

so as to encourage critical thinking by the student;

These are all new.

Differences: Students will explore human influence on oceans, Earth's transformation evidence, plate tectonics effects, and celestial body properties.

Conclusion: Content from 6th and 8th-grade TEKS has been integrated for alignment.

TEKS that are removed:

Microhabitats, ecological succession, dichotomous keys, variation in populations, adaptations, functions of structures of cells, cell theory, stimuli.

Moved from Biology:

Taxonomic systems

I noticed that 2017 TEKS for the topic 7 (8) (A) was removed from 2021 TEKS.

substances attain the same temperature such as an ice cube melting and radiation was moved from 6th grade.

I also noticed the TEKS for 2021, explain the relationship between temperature and the kinetic energy of the particles within a substance was added.

I also noticed the TEKS for 2021, explain the relationship between temperature and the kinetic energy of the particles within a substance was added.

forces change the speed or direction of an

object's motion. The 2021 requires more explanations and reason via Newton's Law.

I like the move of biotic and abiotic into 6th grade.

The big Cell unit in 7th grade moved to 8th grade. Also, genetics is now a part of 8th grade! And adaptations, focusing on how adaptations help species survive and reproduce. Yay! excited for this switch.
