Students learn about electrical connections, how they work and their pervasiveness in our world. They consider the usefulness of wireless electrical connections for connecting electrical devices. Morse code is introduced as a communication method that takes advantage of on/off states to transmit messages by electrical bursts sent via wires, light or sound. They learn the Morse code rules and translate a few phrases into Morse code. Specifically, they learn about a wireless connection type known as Bluetooth that can be used to control LEGO robots remotely from Android devices, which leads into the associated activity.

Portland Public Schools has developed this unit. Their hope is that ALL K-5 students will be able to access rigorous, standards-aligned science instruction that engages them in hands-on experiences and sense-making through student discourse. They want to encourage all students to be critical thinkers and lifelong learners. To that end, the science and ESL departments at Portland Public Schools, in consultation with NGSS writer Rita Januszyk, have developed units that are aligned with both Next Generation Science Standards and Oregon’s English Language Proficiency standards.
In this unit, students investigate how gravity affects a variety of objects. They make and support a claim that the sun is a star and that the brightness of stars is related to their distance from Earth. Students use models to support a claim that the Earth’s movement is responsible for the patterns of movement that we see in the sky.

Students learn how common pop culture references (Harry Potter books) can relate to chemistry. While making and demonstrating their own low-intensity sparklers (muggle-versions of magic wands), students learn and come to appreciate the chemistry involved (reaction rates, Gibb's free energy, process chemistry and metallurgy). The fun part is that all wands are personalized and depend on how well students conduct the lab. Students end the activity with a class duel a face-off between wands of two different chemical compositions. This lab serves as a fun, engaging review for stoichiometry, thermodynamics, redox and kinetics, as well as advanced placement course review.

Student teams use the engineering design process to create a useful product of their choice out of recyclable items and "trash." The class is given a "landfill" of reusable items, such as aluminum cans, cardboard, paper, juice boxes, chip bags, egg cartons, milk cartons, etc., and each group is allowed a limited amount of bonding materials, such as duct tape, hot glue and string. This activity addresses the importance of reuse and encourages students to look at ways they can reuse items they would otherwise throw away.

The study of biomimicry and sustainable design promises great benefits in design applications, offering cost-effective, resourceful, non-polluting avenues for new enterprise. An important final caveat for students to understand is that once copied, species are not expendable. Biomimicry is intended to help people by identifying natural functions from which to pattern human-driven services. Biomimicry was never intended to replace species. Ecosystems remain in critical need of ongoing protection and biodiversity must be preserved for the overall health of the planet. This activity addresses the negative ramifications of species decline. For example, pollinators such as bees are a vital work force in agriculture. They perform an irreplaceable task in ensuring the harvest of most fruit and vegetable crops. In the face of the unexplained colony collapse disorder, we are only now beginning to understand how invaluable these insects are in keeping food costs down and even making the existence of these foods possible for humans.

The relationship between the stress and strain that a particular material displays is known as that particular material's stress–strain curve. It is unique for each material and is found by recording the amount of deformation (strain) at distinct intervals of tensile or compressive loading (stress). These curves reveal many of the properties of a material (including data to establish the Modulus of Elasticity

In Grade 8 Module 1, students expand their basic knowledge of positive integer exponents and prove the Laws of Exponents for any integer exponent. Next, students work with numbers in the form of an integer multiplied by a power of 10 to express how many times as much one is than the other. This leads into an explanation of scientific notation and continued work performing operations on numbers written in this form.

Research shows that engaging students in self-assessment positively impacts language learning, motivation, and learner autonomy. To help World Language Educators accomplish this, the Nebraska Department of Education invited experienced world language teachers across the state to create student-friendly assessments in the form of can-do statements in the summer of 2023. This document is a student-friendly self-assessment activity for Advanced Low world language learners created based on the 2019 Nebraska World Language Standards. The language use described in all can-do statements is meant for the target language, except for the second for standard 3.1 and the first for standard 4.2. It is recommended that world language teachers engage students with this document three times in an academic year: pre-course, mid-course, and post-course. Engaging students with this self-assessment activity will help students see growth over time and hopefully attribute growth to effective learning practices. Please feel free to contact chrystal.liu@nebraska.gov for any questions or concerns.

The precursors to what we study today as Trigonometry had their origin in ancient Mesopotamia, Greece and India. These cultures used the concepts of angles and lengths as an aid to understanding the movements of the heavenly bodies in the night sky. Ancient trigonometry typically used angles and triangles that were embedded in circles so that many of the calculations used were based on the lengths of chords within a circle. The relationships between the lengths of the chords and other lines drawn within a circle and the measure of the corresponding central angle represent the foundation of trigonometry - the relationship between angles and distances.

This multi-week project begins with a measurement of baseline consumptive behavior followed by three weeks of working to reduce the use of water, energy, high-impact foods, and other materials. The assignment uses an Excel spreadsheet that calculates direct energy and water use as well as indirect CO2 and water use associated with food consumption. After completing the project, students understand that they do indeed play a role in the big picture. They also learn that making small changes to their lifestyles is not difficult and they can easily reduce their personal impact on the environment.
