In this section we will be talking about the basics of acids and bases and how acid-base chemistry is related to chemical equilibrium. We will cover acid and base definitions, pH, acid-base equilibria, acid-base properties of salts, and the pH of salt solutions.
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Students play and record the “Mary Had a Little Lamb” song using …
Students play and record the “Mary Had a Little Lamb” song using musical instruments and analyze the intensity of the sound using free audio editing and recording software. Then they use hollow Styrofoam half-spheres as acoustic mirrors (devices that reflect and focus sound), determine the radius of curvature of the mirror and calculate its focal length. Students place a microphone at the acoustic mirror focal point, re-record their songs, and compare the sound intensity on plot spectrums generated from their recordings both with and without the acoustic mirrors. A worksheet and KWL chart are provided.

Students construct rockets from balloons propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.
Students compare and contrast passive and active transport by playing a game …
Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell membrane. Concentration gradient, sizes, shapes and polarity of molecules determine the method of movement through cell membranes. This activity is associated with the Test your Mettle phase of the legacy cycle.

Selected resources provide three web-based activities to complement science lessons in an issue of Beyond Weather and the Water Cycle. The free, online magazine for Grades K-5 teachers explores the essential principles of climate literacy.
Effective measurement techniques include the concept of measurement uncertainty. Students may make …
Effective measurement techniques include the concept of measurement uncertainty. Students may make erroneous conclusions analyzing data using measurements that do not include the uncertainty of the measurement. In this lab, students determine a density range for a metal and identify the material based on this range.
This is a lab activity that allows students to collect data to …
This is a lab activity that allows students to collect data to practice using effective measurement. While other authors have produced similar labs, this version includes uncertainty analysis consistent with effective measurement technique as presented in the module Measurement and Uncertainty.

The Adaptation series highlights the intersectionality of environmental education, geography, and anthropology. Explore our collection of resources and classroom activities that promote civic action by students to make real connections in their local communities as inspired by the actions in the global examples presented in each episode. These lessons could apply to geography, life science, or environmental science/studies classes, as well as innovation and engineering programs with a human-centered design approach. This Collection features 4 videos and a lesson plan for Grades 6-8, 9-12.
How do the differences in adaptations of African and Asian elephants reflect …
How do the differences in adaptations of African and Asian elephants reflect the habitats in which they live? For grades 4-6 from the Connections to Africa program. It is an activity designed to get students to think critically about problem-solving. This activity is designed to start your students in recognizing themselves as scientists and thinking critically about problem-solving. The goal is to teach concepts through discovery and to encourage using scientific thought processes. As with all lessons provided, please feel free to adapt them according to your students’ abilities. You may find it more successful to lead activities and discussions as a whole group rather than using individual Research Plan sheets. Certain scientific vocabulary may or may not be appropriate for your students’ level of understanding. Take these ideas, make them your own and your students will have a greater chance at success.

This activity first asks the students to study the patterns of bird flight and understand that four main forces affect the flight abilities of a bird. They will study the shape, feather structure, and resulting differences in the pattern of flight. They will then look at several articles that feature newly designed planes and the birds that they are modeled after. The final component of this activity is to watch the Nature documentary, "Raptor Force" which chronicles the flight patterns of birds, how researchers study these animals, and what interests our military and aeronautical engineers about these natural adaptations. This activity serves as an extension to the biomimetics lesson. Although students will not be using this information in the design process for their desert resort, it provides interesting information pertaining to the current use of biomimetics in the field of aviation. Students may extend their design process by using this information to create a means of transportation to and from the resort if they chose to.

Meet Cade, a high school hockey player, and learn how his addiction to nicotine from vaping has had physical and behavioral impacts on his life in this digital video from NOVA. Use this resource to stimulate thinking and questions about the consequences of addiction and provide opportunities for students to make evidence-based claims about the health effects of vaping on teens. [3:59] Support materials are provided.
