This activity engages students in learning about ways to become energy efficient consumers. Students examine how different countries and regions around the world use energy over time, as reflected in night light levels. They then track their own energy use, identify ways to reduce their individual energy consumption, and explore how community choices impact the carbon footprint.

Students will complete this survey that determines their personal and household contributions to atmospheric Carbon dioxide by using information about their previous year's consumption. They will understand that Carbon dioxide is a greenhouse gas produced by the combustion of fossil fuels, and that its production can be minimized by taking personal steps to conserve.

Students learn how forces are used in the creation of art. They come to understand that it is not just bridge and airplane designers who are concerned about how forces interact with objects, but artists as well. As "paper engineers," students create their own mobiles and pop-up books, and identify and use the forces (air currents, gravity, hand movement) acting upon them.

The purpose of this learning video is to show students how to think more freely about math and science problems. Sometimes getting an approximate answer in a much shorter period of time is well worth the time saved. This video explores techniques for making quick, back-of-the-envelope approximations that are not only surprisingly accurate, but are also illuminating for building intuition in understanding science. This video touches upon 10th-grade level Algebra I and first-year high school physics, but the concepts covered (velocity, distance, mass, etc) are basic enough that science-oriented younger students would understand. If desired, teachers may bring in pendula of various lengths, weights to hang, and a stopwatch to measure period. Examples of in- class exercises for between the video segments include: asking students to estimate 29 x 31 without a calculator or paper and pencil; and asking students how close they can get to a black hole without getting sucked in.

This reference list has more than 20 recommended astronomy books for older students and adults. For each title, the publisher and publication date is included, along with author name. The list is divided into three subcategories: General Astronomy and Astrophysics, Light and Telescopes, and Digital Imaging and the 3-D Universe.

This article reprints and links to informational text about the adaptations that allow mammals and fish to survive in polar oceans. Versions are available for students in grades K-1, 2-3 and 4-5. Related science and literacy activities are included.

In this interactive activity from ChemThink, take a closer look at atomic structure, properties, and behaviors.

Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.

This lesson introduces J. J. Thomson's discovery of the electron and E. Rutherford's planetary model of atomic structure. This is the first in a series covering modern atomic theory.

The difference between atomic weight and atomic mass in chemistry, and how it compares to the physics definitions of weight and mass.

This is a short impactful poem about physical matter and humanity with a recording of the voice of the author and a free gif image. It is hosted in the blog of the author, Tony Martin-Woods (Antonio Martínez Arboleda) – Arte & Ideas, Originally published as a self-standing poem in the Book "Goddess Summit The Nation" (2018) https://www.amazon.co.uk/Goddess-Summons-Nation-Tony-Martin-Woods-ebook/dp/B07FCJXBQ1

This video segment adapted from A Science Odyssey takes a look at the scale of the atom and the tremendous amount of space between the electrons and the nucleus. If all this empty space exists in matter, how can any substance be solid?

In this activity, students will explore how the Law of Conservation of Energy (the First Law of Thermodynamics) applies to atoms, as well as the implications of heating or cooling a system. This activity focuses on potential energy and kinetic energy as well as energy conservation. The goal is to apply what is learned to both our human scale world and the world of atoms and molecules.

Both of these lessons are classroom activities that require students to build models that display understanding of atoms and molecules. One lesson is structured while the other is guided.

We use motion detectors and a bowling ball to find relationships velocity, mass, and energy.

In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.

This is a laboratory activity in which students will compare the amount of carbon dioxide in four different sources of gas and determine the carbon dioxide contribution from automobiles. They test ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide from a vinegar/baking soda mixture.

The impact of natural disasters is made vivid in this video segment adapted from NOVA. A small town in Iceland, prepared for recurrent avalanches, is devastated when one takes a new and damaging path.

In this experiment, two chemicals that can be found around the house will be mixed within a plastic baggie, and several chemical changes will be observed.

This lecture/activity on force will further a students' understanding of forces on an object, as well as the difference between a balanced and unbalanced forces.
