This video illustrates conditions under which two infectious diseases - cholera and dengue fever - flourish, and how climate change is likely to exacerbate those conditions. Note: you may need to scroll down the Changing Planet video page to get to this video.

This interactive activity from ChemThink takes a closer look at a covalent bond--how it is formed and how the sharing of two electrons can keep atoms together.

Students will observe and describe the physical properties of water by exploring water at different stations

In this interactive activity from ChemThink, examine the basic properties of matter at an atomic level and consider how various atoms affect the way a substance behaves.

You probably remember the mole from high school chemistry, but do you remember why it is useful to chemists? The goal of the following video is to give the "big picture" of the mole and its applications; information on how to use the mole in calculations can be found in another tutorial. Throughout this course, we will use the term "molecular weight" to refer to the mass of a mole of a substance (for instance, the molecular weight of oxygen (O2) is 32 g/mol). Recent textbooks refer to this as "molar mass" to emphasize (i) that this term refers to the mass, not the weight, of substance, and (ii) that the quantity refers to a mole of a substance, not a single molecule. "Molecular weight" may be less precise, but it remains the term that most practicing chemists use in the laboratory. For this reason, we continue to use "molecular weight" in this course.

The course contents is general knowledge of the system Earth, tools for the 3D geometric representation of geological objects and methods and techniques for the recognition of fundamental minerals and rocks. The Geology 1 course is composed of three parts dedicated to 1) general knowledge of the system Earth, 2) tools for the 3D geometric representation of geological objects and 3) methods and techniques for the recognition of fundamental minerals and rocks.

This survey chemistry course is designed to introduce students to the world of chemistry. In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior. We will apply this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter. Upon successful completion of this course, students will be able to: Define the general term 'chemistry.' Distinguish between the physical and chemical properties of matter. Distinguish between mixtures and pure substances. Describe the arrangement of the periodic table. Perform mathematical operations involving significant figures. Convert measurements into scientific notation. Explain the law of conservation of mass, the law of definite composition, and the law of multiple proportions. Summarize the essential points of Dalton's atomic theory. Define the term 'atom.' Describe electron configurations. Draw Lewis structures for molecules. Name ionic and covalent compounds using the rules for nomenclature of inorganic compounds. Explain the relationship between enthalpy change and a reaction's tendency to occur.

This interactive resource from the Exploratorium calculates your weight on other bodies in our solar system and offers an explanation of mass and weight and the relationship between gravity, mass, and distance.

The Erie Canal, did the end justify the means? The focus of the inquiry is to explore the complex relationship between the construction, use, and ongoing presence of the Erie Canal and the people who interacted with it throughout history.  This inquiry was created by Chris Nemetz of West Holt Public Schools as part of the Nebraska ESUCC Social Studies Special Projects 2024 - Inquiry Design Model (IDM).

This activity includes twelve monthly star charts to identify the stars that are visible in the night sky and that are known to have planets around them. The star maps can be used to find constellations and identify stars with extrasolar planets. (Northern Hemisphere only, naked eye)

A physics assignment that allows students to address real-life concepts of distance and displacement using their knowledge of vectors and their own school schedule.

Students run a simplified computer model to explore how climate conditions can affect caribou, the most abundant grazing animal in the Arctic.

In this lesson students will learn basic concepts about nutrition while also exploring traditional Indigenous food practices. Students will first learn about energy balance: how the human body derives energy and nutrients from food and expends it through daily activities such as exercise. Next, they will review current recommendations for eating and exercise that promote good health. Finally, they will identify plants and animals that are native to Oregon and provided a well-rounded and nutritious diet for Indigenous people since time immemorial.

This video describes the effect of a warming climate on the tundra biome and specifically the impacts of changing climate on the Rocky Mountain Pika, a small mammal that struggles with summer heat.

This video segment adapted from NASA describes the basic characteristics of our star, the Sun.

In this elementary school lesson on catapult design, students will explore the principles of physics and engineering by constructing their own miniature catapults using simple materials. They will learn basic physics principles as they aim to launch objects with accuracy and distance. Through iterative design and testing, students will refine their models, applying critical thinking and problem-solving skills to achieve optimal performance. The lesson culminates in a friendly competition where teams showcase their catapults' capabilities, fostering creativity and collaborative learning.

ESCOLAR aims to offer ALL elementary and middle-school students the opportunity to learn science within an engaging online environment.

This interactive periodic table developed for Teachers' Domain provides detailed information about the chemical properties of elements and illustrates the electron configurations that determine those characteristics.

A short video on how changing climate is impacting the ecosystem and thereby impacting traditional lifestyles of the Athabaskan people of Alaska.

Observarás y compararás diferentes objetos y podrás identificar las diferentes propiedades de la materia.Esta actividad fue creada por Out Teach (out-teach.org), una organización sin fines de lucro que proporciona aprendizaje experiencial al aire libre, con el objetivo de transformar la educación de las ciencias para los estudiantes en comunidades más desatendidas.
