Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters. This simulation is best used with teacher guidance because it presents an analogy of chemical reactions.

Featuring slow-motion footage of insects in flight, this video adapted from NOVA explores the engineering challenge of designing a robotic aerial vehicle that flies like a bug.

This interactive resource adapted from the National Park Service profiles rocky coast environments and describes how various geologic features form.

In this video adapted from the Encyclopedia of Physics Demonstrations, learn how plotting the changes in an object's position on a graph can provide information about the object's motion.

Learn about rotational forces by watching astronaut Jeffrey Williams spin objects onboard the International Space Station in this interactive activity adapted from NASA.

How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.

Astronomer Carl Sagan discusses the possibility of time travel in this audio-enhanced interview from the NOVAWeb site.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

There are many misconceptions about the chemistry concept, “Conservation of Mass”. Thus, the aim of this video lesson is to teach students about the chemical concept of Conservation of Mass through several chemistry experiments. The students will carry out experiments while assisting a fortune teller named Pak Belalang to gain victory for his kingdom. In an effort to help Pak Belalang, students should be able to answer all the questions related to the Conservation of Mass that are posed by an evil witch. In this video, materials such as a box of matches, a closed and open container, a box of panadol soluble tablets (Alka-Seltzer), and weighing scales are needed. At the end of the lesson, students will be able to see that mass is “conserved”. The lesson will take up to 60 minutes to complete.

The Science Core Guides are created to provide guidance for developing effective instruction aligned to the Utah Science with Engineering Education (SEEd) Standards. They are intended to support teachers, administrators, science specialists, instructional coaches, parents, and other stakeholders as they plan instruction at a local level.

The Core Guides are not intended to be read from cover to cover. They are meant as a resource document to be used, when needed, to support teacher professional learning and curriculum decisions. They are not meant to be used by students, and therefore they may not be written in student-friendly language. The Core Guides are meant to inform teachers and leaders as they make science curriculum decisions.

In this issue of the free online magazine Beyond Penguins and Polar Bears, learn about the tools and technologies scientists use to study the land, ice, ocean, atmosphere, and living creatures of the polar regions. Students can also learn about the day-to-day life of a scientist working at the South Pole and plan their own research expedition.

Students will review the parts of a plant and what a plant needs to grow. Then students will plan and execute an experiement to see the effects of EITHER sunlight or water on the growth of plants by planting 2 seeds and watching their growth. Students will document their experiment with photographs that will then be compiled into an Adobe Express split screen video showing the experiment and giving a concluding explanation of their experiment. Photo Attribution: https://www.flickr.com/photos/30478819@N08/48768936053 (CC BY 2.0)

Students will design a method that applies various chemistry techniques to separate a mixture by physical means to simulate how a scientist would mitigate contamination in a stream due to run-off.

This video segment from IdahoPTV's D4K lists, describes and shows examples of the 6 simple machines and how they make work easier.

Everyone loves slime...especially elementary students. This phenomenon is a great introduction into chemical reactions. The properties of the reactants can be compared to the properties of the products to show that a chemical reaction has occurred. In high school the chemistry of polymers and cross-linking can be explored through slime.

In this video segment adapted from NOVA scienceNOW, learn about engineering innovations that could help detect a bridge's structural weaknesses before they become dangerous.

In this video from DragonflyTV, follow the investigation of Isaac and Anjali as they record, measure, and analyze data about how the Sun's position in the sky affects a solar-powered car's speed.

What is a solar eclipse and why are they only visible in some parts of the world? In this video segment adapted from NASA, astronomer Susan Stolovy uses animations to provide an answer to these questions.

This interactive quiz from the NOVA Web site features an array of interesting facts about the nature of sound underwater.
