This site offers engineering challenges with things you have at home. Kids learn from taking items from their everyday life and using them in new ways to do simple things. It helps them understand the world around them and how things work.

This week we are looking at renewable energy sources and why we need them. We’ll explore hydropower, wind, geothermal, and solar power, as well as some of the challenges, and how engineers are working to make their use more widespread.

We’ve talked about many important concepts for engineers, but today we’re going to discuss a hugely important one that you might not even realize is an engineering concept: ethics. We’ll talk about what a Code of Ethics is. We’ll explore engineering ethics and the ethical theories of utilitarianism, rights ethics, and duty ethics. We’ll also take a look at a few different real life examples of ethical problems in engineering.

This awesome science video explores how engineers identify and control variables as they are working on designing a solution to a problem.

This awesome science video outlines the engineering process - a series of steps engineers use to guide them as they solve problems. The steps include:
- define the problem
- do your research
- develop a possible solution
- design your solution
- build a prototype
- test it
- evaluate your solutions

TED Studies, created in collaboration with Wiley, are curated video collections 壽� supplemented by rich educational materials 壽� for students, educators and self-guided learners. In Climate Change, speakers give talks that boldly illuminate the nature and scale of current-day climate science, policy and ethics. They explore the economics and psychology of individual and collective action 壽� or inaction 壽� on climate change in order to assess the costs of our choices and opportunities for change. Relevant areas of interest, study and coursework include: ecology, atmospheric science, oceanography, glaciology, energy development, environmental policy, science in the media, political science, ethics, sociology, behavioral psychology and cultural studies.

After Darwin blew the doors off the scientific community, a lot of people did some weird and unscientific stuff with his ideas. Francis Galton and a few others decided natural selection could be used to make the human race "better" and came up with Eugenics.

Hank tells us about the city of Eukaryopolis - the animal cell that is responsible for all the cool things that happen in our bodies.

A PBS Learning Media resource that is perfect for pre-K kids. Topics from math, science to art provide early childhood resources to strengthen kids’ interest and sense of discovery.

Hank gets real with us in a discussion of evolution - it's a thing, not a debate. Gene distribution changes over time, across successive generations, to give rise to diversity at every level of biological organization.

Hank introduces us to the relatively new field of evolutionary developmental biology, which compares the developmental processes of different organisms to determine their ancestral relationship, and to discover how those processes evolved. Also fruit flies with eyes on their legs and chickens with teeth!

Hank takes us on the fascinating journey through our excretory system to learn how our kidneys make pee.

Immerse yourself with a team of scientists, climbers, and Sherpa guides as they embark on an expedition that will help define our understanding of high-mountain environments. Experience the National Geographic and Rolex Perpetual Planet Everest Expedition, which was not simply a climb of the mountain, but a perilous adventure to learn how climate change is impacting the highest place on Earth.

The Exploratorium isn't just a museum; it's an ongoing exploration of science, art and human perception—a vast collection of online experiences that feed your curiosity.

Explore Learning offers 3 programs to support students learning at home:

Gizmos (Grades 3-12) Get hands-on with math and science.
Gizmos are online simulations that excite curiosity and invite interaction. We’ve got over 400 Gizmos in our library covering topics and concepts in math and science for grades 3-12. Gizmos help students dig deeper into subjects and really understand challenging concepts.

Reflex (Grades 2-6) When they use Reflex, kids love math.
Adaptive and individualized, Reflex is the most effective system for mastering basic math facts in addition, subtraction, multiplication and division.
Full of games that students love, Reflex takes students at every level and helps them quickly gain math fact fluency and confidence. And educators and parents love the powerful reporting that allows them to monitor progress and celebrate success.

Science4Us (Grades K-2) It’s never too early to learn science!
Science4Us covers Inquiry, Physical Science, Life Science and Earth & Space Science with lessons specifically designed for K-2 students. The sessions have 1000’s of online and offline activities that can be completed in as little as ten minutes, and teach students using videos, interaction, poems, songs, and digital notebooks.

Exploring by the Seat of Your Pants brings science, exploration, adventure, and conservation to students through virtual speakers and field trips with leading experts across the globe. All past live streams are available and access is free.

The ocean and atmosphere each react to changes in the other. These reactions and counter-reactions can snowball until the system builds to a point where potentially disastrous effects occur, such as the El Nino events of 1982-83 and 1997-98. This site describes how the Jet Propulsion Laboratory's TOPEX-Poseidon satellite was used to monitor the amount of sea level rise in the Eastern Pacific Ocean, and consequently the amount of heat stored in the water. Sea level and temperature data from TOPEX-Poseidon was used successfully to predict the 1997-98 El Nino event earlier than ever before. It features text, remotely-sensed imagery and a link to JPL's Physical Oceanography website.

In this episode of Crash Course Kids, Sabrina talks about the way energy moves, or flows, through an ecosystem and how that movement forms Food Chains!

Using an Arduino microprocessor, students will build an automated fish food feeder so fish can be fed when no one is at school?

This project involves learning how to do simple wiring of an LED, a buzzer, and a servo (motor) to a simple-to-use Arduino microprocessor.
