So, if gravity pulls everything down, then why don't things on the bottom of the Earth get pulled down into space? In this episode of Crash Course Kids, Sabrina talks about gravity and explains that when we talk about gravity pulling things down, what we really mean is gravity is pulling things TOWARD the Earth. Really, it's all about attraction.

This awesome science video goes over the process of defining success that engineers use when they are solving problems, part of the engineering process.

This awesome science video goes over the hows and whys that engineers consider when they are trying to define a problem, the first step in the engineering process.

Upon completion of the Solids and Liquids unit in Grade 2 Science, students have been exposed to a wide variety of the properties of solids and liquids. In order to address higher levels of thinking, such as evaluation, synthesizing and creating, I used this performance task to allow my students to summarize, show and use what they had learned throughout the unit. This challenge allowed students to creatively build a boat, using common household materials. They then tested its capacity to float and carry a load, assessed its effectiveness and lastly revised and improved it.

This awesome science video explores how engineers go about designing trials to test solutions to problems.

Hank takes us through the bowels of the human digestive system and explains why it's all about surface area.

Let's continue the exploration of the Water Cycle by drinking some dinosaur pee. Yep! Well, it's a little less gross that it sounds. It turns out that all of the water on Earth is just constantly recycled in what we call a closed system. No water comes in and no water goes out. So that means that, at some point, it's possible the water we're drinking was once dinosaur pee... or tears...

We know about food chains and how energy moves through an ecosystem. This video takes a step back to examine everything starts... and ends - with Decomposers!

Classification: DL6.2 Examine how humans organize understanding of the diversity of living things.
Characteristics and Behaviours: DL6.3 Analyze the characteristics and behaviours of vertebrates (i.e., mammals, birds, reptiles, amphibians, and fish) and invertebrates.
Adaptations: DL6.4 Examine and describe structures and behaviours that help individual living organisms survive in their environments in the short term and species of living organisms adapt to their environments in the long term.

Doodles Academy is a powerful free art curriculum for grades 1-5 that is available virtually. It provides art projects that offer authentic art experiences for students -- every student makes their own artistic decisions and walks away from the project with an artwork unique to them. Each project includes video tutorials and thorough lesson plans so that anyone can feel comfortable teaching art, regardless of their background or experience level. More, the art projects are aligned to topics and themes found in literacy, math, social studies, and science, so while students work through an art project they are building knowledge and context around other subjects.

In this episode of Crash Course Kids, Sabrina talks about why things on the bottom of the Earth, don't just fall off into space.

Today we’re talking about mass transfer. It doesn’t just apply to objects and fluids as a whole, but also to the individual molecules and components that make them up. We’ll see that transfers of mass need their own driving force, discuss diffusion, and use Fick’s Law to help us model mass transfer.

This site offers educational for kids in lots of topics, including: history, science, biographies, geography, games and fun.

The official Earth Day website showcases a variety of information surrounding this impactful day. The information includes Projects, Challenges, Videos to provide background information about the our world today and challenges and projects that your classrooms can participate in to make a difference in our world now and for the future. In addition, the website has downloadable ToolKits for your classrooms.

Use these free activities to help kids explore our planet, learn about global challenges, think of solutions, and take action.

This text explores a few of the many concepts that frequently come up in the study of Earth systems and global climate change. Students will be exposed to many problems involving unit conversion. Global climate change reports involve terms such as kilowatt-hour, megawatt-hour, and gigawatt-hour, as well as megatons and gigatons. Students will become versed in converting units where appropriate, and through the calculations, will work with the concept of significant figures. Creating linear equations from graphical and tabular information is covered, as well as forecasting. The text is meant to be used as a companion to standard Earth science and mathematics courses, and presents enough application problems to allow students to quantitatively understand typical media reports about global climate change.

The study of clouds (where they occur, their characteristics, etc) plays a key role in the understanding of climate change. This site discusses how the relative thickness and altitude of various cloud types result in their either reflecting solar radiation or transmitting and trapping it, thereby warming Earth's surface. It features text, a scientific illustration, and links to other relevant topics and datasets.

This Earth Observatory site contains data and images from NASA's Earth Observatory project. The purpose of NASA's Earth Observatory is to provide an accessible publication on the Internet where the public can obtain new satellite imagery and scientific information about our home planet. The focus is on Earth's climate and environmental change. The site is useful to public media and educators. Data and images can be obtained for a variety of subjects, the Earth's atmosphere, land, life on earth, oceans and heat and energy. Users can enter data on a variety of topics and produce animations depicting the data entered. The site also contains a helpful section explaining how to build animations and globe animations.

The Earth Observatory Glossary defines words from space science, ecology and Earth science. It is part of the NASA Earth Observatory site, which provides new satellite imagery and scientific information about Earth with a focus on climate and environmental change. The new glossary mode allows users to browse the Earth Observatory site with special terms highlighted that, when selected, will take you to the appropriate entry in the glossary.

It's Earth Science time!!!! In this field, natural philosophers were asking questions like, what’s up with fossils? Are they the remains of extinct organisms? Or are they so-called “sports of nature”—rocks that just happen to look like living things but don’t /mean/ anything? And most importantly, how old is… everything?
