How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.

Students explore static electricity by rubbing a simulated balloon on a sweater. As they view the charges in the sweater, balloon, and adjacent wall, they gain an understanding of charge transfer. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments.

Why does a balloon stick to your sweater? Rub a balloon on a sweater, then let go of the balloon and it flies over and sticks to the sweater. View the charges in the sweater, balloons, and the wall.

Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity.

Its purpose is to provide readers with a quick and user-friendly introduction to Open Educational Resources (OER) and some of the key issues to think about when exploring how to use OER most effectively. The second section is a more comprehensive analysis of these issues, presented in the form of a traditional research paper. For those who have a deeper interest in OER, this section will assist with making the case for OER more substantively. The third section is a set of appendices, containing more detailed information about specific areas of relevance to OER. These are aimed at people who are looking for substantive information regarding a specific area of interest. Originally published 2011; Revised 2015.

This training video is part of a series dedicated to helping child welfare workers learn practical skills to cope with the emotional tolls of their very important work. In this video, a meditation specialist goes over basic meditation practices that can be completed in or around the workplace with minimal interruption time.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

Look inside a battery to see how it works. Select the battery voltage and little stick figures move charges from one end of the battery to the other. A voltmeter tells you the resulting battery voltage.

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.

This course is also intended to provide the student with a strong foundation for intermediate algebra and beyond. Upon successful completion of this course, you will be able to: simplify and solve linear equations and expressions including problems with absolute values and applications; solve linear inequalities; find equations of lines; and solve application problems; add, subtract, multiply, and divide various types of polynomials; factor polynomials, and simplify square roots; evaluate, simplify, multiply, divide, add, and subtract rational expressions, and solve basic applications of rational expressions. This free course may be completed online at any time. It has been developed through a partnership with the Washington State Board for Community and Technical Colleges; the Saylor Foundation has modified some WSBCTC materials. (Mathematics 001)

Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.

In this lesson, students hear a story about Brother and Sister Bear, who seem to want everything. The little cubs learn that they must make choices because they cannot have everything they want. Students follow along with the story by completing an activity listing all of the goods that will satisfy the cubs' wants. The students then take part in an activity to construct a word web and graphic organizer (table) to identify goods that will satisfy a want. They will make a choice, identify the problem of scarcity, and recognize their opportunity cost.

This curriculum builds upon many years of educating students in the garden and scales up content across grades and lessons for instructional scaffolding. It is designed as an interactive teaching tool to be co-taught with classroom teachers and garden instructors as leads. Each lesson connects directly to standards: Next Generation Science, Common Core State, Physical Education, and Environmental and Health Education. The concise and easy to-follow lessons are a packed 45 minutes for preschool through fifth grade. Flexibility is important, so some lessons include several activities that teachers can choose from to accommodate their lesson plans. Consistency is also important, so lessons follow themes and structures found in the Curriculum Map. 360 pages.

"Best practice collection for gender balance and non-discrimination in career guidance" was developed in the frame of the Erasmus+ project „Online mentoring and Professional Peer Coaching Skills for Youth Training“. The project brings together the professionals from Romania, Slovenia, Bulgaria, Lithuania and Czech Republic with the aim to focus of the mentoring and career quidance in the field of nursing, teaching and social work of the young persons in search of a job and young professionals.
As their area of nursing, teaching and social work are based on the inter-relationship between the client and the professional, the stereotypes and biases plays crutial role on the both sides. And on the side of professional there exists one challenge on the top: their area of work is strongly connected with the vision of „care“, it´s stereotypes and consequences into the atribution of the female-male division of work. Feminisation of the sector of education and care is evident in every of the involved country – the statistics are used to show the cases in respective countries.
The main theoretical concepts are supported by the relevant statistics from respective partner countries. To underline their relevance to the specific sector of social care, nursing and teaching the specific section (section 4) focus on national statistics. The the question of gender balance has also implication to the labour market as well as for conception of the politics and societal approach to the topic of equality itself. Section 5 determine basic knowledge of the importance of gender balance and it´s benefits for the society and organizational lebel.
Finally section 6 brought the attention to the best practices themselves. They are classified according their topic and focus. Firstly there are listed practices of reaching gender balance in nursing/teaching/social work itself. As examples shows, there is not many attention paid to the topic of non-discriminatory career quidance in the monitored areas. In the second part there are listed practices more widelly toutching this phenomena: non-discriminatory
approach and gender balance on employment market and public sphere.
The collection therefore has the role to rise the awareness about this topic not only between the young professionals, but also between the service care providers as employers who plays a significant role on the employment market. While the demographic situation is strongly associated with ageing trends and it´s impacts to the employability, it is necessery to bear in the mind, that it affects in the different ways men and in different ways women.

Better Arguments can help students learn to engage productively across differences and grapple with differing viewpoints. Linked are resources that are applicable to school-based learning activities and after school programs. These include a curriculum, exit ticket exercise and current events exercise.
