What are the Basic Parts of the Atom - Protons, Neutrons, Electrons, Nucleus - This video describes the basic parts of the atom, including the proton, neutron and electron. The electrons are found in the electron cloud. This area takes up most of the space of the atom. The small and dense nucleus hold the protons and the neutrons. The protons and neutrons are measured by amu's, atomic mass units.

Students hypothesize whether vinegar and ammonia-based glass cleaner are acids or bases. They create designs on index cards using these substances as invisible inks. After the index cards have dried, they apply red cabbage juice as an indicator to reveal the designs.

Students learn the basics of acid/base chemistry in a fun, interactive way by studying instances of acid/base chemistry found in popular films such as Harry Potter and the Prisoner of Azkaban and National Treasure. Students learn what acids, bases and indicators are and how they can be used, including invisible ink. They also learn how engineers use acids and bases every day to better our quality of life. Students' interest is piqued by the use of popular culture in the classroom.

This webinar will give you a refresher on top notch lesson planning criteria that we all know to be effective…except with a twist! The twist is sharing tips and tricks for doing this in an online environment! The tips are tricks will include how to:

-engage online learners
-create navigational patters and repeated routines for our learners
-connect with our students and families
-provide timely and meaningful feedback
-deliver content clearly and effectively
-activate prior knowledge
-apply new knowledge to their personal lives

Most of all, we will share templates, strategies, online tools to help us all create fun and engaging learning experiences for us all!

We have a lot of water on Earth, but we also can't actually drink much of it... or use it for farming. That's because most of the water on Earth is saltwater. We humans, like a lot of living things, need freshwater to survive. In this episode of Crash Course Kids, Sabrina talks about the difference between freshwater and saltwater and why freshwater is so important.

In the master-equation formalism, a set of differential equations describe the time-evolution of the probability distribution of an ensemble of systems. This can be used, for example, to describe the varied mRNA copy numbers found in individual cells in a population.

The stochastic simulation algorithm (SSA, Kinetic Monte Carlo, Gillespie algorithm) produces an example trajectory for a particular member of a probabilistic ensemble by looping over the following steps. The current state of the system is used to determine the likelihood of each possible chemical reaction in relative comparison to the likelihoods for the other possible reactions, as well as to determine when the next reaction is expected. Pseudo-random numbers are drawn to "roll the dice" to determine exactly when the next reaction will proceed, and which kind of reaction it will happen to be.

This art history video discussion looks at the Mosaics of Santa Prassede, Rome, early 9th century Mosaics from the early 9th century, under Pope Paschal. The church is dedicated to Saint Praxedes and her sister Saint Pudentiana, daughters of Saint Pudens. The sisters were martyred because they provided Christian burials for martyrs, against Roman law.

This task involves a fairly straightforward decaying exponential. Filling out the table and developing the general formula is complicated only by the need to work with a fraction that requires decisions about rounding and precision.

This task describes two linear functions using two different representations. To draw conclusions about the quantities, students have to find a common way of describing them. We have presented three solutions (1) Finding equations for both functions. (2) Using tables of values. (3) Using graphs.

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.
