TEACHER DIALOGUE AND STUDENT ABOUT NOBLE GASS

Gambar
In class during chemistry lesson. Teacher: Assalammualaikum Childs, morning. Student: Waalaikumsalam,morning miss. Teacher: Okay we start today's lesson. Today we will discuss about noble gas. Does anyone know what is noble gas? Shindy: Noble gas is in group VIII A. Teacher: That’s right, other opinions? Waye: The most popular gass miss. Teacher: Do you know   why named the noble gas? Waye: The most glorious gas of all gass miss. Teacher: Almost right, It is noble because these elements are very stable or very difficult to react. Akbar: So is she noble because it is lazy? Does it so pathetic! Teacher: Hahah right, Even the first noble gas found to be named argon which means lazy. Meme: First? Indeed how many noble gases? Whether there is a second, third, and so on? Teacher: Off course, there is 6 noble gass Akbar: Wow, are they siblings to each other? Teacher: Off course. Therefore they are put into a group, the VIII A group, also...

CAUSE AND EFFECTS

Gambar
Science seeks to explain and understand the natural world. Things happen for a reason: there is a cause for every effect. In science, the cause explains why something happens. The effect is the description of what happened. Ask your friend, "What do you think will happen if we leave this Popsicle out in the sun?" Allowing the Popsicle to melt provides an opportunity to talk about the sun's heat and its effect on the ice popsicle. During the winter, do the same thing with small cups of water. "What caused our water to turn into ice?" Keep track of the plants in your yard. As you observe a plant thriving and growing, ask your child why. Is the plant receiving good light and water? If the leaves on a plant are drooping, ask your child what could be causing the droopy leaves. Does the plant need more sun? More water? What effect could a new location and some water have on the plant? In this article I will discuss the cause and effect, and I will g...

40 VOCABULARY OF CHEMISTRY

Gambar
Acid  – a compound that, when dissolved in water, gives a pH of less than 7.0 or a compound that donates a hydrogen ion. Atom  – a chemical element in its smallest form, and is made up of neutrons and protons within the nucleus and electrons circling the nucleus. Base  – a substance that accepts a proton and has a high pH; a common example is sodium hydroxide (NaOH). Base anhydride  – oxides of group I and II metal elements. Catalyst  – a chemical (element or compound) used to speed up a reaction, but is regenerated at the end of the reaction. Chemical reaction  – the change of one or more substances into another or multiple substances. Diatomic -consistent of two atoms. Electrolyte  – a solution that conducts a certain amount of current and can be split categorically as weak and strong electrolytes. Electromagnetic radiation  – a type of wave that can go through vacuums as well as material and classified as a self-propagating wave. Fr...

COMPARE AND CONTRAST

Gambar
This handout will help you first to determine whether a particular assignment is asking for comparison/contrast and then to generate a list of similarities and differences, decide which similarities and differences to focus on, and organize your paper so that it will be clear and effective. It will also explain how you can (and why you should) develop a thesis that goes beyond “Thing A and Thing B are similar in many ways but different in others.” In your career as a student, you’ll encounter many different kinds of writing assignments, each with its own requirements. One of the most common is the comparison/contrast essay, in which you focus on the ways in which certain things or ideas—usually two of them—are similar to (this is the comparison) and/or different from (this is the contrast) one another. By assigning such essays, your instructors are encouraging you to make connections between texts or ideas, engage in critical thinking, and go beyond mere description or ...

CLASSIFICATION OF MATTER

Gambar
Matter can be identified by its characteristic inertial and gravitational mass and the space that it occupies. Matter is typically commonly found in three different states: solid, liquid, and gas. A substance is a sample of matter whose physical and chemical properties are the same throughout the sample because the matter has a constant composition. It is common to see substances changing from one state of matter to another. To differentiate the states of matter at least at a particle level, we look at the behavior of the particles within the substance. When substances change state, it is because the spacing between the particles of the substances is changing due to a gain or loss of energy. For example, we all have probably observed that water can exist in three forms with different characteristic ways of behaving: the solid state (ice), liquid state (water), and gaseous state (water vapor and steam). Due to water'...
