What is Matter | Matter Facts for Kids Some substances, like glass and water, allow light to pass through them. These substances are called transparent or see-through. The matter is still there, even though it can be hard to see. Humans are very good at changing matter to make things we can use. Gases Gases Gases such as air are the lightest state of matter. Gases › Solids Solids Solids, such as wood and stone, have a fixed shape that is difficult to change. Solids › Liquids Liquids Liquids such as water can flow freely, changing their shape. Liquids › Some matter is bound up in living creatures, such as animals and plants. Earth is mostly made up of nonliving substances such as rock and metal. Changing states Changing states Matter can come in different forms, or states, such as solids, liquids, and gases. Changing states › Atoms › All matter is made up of tiny, tiny particles called atoms. Atoms › Inside an atom › Atoms can be broken down into even smaller particles. Inside an atom › Molecules › Molecules ›
Physics for Kids: Wave Behavior Science >> Physics for Kids When waves encounter new mediums, barriers, or other waves they can behave in different ways. In physics these behaviors are described using some of the terms below. Reflection The word "reflection" is used in everyday life to describe what we see in a mirror or on the surface of the water. In physics, a reflection is when a wave encounters a new medium that acts as a barrier, causing the wave to return to the original medium. The wave "reflects" off the barrier at an angle that is incident to the angle of the wave hitting the barrier (see below). Refraction Refraction of a wave occurs when a wave changes direction upon moving from one medium to another. One example of refraction is a prism. Diffraction Diffraction occurs when a wave stays in the same medium, but bends around an obstacle. An example of a diffracted wave passing through a small opening. Polarization Polarization is when a wave oscillates in one particular direction. Absorption Interference Activities
What is matter? Introduction to matter Matter is anything, such as a solid, liquid or gas, that has weight (mass) and occupies space. For anything to occupy space, it must have volume. Thinking about it, everything on earth has weight and takes up space, and that means everything on earth is matter. Take a look at this boy blowing bubbles. He is holding a cup with some bubble solution in it. The boy's cup, liquid and the air he is blowing is matter. It is because of their individual properties that they are made up of. But what are their individual properties made up of? Good question. In this lesson, we shall look at the behavior and states of matter — Solids, Liquids and Gases, which are known as the three states of matter.

Is Air Made of Matter? How to Prove It Is air made of matter? You can't see or smell the air, so you may be wondering whether or not it is made of matter. Here is the answer, plus how you can tell prove air (or any other phenomenon) consists of matter. How Can You Tell Air Is Matter? Yes, air is matter. One way is to blow up a balloon with air. The matter in air is what supports the enormous weight of a plane. Also, consider the ways you experience air. If you have access to the equipment, you can weigh air on a scale. Weigh the container again. What Type of Matter Is Air? Air is an example of a gas. A gas is a form of matter that can change its shape and volume. If you analyze air, it consists mostly of nitrogen and oxygen, with smaller amounts of several other gases, including argon, carbon dioxide, and neon. The Amount of Matter Isn't Constant The amount of matter in a sample of air isn't constant from one place to another. Seeing and Tasting Air While you can't see or taste air, this is because it's a gas.
CEMC - Web Resources - Emmy Noether Circles - Mathematics Contests - University of Waterloo Named in honour of the mathematician Emmy Noether, this free online project aims to encourage the participation of both teachers and students at the Grade 5 and 6 level in solving problems for enjoyment and satisfaction. The 'circle' symbolizes an inclusive and collaborative setting, open to a variety of ability levels, wherein mutual support enhances individual investigations. Each Circle is a set of six problems, plus hints, suggestions, and solutions. The problems can be used individually, or as a set, as time permits. While group work is a major focus, most problems are also accessible to students who prefer to work on their own. Information for Teachers Certificate of Merit Certificate of Participation Circles are available in the charts below both as complete sets and divided into problems identified by curriculum strand.
What is Matter? Matter is All Around Us We seldom stop to think about it as we go about our daily lives, but we are matter. Everything we detect in the universe is matter. It's the fundamental building block of everything: you, me and all the life on Earth, the planet we live on, the stars, and galaxies. It's typically defined as anything that has mass and occupies a volume of space. We're made up of atoms and molecules, which are also matter. The definition of matter is anything that has mass and takes up space. However, that definition is reall only extended to normal matter. Normal Matter Normal matter is the matter that we see all around us. Normal matter is luminous, not because it "shines", but because it interacts electromagnetically and gravitationally with other matter and with radiation. Another aspect of normal matter is antimatter. When matter and antimatter collide the annihilate and create pure energy in the form of gamma rays. Dark Matter The exact nature of dark matter is not well known.

Investigating Condensation and the Water Cycle Step-by-step Lesson and Free Printables Most kids are familiar with the terms precipitation, condensation, and evaporation, but very few of them really understand what those words mean. Just ask your students to name three examples of condensation in everyday life and watch their eyes glaze over. Huh?? Most kids understand that precipitation is a fancy word for different forms of water falling from the sky, like rain, snow, and sleet. Condensation is a little harder to grasp. Condensation Investigation Here's a simple investigation that will help your students understand what condensation is, where it comes from, and where it happens in everyday life. Condensation Investigation is designed for students working in teams, but it's a teacher-directed exploration rather than an independent group activity. Advance Preparation Before using the activity with your students, gather the materials described on the Condensation Investigation handout, and try the activity yourself.
Doodle Art Alley - Doodle Art Alley Hot Air, Cold Air Science Activity | Learning 4 Kids One of the most amazing highlights of my trip to Dubai was the opportunity to fly in a hot air balloon with Balloon Adventures Emirates. It was incredible! The hot air balloon ride is the inspiration behind The Hot Air, Cold Air Science Activity. This Hot Air, Cold Air Science Activity is a great experiment to watch the effects of hot air and cold air on a balloon. What you will need? You will need two containers, one filled with hot tap water and the other with ice and cold water. Please do not use boiling hot water for this activity. Let’s Play During the following steps of the activity, provide children with the opportunity to predict, ask questions and discuss ideas. Blow the balloon up to stretch it and help make it more flexible and let the air out.Place the balloon over the mouth of the empty plastic bottle.Stand the bottle in the centre of the container filled with hot water.
