The Six Types of Chemical Reaction All chemical reactions can be placed into one of six categories. Here they are, in no particular order: 1) Combustion: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. 2) Synthesis: A synthesis reaction is when two or more simple compounds combine to form a more complicated one. One example of a synthesis reaction is the combination of iron and sulfur to form iron (II) sulfide: 8 Fe + S8 ---> 8 3) Decomposition: A decomposition reaction is the opposite of a synthesis reaction - a complex molecule breaks down to make simpler ones. One example of a decomposition reaction is the electrolysis of water to make oxygen and hydrogen gas: 4) Single displacement: This is when one element trades places with another element in a compound. One example of a single displacement reaction is when magnesium replaces hydrogen in water to make magnesium hydroxide and hydrogen gas:
Make a Bouncing Polymer Ball - Experiment with Polymers Introduction Balls have been toys practically forever, but the bouncing ball is a more recent innovation. Bouncing balls were originally made of natural rubber, though now bouncing balls can be made of plastics and other polymers or even treated leather. You can use chemistry to make your own bouncing ball. The bouncing ball in this activity is made from a polymer. Bouncing Polymer Ball Materials Here's a list of materials you need to gather to make bouncing polymer balls: borax (found in the laundry section of the store) cornstarch (found in the baking section of the store) white glue (e.g., Elmer's glue - makes an opaque ball) or blue or clear school glue (makes a translucent ball) warm water food coloring (optional) measuring spoons spoon or craft stick to stir the mixture 2 small plastic cups or other containers for mixing marking pen watch with a second hand metric ruler zip-lock plastic baggie Let's make bouncing polymers balls...

Chemistry is EASY! How do you do Molar Math in Chemistry? Pinto Bean Germination Experiment Ready, set, grow! How long does it take for a bean to get growing? How does a beanstalk grow in the first place? In this experiment, you’ll investigate the growth of pinto beans and see if you can create a stronger bean plant by giving plants the nutrients they need to survive and thrive. Materials Paper towels 5 Clear plastic cups 10 Pinto bean seeds 5 Plant misters Tap water Magnifying glass Permanent marker Wood ash from a fireplace Liquid kelp fertilizer Liquid fish fertilizer 1 tsp. Procedure Place your clear plastic cups on a table. Results After 4 to 5 days, the growing bean seedlings will begin to sprout. Why? Inside a seed, there’s a whole new plant waiting to grow. Plants need water and light to grow. Wood ash is high in potassium, which provides the correct environment for plant metabolism.

Chemistry is EASY! What is the Mole in Chemistry? Build Your Own Lungs Type Life Science Grade 5th – 7th Difficulty of the Project Medium Cost Safety Issues None Approximate Time Required to Complete the Project 10 – 20 minutes Objective Witness the process of how the lungs expand and contract with the help of the diaphragm. Materials and Equipment/Ingredients Balloons(Grocery/Convenience Store) Clear Plastic 1 Liter Soda Bottles (Grocery Store) Tape (Hardware/ Office Supply Store) Rubber Bands (Hardware/ Office Supply Store) Y Shaped Tube Introduction Build your own lungs out of balloons and soda bottles. Terms, Concepts and Questions for Background Research Expand and Contract Pressure P.S.I. Research Questions What causes the balloons to expand? Experimental Procedure Cut the soda bottle’s bottom end so that it has a large circle on the bottom and the spout on the top. Put this balloon on the bottom of the bottle so that it covers the circular opening. To work the model, pull on the bottom balloon and watch as the 2 balloons on the inside of the bottle grow bigger.

Chemistry is EASY! How do you write electron configurations? Là est la question Manipulations Verse un peu de lait dans le bol Ensuite, dépose quelques gouttes de colorant alimentaire sur la surface du lait, mais sans mélanger. Tu peux t'amuser à déposer plusieurs couleurs dans le bol, chacune séparée. Trempe légèrement le bout du manche de la cuillère de bois dans le savon à vaisselle. Explication Au contact du savon à vaisselle, les gouttes de colorant se dispersent rapidement. Le lait renferme beaucoup d'eau.
How to Design, Create, Develop e-Learning Programs that Work | iSpring Blog It has been predicted that the schools of the future have no walls. Peter Drucker, as well as other successful millionaire entrepreneurs predicted this years ago, before the internet became the center of all that it is today. But with the advent of online learning, it is a whole new world. So, while there are still thousands of brick and mortar schools which show no signs of shutting down, gradually the shift of learning is moving toward a virtual world environment where the chalkboard is replaced by a whiteboard, and the teacher is replaced with a software application. Still, the instructor has been and will continue to be an integral and significant part of the educational process, whether the learning occurs between four walls, or in a virtual classroom. Here are some tips when developing a plan in how to design / how to create / how to develop e-Learning: Know your market. The advantages of using iSpring Presenter are clear: happy developers and happy customers. Learn more →
science - Edventures with Kids We are gearing up for some science fun with this week's Discover & Explore linky. I love introducing hands-on science activities to kids so that they can experiment, think and ponder all those wonderful questions they love to ask to stump their parents ;) There are a number of easy ways to learn with science -- many of them arise from the questions the kids have about things they see happening in the world around them. For fun ideas about how to introduce every day science concepts, try a few of these fun ways to teach kids about science. Other questions are more easily answered with a quick experiment like this one on optial illustions. My kids have always been crazy over the optical illusions they see in books and very intrigued in how it's done. Amazing Optical Illusions Xtreme Illusions (National Geographic Kids) An optical illusion is a visual image that can be perceived differently depending on how you look at it. This is a super easy one to do at home -- here's what you'll need:
