Make Crystal Creations" You can make crystal creations as an easy science experiment for kids. Dip decorations and paper sculptures in a crystal solution, and watch them crystallize overnight! What You'll Need: Waterproof table coveringwaterSaucepanSugarPlastic cupsChenille stems (pipe cleaners)StringScissorsPencilsFood coloringIndex cardsEpsom saltsAlumPermanent markersPie pan Step 1: Cover your work surface. Note that an adult needs to help kids throughout this activity. Step 2: Heat a cup of water until it begins to steam. Step 3: Remove the cup from heat, and stir in 2 cups of sugar. Step 4: Mold chenille stems into decorative shapes (star, heart, cat, initials). Step 5: Tie one end of a piece of string to a chenille stem shape and the other end around a pencil. Step 6: Leave the shape overnight, and then remove it from the solution and let dry on a paper towel. Step 7: When dry, the decorations will be covered with shiny crystals. For larger crystals, allow the chenille stem to soak longer in the solution.
NRCF: Filmade experiment Vi vill inspirera till fysiktänkande i vardagen och tona ner föreställningen om att bara experter med tillgång till speciell utrustning kan observera, studera och undersöka de fysikfenomen som finns runt oss. I våra filmade experiment försöker vi därför så långt som möjligt använda enkel materiel som de flesta redan har hemma. De flesta experimenten kan anpassas till barn och ungdomar i olika åldrar. I förskolan och i lägre årskurser fokuserar man på att uppleva, observera och beskriva; för äldre barn och ungdomar kan man införa mer krävande moment som att dokumentera, jämföra och koppla sina observationer till fysikaliska modeller av verkligheten. Du är välkommen att kontakta oss om du har frågor om eller kommentarer till experimenten. Maila oss: Per Beckman och Carina Fasth
Science Experiments for Kids" Science experiments for kids explain everyday mysteries like what causes rain, answer questions about form and function, and simplify concepts like symmetry and capillary action. They're fun, they're fascinating, and they're a great way to spend time indoors on a cold or rainy day. Forget beakers and Bunsen burners, exploding chemicals and complex instructions. Follow the links below to learn how to conduct simple science experiments: Capturing Leaf Vapor Measure water vapor from a leaf to see if leaves breathe. Look-Alike Tests for Salt and Sugar Try some tests to see how these two compounds act differently. Reverse Garden Plant garbage instead of seeds, and find out what biodegradable means. Make Crystal Creations Add a sparkling crystal coat to decorations and paper sculptures. Liquid Density Test Try this test to see if all objects of the same size have the same density. Water on the Move Construct an experiment that will demonstrate how water moves through tiny spaces in fiber. Magnet Making

Home | Practical Physics This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science. Good quality, appropriate physics experiments and investigations are the key to enhanced learning, and clarification and consolidation of theory. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5.

Ellära för högstadiet Strömstyrka Strömmen i en ledning har två delar som samverkar - elektrisk ström och elektrisk spänning. Den elektriska strömmen kan sägas vara den laddningsmängd som förflyttar sig i ledningen under en viss tid, dvs. den mängd elektroner som rör sig i ledningen. Elektrisk ström betecknas med stort I och dess enhet är ampere som betecknas med ett stort A. Spänning Den kraft som skjuter på elektronerna i den elektriska ledningen kallas för spänning. Motstånd - resistans När elektrisk ström går genom en ledning inser man att det finns ett motstånd i ledningen. Många material leder inte ström alls. Ett material som leder ström halvbra kallas halvledare ex grafit dvs. kol. En vanlig glödlampa har en metalltråd av volfram. En tjock och kort metalltråd leder ström bättre än en lång och smal. Örstedt, Colladon, Faraday Örstedt upptäckte fenomenet elektromagnetism. William Sturgeon förfinade tekniken och skapade en elektromagnet genom att vira metalltråd runt ett järnföremål.
