Go to the website with animation for electrical circuits: . Download will start automatically (OK answer questions about download and open the file). Use simulation to answer the questions below. How you need to assemble components (parts) to get a light bulb to light? Note: This lamp has several points of contact. What do you think happens if you put several bulbs on one battery? Use voltmeter to measure what a circuit with a light bulb and shows what several light bulbs shows (you measure the light bulb)? Voted result with what you answered the question? What happens if you use two batteries and a light bulb? Gets all the same result? What happens if you have two batteries and two bulbs - is there a difference from having a light bulb and tobatterier? Explain what is happening and why. What do you think happens if you replace a line with one of the products is the surprise package (bank note, paper clips, coins, eraser, pencil, hand and dog)? Write down what you think will happen and examine hypotheses are correct.
Electrical circuits, series and parallel connections, create and explore their own hypotheses through creativity and exploration. It can be made many different types of questions than those suggested above. Note: in the simulation can remove items, right-click and select Remove, and to solve the connection points by right clicking which they are associated. Wires can be shorter or longer by pulling the ends of the wire. The simulation can also be used on electronic tablet.
Relevant links: Refleksjonsark for student website for animation with electrical circuits (alternatively, go to Phet Colorado and look up cicuit Construction Kit - file can be downloaded so that it does not rely on internet connection when it is displayed. Scroll down the animation to find with Norwegian text and select download). Java Extra Tip demonstration: Potato Battery
