It allows you to easily copy the cached video files into another folder for playing/watching them in the future. It automatically scans the entire cache of Internet Explorer, Mozilla-based Web browsers (Including Firefox), Opera, and Chrome, and then findsĪll video files that are currently stored in it. If the video file is stored in your browser's cache, this utility can help you to extract the video file from the cache and save it for watching it in the future. ![]() WebVideoCap - Capture Flash video (.flv) and RTSP/MMS streams from Video Web sitesĪfter watching a video in a Web site, you may want to save the video file into your local disk for playing it offline in the future.InstalledCodec - Displays the list of all Codec drivers currently installed on your system, and allows to disable unwanted Codec drivers.Replay Capture Suite - Capture any video/audio stream and convert it to to 36 popular formats.Note: Flexible plastic soda bottles work better than disposable water bottles because water bottles are often not very flexible and tend to crush completely when squeezed. Flexible plastic soda bottle (18-20 oz.) with cap.Materials Materials for the Demonstration All other common household or classroom materials can be saved or disposed of in the usual manner. Save the bottles and sand for future use. Remind students to wash their hands after completing the activities. Make sure you and your students wear properly fitting safety glasses or goggles. The activity sheet will serve as the Evaluate component of the 5-E lesson plan. Print the student activity sheet and distribute one per student when specified in the activity. Finally, students make an argument that even though a mound of shaving cream keeps its shape, it is not a solid, and that even though sand takes the shape of its container, it is not a liquid.Students watch a short animation that illustrates the incredibly tiny size of atoms and molecules.Students also try to squeeze a bottle filled with water to develop a model of the particles of a liquid.Students squeeze a flexible plastic bottle with a balloon on top of the bottle to develop a model of the particles of a gas.Students observe a solid metal hammer and a nail and view a molecular model animation of the particles in a solid.Students are introduced to the idea that matter is made up of tiny particles called atoms and molecules.NGSS 5-PS1-1: Develop a model to describe that matter is made of particles too small to be seen.The particles don’t interact with one another but just hit and bounce off of each other when they collide. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. In a gas, the particles have very little attraction to each other.The particles of a liquid are close together, always moving, and can slide past one another. ![]() In a liquid, the particles are attracted to each other but not as much as they are in a solid.They are close together and vibrate in position but don’t move past one another. In a solid, the particles are very attracted to each other.Solids, liquids, and gases are made of tiny particles called atoms and molecules.Matter on Earth is in the form of solid, liquid, or gas.Finally, students will use their models of solids, liquids, and gases to explain their observations in the lesson. Students will use the model to describe the differences in attraction among the particles of a solid, liquid, and gas. Students will develop a model to describe that matter is made up of tiny particles, too small to be seen. ![]()
