This activity explores the sense of sight, nutritional needs, and the importance of milk and dairy in our diet. Can you think of another toy that pops like a bubble? They calculate molality, boiling points, freezing points, and mole fractions in... Cohesion, adhesion, polarity, and the properties of water are all explored with a fun set of activities. Scientists answered this question in 2005 with the help of physics and math. Why is water so versatile? Some insects breathe air yet live underwater. This worksheet has 7 problems to solve. When water transitions from a column into droplets, the same volume of water has a smaller surface area and therefore requires less energy. In this properties activity, students review the properties of solutions, explain different physical properties, define hydrogen bonding. You could use this sheet to review as a class, or for independent or group study. They explain the different stages in the water cycle. What is it doing? Use different liquids; Experiment with different substances in the water (black pepper, for example, gives a great demonstration of soap deterring germs; Utilize different shapes (talk about velocity and physics) ), (Show the class a photograph of falling water, such as Figure 1, and one or more of the high-speed camera videos of inkjet printers posted on youtube by user imagexpertinc, at: https://www.youtube.com/user/imagexpertinc. Exploring Surface Tension Science4Us case study Right after adopting Science4Us, the pricipal at Cypress Elementary School in Broward County Public Schools in Florida could see that it was a program that would help her students get an important early start in science to help prepare them for later grades. A bigger “boat”? This also happens to ink ejected from the nozzles of inkjet printers. The video instructor demonstrates how to use electromagnetic induction to power a miniature train. Create jumbo bubbles and use them to teach about surface tension or interference, perfect for a physical science lesson on light or molecular attraction. It introduces physics participants to the behavior and characteristics of liquids, buoyant force, Archimedes' and Pascal's principles, and the amazing properties of water.... Students explore water, molecules, and surface tension. Determination is made on why the myriad of biota that interacts at the air-water interface are vital components of aquatic and marine ecosystems.... Students do a series of three experiments. As a stream of water, falls, it transitions from a column of water to spherical droplets. Attraction and repulsion between electric charges at the atomic scale explain the structure, properties, and transformations of matter, as well as the contact forces between material objects. Here is an exciting, and meaningful science lesson on the formation of bubbles! Pairs and individuals get the facts on water's peculiar properties, why living... Raindrops are more like pancakes than teardrops. In this physics lesson, students calculate their percent error using a mathematical formula. Thanks for your feedback! Knowledge gained from other fields of study has a direct effect on the development of technological products and systems. Students determine the magnitude of torque and angular acceleration of a system. The presentation covers states of matter, phase changes, density, pressure Pascal's Principle, buoyant force, Archimedes' Principle, Bernoulli's Principle,... Five fabulous procedures introduce physics or chemistry classes to special properties of matter. Students will interpret a seismograph read-out from an earthquake. Activity, High School
