David shows how LOL diagrams allow us to visually represent what we mean by conservation of energy as well as what we mean by an energy system. Created by David SantoPietro.

Sal graphs elastic potential energy and kinetic energy for a mass on a spring and compares the total energy when with and without dissipative forces (friction).

This course explores statistical modeling and control in manufacturing processes. Topics include the use of experimental design and response surface modeling to understand manufacturing process physics, as well as defect and parametric yield modeling and optimization. Various forms of process control, including statistical process control, run by run and adaptive control, and real-time feedback control, are covered. Application contexts include semiconductor manufacturing, conventional metal and polymer processing, and emerging micro-nano manufacturing processes.

This training provides participants with the skills to recognize factors that will assist them in accurately identifying neglect, emotional abuse and physical abuse as defined by California law.

After attending this training, participants will be able to: Identify factors that constitute abuse and/or neglect as defined by the Welfare & Institutions Code Section 300 (a) - (j) and recognize parenting behaviors that promote child safety and family well-being outcomes; distinguish scenarios of child maltreatment from those that are not child maltreatment based on a constellation of factors such as physical injuries and behavioral indicators, within a cultural context; and value the importance of diversity as it relates to child maltreatment.

Successful participants will be better equipped to recognize conditions contributing to child maltreatment as well as common injuries bringing children to the attention of child welfare.

Students will listen for sounds in the garden paying careful attention to volume (how loud or soft a sound), pitch (how high or low) , or if it is a natural or man- made sound.

Explore forces, energy and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work.

In this activity, learners use the STELLA box modeling software to determine Earth's temperature based on incoming solar radiation and outgoing terrestrial radiation. Starting with a simple black body model, the exercise gradually adds complexity by incorporating albedo, then a 1-layer atmosphere, then a 2-layer atmosphere, and finally a complex atmosphere with latent and sensible heat fluxes. With each step, students compare the modeled surface temperature to Earth's actual surface temperature, thereby providing a check on how well each increasingly complex model captures the physics of the actual system.

This activity is a classroom experiment where students participate or observe that different densities of liquids will yield different results in a sink-or-float activity.

This activity is a classroom investigation where student observe several properties of water; adhesion and cohesion. They will transfer this knowledge to predicting other materials that will have adhesion with water molecules.

Students have a discussion on the different levels of security they would like for personal data. Once the class has developed an understanding of the importance of privacy, they learn about the process of encrypting information by enciphering a note for a partner and deciphering the partner's note. The class concludes with a discussion about the importance of both physical and digital security.

It this exercise the students will discover that pure water does not conduct electricity and that dissolving different substances in water may or may not cause it to conduct electricity.

This investigation will have students testing how heating and cooling can change the state of matter. They will test a variety of materials determine whether a change takes place through heating/cooling.

This is a guided inquiry investigation for students to determine the state of matter of a mystery material and to make potential real world applications/products for the mystery material.

Learn how friction causes a material to heat up and melt. Rub two objects together and they heat up. When one reaches the melting temperature, particles break free as the material melts away.

This suite of short video clips is part of a series produced by the Switch Energy project. There are several video segments that discuss different perspectives of biofuels as a renewable source of energy.

This fuel cell animation demonstrates how a fuel cell uses hydrogen to produce electricity, with only water and heat as byproducts. The animation consists of four parts - an introduction, fuel cell components, chemical process, and fuel cell stack.

This map shows how much electrical power is produced from wind in each state from 1999 through 2010. The animation shows a general increase in the amount of wind power produced per state and the number of states producing it.

STUDENT ACTIVITY -- 5th -- NCThis is a distance-learning lesson students can complete at home.Students will explore the outdoors for natural examples of heat transfer through conduction, convection, and radiation.This activity was created by Out Teach (out-teach.org), a nonprofit providing outdoor experiential learning to transform Science education for students in under-served communities.

This lesson discusses the interior structure of the earth as defined by research on the behavior of seismic waves as they move through the layers inside of the planet. The lesson details both compositional layers as well as mechanical layers.

This is a lesson about using light to identify the composition of an object. Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light sources and make conjectures about the composition of a mystery light source. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.
