Students complete hands-on activities and read information online in order to answer the central question of the lesson: How does understanding the chemistry of hair care, including the role of pH, help in the development of better hair-care products.
This lesson is partially aligned to standard 7.P.2.3 — Recognize that energy can be transferred from one system to another when two objects push or pull on each other over a distance (work) and electrical circuits require a complete loop through which an electrical current can pass. It focuses primaryily on energy transfer and electrical circuits. It does require some preparation and supplies such as a circuit kit, and holiday lights, wire stripper, allumnimum foil, bracket fasteners and tape. This is an engaging resource and does not utilize technology.
In this unit, students will review Newton's second law and learn how physics can be applied to real world problems. Lessons in this unit include: Newton's Second Law Revisited; Amusement Park Physics; and Athletics. This unit includes animations and mini quizzes to check for understanding and facilitate learning.
Find areas that are predicted to change because of climate change.
GeoInquiries are designed to be fast and easy-to-use instructional resources that incorporate advanced web mapping technology. Each 15-minute activity in a collection is intended to be presented by the instructor from a single computer/projector classroom arrangement. No installation, fees, or logins are necessary to use these materials and software.
My lesson is designed to target standards related to force and motion, and integrating it with computer science. The connection with movements is a practical way to help students understand about how a piece of technology (coding) works. They will learn that real word could be brought into virtual life.
Students will gain a better understanding of what energy is, how it can be changed into other forms of energy, and how physical and chemical processes contribute to that. They also will learn what happens to energy when materials are heated in a combustion system, as in an auto gasoline-powered engine.
Students will enhance their understanding of combustion using the reaction between dry yeast and hydrogen peroxide. The eperiment demonstrates that certain things are needed for combution - especially oxygen.
Students will observe properties and compare water in the 3 states of liquid, solid, and gas. Utilizing a triple Venn diagram to help deepen their understanding of matter.
This lab activity is designed to allow students to experience what an increase in mechanical advantage means. Students determine the mechanical advantage of three pulley set-ups. Students also measure the work input and output, then calculate the efficiency. Finally, students determine the relationship between the mechanical advantage and the efficiency of the pulleys.
Through this activity students will understand that there is conservation of mass and energy when matter is transformed.
A unit that will develop a model for constant velocity using verbal, graphical, and quantitative representations. It begins with a paradigm lab using a constant speed toy cars (or any other similar device).
This activity is a part of the lesson plan "Shoes Under Pressure". In this activity students will design and build shoe prototypes that convert between high heels and athletic shoes. They apply their knowledge about the mechanics of walking and running as well as shoe design (as learned in the associated lesson) to design a multifunctional shoe that is both fashionable and functional.
This student handout is a supplemental resource to be used with the "Kinetic Energy Lab." The purpose of this lab is to investigate the relationship between mass, speed and energy.
In this activity, students investigate dynamics in the earth's crust that explain multiple Earth Science phenomena.
GeoInquiries are designed to be fast and easy-to-use instructional resources that incorporate advanced web mapping technology. Each 15-minute activity in a collection is intended to be presented by the instructor from a single computer/projector classroom arrangement.

Students will demonstrate how heating iron to a high temperature can cause it to lose his ability to be magnetized.
Students will be given a bag of materials and asked to find out how a current-carrying coil is influenced by a magnetic field. They will also construct models of galvanometers and DC motors using film cannisters.
In this unit, students will learn how two or more electrical devices can be connected to form an electric circuit. Lessons in this unit include: Circuit Symbols and Circuit Diagrams; Two Types of Connections; Series Circuits; Parallel Circuits; and Combination Circuits. This unit also includes videos, animations, and mini quizzes to check for understanding and facilitate learning.
Students will simulate radioactive dating by investigating the ratio of popped and unpopped kernels when microwaved for varying amounts of time
Students will develop experimentally procedures in which they compare the density of a whole candy bar to half or quarter of that same candy bar. Students will complete a lab report detailing their procedures, results, and conclusions.
In this demonstration students will observe ice cubes floating on cooking oil, and observe what happens to the liquid water produced as the ice melts, and the density changes. Several associated surface tension phenomena may be observed as part of the demonstration.
