In this JAVA-based interactive modeling activity, students are introduced to the concepts of mass balance, flow rates, and equilibrium using a simple water bucket model. Students can vary flow rate into the bucket, initial water level in the bucket, and residence time of water in the bucket. After running the model, the bucket's water level as a function of time is presented graphically and in tabular form.

This activity is a series of game-like lessons that assist the student in developing the logic skills needed to read mass spectrometer output and formulate the identity of an unknown molecule. As students endeavor to identify the unknown they must apply fundamental chemistry knowledge including formula mass, isotopes, periodic table, relative abundance, interpreting graphs, organic chemistry, ionization, bonding rules, and structural formulas. Based on an activity presented by Olaf Runquist, Professor, Hamline University.

This simulation provides a realistic virtual mass-and-spring laboratory. Users can explore spring motion by manipulating stiffness of the spring and mass of the hanging weight. Concepts of Hooke's Law and elastic potential energy are further clarified through charts showing kinetic, potential, and thermal energy for each spring. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments in which students learn through exploration. All of the sims are freely available from the PhET website for incorporation into classes.

Students investigate the materials properties such as acoustical absorptivity, light reflectivity, thermal conductivity, hardness, and water resistance of various materials. They use sound, light and temperature sensors to collect data on various materials. They practice making design decisions about what materials would be best to use for specific purposes and projects, such as designing houses in certain environments to meet client requirements. After testing, they use the provided/tested materials to design and build model houses to meet client specifications.

This lesson is the first of a two-part series on the properties and uses of different materials.In Materials 1: Materials and Manufacturing, the familiar tale of The Three Little Pigs is used as an introduction to materials and manufacturing. Students examine the properties, limitations, and durability of a variety of materials, then evaluate which of the materials would be best for building a model house. If used in its entirety, this lesson could take several science class times.In Materials 2: Recycled Materials, students are introduced to the idea that some materials can be recycled.

In this lesson from the American Association for the Advancement of Science, students observe what happens to a closed container containing heated water is cooled. Students use their observations to construct an explanation of what happened. The lesson includes suggested questions for a teacher to use to probe student understanding as they make their observations. The lesson would be a valuable activity to include in a unit on states of matter to help students build understanding of the particle-level nature of matter. Connections to common misconceptions are included in the resource that can be used to guide teacher questioning durign the lesson.

This lesson begins with a demonstration of the deflection of an electron beam. Students then review their knowledge of the cross product and the right hand rule with sample problems. After which, students study the magnetic force on a charged particle as compared to the electric force. The following lecture material covers the motion of a charged particle in a magnetic field with respect to the direction of the field. Finally, students apply these concepts to understand the magnetic force on a current carrying wire. Its associated activity allows students to further explore the force on a current carrying wire.
