Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer probes the student's ideas about the arrangement and motion of particles in the 3 states of matter. When asked if atoms move, the student says in air they do but in aluminum they don't. When asked to draw, the student uses "dots" with gases spread far out, liquids closer together, and in solids he shades the picture to show that it is contiguous.

In-depth interviews with children that uncover their ideas about the topic at hand.,This segment provides an example of probing questions and phenomena used to elicit the student's ideas about motion of particles in a liquid. The student has several ideas about why the particles move including bubbles that popped, pressure, "commotion," waves, etc. but seems to lack the idea that the particles in a liquid have greater energy, hence more motion.

The student has the idea that gas atoms move freely but is limited by a model in which there are no boundaries. When presented with the phenomenon of air in a sealed bag, the student says they would stop because of the boundary.

Science in Focus: Force in Motion: Workshop 6: "Force Against Force"
Magnets stick to other magnets and to metal objects made of iron or steel. How much force is required to break the attraction between two magnets? In this workshop, fourth-grade students explore ways to balance the force of magnetism against the force of gravity. A magnet placed in a cup on one side of a pan-balance is stuck to a stationary magnet beneath the cup. When enough washers are placed on the opposite side of the balance, the magnets will separate. Graphical analysis shows some unexpect

Science in Focus: Force and Motion: Workshop 8. Bend and Stretch
We all expect a spring to stretch or compress when a force is applied, but forces can even deform solid objects like the floor or the top of a table. In this workshop, students in a high school classroom explore ideas about tension and normal force. By applying a force to a spring and measuring the distance the spring is stretched, the students calculate the force constant or stretchiness of the spring. Lecture demonstrations using student volunteers help to illustrate that even rigid objects be

Causal Reasoning
Does excessive exposure to violent video games cause violent behavior? Does increased gun availability cause more crime or less? Causal claims permeate everyday life and are constantly the subject of "studies" reported in the newspaper. The material in Causal and Statistical Reasoning examines the nature of causal claims and the statistical sorts of evidence used to support them. The material is contained in: approximately 20 content modules, a repository of over 100 short case studies, and a "C

Private Universe Project in Mathematics: Workshop 3. Inventing Notations
We learn how to foster and appreciate students’ notations for their richness and creativity. We also look at some of the possibilities that early work in creating notation systems might open up for students as they move on toward algebra.,Kenilworth Study: Pizzas In the fourth grade, the students encounter counting problems where the solutions cannot be built using standard manipulatives. As he invents his own notation systems, one student, Matt, builds on previous work to arrive at a solution

4.2 Subdivisions

In this subsection we formalise the idea of a net by introducing a useful concept called a subdivision of a surface. This is a standard kind of net drawn on a surface, and is defined in terms of vertices, edges and faces. It leads to the idea of the Euler characteristic of the surface.

All surfaces obtained from polygons by identifying edges arise from a net (of sorts) consisting of a single polygonal face, together with the edges and vertices that remain aft

Take Off with Paper Airplanes
This lesson introduces students to the art of designing an airplane through paper airplane constructions. The goal is that students will learn important aircraft design considerations and how engineers must iterate their designs to achieve success. Students first follow several basic paper airplane models, after which they will then design their own paper airplane. They will also learn how engineers make models to test ideas and designs.
