…build student understanding of science practices, crosscutting themes and core ideas all at the same time. Figure 1. Molecular Workbench models flexibly demonstrate concepts such as the effect of atomic…
…using Google Translate). It is these successful applications of Energy2D in the real world that will make it a relevant tool in science and engineering for a very long time….
Unit 1 – Inv. 2: What are factors that affect the interactions between objects? (v2) Learning Resource
…Students analyze how the charge on objects and the distance between them affects the strength of the interactions between those objects. This investigation builds toward NGSS PEs: HS-PS2-4 and HS-PS3-5….
The rate of heat flow between two objects is proportional to their difference in temperature. One experiences this every day, with stoves, outdoor weather and touching things. If you touch…
In this activity, you will use a temperature sensor to relate changes in sunlight to the temperature of the air trapped in a container.
Most buildings have leaky places where air can enter or escape — around windows, ceiling openings like pipes, wires or chimneys, and construction joints such as where the wall meets…
Heat flows through solids at rates measured by their conductivity. The rate of heat flow is also proportional to the thickness of the material. This model compares the rate of…
…effect. This effect, which is totally based on molecular reasoning, is yet to be confirmed by an experimental method. The vapor pressure lowering process and the crystallization process in this…
…iPhone can *tell* him verbally what colors he’s “seeing.” However, he mistakenly tries it for the first time in the dark: I have never experienced this before in my life….
“Look over there, that’s Orion. And there’s Ursa Major.” If you can you pick out the stars in the night sky and understand how they move, there’s a good chance…
