Students predict then calculate and graph profit-maximizing the price for an isolated, desert monopoly gas station.

In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the motions of the Moon about the Earth and the Earth about the Sun, and then test their understanding using an experimental apparatus made from a cardboard or plywood disk and rope. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

?What is Motion Diagrams in one dimension هذه المحاكاة تتحدث عن الحركة في بعد واحد

Try the new "Ladybug Motion 2D" simulation for the latest updated version. Learn about position, velocity, and acceleration vectors. Move the ball with the mouse or let the simulation move the ball in four types of motion (2 types of linear, simple harmonic, circle).

This simulation is about Motion with Constant Acceleration

This module is focused on increasing the users understanding and familiarity with the fate and transport of contaminants. Video clips of sand tank models showing the movement of contaminants in subsurface porous media are included. The sand tank models provide a visual guide to help see how different geologic materials with different permeability's effect the movement of fluids and ultimately the distribution of contaminants.

Learn about position, velocity, and acceleration graphs. Move the little man back and forth with the mouse and plot his motion. Set the position, velocity, or acceleration and let the simulation move the man for you.

Explore how changing the DNA sequence can change the amino acid sequence of a protein. Proteins are composed of long strings of amino acids. Proteins are coded for in the DNA. DNA is composed of four different types of nucleotides. Converting the information in DNA into protein is a two-step process, involving transcription and translation. In transcription each mRNA nucleotide pairs with the complementary DNA nucleotide. In translation, each tRNA nucleotide pairs with the complementary mRNA nucleotide. Thus, a change in the DNA sequence can change the amino acid sequence of the protein. There are three basic types of mutations: insertion, deletion and substitution. Some mutations are silent, meaning that there is no change in the protein, while others can cause major changes in the protein.

Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

The NOAA Sea Level Trends map illustrates U.S. regional and some international trends in sea level, with arrows representing the direction and magnitude of change. Students can investigate sea level changes around the U.S. and some worldwide using an interactive map interface with supporting data plots and tables.

This data viewing tool from NOAA offers nearly instant access to dozens of datasets about Earth through an engaging interface. Users can select data categories from atmosphere, ocean, land, cryosphere, and climate and drill down from there into more detailed categories.

Access and explore large datasets from the National Health and Nutrition Examination Survey (NHANES, 2003). Working with large datasets that emphasize exploration, finding patterns, and modeling is an essential first step in becoming fluent with data. This activity is a great place for students to start, since the dataset is straightforward and students can decide on the data they want to explore, including height, age, weight, and many other health-related attributes. Students begin by selecting and then investigating subsets of the dataset, for example, to find the cholesterol level of U.S. citizens. Then, working with their classmates or individually, students can try their own data science challenges, such as finding health trends in a subset of Americans by their household income, age, or marital status, etc.

This activity uses a cultural story to excite kinesthetic homework, nature journaling and daily adventure in a child's own back yard or kitchen flower pot.

In this activity students read articles or excerpts of books to explore the topic of sustainability in terms of food webs, roles of plants, animals, fungi, and bacteria and their own food choices. Students continue their exploration of these kingdoms with a visit to a farmers' market and a grocery store to compare locally grown foods and grocery store selections.

This activity is a classroom lesson on how a slinky relates to sound waves and how sound waves relate to the human ear.

Produce light by bombarding atoms with electrons. See how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.

Stimulate a neuron and monitor what happens. Pause, rewind, and move forward in time in order to observe the ions as they move across the neuron membrane.
