Using students' step length to understand the relationship between distance, speed and acceleration. Includes graphing of data and interpretation of graphs.
This resource folder provides an adaptation to two units in the OpenSciEd Curriculum: P.1 Energy Flow from Earth's Systems and P.5 Electromagnetic Rdition. Included is a varation on the student workbook that allows more space for student work to be completed, and embeds readings and activites. Also included in the folder are teacher resources pages that keep all important ideas, links, and other resources handy for each lesson.

In nature most elements occur as a mixture of two or more isotopes. Eachisotope of an element has a fixed mass with a natural percent abundance. The mass of theelement needs to reflect the masses of these isotopes in their respective abundances. Giventhe masses and abundances, how is the Average Atomic Mass determined?
In this activity, you will determine the atomic mass of the fictitous element Candium.
We use motion detectors and a bowling ball to find relationships velocity, mass, and energy.
Students investigate different balls' abilities to bounce and represent the data they collect graphically.
A 90 minute laboratory experiment utilizing observations and reasoning regarding the Law of Conservation of Matter and Energy.
Students investigate whether a bowling ball will float or sink in an aquarium of water after measuring the ball and determining the density. This is meant to be an investigative inquiry of the concepts of density and significant figures.
In this demonstration of chemical change, the presenter blows breath into a methylene blue solution releasing carbon dioxide which acidifies the water and changes it from a bright blue color to green.
In this interactive activity from the Building Big Web site, use your knowledge of bridge design to match the right bridge to the right location in a fictitious city.
Do you know how many calories are in a macadamia nut? This video segment highlighting a Calorimetry experiment will give you the answer.
Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture. This activity was inspired by the Cabaret Mechanical Theatre, a group of automata builders based in England. Artists like Paul Spooner, Keith Newstead, and Carlos Zapata build beautiful narrative pieces using elegant mechanisms based on cams, gears, springs, and linkages. Working with simple materials, this activity is easy to get started, and may become as complex as your mechanical sculpture ideas.
This video segment explains centripetal force and illustrates how roller coasters rely on it to give you a thrilling ride.
This video from NASA describes the detailed computer modeling used to predict that colliding neutron stars can produce gamma-ray bursts similar to those associated with black holes.
Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.
This is a laboratory exercise designed to allow students to further investigate the light spectrum. This lab is used to have students view the light spectrum first hand as opposed to using lecture alone.
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.
Successful completion of this cooperative learning activity requires the active involvement of the individual, the small group and the entire classroom (collaboration). The goal is to make a simple task as complicated as possible by constructing a single complex machine.
This interactive activity from ChemThink takes a closer look at a covalent bond--how it is formed and how the sharing of two electrons can keep atoms together.
In this interactive activity from the Building Big Web site, investigate dams in distress and decide if they should be repaired, removed, or left alone.
In this video segment adapted from ZOOM, cast members make a bridge from a single piece of paper. Will it be strong enough to hold a hundred pennies?
