A lesson on states of matter using marbles for molecules expands into 3 more lessons elaborating on properties of a gas.
The goal of this laboratory is to help students understand that burning fossil fuels, which results in an increase in the acidity of ocean waters, has a detrimental impact on marine life (specifically coral but also other organisms that have calcium carbonate based shells).

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.
In this middle school and high school unit, students compare and constrast Arctic expeditions of the past (1893-1896 Fram expedition) and the present (2019-2020 MOSAiC expedition) to prepare for the Arctic of the future.

Once the pride of the German Navy, this 700 foot long heavy cruiser was used by the U.S. as a test target for not one but two atom bombs at Bikini atoll. Today, at the bottom of the ocean, the radiation levels of the Prinz Eugen are low enough for safe exploration. In this video, Jonathan joins historian Mark Miller on a trip to explore this mysterious shipwreck. What they find about the condition of this wreck is surprising. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.
This activity provides for small group investigation of the properties of different liquids leading to the discovery that liquids are different in many ways, including density.Students would be led to a very beginning understanding of density.
¿Podemos ver el ADN de un plátano a simple vista?En este experimento vamos a comprobar cómo mediante los procedimientos sugeridos podemos llegar a visualizar la cadena de ADN de un plátano. Para ello, sólo tenemos que seguir los pasos que se plantean a continuación.
Join Tarissa and Sabrina as they measure and compare the volume of different sounds across New York City in this video from DragonflyTV.
In this video segment adapted from Interactive NOVA, astronaut John Young experiences extreme temperatures on the Moon that are a result of the Moon's low gravity and lack of atmosphere.
This lab activity is designed to have students use their knowledge of balancing and identifying chemcial reactions and apply it in a fun and interesting way!
This interactive visualization created by FRED (Free Energy Data), displays energy supply (by source) and demand (by use) for each state in the US from 1960 to 2010; forecasts through 2035 are available as well. FRED is an open platform to help state and local governments, energy planners and policy-makers, private industry, and others to effectively visualize, analyze, and compare energy-use data to make better energy decisions and form sustainable strategies.
This lesson is a presentation of famous scientist throughout history where the students will learn and take notes about the contributions and discoveries made in science.
Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!
Light a light bulb by waving a magnet. This demonstration of Faraday's Law shows you how to reduce your power bill at the expense of your grocery bill.
This module provides an introdcution to the concepts of fats and proteins. The basic chemical structure of fats as triglycerides is reviewed, and an introduction to protein structure, including the peptide bond is given.
Students study an ancient bronze statue, analyze its pose, and discover how conservators remove and prevent corrosion. They learn that the bronze used to make this sculpture is an alloy of copper and tin with small amounts of antimony, lead, iron, silver, nickel, and cobalt. They use the periodic table to research the chemical formulas of compounds used to make bronze. After learning about oxidation-reduction reactions that occurred in the statue, students speculate about the conservation techniques needed to conserve the bronze sculpture.
Students study an ancient bronze statue, analyze its pose, and discover how conservators remove and prevent corrosion. They learn that the bronze used to make this sculpture is an alloy of copper and tin with small amounts of other elements. They use the periodic table to research the chemical formulas of compounds used to make bronze. Students compare conservation techniques in two ancient bronze objects.
In this activity, students critically analyze prior conceptions and textbook visuals of the relative sizes and orbiting distance of the Earth-moon system (and other bodies in our solar system), search out sources for this data, and construct scale models by using balls of various sizes. There are tips for helping learners understand the large scales (i.e., millions rather than thousands) that characterize our solar system, and examples are provided of scaling using different sizes of athletic balls.
This activity is an observation lab where students observe the colors emitted by various metal ions in salt solutions.
