Cody's Science Education Zone
Students observe a scientific experiment and pose a hypothesis. For this scientific inquiry lesson, students make predictions about the combination of alcohol in water and how it will affect a floating ice cube.
Curated OER
Investigating Convection Currents
Students examine how differences in the temperature and salinity of the water help create ocean currents. They perform an experiment which shows how temperature affects the circulation of ocean water.
Curated OER
Introduction to AP Chemistry
Students are introduced to concepts in an AP Chemistry class. They work together to complete experiments on different materials. They discuss the results of the experiments.

Paper Chromatography
Young scholars use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Young...
Curated OER
Identifying Elements
Students use diffraction glasses to find similarities and differences between observed spectrum of fluorescent light and an incandescent light They work in groups of 4-6 for the experiment/activity part of this exercise.
Curated OER
Sea Floor Spreading I
Students use Excel to explore the geodynamics Model equation for ocean depth around a sea-floor spreading center. They complete an introductory tutorial on Excel for students with no prior Excel experience.
Curated OER
The Drag of Drag
Students are told that any object moving through a fluid (air, water, molasses, etc) experience a drag force which oppose the motion. They are given the summarized version of drag which is proportional to the square of the velocity....
Curated OER
Exploring the Interstellar Medium
Learners investigate the Interstellar Medium and the Local Bubble that the Sun is inside. They read and discuss a handout, answer discussion questions, observe a demonstration of light scattering, and conduct an experiment on the...
Curated OER
Physical/Chemical Properties of a Burning Candle
Learners investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.
Curated OER
Hot Gas Or Cold Gas Lab
Students engage in a lab project to study chemical reactions. They use guided questions to help facilitate the lab experience and come to the correct outcomes. The lesson does not contain a true understandable objective. The lesson could...
Curated OER
Observations & Chemical Reactions
Students conduct a series of experiments in which they explore chemical reactions. They detect chemical changes by observing how physical properties change when two different chemicals are combined. They list and describe the reactants...
Curated OER
Shake, Rattle and Roll
Young scholars compare the weathering of materials. in this weathering lesson, students experiment with the chemical and physical weathering of different materials. Young scholars use salt and water as an example of how weathering occurs.
Curated OER
Icebergs Ahead!
Learners examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.
Curated OER
Sunlight and Warm Air
Pupils discuss radiant energy from the sun, performing a simple experiment with sun glasses and bright light to demonstrate the concept. Students further participate in simple in-class experiments to demonstrate: air density as it...
Curated OER
Marine Debris on the Chesapeake Bay
Students examine problem of litter and marine debris on the Chesapeake Bay, and experiment with density of marine debris.
Curated OER
Clouds, Winds, and Weather
Pupils observe, record, and report weather conditions to learn how air mass densities determine the weather we experience daily. They demonstrate how clouds form, name clouds and predict the weather.
Curated OER
Floating Soap
Students explore the density of soap. In this science lesson, students conduct an experiment to find which types of soap will float. Students make a hypothesis and record their observations.
Curated OER
Cactus Wheel
Students explore plant biology by conducting field experiments outside of class. In this desert plant lesson, students discuss how cacti thrive in such dry climates and how dense their populations are. Students utilize action cards, a...
Curated OER
Hurricanes
Students state and directly experience two laws of Physics (Law of Gravity, Law of Centrifugal Force) that affect weather. They explain the observations made when using the "hurricane machine" and relate them to other events and phenomenon.
Curated OER
What's it Like Inside the Sun?
Students perform experiment in which they model convection as it occurs in our Sun. They also explain that convection acts where the effect of gravity and heat are present (low density fluids can rise and cool, and high density fluids...
Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
Curated OER
How's the Air Up There?
Students experiment with soda cans and water to discover why air pressure is greater closer to Earth's surface.
