Curated OER
Laboratory - Density of a Material
Students conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.
Curated OER
Mixing Colors
Students listen to a story about mixing colors. They explore color using cups of water, color and coffee filters. They use sight word vocabulary to describe the colors.
Curated OER
Density Stratification and Ocean Circulation
Students examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.
Curated OER
The Effects of Solar Energy
Students examine how solar energy is absorbed and used. In this solar energy lesson plan students complete several activities that allow them to better understand solar energy.
Curated OER
Strive to Survive
Learners identify the effects of drugs on the reward system by completing a collection activity.
Curated OER
Density Currents
Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.
Curated OER
Why is the Sea Salty?
Students conduct a hands-on activity to investigate salt concentrations in water and how salt remain after water evaporates. They can also do a Saltwater Painting to once again observe the evaporation. process.
Curated OER
Transportation System of a Tree
High schoolers examine the transportation system of a tree and the speed with which nutrients and water move. Cross sections of the samples used are examined in class for experimental results.
Curated OER
Chemical Reactions With Vinegar
Second graders observe chemical reactions. In this scientific inquiry lesson plan, 2nd graders determine whether vinegar creates a chemical reaction by observing two different experiments. A list of 7 supplies is included. In addition,...
Curated OER
A Salty Experiment
Students study salty and fresh waters. In this harbor estuary lesson plan students complete a lab activity on salinity and describe what happened.
Curated OER
Modelling Ocean Currents
Learners construct a replica of the Atlantic ocean given certain parameters. In this earth science lesson, students draw their own map of ocean currents. They answer questions related to the activity.
Curated OER
Immiscible Liquids and Density
Students will make a lava lamp. In this density instructional activity, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.
Curated OER
THE SPREAD OF AIDS
Students perform a hands-on activity in which they simulate the spread of a disease such as aids. One student with unknowingly be the "carrier" of the infection and Students witness how fast it can spread.
Curated OER
Frozen Solids
Middle schoolers investigate various properties of ice including melting points and the effect of pressure on ice. They demonstrate how increased pressure lowers the melting point of ice and perform a simple experiment proving that water...
Curated OER
Watery World
Students brainstorm to develop resource/reference charts for later use. they are introduced to Microsoft Word and to an internet movie site. They use prepared chart headings, to respond to questions posed on each chart such as: Where do...
Curated OER
Air Pressure is Powerful
Students construct a barometer and collect data on the changes in air pressure. They work is small groups using plastic tubing, corks, and green food coloring. They then use a formula to convert inches of mercury to barometric pressure...
Curated OER
Pipeline to the Coral Reefs
Students discuss the relationship of density to stratification. In this marine science lesson, students create a model of upwelling events using cold and warm water. They discuss how water phenomena affect coral reefs.
Curated OER
Frozen Film
Students are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.
Curated OER
Oregon Rainshadows
Students brainstorm list of possible highest locations in Oregon, identify and label places from list on map using color code, and discuss and identify causes of a rain shadow.
Curated OER
Beaches of the Delaware Estuary
Middle schoolers examine estuaries in Delaware. They, in groups, gather samples of water to find organisms and identify them.
Curated OER
Surface Tension Grabbers
Students explore why surface tension is such a very important biological concept. Determination is made on why the myriad of biota that interacts at the air-water interface are vital components of aquatic and marine ecosystems. They...
Curated OER
Chlorine-Bleached Paper
Students analyze the effects of pollution and other types of ecosystem devasation caused by chlorine. They examine alternative technologies that allow for the bleaching of paper without using chlorine. They discover what they can do to...
Curated OER
The Magic School Bus Goes to Mussel Beach
Students participate in a hands-on activity where they explore tidal zones. They explore tides and marine life. This is an experiment that can be accomplished in class.
Curated OER
From Caterpillar to Butterfly
Students read and discuss the book about the butterfly and create their own butterflies using liquid watercolors and pipe cleaners. They then create a butterfly development book, included in the instructional activity, and color the...
