Ocean Layers I
How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...
Curated OER
Chemical and Physical Changes Lab
In this chemical and physical change instructional activity, students conduct a variety of experiments with unknown solutions and make observations. Students determine if the properties of the solutions have changed and if there is...
Curated OER
Volume of Gas
Eighth graders investigate the effect of temperature on the volume of a gas in a closed container. They measure the height of the water in their beaker/container, conduct their experiment, and create a graph to illustrate their data.
Curated OER
Quadrate Lab
Students investigate tree stems and conduct an experiment on how non living factors affect living factors. In this tree stems lesson plan, students observe and record physical characteristics, and make predictions on what factors will...

Soil Porosity, Moisture Content, pH, and Density
This lab activity does not have to be done with AP environmental scientists. It can also be done with middle to high school earth scientists. The procedures aren't complex. Learners determine the density of dry and wet sand in order to...
NorthEast Ohio Geoscience Education Outreach
Introduction to Density
Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities:
Measurement of the mass and volume of fruit in order to compare densities
Measurement of the mass of oil and water...

Silver Nanoparticle Synthesis and Spectroscopy
Certain materials do not always maintain the same physical properties when they exist in the nanoscale. Help your classes to explore this idea through an experimental instructional activity. Scholars use spectroscopy with samples of...
Cornell University
Discovering Enzymes
Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.

What's The Scoop?
Students explore the properties of matter. In this cross curriculum three states of matter science lesson, students listen to the poem "Eighteen Flavors" by Shel Silverstein, and predict what will happen if listed ingredients are...
Curated OER
Temperature Changes Everything
Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...
Curated OER
Slime and Intermolecular Attractions
Students explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.
Curated OER
Making Oxygen
Use demonstrations to enlighten learners on oxygen's role in combustion. Use potatoes and hydrogen peroxide to increase oxygen concentration in a jar, then stick a glowing splint and a burning wad of steel wool into the newly formed...

More on Conduction and Convection
Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...
LABScI
Surface Tension: Liquids Stick Together
Use science to help you walk on water! Young scientists explore the properties of liquids including cohesion, adhesion, and surface tension. They use graphs to compare different liquids and make predictions about their molecular attraction.

Water: The Liquid of Life
Sixth graders complete a lesson on the properties, types and amounts of water on Earth. In groups, they travel between stations to identify water resources in Illinois and pollution sources. They complete the lesson with a field trip...
Curated OER
Water Cycle
Students perform experiments with water to observe the principles of evaporation and condensation. They make models of the water cycle and discuss the processes that occurred in their experiments with their jars of water.
Curated OER
Elements and Compounds
Eighth graders explore the chemical and physical properties of a variety of elements in a lab setting. They organize the data they collect onto a spreadsheet and then choose one element from the periodic table to research. They...
