A Fishy Tale
Eighth graders do a research project on a particular species of Atlantic seafood and record and graph information pertaining to commercial landings of that species of seafood. They use a website and an Appleworks spreadsheet.
Curated OER
Curricular Correlations
An interesting lesson on different types of soils is here for you. In it, learners discuss what soil is, and consider three piles of soil - clay, sand, and loam. During the rest of the lesson, third graders discover all sorts of...

Measuring the Effects of Gravistimulation on Plants
Students conduct an experiment to determine if a plant's response to gravity is affected by different angles of plant orientation.
Curated OER
Comparing Roots After Rotation of Ninety Degrees
Learners conduct an experiment and use different measurements of a single root to illustrate the mechanism of plant movement.
Curated OER
Observing the Growth of a Maize Root
Learners conduct an experiment in order to observe the typical downward growth of a maize root. They become familiar with the root's growth patterns to use as a control for comparison in other experiments.
Curated OER
Root Caps and the Effect on Gravity Sensing
Students conduct an experiment to determine how the absence of a root cap affects a plant's ability to sense gravity. They make comparisons between capped and decapped roots.

Jumping Frogs - A Lesson on The Scientific Method
Middle schoolers use origami frogs to experience the scientific method. They define different scientific terms. Also they test a hypothesis and draw conclusions from observations to go through all the steps of the scientific method.
Curated OER
Schoolyard Bird Project
Students observe and count bird sightings around their schoolyard throughout the school year.

WATER QUALITY FOR FRESHWATER ORGANISMS
Students use determination of dissolved oxygen and water temperature changes to determine the environmental impact from thermal pollution.
Curated OER
Properties of Matter
Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

The Sun's Energy
Sixth graders examine how the sun's energy arrives as light with a range of wavelengths. They discuss the characteristics of light, examine the color of light using a spectroscope, and conduct an experiment using water and thermometers....
Curated OER
Diurnal Temperature Changes and Water Vapor Content
High schoolers examine the greenhouse effect, as they determine how moisture in the air affects the diurnal temperature range. Their investigation help them to explain different climatological regimes of both the Southern Great Plains...
Curated OER
Measuring the Wavelengths of Visible Light
Students demonstrate use of an Emission tube power supply, a diffraction grating, and a scientific calculator to determine the different wavelengths of light.
Curated OER
Tie Dye
Students practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

Hurricanes
Young scholars research the formation and life-span of hurricanes and, after analyzing statistics, try their hand at plotting and predicting the course a hurricane.
Curated OER
Compass Deviation
Students identify and describe the difference between the magnetic north pole and true north. They consider why sailors could not steer a straight course to the New World from the Old.
Curated OER
What on Earth is in the Earth?
Students explore the physical properties of sand, soil, and rocks and sort, classify, compare, and contrast the materials found in the soil. The differences between the living and non-living parts of the soil is discussed.
