Cody's Science Education Zone
Learners observe a scientific experiment and pose a hypothesis. In this scientific inquiry lesson plan, students make predictions about the combination of alcohol in water and how it will affect a floating ice cube.
Curated OER
Save the Bay
Students explore the concept of environmental stewardship. In this science lesson, students examine the environmental effects of oil spills as they replicate a contained oil spill and clean up.
Curated OER
Pumpkin Science
Students investigate how plants grow by analyzing pumpkins. In this agricultural lesson, students read The Biggest Pumpkin Ever by Steven Kroll, and draw pictures of a pumpkin in each of its growing stages. Students measure and dissect...

Ocean Pollution & its Effect on Aquatic Animals
Students consider the concept of ocean pollution. In this ocean instructional activity, students participate in a hands-on demonstration in order to replicate an oil spill and its effects on marine life.
Curated OER
Boat Design
Young scholars build a boat and make predictions. In this geometry lesson, students design a cargo boat. They must show that the boat they designed can carry the cargo.
Curated OER
Surface Tension and Bubbles
Students investigate surface tension and bubbles. In this scientific inquiry lesson plan, students explore how the surface tension of water is able to support tiny objects that actually weigh more than the water as they collect date by...

Inventions 2: The Impact
Students research inventors and inventions and their impacts. In this invention lesson, students research inventions and their affects in good and bad ways.
Curated OER
Water Displacement
Students formulate a hypothesis using critical thinking skills. They use an orange to examine the displacement of water as the orange sinks or floats.
Curated OER
How Do We Breathe?
Learners study the structure of the lungs. In this lung structure instructional activity, students use lung models to study the structure of lungs and experiment to measure the amount of air in the lungs.
Curated OER
i-Density Crisis
Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...
Curated OER
Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
Curated OER
Buoyant Force
Students illustrate Archimedes' Principle of Buoyant Force. In this graphing activity, students will observe that the buoyant force on an object is equal to the weight of the fluid it displaces. Students will then create a graph showing...
Curated OER
Introduction to Density
Seventh graders define density in their own words. In this physics lesson, 7th graders solve density problems using its mathematical formula. They explain why some objects flow and some sink.
Curated OER
Trash Traits: Marine Debris, Litter, Ecology, Oceans
Students perform experiments to examine whether trash can float, blow around, or wash away. The effects of these characteristics on the presence of marine debris in the environment are then discussed.
Curated OER
Investigating Density: Heavy Ice
Learners end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.
Curated OER
Marine Debris
Students will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.
Curated OER
Science: Exploration Tubs
First graders develop skills of scientific inquiry. They determine which objects float and which sink.
Curated OER
What Animals Live in the Rice Paddy?
Students listen to a story about turtles leaving a rice field to go to sea. In this literacy and social science lesson, students discuss the story, write a sentence describing each turtle, and draw a picture of the turtle's home in the...

Galapagos Rift Expedition Come On Down!
Students research the development and implementation of a research vessel/vehicle used for deep ocean exploration. In this oceanography lesson, students calculate the density of objects by determining the mass and volume.
Curated OER
Condiment Diver: The World's Simplest Cartesian Diver
Middle schoolers explain what density is in their own words. In this physics lesson, students perform the condiment experiment and explain why some float and some sink. They share their findings in class.
Curated OER
Let's Get Carried Away
Students discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...
