Learners observe a scientific experiment and pose a hypothesis. In this scientific inquiry lesson, students make predictions about the combination of alcohol in water and how it will affect a floating ice cube.

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...

Students consider the concept of ocean pollution. In this ocean lesson, students participate in a hands-on demonstration in order to replicate an oil spill and its effects on marine life.

Students investigate surface tension and bubbles. For 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...

Students build a boat and make predictions. In this geometry activity, students design a cargo boat. They must show that the boat they designed can carry the cargo.

Students research inventors and inventions and their impacts. In this invention lesson, students research inventions and their affects in good and bad ways.

Students formulate a hypothesis using critical thinking skills. They use an orange to examine the displacement of water as the orange sinks or floats.

Students study the structure of the lungs. In this lung structure lesson, students use lung models to study the structure of lungs and experiment to measure the amount of air in the lungs.

Eighth graders determine the density using mass and volume. For 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...

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.

Learners illustrate Archimedes' Principle of Buoyant Force. In this graphing lesson, students will observe that the buoyant force on an object is equal to the weight of the fluid it displaces. Learners will then create a graph showing...

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.

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.

Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.

Young scholars will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.

First graders develop skills of scientific inquiry. They determine which objects float and which sink.

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.

Students 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.

Learners 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,...

Students observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the density...

Students apply knowledge about density of solids from previous experimentation to this activity which they investigate the density of liquids. They work in small groups to mix water and syrup, and water and oil to see what occurs....

Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.

Students complete a variety of activities using pumpkins. They visit various stations with various pumpkin activities.

First graders discover plate tectonics. They observe the forces of erosion. They observe the forces of weathering. They state three ways the earth changes. They record observations and make conclusions about their observations.
