Middle schoolers define, give similarites and differences between solids, liquids, and gases. They compare and contrast a solid, liquid and gas in terms of shape, volume, compressibility, diffusion and density. Pupils classigy common...

Third graders explore the difference between a physical change in a substance and a chemical change. students study the volume, density, altering shape and chemistry of a copper penny.

Ninth graders explore how electricity is created and distributed through alternative production methods. Students participate in hands-on activities, research, lecture based instruction, and CD ROM resources.

Students investigate moles and Avogadro's hypothesis. In this moles lesson plan, students complete a worksheet by finding the volume of 1 mole of each substance given its density and they find the number of molecules, the formula, the...

Students investigate the properties of solids, liquids and gases. For this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...

Middle schoolers design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great activity on buoyancy!

Students are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its gaseous...

Learners explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.

Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

Students 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.

Eighth graders describe and identify the three layers of the Earth. They work together to construct their own earth model. They share their creation with the class.

Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.

Students use the Live Access Server (LAS) to form maps and a numerical text file of snow cover for each continent on a particular date. They analyze the data for each map and corresponding text file to determine an estimate of snow cover...

Students analyze cloud cover and to compose written conclusions to a given related scenario. They submit a letter of response and a report detailing their calculations and conclusions.

Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..

Students examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.

Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...

Students explore space science by completing a solar system identification worksheet. In this planets lesson, students discuss the different planets in our star system and identify their traits. Students complete an orbital system...

Students conduct an experiment to determine how different soils affect plant growth over a six-week period. After determining the physical properties of different types of soil, students plant various types of seeds into the soil...

Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

Learners compare and contrast the characteristics of the three different types of black holes. In this space science lesson, students research black hole's lifetime, location and evidence of existence. They present their findings to class.

Ninth graders explore the concepts of motion, velocity and acceleration through graphing their own movement using LoggerPro. They become more familiar with the computer technology. Students explore graphing in real time and graph on...

Middle schoolers examine computerized data maps in order to create graphs of the amount of snowfall found at certain latitudes by date. Then they compare the graphs and the data they represent. Students present an analysis of the graphs.

Young scholars engage in a lesson about the scientific concept of matter. They use essential questions in order to guide the research process. Students engage in several class inquiries that are hands on in order to investigate the...
