Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

Middle schoolers watch as the teacher demonstrates: if a single liquid is placed in a U-shaped tube, the level of liquid on both sides are the same. When the mass is greater on one side than the other, liquid is pushed from one side to...

Students explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Students observe fluid motion. For this Physics lesson, students explore the principles of Pascal, Archimedes, and Bernoulli. Students list their experiences with fluid movement.

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.

Young scholars conduct a series of investigations on the unique properties of water. In this general science instructional activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine...

There is a specific zone, or distance from a star, that a planet must be in order to have water in a liquid form. The activity demonstrates how flux density depends on its distance from the source. A photovoltaic cell gets power to...

Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

Students participate in a mini lab to explore density.  In this density lesson students view a demonstration and answer questions. 

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Students 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...

Students investigate what happens to solids and liquids when they change from one form to another. The amount od space taken by frozen water begins the discussion and students are led to formulate their own hypothesis to research.

First graders observe water changing states from a solid to a liquid to a gas. They predict what they think happen to ice cubes as they sit out. They paint water with paintbrushes outside the classroom in the sun and watch the water...

Young scholars examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph...

Students explore measurement and units. They measure eggs to determine their density, mass and percent composition. An inquiry approach is used for students to ascertain the mass.

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.

Students investigate the density of liquids. In this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Fifth graders discuss the properties and characteristics of different substances. They find the viscosity of each substance while at room temperature, when heated and when cooled. They determine if the viscosity of a substance changes...

Eighth graders create solutions with 5 different densities. In this chemistry lesson, 8th graders analyze the density of solutions stacked on top of each other. They document their data through graphing. This assignment requires 4 class...

Seventh graders explore the the constituents and properties of matter. They use the scientific process while exploring solids, liquids, gases, the mass, volume and density of matter. Students plan and conduct an investigation to measure...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...
