Students design, build, and test the specifications (water displacement and load line) for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills.

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...

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...

In this solutions worksheet, students identify solutes and solvents from a list of solutions and they draw water molecules bonding to each other. They fill in the blanks with terms related to bonding in solutions, density of solutions...

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

In this solutions worksheet, students answer questions about the solubility of various substances in solvents such as oil in water and nitrogen gas in helium. They draw water molecules to show bonding between them and they diagram a...

Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...

Students are introduced to the forces that are responsible for generating waves in the ocean and how these forcesf differ from those that cause currents. They are able to explain how water molecules in a wave do not move in the direction...

The color, density, and smell of urine all relate to kidney function. Pupils observe the kidney controlling the concentration of water through three different steps. It mentions how each function might change the appearance and scent of...

Here is a post-experiment lab sheet that is to be used with an activity involving diet coke and regular coke. There is also a graph that learners must complete which goes along with an experiment on density and volume of a variety of...

Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.

Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...

Fifth graders define density as the amount of mass per volume a material contains, compare the densities of several types of materials, especially those that sink in water compared to those that float. They use two different methods to...

Fourth graders discuss density.  In this floating golf ball lesson students complete a lab activity on density while working in groups. 

Students experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.

In this worksheet, students calculate the density, molar mass, and volume of given word problems. Students also calculate the partial pressure of the gases given in the particular problem.

Young scholars identify important aspects of water quality such as slainity and turbidity. They test two of the water quality parameters and determine the quality of the water. In addition, they construct two sets of graphs based on data...

Young scholars 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 calculate the volume of scale model dinosaurs using a water displacement method. They use formulas to calculate the live mass each of the species of dinosaur. Then they complete and discuss a series of questions.

Pupils examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.

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

Students investigate population dynamics such as variation in density of females, composition of food sources an environmental factors such as light and temperature on Drosophila. They then relate their findings to human populations and...

Students design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.

Learners examine drops of water on several materials used on the outside of buildings. They make selective observations on and compare plastic, wood, brick, metal, roof tiles and glass.
