How do robots assist ocean explorers in collecting data and images? The final installment in a five-part series has science scholars examine underwater images collected by robots and identify the organisms shown. Groups then calculate...

Students conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...

Students investigate Canadian people by researching the geography of the country.  In this world geography lesson, students identify locations within Canada with large populations based on their access to waterways.  Students...

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.

Students experiment with density of ice, and examine how density affects how icebergs float in water.

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

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 experiment with soda cans and water to discover why air pressure is greater closer to Earth's surface.

Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...

Students measure volume using water displacement and mass using a balance. Once they have calculated these two values they will then calculate density while at the same time working on long division. After the activity and explanation of...

Eighth graders measure strike and dip of given land features and explain the difference between them. They also look at rock and mineral samples for indentification, along with calculating the density. Finally, information is analyzed...

Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.

Students research the development and implementation of a research vessel/vehicle used for deep ocean exploration. For this oceanography lesson, students calculate the density of objects by determining the mass and volume.

Students determine how to use a quarter meter quadrant to find population density, relative density, frequency and how to calculate a diversity index while participating in a virtual field trip. They study how to establish a Correlation...

Fifth graders investigate buoyancy by conducting a science experiment.  In this water properties lesson, 5th graders predict which of their different paper boat designs will float for the longest period.  Students conduct the...

Students discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes. They...

Pupils discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.

Students explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

Students observe a demonstration of Lenz's Law using an aluminum can and a bar magnet. They hypothesize what will occur as the can is placed in water and the magnet is lowered above it on a string. Students discover the phase shift...

Students participate in a virtual field trip to Lake Superior. In groups, they perform experiments in which test the level of toxins and bacteria in the water. They also watch video segments life in the lake and discuss their observations.

Students discuss the relationship of density to stratification. In this marine science lesson, students create a model of upwelling events using cold and warm water. They discuss how water phenomena affect coral reefs.

Students experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...

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...

Students review properties of materials and define what pH tells them about matter.  In this pH levels lesson, students determine whether materials are acids or bases using indicator substances.
