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...

Students will make a lava lamp. In this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

Middle schoolers work with a partner to record observations on various materials. Working together, they calculate the mass and volume of each material and then combine them and shake them for a period of time. In their journals, they...

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

Pupils comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...

Pupils 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.

Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...

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 investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Students analyze which items float and do not while...

Students analyze density. In this density instructional activity, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Students explain the importance of water in our daily lives. In this aquatic science lesson, students identify different ways to purify water and make it potable. They design and construct a water filter based on researched information.

Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.

Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...

Learners explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Learners examine the objects over five days...

Students investigate density. In this density lesson, students conduct an experiment using food coloring. Students observe the differences in mixing food coloring in water and oil.

Tenth graders experiment with floating and sinking objects and heavy and light liquids, using correct terms, like density, to explain what happens.  In this Hindenburg lesson plan, 10th graders watch a demonstration called the...

Students examine and discuss how atoms change from solid to liquid to gas. They inflate a balloon by melting ice that converts to steam, and discuss the results.

Insolubility and density? Yup, it's art class, of course. To create insoluble paintings that continually move and change, kids mix water-based paint with mineral oil and seal the mixture in laminating pouches.

Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.

Students consider the effects of temperature on water density. In this Earth Science lesson, students evaluate a demonstration of cold and hot water currents in a model. Students use two liter bottles and varied water temperatures with...

Students explain how melting glaciers affect global warming. In this earth science lesson plan, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Students examine the properties in oil in water. In this mixture instructional activity, students read about the Lophelia II 2010: Cold Seeps and Deep Reef Expedition and look at images of deep sea ecosystems. They experiment or...

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...
