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 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...

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 explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...

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...

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.

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.

Students investigate the states of matter. In this physics lesson plan, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Learners observe what happens to water as it goes from a solid to a liquid.  In this exploratory lesson students gain an understanding for the water cycle while working in groups observing what happens to water as it changes...

Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

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.

This open-ended boat building exercise is meant to be part of a three-instructional activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat,...

There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...

Pupils research the process of fractional distillation. In this chemistry lesson, students perform simple distillation of two liquids. They collect data and share results in 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 investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

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.

Middle schoolers explore geometry by completing a physics activity on-line. In this mass measurement lesson, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete an on-line...

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.

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...

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...
