Middle schoolers are introduced to the concept of buoyancy. The Video used in this lesson plan demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

For this gas law worksheet, students review the Idea Gas Law equation and practice applying the equation to chemical reactions. Students write the balanced reaction, determine the limiting reagent, moles produced, and volume of gas...

In this gas worksheet, students use the ideal gas law to find volumes of gases, pressure of gases, moles of gases, mass of gases and molecules of gases. They find unknowns at standard temperature and pressure and they calculate the...

In this chemistry review worksheet, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

Students determine the density and thickness of a piece of aluminum foil. For this density and thickness of materials lesson plan, students experimentally find the density of a piece of aluminum foil and compare it to the theoretical...

Students are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same group.

Students explore the concept of density and buoyancy. In this physics lesson, students discover the different factors that affect an object's density and buoyancy in water. Students conduct several investigations to further...

Students calculate the size of a molecule. In this molecules and their sizes lesson plan, students find the size of an oleic acid molecule by using a measured amount of drops of oleic acid to find the volume of the sample, the thickness...

In this buoyancy worksheet, students read about the principles behind objects floating including density, buoyancy and Archimedes' Principle. Students complete a buoyancy lab where they use a balloon and water and a film canister and...

In this properties of matter activity, students answer 11 questions about the various properties of matter such as density, elasticity, malleability, and how hard or brittle a substance is.

How does a hot air balloon fly? An experimental lesson has scholars build a balloon from a garbage bag and monitor the movement of air. As the temperature of the air in the balloon increases, gravity moves the denser cool air down,...

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...

Students determine the density of a material created in the laboratory and observe physical and chemical changes. They engage in a lab activity, and answer questions on a worksheet imbedded in this plan.

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

Change where an object floats in water. Pupils experiment with a Cartesian diver by squeezing on the side of a plastic bottle. Learners pay attention to the bulb of the pipette as the bottle is squeezed to determine what is happening...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

In this galaxy worksheet, learners calculate the volume of the Milky Way Galaxy, they determine the total mass, the density and the volume of the Milky Way Galaxy. They also solve 2 problems about the volume and size of the universe in...

In this solar system worksheet, students complete a database comparing the 9 different planets' mass, surface temperature, rotation period, orbital period, moons, and distinguishing features. This worksheet is a graphic organizer.

In this solutions worksheet, students solve twelve problems including calculating products made in reactions, determining limiting reagents, calculating molarity of solutions, determining percent composition, and finding volumes and...

Students study the concepts of motion, velocity, and acceleration through graphing their own movement using LoggerPro. They explain the difference between speed and velocity using the weather vane example. They discover the difference...

What's the moral of this story? Units save lives! Teach measurement conversion through storytelling in a quick math-based lesson. Young scientists learn how one country's decision to swap from imperial to metric standard units caused an...

In this planet models learning exercise, students use the radius of a given planet and its mass to answer questions using a model of a planet with a given radius. They determine the volume of the planet's inner core, the volume of its...

  Students build boats out of clay to test the buoyancy of the boat in water.  Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.
