Learners solve 14 word problems and 25 weight conversions.

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

Tall and skinny or short and stout, which glass hold the most liquid? Learners analyze dimensions of cylindrical glasses to determine the one holding the greatest amount of liquid. They brainstorm the relevant dimensions before making...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

Differentiated instruction through leveled learning contracts boosts scholars' knowledge of volume and capacity. Participants split into three groups based on ability and interest before choosing three activities from their learning...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

Yuck, does my deodorant kill that? To test whether deodorant is anti-bacterial, class members use petri dishes to grow control bacteria and bacteria from sweat, and then compare them to see if deodorant effects the...

Your Algebra learners analyze and solve an exponential equation in this popular, real-life model of the cooling of a liquid.  

Explore the consistency of the earth's layers and soil through modeling. By conducting an engaging experiment, learners develop a model for the earth's layers and a soil profile using edible materials. Each material is chosen based on...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

How do cohesion and adhesion work together? The third installment of a nine-part series teaches young scientists the difference between adhesion and cohesion. They also learn how cohesion and adhesion work together to cause capillary...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Students identify the various states of water. They use hypothesizing and hands-on experimenting on changing the states of water, the properties of water, and the role of heating and cooling in the changes of state.

Students explore the world of nanotechnology by synthesizing ferrofluids in a series of chemical reactions. In small groups, they follow the procedure to create the ferrofluids using precise measuring techniques. They test the resulting...

It's assessment time! Determine your young mathematicians' understanding of elapsed time with this brief, five-question quiz.

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

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...

Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...
