There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

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...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson can stand alone, but is best used as part of the...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

Introduce your classes to a fourth state of matter! Liquid crystals have a colorful sheen that changes based on different physical factors. Learners use this information to create a liquid crystal thermometer where the color of the...

Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...

Not many youngsters realize that solids aren't the only materials that can possibly be dissolved in water. During this investigation, they find out that some liquids can dissolve in water as well. This is part of a unit on solubility,...

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...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

Whether you're using a collection of Dr. Seuss books to teach basic math skills like counting, adding, and subtracting, or exploring the different states of matter by melting a crayon with a hairdryer, a series...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Titration experiments don't have to give your high schoolers a stomachache. Study the ways to titrate an acide with a base in an engaging science experiment, which involves creating solutions and performing titrations. Pupils...

What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...

Pour a solid foundation of engineering into the minds of future engineers. Scholars take part in three activities to learn about civil engineering. They build a model of a cable-stayed bridge, conduct an experiment to see the effects of...

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...

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson includes a range of learning experiences, from experimenting with the rate at which ice melts...

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...

Some of kids' favorite toys are the products of science experiments. Scholars follow precise measurements to mix and create their own slime and Play-Doh. They observe the changing textures and the chemical reactions throughout the...

Are serving sizes for different foods always appropriate for what you need? In this hands-on activity, learners work in groups to estimate what one serving size of various foods are, and then evaluate their hypotheses by measuring...
