Students calculate the densities of several liquids that appear similar.  In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in...

Learners explore how various substances change from a solid to a liquid or from a liquid to a solid and how temperature, pressure and nature play an important role in this process. In this melting and freezing...

We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity. 

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

Elementary schoolers practice measuring a soap bubble print. They follow a recipe to make a soap bubble solution. Pupils use the soapy solution to blow large bubbles with a plastic drinking straw until they pop leaving behind a circular...

There's nothing quite like a glass of ice-cold, freshly squeezed lemonade. Lesson seven of this series explains how the water humans need to survive can come in many forms. Teach your class about how much water humans require every day...

In this scientific method worksheet, students read over the basic steps of the scientific method and then apply those steps to a specific example. This worksheet has 8 short answer questions.

Students experiment with the cohesion of water molecules. In this surface tension lesson plan, students estimate how many drops of water a full glass can take before overflowing. They watch a video that explains water molecules.

Students observe and explain how a change in temperature causes a physical change in a substance.  For this physical science lesson, students use a soap making kit to observe the effects of adding heat to the bar soap as they...

Second graders listen to a book read to them entitled, WHAT MAKES A RAINBOW and recall and describe their five senses and what parts of their bodies use their five senses and then complete the Catch a Rainbow activity sheet using a...

Young scholars investigate common household items and classify them into types of matter. In this matter lesson, students group given items into categories based on their characteristics. They also complete a concept map about matter and...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

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...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

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...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Students compare and convert units of measurement within the United States customary system and within the metric system by baking cookies. Students discuss how to double the cookie recipe, how to make only half of the recipe, and how to...

How are skyscrapers built? What does it take to make a structurally sound building? How can one work within a budget to complete a building project? These guiding questions will be investigated and answered within a hands-on...

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...

Learners identify the stages of the water cycle. They listen to the book "Magic School Bus: Wet All Over," examine the Build Your Own Water Cycle website, predict and measure the amount of water in a jar for a week, and read a short play...

Third graders discovver what causes the dramatic colors of a sunset by seeing the changing color of light as it passes through a clear container of water to which milk is gradually added. They measure the liquids and observe what happens...

Three Dog Night isn't just the name of a band; it is also the way an Australian tribe, who used dogs to stay warm, would describe the temperature on a cool evening. After reading about many different ways of measuring temperature, the...

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...
