Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...

Do polar opposites attract? After an introduction on the polarity of molecules, pupils are asked to design a self-assembling model using materials with different polarity. The challenge should motivate learners to develop a workable...

The first in a six-lesson mini unit, all using M&Ms® candies, this physical science activity gets kids to observe a single piece and discover what happens when it is placed in a plate of water. The activity can be used to...

Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...

Students explore the properties of water. In this cross curriculum art and physical science lesson, students experiment with a variety of materials to demonstrate the cohesive forces and adhesion of water. Students create a water color...

Students investigate the properties of water. For this chemistry of water lesson plan, students observe a demonstration of the properties of water using sand, sugar, oil, vinegar and salad dressing. Students experiment with water,...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Students investigate adhesion, cohesion and surface tension. For this molecular forces lesson plan, students observe multiple demonstrations that show surface tension, the attraction of water molecules to each other and the ability of...

In this chemistry worksheet, students respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

Students work together to explain the VSEPR theory and how it relates to molecules. They name electron pairs that can surround the central atom of an organism. They discuss the factors that determine the polarity of a molecule as well.

Young scholars conduct experiment with water striders by placing the insect in two different solutions and discuss their observations. They discover that weight and surface area are important factors in their experiment.

Learners examines the arctic food web with a short video about polar bears and an article about bears and warming temperatures. They design an arctic food web and discuss the trophic cascade that could come from climate...

High schoolers estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Students complete lab activities to investigate the "sticky" properties of water, such as surface tension and capillary action, due to the polarity of the molecules.

Middle schoolers make boats and race them. In this physics lesson plan, students investigate surface tension, molecules, and cohesion by competing in a class race with their boats. Middle schoolers experiment with liquid soap to see how...

In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.
