A helpful worksheet describes an interesting demonstration on the surface tension of water. Learners guess how many drops of water the heads side of a penny will hold. This resource does a great job of describing just how a penny can...

This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

Young scientists explore the concept of surface tension at is applies to water. In this activity, learners use a dropper to place drops of water on a penny. Each group guesses how many drops a heads-up penny will hold, then conducts the...

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

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

Students investigate the properties of water. In 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, pepper,...

Young scholars investigate water pollution. They develop an understanding of the behavior of organisms, of the structure and properties of matter, and of natural and human induced hazards by conducting lab tests. They present their data...

Students investigate surface tension using water striders. In this inquiry lesson, students develop a researchable question about the topic. They explain the environmental consequences of lowering water surface tension.

Learners explore the unique behaviors of water. They investigate surface tension using water drops on a penny and pennies dropped in a cup.

Students estimate how many drops of water can fit onto the surface of a penny and then test their hypothesis to find out. They also experiment with bubbles.

Learners drop water onto clean coins to determine the tension of each coin and then to graph their findings.
