The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

High schoolers discuss the difference between atoms and elements. They analyze how compounds are formed. Students discuss the difference between covalent bonds, hydrogen bonds, and ionic bonds. They review bonding with diagrams,...

Learners classify compounds as ionic or covalent. In this chemical bonding lesson plan, students experiment with 6 chemical compounds. They test physical properties such as the melting point, the solubility and the electrical...

Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

Through three activities, first-time physical scientists wonder at the properties of water. Freeze some soda cans and a container of water prior to the investigation to show that water expands when frozen. Lab groups experiement with...

Students investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to denature...

Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the lesson. Copious, comprehensive...

Students view demonstrations that illustrate the surface tension of water. In this properties of water lesson, students observe demonstrations that show how water exhibits surface tension. They explain how the demonstration shows surface...

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...

How attractive is your intermolecular forces lesson plan? Draw your class in with an activity that includes research, presentation, and demonstrations. Chemistry scholars work together to create claims about the each intermolecular...

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.

Explain the properties of water. Identify the properties of water that make it a polar molecule Describe hydrogen bonds and how they differ from covalent bonds Discuss the differences between hard water and soft water Compare the heat of...

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,...

In this drawing Lewis structures worksheet, learners read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

Glucose is a simple sugar and a molecule that can be illustrated through modeling. Scientific investigators with visual impairments use hands-on models to reconstruct the process of bonding molecules. The tools used in this activity are...

Students in pairs, select and view proteins from the Protein Data Bank. After downloading the tutorial and instructions, they identify the protein's structures and primary biological functions. Then, students present their findings to...

Students cuminate their study of molecular structure and bonding with this activity.

Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Students discuss photosynthesis. They explore and discuss surface tension, hydrogen bonding and capillary action with hands on experiments. They make journal entries and draw pictures of the different stages of the experiments.

Students construct models of hydrocarbon molecules using candy and toothpicks. In this hydrocarbons lesson plan, students are given a sheet with the molecular formulas of hydrocarbons. As a group, they construct each molecule using...

A chemistry lesson presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Students observe and record what occurs when yeast is added to hydrogen peroxide. They indicate why a chemical reaction (decompostion) must have occurred during the experiement. Pupils explain why yeast was used. Students comprehend the...
