Diffusion
Learners develop the concept of diffusion. In this science lesson plan, students demonstrate diffusion of molecules of matter in various states.
Curated OER
Differentiate Elements, Compounds, and Mixtures
Pupils examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and covalent...
Curated OER
Creative Expressions: Phase Changes
Students place themselves in the position of a water molecule, ice molecule, or steam molecule and then describe the process of changing phase.
Curated OER
Heat And Heat Transfer
Students role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...
Curated OER
Earth's Atmosphere and Temperature
Pupils explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...
Curated OER
Rate of Solvation
High schoolers test factors that may affect the rate at which sugar dissolve in water. They conduct two studies: One is to test the effect of temperature on the rate of solvation and the other is to test a factor which Students come up...
Curated OER
Ice Cold
Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.
Curated OER
Amazing Water Changes
Pupils explore the properties of water and how it changes states. In this kindergarten to 2nd grade science instructional activity, students pair a hands-on science activity with two suggested books. This inquiry...
Curated OER
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...
Curated OER
Using Ion Exchange Chromatography to Separate Proteins
Students explore protein purification by separating a positively charged molecule, lysozyme, from a negatively charged molecule, albumin, at neutral pH using ion exchange chromatography.
Curated OER
Pauli's Magical Water
Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.
Curated OER
Exploring Magnetism
Twelfth graders experiment with magnets in order to visualize that magnets have a north and south pole, some materials can be magnetized, and magnetization occurs because of the magnetic moments of individual molecules in matter.
Curated OER
Einstein's BIg Idea
Pupils discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.
Curated OER
Learning Lesson: Sweatin' to the Coldies
Students participate in a demonstration to show the change of water vapor to a liquid. They discuss the three states of matter. They examine flash flood safety to end the lesson.
Curated OER
Chemical Bonding
Eighth graders identify the three main types of chemical bonds. In this chemistry instructional activity, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.
Curated OER
How Much Do I Know About Water?
Sixth graders explore how water behaves on a penny. In this states of matter lesson, 6th graders observe water as they add drops to a penny. This lesson helps students apply the adhesive properties of water to the water cycle.
Curated OER
Density and Mass
Students experiment to find which liquids are more dense. In this density and mass instructional activity, students predict and then test objects to observe and measure their density. students observe which items sink and float....
Curated OER
Lose Some Weight- Evaporate!
Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...
Curated OER
Making "Cents" of Surface Tension
Students explore the unique behaviors of water. They investigate surface tension using water drops on a penny and pennies dropped in a cup.
Curated OER
Properties of Salt
Students see how the properties of salt affect the color of flame, the flow of electricity, and the freezing temperature of water. They identify salt and sugar crystals under a microscope and discuss various practical uses of salt.
Curated OER
The Absorption of Solar Energy
Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...
American Chemical Society
Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...
