Mixtures and Nanotechnology
What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

Homogenous and Heterogeneous Mixtures
Fourth graders explain and describe what a mixture is, distinguish between the two types of mixtures (which are heterogeneous vs.homogenous) and are able to create and appropriately label mixtures.

I'm All Mixed Up
Middle school scientists compare and contrast heterogeneous and homogeneous mixtures. They differentiate solutions, colloids, and suspensions by examining samples of each. Note that the bulk of the lesson plan directs you how to...

Mixtures
Sixth graders experiment with mixtures. For this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

Chemistry 1 Practice Exam
Thirty multiple-choice questions and their answers are provided in this resource. It was written for a general chemistry course and queries test takers on scientific notation, mixtures, chemical symbols, electric charges, Dalton's atomic...
Curated OER
Mixtures Lab
Students classify different mixtures. In this mixtures lesson plan, students determine samples to be suspensions, colloids, or solutions and compare homogeneous and heterogeneous mixtures.
Curated OER
Mixtures
Students differentiate the two types of mixtures. In this chemistry lesson, students create their own mixture and classify them according to their type. They simulate steel production with the help of a guest speaker.
Curated OER
Mixing in the Kitchen
Students identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.
Curated OER
Pure Substances and Mixtures
Students compare and contrast the properties of substances and mixtures. For this chemistry lesson, students simulate spontaneous mixing by performing a short class activity. They differentiate heterogeneous and homogeneous mixtures.

Solutions, Suspensions, and Colloids
In this solutions, suspension, and colloids worksheet, young scholars answer questions as it relates to their reading information about solutions, suspensions, and colloids. Students observe different examples and complete a chart as...

Discover Ways to Further Classify Matter
Students analyze and classify substances. In this classifying matter lesson, students look at various substances and identify them as heterogeneous or homogeneous mixtures, pure substances, or solutions. Students bring something...
Curated OER
Overview of Cooperative Learning
Students identify the components of cooperative learning and plan a lesson plan using what they have learned.

Reduce Our Carbon Footprint, Let’s Compost!
Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready to start...
Curated OER
Properties of Materials - Part B
Students describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.
Curated OER
Concrete Research
Students explore concrete. In this physical science and computer research instructional activity, students work in groups to answer specific questions about concrete. Each group of students completes a different worksheet with a...

Worm Compost & Vermicomposting
Students explore vermicomposting, the species of worms needed and the proper climate for it. In this composting lesson plan students make their own worm compost bin.

Nuclear Reactions
For this nuclear reaction worksheet, students determine the missing particle from the reaction and then name that particle. This worksheet has 18 problems to solve.
Curated OER
Elements and the Periodic Table
Learners are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the lesson, they discover the characteristics...

The Greenhouse Effect and Me: How Do We Affect Each Other?
Ninth graders create a model of greenhouse effect in the lab. In this integrated science lesson, 9th graders investigate the different variables affecting this condition. They research about global warming and prepare a PowerPoint...
Curated OER
Stratification
Students study the process of stratification and seed dormancy. In this germination lesson students prepare a medium in which to grow seeds.

Reading
Learners participate in a jungle run in which they must group with the same people who hold the same cards with pictures of a tree, mushroom, deer or insect. In these groups, they read the definitions of sustainable development. Using...
