Students experiment to gain understanding of how a greenhouse retains heat.  In this greenhouse lesson, students work with soda bottles and simulate a greenhouse. Students compare data from a vented and intact bottle. Students...

Students recognize that some changes to matter are reversible and some are not.  In this matter instructional activity, students experiment a physical and chemical change. Students record experiment results in their science...

In these creative hands-on activities, students construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

In this chemical and physical change worksheet, learners are given details about chemical and physical changes. They are given 2 examples using water and salt and they identify 15 statements as chemical or physical changes. Students...

In this molecule worksheet, students use a molecular model kit to build the molecule, draw a three-dimensional structure, and describe its shape. This worksheet has 2 graphic organizers.

High schoolers explore the nature of water and water molecules. They examine the role of ice on organisms.

In this empirical formulas activity, students read about determining empirical formulas from chemical formulas. They determine the empirical formula given ten molecular formulas. They also find the molecular formulas given the mass and...

High schoolers interpret basic chemical formulas. When class begins, students interpret a "chemical formula" for fruit salad. After they interpret the recipe, high schoolers use the same strategies to identify chemical formulas. They...

High schoolers investigate plastic resins and their uses. In this plastics lesson plan, students describe major plastic resins and what they are used for, they compare and contrast the properties of plastic resins and they list products...

In this weird water worksheet, students read for information and assess comprehension. In this true and false, fill in the blank, and multiple choice worksheet, students answer ten questions.

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Students examine the concept that static electricity is a phenomenon that involves positive and negative charges. They explore the Static Electricity section of the Science, Technology and Engineering website to learn more about the...

In this covalent compounds worksheet, students answer 8 questions about bonding in covalent compounds, covalent bonds, and diatomic molecules. Students draw 2 dot diagrams showing covalent bonding. They answer 4 questions about bacteria...

Students investigate the 3 states of matter. For this physical science "matter" lesson, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on changing...

In this covalent compounds learning exercise, learners name 6 compounds given their chemical formulas, they write the formulas for 6 compounds given their chemical names and they answer questions about boiling points and solubility. They...

Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...

Students experiment with mixtures of matter. In this matter lesson, students investigate which liquids form a solution when mixed together and which do not. Students also identify which solids can be separated from matter.

Young scholars experiment with solids and liquids. For this mixtures of matter lesson, students combine matter to form solutions. Young scholars hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by...

Students explore how and why heat is produced from things that give off light, from machines, or when one thing is rubbed against another. They participate in several hands-on activities designed to help them realize that heat is related...

In this chemical reactions worksheet, learners compare endothermic and exothermic reactions, closed and open systems, and reactants and products. Students review physical and chemical changes and how to balance equations. This worksheet...

Don't be fooled by the title - this biology quiz could serve as an AP biology or college-level biology quiz. Some of the molecules represented may be difficult to identify without seeing the textbook from which this is based. It could...

Pupils develop a clearer understanding of how and why heat is produced from things that give off light, from machines, or when one thing is rubbed against another.

Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

Ninth graders explore the abstract idea of the atom and explain the differences and similarities between solids, liquids, and gases. They understand the molecular differences between solids, liquids, and gases.
