In this stoichiometry worksheet, students solve thirty problems using the process of stoichiometry to find moles, molecules, and masses of substances in chemical reactions. Students balance chemical equations, find limiting reagents and...

A great review of the structure and function of carbon-based molecules important to life, especially with relevance to humans. The chemistry behind the combination of polymers and the breakdown of bonds is covered. Valuable content...

In this heat transfer and phase change worksheet, learners experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

In this water worksheet, high schoolers explore the reasons why water is considered a universal solvent. Students compare different ways to change the dissolving rate of a solute. This worksheet has 11 fill in the blank and 8 matching...

In this states of matter activity, students are given 15 statements and they fill in the blank with terms related to solids, liquids and gases and the transition from one state to another. Students use the clues to complete a crossword...

In this thermochemistry instructional activity, learners indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Learners...

Students examine how a hot air balloon works. In this hot air balloon lesson, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when turned to a liquid.

In this physical and chemical change worksheet, students watch a movie called the "Brain POP" about property changes and fill in the blanks to complete 8 sentences which are examples of chemical and physical changes.

In this chemical equations worksheet, students determine the products and reactants for given equations and then balance the equations. This worksheet has 4 problems to solve.

Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final instructional activity in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter...

In this solutions worksheet, students identify solutes and solvents from a list of solutions and they draw water molecules bonding to each other. They fill in the blanks with terms related to bonding in solutions, density of solutions...

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.

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

After giving basic details about the properties of Carbon, some of the common functional groups and molecules are featured. There are some details about specific functions and impact on the human body. The diagrams are helpful and could...

In this solutions worksheet, students answer questions about the solubility of various substances in solvents such as oil in water and nitrogen gas in helium. They draw water molecules to show bonding between them and they diagram a...

Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...

Young scholars investigate air by participating in a class experiment. In this matter measurement lesson, students identify air as a gas which consists of mass. Young scholars utilize a windsock or balloon to measure oxygen and explore...

All different types of bonding are covered in this PowerPoint, along with details of resulting bond and molecule shapes. The definitions of traditional molecule shapes and characteristics of behavior are very useful to assist in...
