Pupils compare and contrast exothermic and endothermic reactions. In this chemistry lesson, students perform experiments to determine whether heat was released or absorbed in a reaction. They share their observations in class.

Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Carbon dioxide is a very important gas; it is present in the air, used in cooking, and supports plant and animal life. Scholars investigate the properties of carbon dioxide with three different activities. They experience a color change,...

Students conduct a series of experiments in which they explore chemical reactions. They detect chemical changes by observing how physical properties change when two different chemicals are combined. They list and describe the reactants...

In this chemical reactions worksheet, students fill in 12 blanks with the appropriate terms related to chemical reactions. They also indicate if 4 statements are true or false and match 7 words with their descriptions. Students complete...

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...

Introduce physical science learners to the forms of energy using this PowerPoint. The concluding slides present scenarios for discussing the transfer of energy from one form to another. Informative text is crisp and attractive, but the...

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Introduce the topic of puberty. This presentation breaks it down into bite-sized pieces: physical changes, mental changes, emotional changes, and social changes. There is some basic information in each section, which hopefully opens it...

Pupils study the difference between chemical and physical weathering. They explore the effects of climate on the weathering process.

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

In this chemistry activity, students answer 73 fill in the blanks and multiple choice questions on the structure of matter and properties of elements in the periodic table.

Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur.  In this matter lesson students divide into groups and complete a lab experiment. 

Pupils differentiate physical and chemical changes. In this chemistry lesson, students give examples of each type of change. They take the review quiz at the end of the lesson.

Third graders investigate why ice cream does not go through any chemical changes when it is exposed to physical changes. They describe the three states of matter in either written or verbal form. Then students experiment with ice cream...

Students create illustrated plastic plate designs depicting a physical, chemical, or biological change of some kind after investigating the artwork of porcelain artist Kataro Shirayamadani.

Students investigate various chemical reactions when creating mixtures in ziplock baggies. For this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Students observe and analyze weathering. In this earth science lesson, students demonstrate physical and chemical weathering in two experiments, then write questions for a class Jeopardy game.

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

Learners explore the properties of matter.  In this cross curriculum three states of matter science lesson, students listen to the poem "Eighteen Flavors" by Shel Silverstein, and predict what will happen if listed ingredients are...
