Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

Students design their own experiments . They study the scientific method and determine what a testable question is. They distinguish between questions that are testable and those that are not. They identify variables, make and understand...

Students explore why dissolved oxygen must be present for aquatic life to survive. They explain what dissolved means. Students discuss what dissolved oxygen is. They watch as the teacher lights two candles and place a jar over one of...

Where does the pop in pop rocks come from? An engaging activity asks scholars to measure the amount of carbon dioxide in a package of Pop Rocks candy. Learners dissolve the candy in water and use the solubility of CO2 to determine its mass.

Titration experiments don't have to give your high schoolers a stomachache. Study the ways to titrate an acide with a base in an engaging science experiment, which involves creating solutions and performing titrations. Pupils...

Candy is one of my favorite words, and it's an even better word when it relates to science. Yes, candy science can happen when you grow rock candy crystals with your class. The entire process for growing these edible wonders of nature is...

Fifth graders explain how the land changes by developing some "land dances." Working in cooperative groups, each group develops a movement sequence that depicts the vocabulary word they are given. They teach dance to other classmates.

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

Fifth graders explore conductors and insulators. For this science lesson, 5th graders act as electrons moving through a wire. Students break into groups representing conductors and insulators and explore how they work with electrons.

Students polish pennies. In this Science lesson, students experiment with cleaning the oxidation off of pennies with a variety of liquids. Students record their observations.

In this acids and bases worksheet, students compare the properties of acids and bases. Students determine the concentrations required to neutralize solutions. This worksheet has 1 word problem and 14 multiple choice questions.

An educational instructional activity allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson captures the attention of learners as they use what they know about solids, liquids, and gases to create their very own batch of ice cream.

Nature provides density columns in the polar regions that provides food for many animals. Young scientists build their own density columns with water in order to answer analysis questions. Through a slideshow presentation, scholars...

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

Students monitor streams, take stream surveys, collect chemical and macro-invertebrate and stream discharge data. Using a digital camera, students observe the percentage of various types of vegetation on the flood plan, riparian area and...

Students perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.

Students are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...

Students apply the science of chemistry to soil and plant relationships. They define diffusion and indicate for which of these nutrient(s) would you expect diffusion to be the most important for movement to the plant root? Pupils...

Middle schoolers are explained that wastewater treatment plants are regulated as to the quality of water they may discharge into our rivers and canals. They are explained that wastewater treatment plants clean many pollutants out of the...

Students experiment to determine which bottle of soda has more dissolved carbon dioxide. In this solutions instructional activity, students use the scientific method to test the amount of carbon dioxide in bottles of soda. They identify...

Students define and research fossils. For this fossil lesson, students access teacher assigned Internet sites to examine images of fossils. They determine the definition of a fossil and find out how fossils are formed. They also define a...

Students observe an online activity where they see some solids dissolving and some not dissolving. In this dissolving lesson plan, students learn which solids will dissolve, melt, and which won't. They will also see which effects are...
