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.

High schoolers discuss transition metals, their properties, and where they are located on the periodic table as well as why transition metals are ideal for coins. After discussion, they conduct an experiment using copper in the form of...

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

Students study the rhinoceros and how the species has survived for so long.  In this rhino lesson students create graphs and research what is being done to protect the rhino.

Students investigate patterns of immigration in the US while comparing and contrasting the ideas of citizenship and non-citizenship. They decide how education plays a role in citizenship.

In this rate worksheet, students draw and label given situations, determine the rates and the relationship between them. This two-page worksheet contains 7 multi-step problems.

Most of this lesson is spent working on the "Bathymetry Worksheet." It includes a graph of the changes in sea level over the past 150,000 years and a bathymetric map of changes in an imaginary coastline over time. Participants answer...

Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a...

Students explain how melting glaciers affect global warming. For this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Learners investigate the differentiation of magma to form different minerals present in a rock. By using the model proposed by Bowen, they determine the depth, temperature, and composition of magma. Students explain why some minerals...

Students observe the chemical reaction that occurs when salt is put on ice, and use the energy that is released to make ice cream.

In this properties of matter worksheet, students answer 6 questions related to matter. They classify and categorize given statements as chemical or physical properties, they identify chemical and physical changes and they find the...

Students study the concept of ice energy. In this ice energy lesson, students observe what happens when salt is sprinkled on a piece of ice before following a recipe to make two types of ice cream. They note the difference in the two...

Young scholars investigate how salt affects the state of ice. In this ice cream making instructional activity, students change the freezing temperature by adding salt and observing the results. Young scholars use experimentation and...

Students identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.

Students synthesize Indole-3-Acetic acid from 3-indolylacetonitrile. In this biochemistry lesson, students determine the effect of different concentrations of IAA on lima beans. They explain how hormones help in plant development.

In this matter worksheet, students answer ten questions about matter including the phase of matter, mixtures and how they are different from compounds, the physical and chemical properties of matter and the difference between homogeneous...

In this matter learning exercise, students compare the different types of matter, including the states of matter. Students review the metric system. This learning exercise has 12 matching, 18 fill in the blank, and 4 short answer questions.

In this chemistry review worksheet, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

Seventh graders investigate the particulate level of solids, liquids, and gases. They examine how the particle method show the interplay between scientific theories and evidence.

In this subject and predicate agreements worksheet, students match the noun with the verb to complete and write sentences. Students write 12 answers.

Students explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

In this chemical change worksheet, learners conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...
