Young scholars recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Seventh graders observe that heat is produced when two substances are combined. They brainstorm how, and then experiment to find out which of two chemicals created the heat.

In this physical and chemical changes worksheet, students will read 4 different examples of a physical or chemical change and will write in the effect of each of these changes.

In this matter worksheet, students complete a graphic organizer by describing the properties of matter, the changes of matter, and how matter can form mixtures.

Eighth graders practice balancing chemical equations. In this chemistry lesson, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.

Eighth graders analyze physical change in mass. In this chemistry lesson, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with elements,...

In this properties worksheet, learners write the correct term in the spaces beside each definition. Then, students unscramble the letters in the boxes to answer a riddle.

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

Why don't we just capture carbon dioxide in the air and store it somewhere else? A hands-on lesson allows scholars to explore a complex concept. First, they will create a carbonated beverage, and then they will determine...

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Review the 5 branches of chemistry and related terms with this worksheet. The focus of these activities is on terms and definitions. Learners answer questions about the study of chemistry, reasons to study chemistry, and pure and applied...

Young scholars explore the Earth's crust. In this earth science instructional activity, students participate in 2 activities that demonstrate physical and chemical weathering. Young scholars also play Jeopardy with topics including...

Sixth graders discover the difference between weight and mass. In an experiment, they examine the Law of Conservation of Mass in action and discuss if a physical change causes a change in mass. They observe chemical and physical changes...

High schoolers create a foldable to help them remember topics on chemical compounds. In this physical science lesson, students differentiate ionic and covalent compounds. Given certain compounds, they identify whether it's ionic or...

Students make their own candy. In this science lesson plan, students observe how molecules interact with each other in physical changes and observe how the addition of heat can cause molecules to interact and form new molecules in...

Students study bogs. They tour, collect physical, chemical, and biological data and analyze a pristine bog community. Using the data, they draw a map and a cross section of the bog.

Students collect snow samples around their school. They explore the concepts of density and phase change as well as the math skills of measurement and statistics. Students explore the water cycle through an interactive, down loadable...

In this changes in matter learning exercise, learners draw a picture that shows physical and chemical changes. This learning exercise has 7 fill in the blank questions.

Eighth graders explore chemical reactions and their products. They define a chemical reaction and describe the characteristics of a chemical reaction. Students classify chemical reactions.
