Sixth graders use teacher prepared samples of substances. They perform the same observations and complete charts for each substance. After recording and analyzing their results, 6th graders make changes in the recipes to create a better...

Students use a variety of objects to test for ability to "stick" to a magnet. They perform an experiment to see that electricity in circuits can produce light, heat, sound, and magnetic effects. They discover magnets attract and repel...

Learners explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

In this endothermic and exothermic reactions worksheet, students experiment with water and a salt of choice to determine if heat is absorbed or released in the reaction. Students take the temperature of their solution over a 2 minute...

Students observe seeds growth and examine the different parts of the seedling. In this biology activity, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...

Students review properties of matter and discuss how materials change when things are done to them. They observe how materials change as a reaction to temperature by following the procedure to make ice cream and recording the temperature...

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 instructional activity, 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 instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...

For this properties worksheet, students 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...

Students explore the Earth's crust. In this earth science lesson, students participate in 2 activities that demonstrate physical and chemical weathering. Students also play Jeopardy with topics including volcanoes, earthquakes,...

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...
