Young scholars explore density, mixture and solutions in a reaction. In this chemistry lesson, students create their own chap-stick using ingredients they analyze for their chemical contents. They discuss measuring skills, melting points...

For this percent of iron in lawnsand learning exercise, learners perform a titration of lawnsand using potassium manganate(VII) solution and determine the number of moles of iron in the sample. Students use the number of moles to find...

In this heat transfer and phase change worksheet, learners experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...

Here is a great opportunity to introduce your mathematicians to a food they may never have heard of, quinoa. It may help to show a short video on quinoa, or make some quinoa for the class to try. Once they get over how to say quinoa,...

Students participate in an experiment to demonstrate how mixing certain chemicals together can change the consistency of both chemicals. Glue, water, and borax are used to create a slime-like substance which is examined to determine how...

In this chemical reactions worksheet, students calculate the volume or pressure for different gases. Students determine the effect of different stimuli on the rate of a chemical reaction. This worksheet has 1 short answer, 10 fill in the...

Young scholars test for the presence of enzymes in fruit and the specificity of those enzymes. They identify the susceptibility of enzymes to certain environmental factors such as temperature and pH in the enzymes environment.

In this solutions worksheet, students determine the pH or molar solubility of different solutions. Students state is the mixture given forms a buffer. This worksheet has 20 problems to solve.

Students examine the importance of applying the scientific knowledge of elements, mixtures, and compounds to manufacture consumer goods and conduct civil operations, such as water purification. They also practice categorizing examples...

Learners design and conduct an experiment to determine which of three solutions contain starch or sugar. This task assess students' ability to make simple observations, design simple experiments, utilize indicators, and make generalized...

In this chemistry instructional activity, students find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.

In this minerals worksheet, students will review the four physical characteristics used to identify a mineral: streak, color, size, and hardness. Students will also understand the Mohs Hardness Scale. This worksheet has thirteen short...

Students will make a lava lamp. For this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

Students develop a comprehension of parts per million as a concept. They work in teams to create successive dilutions of a solution to reach a parts-per-million concentration. Students list what they think the atmosphere is made of. They...

In this concentration changes and equilibrium worksheet, learners experiment with iron (III) ions and thiocyanate ions to observe the effects of concentration on the equilibrium of solutions. High schoolers observe their mixtures,...

Students design an appropriate and usable storyboard and then create a claymation video. They take digital photographs frame by frame, then assemble the stop-motion movie using video software.

Students complete experiments with three different bubble solutions to determine which one creates the largest bubbles. Before conducting the experiments, they discuss the ingredients in each solution, and make predictions on which will...

Students investigate the coefficients in a chemical equation and their relation to moles. In this moles and coefficients lesson plan, students perform a single replacement reaction of copper (II) sulfate and zinc and find the ratio of...

Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...

Tidy slides and lecture notes for each are included in this presentation on alloys. Instruction begins with the molecular arrangement of a pure element, gold, and progresses to a few example alloys: brass, steel, and nitinol. This...

Students explore acids, bases, and indicators. They observe the various colors of an acid-base indicator solution and the neutralization of an acidic solution by an antacid.

Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.

Third graders use the scientific method as they separate the colors used in ink. For this chromatography lesson, the teacher introduces students to how chromatography is used in several careers, then students perform an experiment to...
