What happens when solids are added to liquids? After reading an informative paragraph about solutions, learners answer six true/false questions regarding solutions, and what substances will dissolve into liquids they are mixed with. A...

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

Some of kids' favorite toys are the products of science experiments. Scholars follow precise measurements to mix and create their own slime and Play-Doh. They observe the changing textures and the chemical reactions throughout the...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson plan includes a range of learning experiences, from experimenting with the rate at which ice...

In this chemical reaction worksheet, students investigate the reaction that makes curds and whey. They mix milk and vinegar and run it through cheesecloth to collect the solid. Students make observations, read about curds and whey, and...

In this states of matter activity, students are given a summary of the particle arrangement, the motion of particles, the properties of particles, and models of particles in solids, liquids, and gases. Melting, evaporating, boiling,...

In this covalent and ionic substances instructional activity, students use the internet to find information about the characteristics of covalent and ionic substance and explain what causes the differences in these types of substances.

In this chemistry review activity, 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.

In this solubility and intermolecular force instructional activity, high schoolers are given 26 clues about forces between molecules such as hydrogen bonds and London forces and about solubility of solutions.

In this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

For this liquids and gases worksheet, students review 9 vocabulary terms associated with liquids and gases by completing a crossword puzzle.

Extensive notes on foundational chemistry concepts make up this resource. It summarizes the properties of matter, the periodic table, chemical nomenclature, and general chemical bonding. Design a set reading comprehension questions to go...

Third and fourth graders engage with a worksheet designed to help them differentiate between melting and dissolving. After reading an informative paragraph about the two actions, they consider four scenarios, and choose whether they...

In this Earth's environment worksheet, students complete a crossword puzzle given 35 clues about a variety of topics related to our Earth. Topics include ecosystems, precipitation, biomes, energy transfer, soil, weathering and rocks.

Mixing substances together causes their properties to change. This resource illustrates that concept for fifth graders by having them consider four questions that have to do with buoyancy and boiling point. Learners begin to understand...

In this earth's environment worksheet, learners use the 20 clues and their problem solving skills to correctly complete the crossword puzzle.

In this review of general science worksheet, students classify examples of matter as mixtures or substances, homogeneous or heterogeneous mixtures, or elements or compounds. Students also convert several examples using the standard...

In this earth science worksheet, students read about the characteristics of the Earth's layers such as the mantle, core, and crust. They answer 10 mixed type questions using the online application.

In this solubility worksheet, students conduct an experiment to see how temperature effects the solubility of salt in water. Students record their data in a chart and then graph the results. Then students complete 2 short answer questions.

For this preparation of triiodomethane learning exercise, students use propanone to prepare triiodomethane. Students use filtration and recrystallization to produce the product. They determine the melting point using a melting point...

In this safety procedures worksheet, students answer questions about eye safety, broken glass safety, lab area safety, chemical safety, fire safety and chemical disposal safety.
