Many periodic tables mention specific heat, but how do scientists determine those numbers? Scholars attempt to find the specific heat of a metallic element by using a calorimeter. Three experimental trials ensure accuracy, and analysis...

Melting and burning might seem like opposites, but both exist as common examples of exothermic reactions. Scholars work with three different exothermic chemical reactions to determine the enthalpy changes. They measure and mix chemicals,...

Humans tend to huddle together when cold and move around more when warm, but do gas particles follow the same pattern? Scholars use a temperature probe, a pressure sensor, and air to study the relationship between temperature and gas...

Do your high school scientists know the four methods scientists use to communicate information? A simple experiment discovering the relationship between gas pressure and volume allows pupils to practice all four. After completing the...

As the most abundant element on the earth, hydrogen requires no replacement. Yet scholars learn to replace hydrogen with a metal to liberate the hydrogen gas. A simple procedure and data table include the necessary information and...

As the title suggests, this is a simply summary of fossil fuels. There are no questions to answer or problems to solve, just notes about fossil fuels. The notes cover how fossil fuels are formed, how we extract it, what humans use it...

A 17-page practice final exam for a college-level introductory biology course is contained in this resource. Matching and short answer questions cover every topic that you would expect to teach during an advanced biology course including...

To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...

Learners wxplore acids and indicators by watching a demostration in which "magic" ink appears. They duplicate the demonstration by writing magic messages using phenolphthalein solution and painting the message with vinegar to show it.

For this atoms worksheet, students complete a graphic organizer comparing the properties of the 3 subatomic particles. Then students complete 1 short answer question.

In this measurements instructional activity, students fill in 10 blanks, determine if statements are true or false, match 6 terms with the appropriate definitions, and solve 2 problems. Topics include converting to scientific notation,...

In this conversion worksheet, students fill in 10 blanks, determine if 5 statements are true or false, and match 3 terms with the appropriate definitions. Students answer questions about conversions factors and their equivalences,...

In this bonding worksheet, students fill in 8 blanks with the appropriate terms about theories of bonding, they determine if 6 statements are true or false, they match 5 terms with their meanings and they solve 1 problem related to...

In this classification of changes instructional activity, students identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the...

College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...

Students examine specific skills in assessing water quality from a holistic approach. They assess the health of a local watershed and identify problems in the local watershed and suggest remediation.

Students demonstrate Graham's Law by observing a gaseous diffusion. After a lecture/demo, students perform an experiment then complete a write up activity which is imbedded in this plan to reinforce what they have observed during the...

Students comrehend that water displacement is a simple way to measure the volume of a solid object. They pour water into a graduated cylinder or measuring cup and its volume is read and recorded. Pupils the volume of an object by...

Young scholars explore matter through the concept of displacement. They perforrm an inquiry experiment with a glass, paper and a bucket to demonstrate that gases take up space.

Students use sight, touch and chemical test kits to evaluate and classify soil types. They determine the organic content, soil pH, conduct visual analysis and nutrient tests of a variety of soil samples from various sources.

Students distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. Pupils also...

In this elements worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with the 25 clues given.

In this chemical compounds worksheet, students draw and correct Lewis structure for the given compounds or ions. Students draw the resonance structure if applicable. This worksheet has 8 problems to solve.

In this chemical compounds worksheet, students draw the Lewis structure, draw the resonance structure, and give the geometry of the underlined atom. This worksheet has 8 problems to solve.
