In this volumetric analysis instructional activity, learners experimented with a known amount of hydrochloric acid to determine the relative molecular mass of an unknown group 1 carbonate. Students use volumetric analysis to determine...

Public health trainees read and write a summary of the article, "A Whiff of Danger". The article is not available through the link, but can be found on the National Center for Biotechnology Information website. After summarizing,...

For this periodic table worksheet, students review atomic mass, molar mass, and percent composition of compounds. Then students complete 4 problems.

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

In this formulas and equations activity, chemistry apprentices write the chemical formulas given the names. They calculate percent composition, balance equations, and calculate the mass of a substance present in a fertilizer. This is a...

The periodic table of elements is a vital tool for all chemistry apprentices and professionals alike. Here is a chance for your beginning chemists to assess their understanding of the periodic table. They list element names, symbols,...

In this moles worksheet, students review solubility, moles of solute, molar mass, and colligative properties. This worksheet has 10multiple choice questions and 11 problems to solve.

High schoolers record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

In this periodic table worksheet, students complete a table of elements with their atomic number, atomic mass and symbol. They classify elements by their group name and distinguish between metals, nonmetals, and semi-metals. They also...

Chemistry neophytes use a temperature probe to assess the change as five different liquids evaporate. The implantation section suggests that they take readings every five seconds for a total of four minutes. They graph the data, look up...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

In this chemistry worksheet, students locate and identify various vocabulary terms related to chemistry. There are nine words/phrases located in the puzzle to find.

Students experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion lesson, students demonstrate pressure as a force per area. They conduct an experiment to show the relationship...

In this idea gas learning exercise, students review Dalton's law of partial pressures, vapor pressure, relative humidity, and dew point. Students answer 3 problems.

Young scientists get to the heart of the matter as they complete this worksheet on the properties of solids, liquids, and gases.

How many planets can you name? Did you get all 13 in our solar system, including the dwarf planets, or were you surprised when you read there are 13 planets? The lesson helps scholars understand the scale of the universe including the...

Students explore chemical solutions. In this chemistry lesson plan, students investigate the relationship between three related experiments about solutions. Students determine variables that affect the chemical concentration of each...

Beginning chemists examine a collection of elements and compounds as they are introduced to the periodic table. The lesson plan is not cohesive and does not provide detailed instructions on how to teach it. However, it does includes a...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

Should Pluto be considered a planet or a dwarf planet? Scholars research planets in our solar system to understand their similarities and differences. It also includes memory activities related to the order of the planets. 

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.
