Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

Emerging chemists find their calling as they calculate the concentration of hydronium and hydroxide ions and the pH and pOH for several solutions. In some cases, values are given, and in others, actual word problems are written out....

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

Here is an attractive learning exercise that walks chemistry learners through a review of aqueous solutions. There are matching, short answer, and multiple choice questions dealing with boiling and freezing points, precipitate, molality,...

Here is a general chemistry worksheet that incorporates practical applications. Four questions employ critical thinking about solutions, boiling and freezing points, and molar mass. Your class will practice what they learn in class by...

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...

Scholars complete a crossword puzzle in this chemistry worksheet with 20 questions about chemistry concepts like atoms and chemical reactions.

This is an apt assignment for chemistry takers that are studying ionic solutions. Eight questions require problem solving and critical thinking to answer. The first question instructs learners to use a table in the textbook, but you can...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

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.

For 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.

In this chemistry worksheet, students can use the table to observe and name the common types of ions and determine the charges to explain the gain or loss of electrons.

Students apply the science of chemistry to soil and plant relationships. They define diffusion and indicate for which of these nutrient(s) would you expect diffusion to be the most important for movement to the plant root? Pupils...

Learners use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

In this elements and ions instructional activity, students complete a table given an element, the symbol, or the number of subatomic particles and they must complete the rest of the table. The do the same for five ions. They also write...

students research blood's components, and use their math skills to recreate a model of whole blood using commonly found food items.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will be able to determine the number of valence electrons for any element and draw an electron dot diagram for any atom....

In this experiment, students will design and carry out a sequence of chemical reactions for the separation and identification of three metal cations from six unknown samples.

This lesson will define an ion and explain what happens if the number of electrons in an atom changes. It is 1 of 3 in the series titled "Ions."
