We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...

Chemical and physical properties give compounds an identity. Learners use the identity of a compound to predict what it is. By performing different tests like solubility, flame, heat, and reactions, individuals attempt to identify an...

Twelve questions about the various calculations of mass and yield are given here.  There is significant practice of molarity calculations and consideration of the reactant and product balance.

Manage your calorie intake with a daily food plan journal. After reviewing a reference sheet with suggested amounts of each food group based on a total calorie pattern, learners can jot down what foods they have eaten during the day as...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Young geologists become familiar with the Karst Topography in the Ozark Mountains. They study how human activity has affected the cave ecosystem. They conduct a simulation in which a large development is proposed in the area, and they...

Facilitate healthy eating habits with this collection of activities. This worksheet, made for 4-H originally, covers nutrition, health, and fitness. Middle schoolers focus on the life skill of making healthy lifestyle choices. They...

Four pages provide plenty of problem solving practice for chemistry whizzes. They answer questions and write electron configurations for ions. They use Lewis dot diagrams to display equations. Covalent bonds are explored. The last half...

In this nomenclature learning exercise, students write the names of covalent and ionic compounds as well as write the formulas when given the names. They also write the names of acids given the formulas and write the formulas when given...

Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

Don't you wish you had the time to type up a study guide for your chemistry class? With this resource, there is no need! A chart comparing the properties of metals and non-metals tops the handout, followed by notes on the reactivity...

Here is an attractive worksheet 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, net...

Hear is a close-up inspection of some of the compounds found in the Centrum Multi-Vitamin. Each slide shows the steps required for forming one. The compounds are as follows: chromium (III) chloride, cupric sulfate, manganese (III)...

A well-balanced meal is crucial to living a healthy lifestyle. Support healthy living with a worksheet that focuses on the amount of sugar we find in our food. The packet begins with an overview, then goes into an activity in...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Lesson 19 in the series of 36 analyzes the element hydrogen and the s-block elements. Through readings, answering questions, and discussion, learners write about and explain their occurrence, physical and chemical properties, and...

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

Students work in groups of two or three, groups are given four unidentified bottled waters in unmarked containers and the chemical characteristics taken from the label on the bottled waters. They devise and carry out a plan to match the...

In this chemistry overview worksheet, students calculated the volume of different gases and liquids given in a word problem. Students had to calculate the molecular mass and write the empirical formula and the molecular formula.

Students investigate the factors which affect corrosion. In this corrosion lesson plan, students experiment with 2 nails, copper wire and magnesium ribbon placed in a petri dish of agar solution, potassium ferricyanate and an indicator....
