Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

In this mass spectrometer worksheet, students read about how a mass spectrometer determines the elements in gases around Earth. Students answer 3 questions and identify the elements in a graph found by a mass spectrometer.

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...

In this compounds worksheet, students write the polyatomic ionic compound formulas or the compound names. This worksheet has 29 problems to solve.

Students investigate chemical reactions. In this chemistry lesson plan, students burn magnesium and record the mass. Students list five chemical reactions they see everyday.

Students study the different types of metals.  In this investigative instructional activity students watch a demonstration on the effects of temperature on atoms and take a tour through baone matter.

Students investigate the components of chlorophyll. They use paper chromatography to separate the many pigments of chlorophyll from one another.

Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity,...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

In this chemistry worksheet, students find the outcomes necessary for the oxidation reduction reactions. The sheet includes background information.

There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

Students determine that the rate of reaction is affected by temperature, surface area, concentration of reagent, and addition of a catalyst or inhibitor. They observe that on December 3rd, 1984, 8000 people died when the chemical plant...

In this chemical compounds worksheet, students review the different types of bonding, define the octet rule, and draw Lewis structures (electron-dot diagrams) for given compounds. This worksheet has 7 fill in the blank, 5 short answer...

Learners observe crystals under the microscope. In this science lesson, students compare how the crystal look like using their eyes, hand lens and microscope. They identify the type of crystal based on the amount of light they allow to...

Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.
