Students investigate what is wrong with the Rutherford atomic model. In this chemistry lesson, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how the atomic model...

Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...

Fifth graders build objects using various materials. They estimate the weight of the object using individual building pieces. Then they weigh the actual object and then tear it apart and weigh the pieces. They compare the two weights.

Eighth graders determine the density of a sinker by first finding the mass and then the volume using a graduated cylinder. Students must write the procedure they use to find the volume of the sinker then apply their data to follow-up...

Students participate in a small group read aloud of the short story, "Cerium" by Primo Levi. They answer several questions about the story and then relate the reading to a lecture on Kinetic theory. After the lecture they apply the...

Students investigate the effects of air pollution. In this environmental lesson, students discuss the causes of air pollution and identify how transportation has an effect on the air quality. Students identify other alternatives to driving.

High schoolers recognize the benefits of ethanol and study photosynthesis.  For this ethanol lesson students complete an experiment that shows the procedure that starch can be hydrolyzed by salivary amylase. 

Students examine ways positive and negative charges are attracted and repelled by watching teacher demonstrations, and complete activity sheet related to classroom demonstration activities to prove proficiency of knowledge of...

After some online instruction, chemistry aces use their creative abilities to produce a poster describing the photoelectric effect and one type of imaging technology that uses electromagnetic radiation. This simple, straightforward...

Students describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students observe...

Students identify colors created by mixing primary colors and describe the process. They then design a book using the colors of a given season entitled "Colors of the Season".

Students investigate birds and complete a variety of bird-themed activities. They read books and observe birds noting their physical characteristics, development and life cycle stages.

Students minerals and how they form. They investigate the classification of minerals according to physical properties. Students watch a video about mineral characteristics. In groups, students participate in hands-on activities and...

Students review atomic structure and then participate in a activity in which they categorize several "elements" into some form of order based on their properties. They discuss the trends they see. They also practice several electron...

Young scholars estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.

Students predict whether objects will sink or float in water. They classify objects as sinking or floating in water. Students identify and explain similarities between objects that sink and float.

High schoolers apply the ideal gas law and Dalton's Law of Partial Pressure to develop an experiment which determine the molar mass of butane from disposable lighters. In small groups, they develop a procedure and have it approved...

Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...

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

Students relate chemistry to an object they use everyday. They research information related to chemistry and create their own webpage. They are to keep their page up to date as new observations are taken.

Third graders are presented with the problem of: Do all liquids evaporate at the same rate? The lesson contains adequate background information for the teacher. They participate in a lab experiment in order to test the scientific...

Tenth graders are provided with a piece of paper such as index, art, construction, or computer coating it with a universal indicator. They use cotton swabs HCl and NaOH to draw a picture repeating the same process using lemon juice and...

Learners review the characteristics of acids and bases. They examine the structure of an amino group and compare amines to ammonia. They work together to develop the concent of polymerization.
