Although the points given on these slides are valid, the visual accessibility is poor. Consequently, many viewers would be distracted or entirely unable to view the presentation.  The content is a review of microorganisms and their...

In this science instructional activity, students apply themselves to the acquisition of new vocabulary while solving the crossword puzzle.

Eighth graders identify the three main types of chemical bonds. In this chemistry activity, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.

Tenth graders examine chemical reactions.  In this chemistry lesson students choose an investigation that they wish to perform based on their interest.

Young scholars develop an awareness of the use of Vitamin C in helping our environment and gain exposure to chemical procedures and techniques. Students analyze and interpret data by keeping a data sheet and making a bar graph.

Students measure in metric units and use a stopwatch, calculator. They collect data with minimal instructions after the initial pre-activity briefing, then record data in the data sheets provided.

Eighth graders discuss the different types of ecosystem. For this earth science lesson, 8th graders explain the benefits and harm of fire. They research articles about bush fires or controlled burn instance and share it with the class.

Tenth graders test their saliva for enzyme activity. In this enzyme activity, 10th graders conduct an experiment to test the enzymatic activity of their saliva. They relate the lack of certain digestive enzymes with alcoholism.

Learners investigate the chemistry of coal. This lesson serves as a review of conservation of mass, simple reactions and equation balancing. During the lesson, students research chemical components of coal, as well as environmental...

In this chemistry review instructional activity, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

Ninth graders explore ways water moves through various reservoirs on Earth, examine how human activities change water cycle, investigate substances present in water that indicate human activity, and discuss how understanding water cycle...

In this conservation of mass activity, students experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products after the experiment...

Students examine a crushed rock and sort the minerals they find in that rock by color and other properties.

Students investigate the differentiation of magma to form different minerals present in a rock. By using the model proposed by Bowen, they determine the depth, temperature, and composition of magma. Students explain why some minerals...

Students compare the energy value of traditional foods eaten by indigenous people with those of modern commercial foods. They use a calorimeter to measure and calculate the amount of stored energy in various food types, and identify the...

Students experiment with mixtures of matter. In this matter instructional activity, students investigate which liquids form a solution when mixed together and which do not. Students also identify which solids can be separated from matter.

Instructions for building a simple electromagnetic motor are provided for the teacher. Aside from some sketchy background information and a list of content standards to be met, that is about all you will find in this resource. The motor...

Mutation and auxotrophs are discussed. Next, the details of RNA transcription and how enzymes can control splicing and introns are given.

In this science review for grade 5 (5.2) activity, 5th graders answer 25 earth science questions in a standardized test format, including reading maps and diagrams.

Hurricanes, typhoons, and tropical cyclones are the same type of storm, but their names change based on where they happen. Scholars use a computer simulation to learn about hurricanes. Then they hypothesize ideas to prevent hurricanes...

Students collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess the...

Students complete a Webquest which investigates the chemistry in items such as shampoo. They research the Internet, perform a lab experiment, and write a scientific lab report with their findings. Upon completion of the activities, the...

Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...

Learners identify the characteristics and composition of emulsions. In this chemistry lesson, students classify household products according to emulsion type. They explain how to make the best emulsion.
