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.

Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

High schoolers examine hydrothermal vents. In this ocean lesson, students identify changes in physical and chemical properties of sea water caused by hydrothermal vents.

In this Dalton worksheet, learners read about John Dalton and his contributions to understanding the atom. Students are given sample data for Dalton's experiments and they answer questions about the data in his experiments.

In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.

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.

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 collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

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.

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...

Students examine how some natural substances are polymers.  In this polymer lesson students complete a lab and give examples of a physical change. 

Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.

For this matter worksheet, students answer ten questions about matter including the phase of matter, mixtures and how they are different from compounds, the physical and chemical properties of matter and the difference between...

Students define temperature and heat, distinguish between temperature and heat flow, calculate amount of heat energy released or absorbed in chemical process, and design procedure, through experimentation, to gather and evaluate data to...

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...

Students describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.

Students observe a demonstration in which a bottle containing a colorless solution is mixed, turns blue, then becomes colorless again. They record observations, form and discuss hypotheses, and draw a conclusion based on the evidence.

Students answer 71 questions about a variety of topics in biology. In this biology trivia lesson plan, students use the internet to find the answer to questions about the systems of the body, their structures and functions, the different...

Ninth graders explain the purpose of MPA's. In this biology instructional activity, 9th graders identify MPA's in Southern California. They simulate coastal sampling using candy from two buckets. Students analyze their results and share...

Tenth graders determine the cause of an algal bloom in a classroom aquarium. Students analyze the situation and present a solution to the problem in the given time frame after researching and conducting experiments. Solutions are...

Students engage in a laboratory lesson in order to increase understanding of the impact of phosphates at the chemical and ecological levels. The lab exercise is completed with the goal of getting them to predict the outcomes and future...

Third graders act as scientists. In this property discovery lesson, 3rd graders explore the substance "Oobleck" (cornstarch, water, food coloring). They work in groups to investigate the substance and make observations as a scientist...

Middle schoolers research on the history of adhesives. In this science lesson, students select one test to use in finding the stickiness of adhesives. They collect data and formulate a conclusion.

Students examine mixtures and solution properties by making a borax polymer. In this chemical reactions instructional activity, students make a putty out of borax solution mixed to create a polymer.
