Eighth graders conduct an experiment that analyzes the physical and chemical characteristics of various water samples. They discuss the procedures and safety concerns for the water test, and test their water samples to determine if they...

Students work in groups of 4-6 for the experiment/activity part of this exercise. They base their explanation on what they observed. Students observe how substances react chemically in characteristic ways with other substances to form...

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...

Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...

Young scholars describe how elements are arranged on the periodic table. They compare metals, nonmetals, and metalloids based on their properties and on their locations in the periodic table. Students describe the differences between a...

Eighth graders are introduced to the topic of Environmental Chemistry. In groups, they review the steps within the scientific method and develop their own hypothesis and design an experiment. They solve equations related to the...

Students demonstrate comprehension of the physical characteristics of the Dead Sea region and its connection to the Red Sea and the African Great Rift Valley. They are given students the opportunity to understand the role of plate...

Students investigate the properties of polymers. In this chemistry lesson, students explain the importance of energy sources. They produce a bioplastic from the lab and evaluate its structural integrity.

Young scholars explore what amino acids are, their history and how they are used in technology.  In this protein lesson students identify the properties of proteins and amino acids.

Young scholars list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their...

In this atoms worksheet, students will review the characteristics of elements, atoms, and isotopes. Then students will compare the difference between ionic and covalent bonds. Finally, students will balance a chemical equation. This...

In this chemical reactions worksheet, students determine the reaction rate for various reactions, write balanced equations, create graphs showing the reaction over time, and calculate the activation energy and potential energy. This...

Students explore the properties of water and how it changes states. In this kindergarten to 2nd grade science lesson plan, students pair a hands-on science activity with two suggested books. This inquiry lesson plan...

As part of a unit investigating the dissolving of M&Ms® candy coating, this lesson examines whether or not the different colors combine. There are no new concepts revealed in this particular lesson, but learners will see that the...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Students observe the effect of various chemicals on coal. Using coal, laundry bluing, water, salt, and ammonia, they observe crystal formations after a period of a few hours, and discuss their observations.

Students examine the effects of heating on various crystals. They formulate and revise scientific explanations and models using logic and evidence. Students work individually during this experiment.

Young scholars compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...

Students collect data and make observations on how given element samples respond to the field of a magnet and they calculate the density of the samples by finding the mass and volume.

In this science:  acid base quiz worksheet, students answer 20 true or false questions, not interactively, about acids and bases, then scroll down to check their answers.

Students identify the periodic table trends and predict material properties. They also design and conduct simple experiments and test material properties. Finally, students compare and contrast material properties and that chemical...

Students use a digital atlas to explore the effects of water on landscapes. They view view pictures and complete worksheets to study the properties of water. Students study the water cycle and the chemical role it plays in living cells.

Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.

Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They also identify and interpret how to use the periodic table to identify metals, semimetals, nonmetals, and...
