Students identify principles behind acid-base reactions. They predict factors that may affect an acid-base reaction. Students identify questions and concepts that guide scientific investigations.

Ninth graders are presented with a problem that has to be solved. The scenario is a mystery that is purely hypothetical. This does draw on the knowledge of previous lessons. The lesson plan contains background knowledge explaining the...

In this matter worksheet, students review the structure of matter including elements, atoms, and the periodic table. This worksheet is a graphic organizer.

Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

Vocabulary that is essential to this topic is introduced and defined at the start of this slide show. The following slides help students understand proteins and their use and involvement in everyday substances. Great diagrams help your...

In this identifying graphic organizers and their texts worksheet, students observe chronological, compare & contrast, sequence, cause & effect, and problem & solution graphic organizers, read short passages, and match them....

More extensive than just a general overview of digestion and reactions, this slide show gives information about all areas of enzyme function.  Topics like the chemistry behind efficiency of enzymes, factors that affect speed of...

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.

Young scholars observe crystals and their shapes and formation. In this crystal formation lesson, the teacher prepares crystal gardens for the students to observe, then the class finds examples of crystals in nature and observe a teacher...

Students analyze various beverages to determine vitamin C content. Students research diseases resulting from vitamin C deficiencies and identify countries most affected.

"Self-guided Computer Activity" simply means that young chemists read through the slides and take notes about atoms along the way. There is an abundance of text on each slide, making this a comprehensive introduction to atomic structure....

Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them. 

Time to show off what they've learned! The final lesson in the series of six asks young scholars to process their learning from the previous lessons. They identify possible elements of the sun as well as a possible origin.

Ninth graders describe that matter is made of minute particles called atoms, explain structure and properties of atoms, classify chemicals, locate chemicals on the periodic table, and play Jeopardy.

Students distinguish waves from matter, differentiate between transverse and longitudinal waves, use sine curves as representations of transverse waves, label characteristic properties of waves, diagram transverse waves having specific...

Students analyze the amount of space required to pack round objects. In this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

Fourth graders investigate air pollution. In this air pollution lesson plan, 4th graders test the air quality by using a block of wood and petroleum jelly. Students investigate the pollutants on the wooden block.

Students read and discuss Boyle's Mechanical Philosophy and his rejection of Aristotle's theory of "Forms and Qualities." They answer a given set of questions and discuss these with the class.

Students identify several properties of water as a universal substance, describe the composition of several complex color mixtures and separate the components of dye using chromatographic technique.

You can't b. cereus until you see this activity! Young microbiologists learn to prepare deep well slides, observe two types of microorganisms, and compare and contrast their physical characteristics in this interactive and lively activity.

Feel the pull of science! The final installment of this 18-part series is an application of everything learned in the previous high school lessons. Scholars are given a magnetic field map and must propose an arrangement of magnets that...
