Learners engage in a laboratory lesson plan 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...

In this science worksheet, students read about chemical changes. Students also answer 3 comprehension questions about the reading.

Students analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies of the...

Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe water evaporating from an open container and water evaporating and condensing in a closed container. The students assess that a...

In this chemistry review activity, students read about atoms and the periodic table and they complete a chart using the periodic table to find the atomic number, atomic mass and group of given elements. Students answer 5 questions about...

Students explore the diet of insects. In this "insects" biology lesson, students take a nature walk and collect various natural materials they think may be eaten by insects. Students sort and classify these materials into three diet...

Students identify animals in ecosystem depicted on 16th Century ceramic basin and classify them as herbivores, carnivores, or omnivores based on physical characteristics and prior knowledge, determine which life forms in ecosystem are...

Young scholars 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...

Students observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board from...

Fifth graders design an experiment in which they separate mixtures. In this mixtures instructional activity, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an...

Students examine the concept of magnetism by doing several activities using magnets and compasses. They explore poles and polar repulsion and attraction.

Students explore the generation of magnetic fields from currents in wires and measure the magnetic field directions. They measure magnetic fields in their own environment. They also examine how moving magnetic fields can create currents.

Students examine the characteristics of a tornado. They practice using new vocabulary and participate in a question and answer session. They use the internet to gather more specific information.

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...

Middle schoolers incorporate different disciplines into this lesson. In this science lesson, students investigate the use of communicating without words, and how it is different than communicating with words. They discuss the pros and...

Students investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute...

Third graders explore the work of Daniel Bernoulli through experiment and background information.  In this Bernoulli lesson, 3rd graders participate in air pressure experiments. Students record their observations of the...

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Second graders examine the characteristics of animals who live in a pond environment. In groups, they describe the various stages in the life of a frog and identify the characteristics of other pond animals. Using this information,...

Learners predict, observe, and explain the details of salt as they view it under a variety of magnifications. They observe salt with the naked eye, and then under a hand lens, microscope, and the electron microscope.

Learners explore the role of women in ancient Mesopotamia. Several excerpts from the Mesopotamian cuneiform tablets and artifacts are analyzed to determine the treatment, rights, and powers of women in this era.

Students examine the differences between a virus and a bacteriophage. They explore various websites, identify the parts of a virus and a bacteriophage, and construct a model of a virus or bacteriophage.

Fourth graders learn how to classify animals. In this invertebrates instructional activity, 4th graders discuss how we classify thinks into groups and move into a discussion about classifying animals. Students learn about the differences...

Ninth graders discover the reasoning behind spraying water on fruit and seedlings in preparation for hard freezes. In this conceptual physics lesson, 9th graders conduct an experiment to measure the heat released when water goes from a...
