Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.

Students analyze different types of matter according to its general and specific properties. They design an experiment to classify matter. Students are shown cornflakes and raisins. They are asked what type of substance is each...

Third graders investigate why ice cream does not go through any chemical changes when it is exposed to physical changes. They describe the three states of matter in either written or verbal form. Then students experiment with ice cream...

Young scholars explore the states of water. In this physical science lesson, students use ice and dry ice to observe the changes in the state of matter. Young scholars record the results.

High schoolers examine how scientific theories are developed. In this matter lesson, students explore the basic idea of quantum theory. They create a timeline of scientists, their contributions, and discoveries.

Third graders explore the concept of evaporation as they observe how the water level changes in a cup that is left out. Working in groups they observe physical changes in a group of everyday items. They record the changes in shape, size,...

Second graders observe matter in all 3 states : liquid, solid and gas, in an ice cream soda. In teams, they are given ice and teams compete to be the first to melt their ice. Winner gets the ice cream soda. They draw examples of 3 states...

Students engage in a lesson plan that is concerned with the water cycle and different states of matter. They conduct research using a variety of resources in preparation for taking a quiz. Then students take the quiz in correlation to...

Students solve a mystery using evidence gathered during a science investigation.  In this physical changes lesson, students analyze a note written in marker to determine the physical changes the ink from the pen underwent....

Fourth graders watch the movie "Contact" and write a review. They discuss in their review how scientists deal with technological problems, the movie's connections to the nature of science and how technology affects science. They share...

Third graders observe and reproduce the water cycle in their very own classroom. A simple, yet very effective, demonstration on how water evaporates is observed by the young scientists. They make observations and sketches in their...

Students discuss the three states of matter and how they are affected by temperature. They make ice cream in a bag while observing how temperature change affects the mixture. They discuss why some specimens froze more quickly than others...

High schoolers examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Fourth graders dance with inspiration from wild animals. In this creative movement lesson, 4th graders watch a video clip and then move like an animal might move in their natural surroundings.

Young scholars discover the forms water can take. For this hands-on science lesson, students examine how water can change from a solid to a liquid and then back again.

Your junior highers will learn about which objects are natural and classify objects as abiotic or biotic. Your class will trace human products to their natural resources using matter cycles and then create their own definition of nature.

It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

We have all heard the debate about teaching both theories, but an innovative lesson takes the discussion to a new level. Scholars research and debate Newton's Law of Gravitation versus Einstein's General Theory of...

Advanced chemistry kids experiment with the freezing and boiling points of various aqueous solutions. They also prepare a presentation of the kinetics of solution formation and structure of the matter involved. This resource provides...

If I want to build up my heart, where should I start? Science scholars use statistics in a sports physiology setting during an insightful experiment. Groups measure resting and active heart rates and develop a scatter plot that shows the...

Give science learners nine questions about the biogeography of hydrothermal vents and turn them loose to research this fascinating habitat. Working in cooperative groups, they prepare a report that addresses each of the questions. A...

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson, learners use scientific equipment to collect...
