Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

Students watch a demonstration to ascertain why a soda can crushed. They make observations and hypothesize about why a soda can crushed and relate the difference in pressure to its affect on objects around us (soda can). Explanation is...

Learners explain that when forces on an object are balanced, the motion of object does not change. They describe how an object changes its motion when forces on it are unbalanced. They plan and conduct a scientific investigation to test...

Young scholars study light and see what emits photons and that light can be separated onto a spectrum.  In this energy and matter lesson students identify gases using a spectrum chart. 

Young scholars discover basic machines and how they make completing work easier. They identify two basic machines, the inclined plane and the lever and the functions of these simple machines.

Fourth graders complete activities to study the sources of energy and forms. In this energy instructional activity, 4th graders discuss the origin of energy and define it. Students participate in several experiments to further study...

Students study how matter changes from solids to liquids or liquids to solids. In this physical science lesson, students discuss heat energy and experiment with heat by changing a candle into a liquid using a hot plate.

For this science worksheet, students read 15 science definitions and determine which science vocabulary word fits  each definition. Students write their answers in the box that precedes each definition.

In this science worksheet, students choose the multiple choice science term that best matches the 15 definitions stated. Students circle their answers.

Students create ice cream in a bag and snow ice cream to study the effects of freezing on foods.  For this ice cream lesson, students understand the effects of freezing on cells.

Learners minerals and how they form. They investigate the classification of minerals according to physical properties. Students watch a video about mineral characteristics. In groups, learners participate in hands-on activities and...

Third graders read, write, and listen to information about the sun and its effects on the Earth.as it relates to its axis, orbit, rotate, and revolution.  In this solar system lesson, 3rd graders examine how the sun...

Students study the properties of the frictional force between two surfaces in contact. They inspect various phenomena in nature where friction plays an important role and demonstrate

Learners explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Students analyze various types of natural disasters and discover techniques man uses to live with nature and to control nature. They are able to identify ways that man has learned to predict natural disasters; identify ways that man has...

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

Students choose a number from one to twelve and tell a number story about it. They listen to the teacher read "Numbers in Art" by Lucy Micklethwait. Students choose three numbers from one to twelve and view works of art while looking for...

Second graders explain the definition of hail and sleet. In this precipitation lesson, 2nd graders discuss when hail and sleet fall and the results of hail falling.

Students explore schools during the Colonial period. In this American history lesson, students participate in a simulation of school days in Colonial America. Students visit a museum and use the schoolhouse as a setting for their...

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

Students identify the different parts and functions of the cardiovascular system. In this forensics lesson, students collect and analyze evidence on a fictional crime. They describe different causes of cardiac arrest.

Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur.  In this matter lesson students divide into groups and complete a lab experiment. 

Students explore the density of soap. In this science instructional activity, students conduct an experiment to find which types of soap will float. Students make a hypothesis and record their observations.

In this chemistry instructional activity, students find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.
