In this chemical reactions worksheet, students fill in 12 blanks with the appropriate terms related to chemical reactions. They also indicate if 4 statements are true or false and match 7 words with their descriptions. Students complete...

Students explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.

Students gain an understanding of scientific methods and use process skills (such as observing, classifying, and predicting) to solve a problem. They develop an understanding of the need for natural preservation.

Students explore the consequences of shrinking habitats and the human impact on wildlife populations. They participate in a game to study the consequences and describe the preservation of animal habitats.

In this resource review worksheet, middle schoolers will review the definition of key vocabulary words and then fill in the blank with the correct term in 10 sentences.

Learners describe how energy can be transformed from one form to another. In this physics lesson, students calculate kinetic and potential energy using mathematical equations. They give real life applications of this lesson.

For this desert adaptations worksheet, students are given a water filled sponge which represents an animal. Students observe their "animal" for a 24 hour period and conserve the water in the sponge as best they can. They measure and...

Students review P2 concepts they learned in previous lessons and explore how to reduce the pollution in their school. They also examine ways to conserve energy.

Seventh graders identify native species of desert vegetation, plan a xeriscape landscape, and recognize the importance of water conservation.

Students create wetland models in pans and use them to experiment to see how plants help slow the flow of runoff water and keep our waterways clean.

In this geology worksheet, students fill in notes using a variety of resources. Students answer questions as it relates to geology, soil erosion, mass movement, and deposition. Students research information about the presented aspects of...

In this power worksheet, 12th graders solve four problems including calculating work done by friction, determining work done by gravity and the calculating the minimum horsepower needed to save a ship that is sinking.

Students analyze a 1936 national park map of Yosemite to distinguish the natural features from the cultural features.

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

After nine lessons and activities about energy, here is the final assessment. The 20-questions include multiple choice, multiple choice with justification, short answer, answer analysis, and labeling diagrams to challenge learners.

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Young chemists perform an experiment to determine if a compound is iron (II) chloride or iron (III) chloride. Then they determine the formula, balance the equation, and answer analysis questions. 

Students explore the Law of Conservation of Matter using effervescent tablets.  In this mass and energy lesson, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will discuss and...

In these environment worksheets, students complete several multiple choice questions that teach them about the Earth's landforms and water.

Students discover the importance of watersheds and how they impact other bodies of water. Using a map, they identify and analyze a watershed in their local area and evaluate the health of the water nearby. In groups, they plan their...

Students complete a unit of lessons on animals and animal conservation. They observe a square meter of ground outside the school, set up a model environment, analyze an owl pellet, grow bread mold, and explore various websites.

Learners use the Internet to research energy efficient appliances. They discover tips on how to save energy in the home and how to read the EnergyGuide labels. They also examine ways to reduce the amount of water that is used.
