In this air instructional activity, students will choose the correct definition for atmosphere, troposphere, stratosphere, and pollutant. Then students will complete a concept map showing what components make up air. This instructional...

Students discover how engineers use sound energy. They participate in hands-on activities in which they discover how we know sound exists. They identify different pitches and frequencies as well.

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

First graders break into groups of five students and are given 15 different objects and 3 posters. They group the objects into 3 different families with all the objects in each category placed on one of the posters. They choose whatever...

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Third graders rotate between three property stations, the solid station, the gas station, and the liquid station. They experiment with each activity until the teacher gives the signal to change.

Fourth graders experiment with the viscosity of different liquids. They use a stopwatch to time the a steel ball as it drops through different liquids.

Students examine how soil holds together and what the effect of particle size and water content is on soil.  In this engineering lesson students complete a lab, record their observations and discuss what they learned. 

Young scholars predict the common classroom items, such as paper clips, chalk, keys, or erasers, that will be good conductors in a circuit. They build circuits using a variety of circuit diagrams to test their predictions.

First graders investigate the different stages of the water cycle. They conduct Internet research and complete a water cycle WebQuest. Students identify what happens at each stage of the water cycle, and write about each stage in their...

In this scientific method worksheet, students read about the steps of the scientific method, ways to measure mass and volume and how to read a meniscus. Students use the scientific method to determine if an object is a liquid or a solid...

Students explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...

In this ideal gas learning exercise, learners read about the conditions necessary for an ideal gas to exist. They also read about the deviations from the ideal gas situation and answer four questions about ideal gases.

In this solvent worksheet, students explore why water is considered a universal solvent. Students explore what can change dissolving rates. This worksheet has 8 matching, 3 short answer, 11 fill in the blank, and 4 problems to solve.

Eighth graders examine different solutions.  In this solution material instructional activity students complete a lab activity and several worksheets. 

In this chemical reactions worksheet, students determine the reaction rate for various reactions, write balanced equations, create graphs showing the reaction over time, and calculate the activation energy and potential energy. This...

Students are introduced to the concept of friction. Using that information, they discover ways in which friction can be useful. They participate in different activities to see fricition in action. They complete a grid worksheet and...

Students compare the properties of rocks. They identify objects made of rocky materials such as walls, sidewalks, etc. Students describe and group rocks based on their characteristics.

Learners investigate different forces and draw arrows to signify specific directions of force. Students are then shown a brick and they are asked to draw a diagram which will include labels for the forces that are acting on the brick....

Students identify and explain the parts of a flower and their role in the life cycle of flowering plants, including pollination, seed dispersal and germination using the Internet. Students will also study and discuss the key points and...

Students investigate the habitats of living things and the cycle of the food chain. In this scientific inquiry online lesson, students examine the habitats of plants and animals as well as the food chain as they sort pictures of living...
