Investigate which items float and which ones sink using this resource.  Learners participate in an activity in which they investigate this phenomena. Then they describe the experimental process, and learn how to display their results.

Students explore ocean biology by participating in a plant growing activity. In this seaweed activity, students identify the importance and uses of seaweed in the ocean and examine different seaweed samples. Students utilize an aquarium,...

Students create spectral colors. In this hands-on science lesson, students examine the electromagnetic spectrum as they follow steps to create a model that separates and displays light.

Fourth graders explore physical changes and the true life story of Wilson Bentley. They observe the changes that take place with snowflakes. Students discuss what happens when snow flakes melt. They create their own snowflakes using...

Students experiment with heat. In this physical science instructional activity, students engage in hands-on activities to develop concepts related to heat. Students offer explanations for their observations using given vocabulary.

Students create a definition of matter. In this physical science lesson, students work in pairs to sort items printed on cards into several categories (matter, non-matter, and unsure) and agree on a definition of matter.

Young scholars participate in a physical fitness activity about water. For this water conservation lesson, students discuss how to conserve water and the amount of water most people use in a day. To illustrate this amount young scholars...

Students investigate chemical energy. In this physical science lesson, students blow on saltine crackers to demonstrate how chemical energy in food can be converted to motion. Students compare the saltine cracker experiment to how...

Students explore climate change by participating in a physical science experiment. In this greenhouse effect lesson plan, students discuss the impact global warming has on our environment and how it works. Students utilize a glass jar,...

Students explore using energy from the sun for heating and cooking as they build and compare the performance of four solar cooker designs. This excellent two-day lesson has groups of students build and test a variety of solar cookers....

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...

Students learn the scientific principles of centripetal force through research and experimentation.

Students explore energy as it relates to body function. Data about the personal physical activity of students is gathered and entered into a database which is utilized to test hypotheses made.

Learners investigate the brain as the organ that regulates all of their physical, emotional, and cognitive responses. Some of the components of mental illness are examined inn this lesson.

Students examine the muscular system. In this muscular system lesson, students first draw a realistic representation of their leg or arm bones. Students do several activities to attach these bones to "joints" with string to simulate...

Students identify predator/prey relationships based on the food web of the tropical rain forest ecosystem and realize they need a food web for survival. In this food web lesson plan, students complete a role play activity being animals...

Students investigate and explore the three states of matter. They read and discuss the NASA article "The Engine That Does More," identify examples of each state of matter, and as a class complete a section of two worksheets. They...

Students identify Newton's Laws of Motion. They students explore Newton's Laws of Motion and apply the second law with a classroom activity. The videos will provide visual examples of the effects of gravity while riding on a roller coaster.

Students participate in a lesson designed to illustrate these concepts using simple materials. They use Science process skills to observe, measure, predict, make inferences, and communicate while completing the activity. Proper safety...

Students explore physics by participating in a science activity in class. In this flight properties lesson, students identify Bernoulli's principle of flight and his theory of statics and motion. Students conduct a demonstration by...

Students explore space science by conducting an experiment in class. For this Moon lesson, students define a list of space science vocabulary and read the book The Moon. Students utilize shoeboxes and string to conduct a sunlight...

Students explore and discuss what they do in their free time, what nutrition means and how to participate in physical activity to keep themselves healthy. They list as many ways as they can think of to increase their physical activity...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

Create a scaled model of our solar system in your classroom! Scholars work collaboratively to build paper mache planets and hang them in their proper position to showcase each planet's location in the solar system.
