Different types of energy are the focus of this science resource. Learners identify situations in which kinetic and potential energy are exchanged. They conduct an in-class inquiry which leads them to discover that there is a limit to...

Comprehend that many human characteristics-all physical traits and possibly many personality traits-are determined by our genetic makeup. These activities demonstate that all physical traits are genetically determined, some evidence...

Krill is a very small ocean animal that is key to keeping the ocean ecosystem going. The class reviews food webs and chains, learns about the importance of krill, discusses krill anatomy, builds a model of a krill, and then has a...

Why are the properties of the water important when exploring the ocean? Young scientists discover the tools and technology used in deep sea exploration in the fourth installment in a five-part series. Groups work together to...

Sure to be a hit with your charges, here is a science lesson that has lots of hands-on activities packed into it. The focus is simple machines, and how they help us perform work. After a discussion and demonstration session, groups of...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Pupils pose their hypothesis, they ready their instruments, then record their observations. This is the science of sound lesson plan. They move through 5 stations, each focused on a different element of aspect of sound. Check this lesson...

This is an information-intense presentation for any science class you might be teaching that will study ionising radiation. The material is specific to cancer diagnosis and treatment, and one of the forty-two slides also touches on using...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Students investigate how fruits and vegetables change and grow.  In this life cycle of fruits and vegetables lesson, students observe the changes in fruits and vegetables as they grow and record the colors on a worksheet.

Neptune takes 164.8 Earth years to travel around the sun. In the fifth of 22 lessons, young scientists create a travel guide to a planet in our solar system. They provide tips for others on what to bring, what they see, and their...

During the Battle of Baltimore in the War of 1812, only 25% of the bombs and rockets fired at Fort McHenry actually reached their target. Using an interactive online simulation, combine your historical study with physics and...

Bubbles aren't just for children. In the third installment of a seven-part series, teenagers use bubble solution to create bubbles and observe patterns of refraction on the bubble surfaces. Application of this concept to thin films in...

Learners will love a weeks worth of bone study. They use bones and characteristics of bones to explore the evolution of hominoids. Bones are compared, categorized, and considered. A great way to bring physical anthropology and material...

Why are car manufactures required to install seat belts and airbags; do they really make that big of a difference? Scholars use a simulator to determine the amount of force dissipated by a seat belt and airbag in a head-on crash. This is...

Students participate in a lesson that investigates Newton's Second Law of Motion. They conduct an experiment of observing balls that are rolled down a ramp. The lesson includes background information for the teacher for preparation and...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Middle or high schoolers transform into oceanographers in a week-long simulation. To begin, each group follows directions to create a model of the ocean floor with specified features. Next, the groups prepare to set sail on a research...

Discover firsthand the effects of internal waves on coral reefs. Through a series of experiments, learners simulate internal waves and upwelling events as they make observations on the movement of water and other debris. They then...

Young scientists from any region can take a scientific journey and be exposed to weather changes that include rain and snow.

Third graders practice making predictions about weather from conditions they observe on weather instruments and weather reports. Learners are introduced to the most basic weather reporting instruments: the thermometer, the wind vane, the...

Youngsters are introduced to the basic principles and uses of the wheel and the axle. They come up with every day examples of simple machines and look into why the wheel and the axle are best-used as a paired machine instead of used...

The principles behind pulleys, levers, and simple machines are the focus of a science lesson. In it, learners take part in a whole-class activity. There are two groups of pupils who each must lift objects with fixed pulleys and multiple...
