Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

Kindergarteners practice new words through listening to and reading the science book Butterfly by Jenny Feely. The teacher will first choose words that are essential for understanding the text. Then, using pictures in the text,...

Students examine and categorize plants in their own schoolyard desert garden and then observe other plant areas of their schoolyard.

Youngsters listen to the story, "There Was an Old Lady Who Swallowed a Fly." After discussing the story, going over new vocabulary, and repeating the rhymes in the story, they study the parts of a fly. They finish by creating a fly on...

Young environmentalists study the effects that pesticides have on birds, such as the peregrine falcon. They also look at predator/prey interactions. Some wonderful in-class activities accompany an inventive lesson. After an activity that...

Fifth graders take a close look at how energy changes from one form to another within their surroundings. They also study the ten different sources of energy and determine which are renewable and which are non-renewable. This seven-page...

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 study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

Learners use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Learners then discuss the different body plans of the organisms and the...

Students study the water cycle and create a booklet entitled: "Discover the Wonder of Water" They observe and record data regarding evaporation, condensation, and precipitation and how water moves from a solid to a liquid to a gas. They...

Predict whale populations using different beans as whales! Learners observe different types of beans in a dish knowing that each bean represents a different kind of whale. They then predict how many "whales" there are in a certain area....

Kids observe, classify, and measure tree leaves with a scientific eye. They examine leaves, group them according their attributes, and use standard units of measurement as they compare their sizes. They access a web site to learn how...

Demonstrate the path of the sun across the sky at different times of the year with an engaging science lesson.  Learners use a series of questions and diagrams to examine the movement of the sun and appearance of the sky around...

Future weather forecasters collect daily temperatures over a period of time. Afterward, they compare their data with monthly averages, as researched on national weather websites, in order to grasp the difference between weather and...
