Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

It's time to roll up those sleeves and get a little dirty in the second lesson of this series on the science of food. Investigate where plants and animals get the minerals they need to live in this two-part exploration of soil. First,...

Kindergartners learn about the ways force can stop and reverse motion. Several illustrations of children help them determine if the motion is causing an item to change direction. Next, they conduct an experiment to see if a water balloon...

Students make accurate drawings of a classmate's shadow. They note position of the sun in the sky. They identify a connection between the direction of the shadow and the location of the sun. They observe changes in shadows over time.

In this scientific investigation worksheet, students rotate to seven different stations and follow directions for each given investigation. They make observations and answer questions in order to solve the given problems.

Super scientists tests the toxicity of water using radish seed bioassays. Over the course of five days, scholars observe the germination process of several radish seeds, looking closely at their roots to determine the level of toxins...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Though it isn't a novel activity to prepare onion cell and Elodea plant cell slides as examples of cells in a microbiology unit, this resource will leave you thoroughly prepared. As pupils examine the slides that they prepare, they draw...

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Is it possible to change the color of clouds? A three-part activity explores the scattering of light by the water droplets that make up clouds. After observing a demonstration, curious scholars conduct their own investigations of the...

Geology beginners examine three different rock samples and determine their origin by their characteristics. By making and recording observations, they become familiar with features of igneous, metamorphic, and sedimentary rock types....

One of the key objectives of Europe's Copernicus Earth program is to monitor the temperatures of the oceans and seas on Earth. Young scholars learn the effects of different heat capacities through two experiments. These experiments...

What's better than a pendulum for studying motion and periods? A double pendulum! Young physical scientists use an interactive to explore pendulum motion—times two. The resource boasts a host of parameters to change and a running graph...

Young scientists use food coloring and celery stalks to determine how water travels through plants. 

Young entomologists construct three types of insect traps—pitfall, pollinator, and panel—before setting their traps out and observing what they caught. They then observe what types of insects the different traps attract.

Get things cooking with the first lesson in this series on the science of food. Working in small groups, young scientists make and record observations about different mystery foods. These descriptions are then shared with the class and...

Young scientists use a globe and a light to simulate the rotation of the earth and sun to show the seasons. Additionally, they simulate direct sunlight and indirect sunlight showing intensity of the sun, and answer questions based...

Young scholars investigate soap, how it is made and its structure. In this soap lesson, students observe a demonstration of soap being made. Young scholars observe the properties of soap and how soap performs in "real-life" situations...

Students examine and define what technology is as well as the differences between science and technology. They assess the role of science and technology in society, conveniences technology offers and create a chart to compare the...

Crystals form before your very eyes! What sixth grader wouldn't enjoy this lesson on igneous rock formation? Using hot Salol, junior geologists observe the crystal formation process as the material cools. This comprehensive lesson plan...

Most drugs used today come from nature, so the discovery of new ecosystems in the deep sea is exciting from a medical perspective. Scholars develop their own bioassay to test germination rates in seeds. 

Students investigate magnetism. In this physics activity, students create a KWL chart about magnetism and research various suggested websites to find out more about magnetism. Students log on to the "BrainPOP" website and view a short...

The universe is full of a mystic matter people cannot see. Pupils respond to 10 questions about the stuff in the universe. Most of the questions involve the big bang theory and dark matter. Learners find out how astronomers have found...

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third instructional activity of the series, learners conduct an experiment, demonstrating...
