Students explore natural resources of our planet. In this natural resources lesson, students use an apple to explore the land, water, and climate. Students also use the apples to explore the part of our planet that can grow food and...

The actual lesson itself is not unique; groups discuss and rank different sources of energy in order of their cumulative greenhouse gas emissions. They compare their prediction to real data. What makes this resource valuable, is that it...

What a great way to explore the scientific process! Learners conduct an experiment in which they use sugar and water to illustrate the concept of solutes and solvents. With this hands on approach, they are bound to remember what they...

Groups of young oceanographers get to use action figures to experiment with the property of buoyancy! This memorable lesson plan provides detailed background information, a link to the laboratory worksheet, and thorough instruction...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

Discover the coldest animals in the world with a lesson about the Arctic habitat. Kids use a glossary and information sheet about animals found in the Arctic Circle to complete several activities, including tracking the lemming...

Learn about the mammals of the sea with a lesson about seals, sea lions, and walruses. Kids study the characteristics of each pinniped with flash cards and information, and then analyze data about elephant seals, measure heat loss...

Whether you are starting a class garden, reading a story about gardens, or want to teach your little ones about sustainable living, these vocabulary cards are a great introduction. Featuring words like watering...

Everyone has a mouth watering, delectable delicacy that they can talk or write about. Pupils will use this writing prompt worksheet to not only detail their favorite food in writing, but also illustrate what they are...

How do oceanographers make maps under water? Junior explorers discover the technologies and processes involved in creating bathymetric maps in part three of a five-part series designed for fifth- and sixth-grade pupils. The lesson...

Get into springtime with a festive practice sheet designed to test scholars' knowledge of grids. Learners locate items such as watering cans, snails, and flowers following the x and y-axis. Worksheet themes include Earth Day, gardening,...

A dripping faucet may be enough to drive you crazy, but it also teaches you a little about ratios. Presented with the volume of a sink and the rate the water is dripping, scholars must devise a plant to determine how long it will take...

Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

Heat up a lesson on solar energy. The first of three parts in the Experimenting with Solar Heaters unit has scholars construct solar heaters. They then use them to heat up a container of water and calculate the amount of heat energy...

If changing one variable can improve a design, why not try changing more? Using the results from the previous activity, scholars decide on the variables that caused the most improvement in the effectiveness of the solar heater. They take...

Students examine the concepts of micelles, polarity, solubility, and properties of detergent in an experiment with milk, water, and food coloring. Students complete a Take-Home Challenge in which they experiment with the behavior of food...

Groups of two to four work together to design, construct, and experiment with a boat. Each boat must include all of the major parts of a real ship, be less than 12 inches long, and be able to carry a load up twice its own weight in calm...

Students experiment with swirling sand and stone inside a bottle for this assignment. They predict what the final design will turn out to look like. Students after observing the bottle still, turn the bottle upside-down and experience...

Discover the calorie content of foods by observing how much heat they produce in water. If you have a calculator-based laboratory (CBL™) insturment for collecting data, then this laboratory worksheet will not need any changes. If...

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Learners use a pipette to mix small amounts of food coloring into water. They visualize the small quantities of parts per million and parts per billion. Contrary to the title, the lesson is about liquid amounts rather than gas amounts....

You know that liquid nitrogen turns into a gas at room temperature. Place some in a two-liter bottle for a physics demonstration of the ideal gas law. Beware, however; this is a dangerous demonstration! Not to mention that you may not...

Students explain that there are pollutants in the Anacostia River, what those pollutants can cause, and how to prevent further pollution. They read about pollution and graph levels of fecal coliform in the water.

Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...
