Seventh graders, after defining/brainstorm the task, divide up into groups and are assigned to an alternative energy source (wind, solar, or water) to research. They complete a presentation with visuals on their findings from their...

Students interactively explore the term transpiration. In this science/ecology lesson, students discuss what they would do if they were thirsty while conducting research in Brazil. Additionally, students write descriptive words to...

Students identify how waves transfer energy without transferring matter. They contrast transverse and compressional waves and relate wave speed, wavelength, amplitude and frequency. Lesson includes PowerPoint presentation.

Which food molecules must be present for cellular respiration to occur? Scholars view an informative presentation to better understand the process of cellular respiration. It details each step, focusing on the locations and the four main...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function...

If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

Young people between the ages of 11–13 need on average about 2,000 calories per day. Within the lab, groups learn about calorimetry and respiration. They explore how it pertains to humans and animals living the Arctic where cold...

Building on prior knowledge of the pervious lesson in the series, pupils explain the previous lesson to each other. Then they write a simple guide for a young child to read on the same topic. 

With global temperatures on the rise faster than ever recorded, the effects of a heating planet could be devastating. Allow learners to discover just what the world is in store for if the warming continues through a series of videos, a...

Scholars become part of the cycle of matter with a reader's theater that showcases producers, consumers, decomposers, and the sun. A diagram and discussion concludes the learning experience and enhances comprehension. 

Young scientists get to the heart of the matter as they complete this worksheet on the properties of solids, liquids, and gases.

What causes earthquakes? Second graders learn about stresses from plate movement with a set of hands-on activities. After tracing fault lines on a map with yarn, class members create a paper plate model of Earth to show its layers...

Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

The stability of the atmosphere changes on a daily basis. A kinesthetic lesson models how the stability of the air changes as it's warmed by the sun. Learners connect their models to the changing air currents and movement of warm and...

Create a simulation of acid rain in your classroom with lemon juice and bean plants to help kids study the effects of pollution on plants. In addition, learners will listen to a story and write responses based on guiding questions.

It is recommended that you conduct this fabulous experiment as a whole-class demonstration. Collect air samples from the environment, human exhalation, and car exhaust, then compare them for carbon dioxide content using bromthymol blue...

Is assembling the periodic table as simple as Tetris? Scholars arrange colored cards into a logical order and then make connections to the arrangement of the periodic table. Hands-on activities include adding trend arrows and analyzing...

Mammals are some of the newest organisms to appear on Earth. Young scholars complete an activity that results in a timeline showing the appearance of different types of living organisms. Provided with a list that spans from prokaryotes...

Explore the powers of ten while examining a Blue Morpho butterfly wing. Learners discover there is a lot more than meets the eye when one looks close enough.

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

Discover Impressionist painting as students investigate the 19th century combinations of colors characteristically used. Students experiment with their own paintings, utilizing primary and secondary colors.

Tree rings from North America give a continuous history of El Nino intensity over the last 1,100 years. Scholars learn how scientists use tree rings to create timelines demonstrating variations in weather patterns. The cumulative...
