Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Discover a world too small to see. In the lesson, young scientists learn about nanotechnology and brainstorm ideas for new applications of it. They perform an activity to determine how surface area changes when objects are made smaller...

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

Tomorrow's engineers visit an intriguing website about inventions that have changed the way we live. Biographies of child inventors on the suggested website aren't easy to find, so make sure to find some stories to share in place of...

Students consider the development of different societies. In this environmental building activity, students consider local resources and how societies choose to use them. Students use their findings to design a 'green' building for use...

Climb up the staircase of engineering knowledge. After watching a video of a carpenter measuring out steps for a set of stairs, pupils learn about the terminology and regulations involving stairs. They see how to use a rule of thumb when...

Candy rocks! A sweet lesson offers a different take on the rock candy experiment. Groups use a supersaturated sugar solution to create rock candy. Pupils then add other ingredients to the solution to test their effect on the...

Emerging nutritionists explore what it means to be healthy. In the beginning of the unit, your class will examine the five food groups and learn how food gets from the farm to our plates. This leads into the investigation of...

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...

You can make it if you bake it! Young scientists model electronic chip fabrication with an easy bake oven. They create a design to embed in their brownie "chips" and compare their models to wafer production in basic nanotechnology.

In 2006, about 20 percent of the world's electricity was generated from hydroelectric power. In the presentation, scholars review the water cycle and gravitational energy to begin to understand how humans harness the power of water. They...

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...

How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

How do scientists know they're right? Truth be told, they don't always know. Explore the scientific process using mystery tubes in an insightful activity. Young scientists discover how to approach and solve problems in science, how ideas...

Students recognize epoxy glue formation as two part polymerization (usually the curing agents act as co-monomers). They monitor the reaction by the changes in viscosity of the reacting mass, the temperature rise and fall, and the...

Learners know that participation in sports requires energy. They comprehend that we get energy form the foods that we eat and the air thta we breathe. Converting food and air into usable energy is defined as celluar respiration. Students...

Students create a model of a comet. For this space science lesson, students compare their model to the characteristics of a real comet. They evaluate and make necessary modifications to their original design.

Challenge small groups to build a structure that catches a raw egg without breaking—working collaboratively and applying mathematical and engineering principles. Pretending the frame was made by a business, scholars create a marketing...

Learners explore the challenges astronauts face while eating in outer space. In small groups, they design and construct an original model device to assist astronauts eat in a microgravity environment.

Students design and build a device to protect and accurately deliver a dropped egg. They review and study a number of vocabulary words that are associated with this lesson. They work in a small group in order to develop a successful...

Students analyze critical load and how to reinforce the design of a structure to hold more weight. They examine basic structures and which materials to select. They create a prototype to hold more and more weight.

Students work on problems in which they investigate conduction, convection, and radiation. They attempt to maintain the warmth in one can of soda while cooling the other as much as possible in a thirty minute period. They examine how...

Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

Students design and create robotic cars using Legos and the Robolab program. They hold a "snail race" where the slowest car that can be determined to be actually moving is the winner.
