Students study the parts of the human respiratory system while examining the gas exchange that takes place in the lungs. They make a model lung. They look at how the respiratory system is affected by spaceflight.

Students investigate how kidneys function. They discuss how a dialysis machine works, and conduct an experiment in which they filter different substances through a plastic window screen, various sizes of hardware cloth, and poultry...

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. Students investigate...

Young scholars examine Newton's three laws of motion to discover what causes it and how it changes. They conduct motion experiments by building catapults and constructing balloon rockets. Finally, they conduct peer studies correlating...

Students discuss Newton's laws of motion. The conduct motion experiments by building "Newton Rocket Cars" from assorted materials. They propel the cars with rubber bands and wooden blocks and record the distance traveled on data sheets.

Students examine the basic concepts of radio waves and magnetic fields. They study how the AM radios are built and demonstrate the concepts of amplitude and frequency.

Students construct an interactive ozone depletion model using gumdrops and toothpicks. After analyzing the data obtained from the model, they record it on butcher paper and complete worksheets about oxygen.

Students build and observe a simple aneroid barometer to discover changes in barometric pressure and weather forecasting. They graph changes in barometric pressure for two weeks and make weather predictions.

Students investigate the effect of weight on normal friction or the friction due to surface roughness. They tell about the effects of contact area that occurs as a result of molecular attraction by looking at data on line graphs.

Students engage in a discussion about what a parachute is and how it works. They create a parachute using different materials that they think will work best. The students test their designs, which will be followed by a class discussion...

Students observe a demonstration of Newton's third law of motion using a small wooden car. They discuss Newton's third law of motion and what happens to motion if the mass or acceleration is increased, construct their car, and record...

Young scholars examine the motion of pendulums and come to understand that the longer the string of the pendulum, the fewer the number of swings in a given time interval. They see that changing the weight on the pendulum does not have an...

Students investigate different methods (aeration and filtering) for removing pollutants from water. They design and build their own water filters. Students identify the pollutants in a water sample using sight and smell, explore what...

Students examine fossil fuels, nuclear and renewable fuels. They study investigate types of heat transfer such as convection, conduction, and radiation. They complete crossword puzzles based on the vocabulary. They design, construct and...

Learners design and create packaging material for food. In this snack attack lesson, students design a package to protect a food item from heat and water. Learners consider costs of materials, design, and test the package to see if it is...

Students simulate the impact of fluctuating river volumes on structures and landforms. They experiment with table top-sized riverbed models and water. Students consider how human design can help mitigate the effects of a flood.

Students work with a partner, Styrofoam ball and light source to simulate the positions of the Earth, Moon and Sun at various stages during the phases of the Moon. They describe why the Moon is visible from Earth and complete a worksheet.

Students examine the concept of angular momentum and its correlation to mass, velocity, and radius. They listen to a teacher-led lecture, conduct an experiment with rotational inertia, angular momentum, and rotation speed by making...

Learners study the number of chromosomes in the body cells, sperm cells, and egg cells of humans. They define allele, and examine the difference between dominant and recessive alleles. They complete an activity with jelly beans that...

Students randomly select jelly beans that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from...

Young scholars set up and run the experiments they designed in the lesson, 'Population Growth in Yeasts,' using simple yeast-molasses cultures in test tubes. They demonstrate understanding that several environmental factors can...

Students participate in an activity that introduces them to the concept of binary coding as a language. They decode messages using special boards that has its own code for different letters. They create new codes by rearranging wires...

Students build and program a LEGO robotic car as well as measure and graph its speed. They acquire familiarity with principles of construction, motion, design and problem solving. They compare a robot's speed over two different surfaces...

Students work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. They analyze Ohm's Law, power, parallel and series circuits, and ways to measure voltage and current.
