Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts...

Protect skin from UV radiation! Groups design and conduct an experiment to test the effectiveness of UV safety products. The groups collect the data from the experiment and prepare a lab report. In the second day of the activity,...

Build and design to rock and roll. Pairs research building design in earthquake areas and use computer simulations to see the effects of earthquakes on buildings,. They then sketch and explain a building design that would withstand...

Bring the science of space exploration to the classroom. Young learners explore the mechanics of the parachute-landing mechanisms on the Mars Rover. They design and build their own parachute models and test their ability to land a probe...

Don't waste all that carbon dioxide. Scholars first produce carbon dioxide by mixing baking soda and vinegar. They measure the masses of the reactants and products to verify the law of conservation of mass. As a culminating activity,...

Do not let the class just sit and rot. Pupils learn how decomposition and nutrient recycling is important to an ecosystem. Groups design an experiment to determine how environmental conditions affect decomposition. They develop a poster...

Just this once, it's okay to throw things in class. Out of craft sticks and rubber bands, pupils build catapults to launch an object of choice. This can be a ping-pong ball, a marshmallow, or any other small item. As long as it hits the...

Go fly a kite, then fly a plane! The 19th part of a 22-part unit on aviation looks at the way kites and gliders help aid in the understanding of flight. Pupils discuss how engineers used kites to influence airplane designs.

What's that silly thing spinning in the wind? It's a whirligig! Explore wonderful windy whirligigs with a STEM-based unit that teaches the science and concepts behind these gigs. Scholars discover how gravity and air resistance...

Build problem-solving skills with science! Step-by-step videos walk investigators through each stage of completing a science fair project. Scientists learn to formulate a testable question, design an experiment, collect data, draw...

Students examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.

Design protection from high-speed particles. The STEM lesson plan highlights why astronauts need protection from space debris. Pupils use the design process to design, build, and test a spacesuit that will protect a balloon from a...

Use simple machines to escape from a tree house. Pupils learn about simple machines and how they are useful in everyday life in a STEM lesson. Groups then design a device to rescue a friend stuck in a tree house.

You have to crack a few eggs to make a good engineer! Working in small groups, young scholars design, build, and test devices that protect an egg from breaking when dropped from a ladder.

Students use experimental procedures to design and test the flight distances of paper airplanes. For this flight experiment lesson, students use the experimental science process to design and conduct an investigation to determine if the...

Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...

The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of...

Let me get an angle on this! Investigate the orientation of a photovoltaic panel and its effect on efficiency. By using a light source, learners collect and plot current output to determine the ultimate orientation. The resource includes...

What is science? Sitting in a whole group discussion, scholars first share their ideas on science and how to conduct investigations. They learn about the steps for scientific inquiry and experimentation. Once finished, individuals then...

In this physics worksheet, learners design and build a multi-range voltmeter. They answer 3 short answer problems about the device.

Help your class determine the types of pollutants coming from vehicle exhaust. Groups use an air quality monitor to determine the emissions from different vehicles, to gain knowledge about combustion energy, and to predict how the...

This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...
