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...

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...

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...

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

There are patterns in nearly everything — even earthquakes. Pairs research current earthquakes to see if there are any patterns. They determine the mean, median, and mode of the earthquake data, along with the maximum and...

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

High schoolers investigate a problem and background information including the typical capabilities /limitations of a paraplegic. They develop an understanding of the attributes of engineering design.

Seventh graders identify and create questions and hypotheses, dependent and independent variables and form a conclusion that can be answered and tested through scientific experimental investigation. In this relationship lesson, 7th...

Pairs use an online simulation to determine the epicenter and magnitude of an earthquake. Using real data about the earthquake's maximum S wave amplitudes, they then determine the magnitude. The resource provides a great career...

Sometimes it seems as if earthquakes hit the same places over and over again. Class members study Japan in order to determine why earthquakes keep happening there. Pairs work together to research and try to determine whether there...

Students listen to a read aloud of Shel Silverstein's, The Little Blue Engine. They design and build a Lego train that climbs a three foot incline, one foot at a time. They draw and write about their design.

Young scholars build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.

Students work together to complete a project on probability. In groups, they solve probability equations based on the formula and scenerio given to them in a PowerPoint presentation. To end the lesson, they take a quiz on each problem...

Learners build a stable car after examining the RCX. They determine how to incorporate the RCX into their design using Legos to build a car.

Students design a car with two motors and then program the car to accomplish specific tasks within Pilot 4. They work in teams in order to program their own car in order to accomplish specific tasks outlined by the teacher. They write...

Students are introduced to the function and design of the following Lego pieces: beams, bricks, plates, axles, tires, hubs and bushings. They then work with a partner to build something using only these pieces.

Students examine the heart and vascular system and the need for artificial valves. After explaining how heart valves function, they design their own heart valves for experimentation. They predict the speed of fluid flowing through...

Find out if your class agrees with Ice Age: Continental Drift ... or if it's just a fun family movie! Class members research the theory of continental drift, examine evidence of plate tectonics, connect...

Prepare to accelerate your Android. Pupils prep for the upcoming activity in this third installment of a four-part series. The lesson progresses nicely by first introducing different types of acceleration to the class. The teacher...

Small groups use rubber bands to accelerate an Android device along a track of books. They collect the acceleration data and analyze it in order to determine the device's velocity. 

Students analyze graphs to determine relationships between variables and rates of change. They determine the basic concepts about static reaction forces. They determine the slope and equation of a line.

Pupils work together to build a music box. They create figures that move when a song plays. They answer discussion questions to complete the lesson.

Students build Lego cars with attached light sensors. They program the car to enter a tunnel and reverse out when it records a darker light reading.
