Rocket-Powered Ski Lift
If a ski lift had rockets, imagine how fast it would be! Scholars let their imaginations take flight as they build models for such a ski lift. Rather than using a rocket, though, they'll use a much safer balloon as the power source.

Thinking Like a Scientist
Students explore the scientific method. Students identify the steps in the scientific method and explain what each step means. Students use these steps to determine if boys or girls are taller in their classroom.
Curated OER
Chemical Changes to Matter
Students analyze the causes of corrosion. In this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Students discover the causes of rust and tooth decay.
Curated OER
Balloon Jets
Young scholars investigate how fuel amount affects the distance traveled by balloons. In this physics lesson, students collect data and create a pictograph. They interpret data and formulate a conclusion.
Curated OER
Making A Natural pH Indicator
Students make their own pH indicator from red cabbage. Red cabbage contains a chemical that turns from its natural deep purple color to red in acids and blue in bases. Students boil the cabbage to get the pH indicator.

Observing Buffers In Lakes, Ponds And Streams
Young scholars observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.
Curated OER
Determining The pH Of Common Substances
Students use a pH indicator to measure the pH of some fruits, common beverages, and borax. Students discover how to differentiate between an object that is an acid or a base.
Curated OER
Picket Fence Free Fall
Young scholars measure acceleration using a Picket Fence and a Photogate. In this physics lesson, students drop an object and measure the acceleration of the object free falling. They log their data using the TI.
Curated OER
The Water Cycle
Young scholars access prior knowledge of the water cycle by completing a KWL. In this water cycle activity, students follow the movement of water through the water cycle.
Curated OER
School Temperatures
Young scholars collect and record temperatures throughout the school. Using this information they compare and contrast the temperatures recorded from various spots throughout the school.

Dripping Wet or Dry as a Bone?
Students use a sponge and water model to explore the concept of relative humidity and create a percent scale. They define humidity and saturation, build a simple humidity/saturation model, collect, predict and interpret data, and create...
Curated OER
Trajectory and Range of a Projectile
Students investigate the factors affecting projectile trajectory. In this physics lesson, students calculate the range, time and speed of projectiles using mathematical equations.
Curated OER
Bubbles
Students observe the characteristics of bubbles. In this scientific inquiry lesson, students use a bubble solution and a wand to make bubbles and observe their characteristics. Students identify the shape and the color of the bubbles.
Curated OER
Designing Windmills
Students study mechanical engineering and how it plays a part in the creation of windmills. They design and test their own windmills using various materials and sail designs.
Curated OER
Wonders of Weather
Students investigate weather disasters by creating a virtual tornado. In this wild weather lesson, students define a vortex and describe how a vortex keeps a tornado moving and causing damage. Students utilize salt, detergent, water,...

Early Central Heating
In this history of heating worksheet, students read about the different ways of heating rooms over time. They answer three critical thinking questions about conduction, convection and heating.
