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
Pupils 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.

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
Students measure acceleration using a Picket Fence and a Photogate. For 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
Students access prior knowledge of the water cycle by completing a KWL. For this water cycle lesson, 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.

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
Ziplock Chemistry
Students investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

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.
Curated OER
Boyle's Law
In this Boyle's Law worksheet, students investigate the relationship between the pressure and the volume of a gas at constant temperature. They use a syringe and a pressure gauge attached to a computer to collect their data. They create...
Curated OER
Sound/Pitch
Students explore how pitch changes when using instruments that are plucked, blown, and hit. In this sound and pitch lesson, students blow across the top of bottles that are filled with water to create sound. Students use recorders...
Curated OER
Atmospheric Processes - Conduction
Students explain the process of conduction using a molecular explanation, and explain how different materials conduct at different rates.
Curated OER
Understanding the Four Forces of Flight
In this four forces of flight worksheet, students read a 1 page article on flights, answer 5 questions with multiple choice answers, draw a line to connect the four forces to their definitions and answer 1 short answer scenario.
