Urban Ecosystems 5: In Defense Of Cities
Students explain that while cities have unattractive features, the density of human life enables energy efficiency, mass transit, recycling, and other benefits which are difficult or impossible in rural areas. This is the fifth in an...

Motion in Two Dimensions
Two activities employ the use of kinematic equations for determining projectile ranges. They both require the use of a toy dart gun. Included in this resource are both the teacher's guide and student laboratory sheets. This is an...

Investigation: Acceleration
Take a look at acceleration within the context of automotive technology. They vary the mass on a toy car and run it down a ramp, exploring Newton's second law of motion. Though this is a classic lab activity, you will appreciate the...

Making Cookies- How many per hour?
Fifth graders measure how long it takes to make cookies. In this measuring time instructional activity, 5th graders explore how to manage time. Students decide when to start making breakfast on time, how to calculate playing time into...

Measuring Earthquakes
After a brief discussion on earthquakes, make a makeshift seismograph to record the shaking of the table that it sits upon. While the background information will be useful to you as a teacher, the seismograph does not seem like it would...

States of Matter
Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

Christa's Lost Lesson: Effervescence
How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Popcorn Neutrino Lab
Students parcticipate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, students measure the mass of popcorn. They also record predictions of the mass of the kernels after they...

Einstein's BIg Idea
High schoolers discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.

Weighing a Dinosaur
Young scholars role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.
Curated OER
Crash! Bang!
Students study the physical force of linear momentum by investigating collisions. They analyze the difference between elastic and inelastic collisions. They calculate linear momentum.

The Lost Newton's Laws Lesson
Young scholars explore momentum. For this physics lesson, students perform an experiment in which two balls are released on slanted boards while young scholars observe which ball will go the farthest and the fastest. Students define and...

Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Conservation of Momentum
Assist your class with understanding collisions as they apply the Law of Conservation of Momentum. Pupils measure the momentum before and after manipulation of two objects so that one strikes another in an inelastic collision. The lesson...

Thirsty Rocks: Please "Porous" a Drink!
A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...
