Gravity

What a great idea for scientific inquiry. This lab was intended for use as children explored a college campus, but it could be used anywhere. They go to three different places on campus and conduct a simple experiment that shows an...

We can't dig a hole through the Earth, so how do we know about the layers beneath our feet? Scholars learn about layering through hands-on exploration of common materials. They study the characteristics of each layer and apply their...

Here is a fabulous set of teacher's notes that will make your next hands-on gravity and force lab fun and interesting. These notes provide you with three activities that allow children to make and test hypothesis regarding force,...

Earth is a complex structure. Learners explore their home, the earth, using a fun hands-on activity. They create tactile models of the earth using ordinary household materials that represent some common features: land, polar caps,...

Falling objects can be brutal if you don't protect your noodle! Scholars explore the motion of falling objects through measuring short intervals to determine if the distance traveled varies with time. Building off of this, scholars...

Is it really love that makes the world go 'round? Find out in an amusing interview-based video. The narrator asks visitors at a city park why Earth continues to turn on its axis. After several misguided attempts at invoking different...

Why does the moon stay put, never getting too close or too far from Earth? See the truth unfold through interviews and a simulation using a basketball and a tennis ball. The host helps guide the discussion, all while spinning a ball to...

Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

Learners read a short description about gravity and what it does and then explore the two ideas about how gravity works. After gaining a better understanding of the concept, individuals participate in a thorough experiment on what would...

Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...
