Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Rainy day schedule doesn't mean you can't stay fit! Use a collection of indoor physical activities during periods of inclement weather, substitute teaching days, or for those afternoons when your class just wants to move around!

Serve up a slice of math for Pi Day! A combination of fun, hands-on lessons and helpful worksheets encourage learners to practice finding the radius, diameter, and circumference of different circles.

Yuck, does my deodorant kill that? To test whether deodorant is anti-bacterial, class members use petri dishes to grow control bacteria and bacteria from sweat, and then compare them to see if deodorant effects the...

Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...

What is the difference between weather and climate? This is the focus question of a lesson that takes a deeper look at how weather data helps determine climate in a region. Using weather and climate cards, students decide...

What do your vital signs tell your doctor? An engaging hands-on lesson has your learners monitor their own lung capacity, blood pressure, and heart rate. They then connect the vital measures to the workings of the circulatory and...

Introduce your class to air masses and how they affect the weather with a lesson that focuses on the differences between high and low air pressure systems. The class explores actual weather data using archived weather data.

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

What does an MRI machine have to do with a slinky? This activity challenges learners to run a current through a slinky and use a magnetic field sensor to measure the magnetic field. Groups then change the length of the slinky to see...

Create an egg-citing study of energy. Pupils investigate the effect of height and mass on the overall amount of energy of a falling object. The fourth segment in a six-part series on energy uses a weighted egg falling from different...

Looking for a different approach to triangle congruence criteria? Employ transformations to determine congruent triangles. Learners list the transformations required to map one triangle to the next. They learn to identify congruence...

To an engineer, the glass is never half full; it's just double the necessary size. The fifth installment of a nine-part technology and engineering series teaches pupils about the idea of ergonomic design. Measurements of popliteal height...

The good thing about building this rover is you get to eat it afterwards. Pairs determine rover parts they want to include in their design based upon their cost and usefulness. The teams design their rovers, build them from edible...

Learners explore logic and use Geometer’s Sketchpad and patterns of logic to solve a puzzle.

For this mind-bending activity, young engineers explore this question of whether or not light actually bends. Using holographic diffraction gratings, groups design and build a spectrograph. The groups then move on research a problem...

What do you need to prove triangles are similar? Learners answer this question through a construction exploration. Once they establish the criteria, they use the congruence and proportionality properties of similar objects to find...

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

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. 

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

Look at climate change around the world using graphical representations and a hands-on learning simulation specified to particular cities around the world. Using an interactive website, young scientists follow the provided...

There are five methods of seed dispersal. They include gravity, mechanical, animal, water, and air. Scholars study seed dispersal in lesson five of the series of six. Through discussions, hands-on analysis of different seed types, and...

Try your hand at scale models. Scholars create a scale model of an object using a scale factor of their choice. As part of the project, they give presentations on their processes and calculations. This is the last installment of the...
