Breaking Point
Leaf toughness can add to its herbivore appeal. Learns design an experiment to quantify leaf toughness and then perform their procedures. They follow the experiment with a set of questions that ask them to think about how leaf toughness...

Blowin’ in the Wind
Wind energy is making a comeback recently, and classes will want to take part! A hands-on lesson asks groups to build their own windmill that will lift a cup with varying weight. They use their windmill designs to experiment with angles,...

Bird is the Word
Tracking area birds can tell a lot about an ecosystem. Learners use that understanding as motivation to observe and record bird populations in their area. They use journaling to store their information and ultimately choose one bird as...
PBS
All Tangled Up
It is a tangled web the ecosystem weaves. Learners begin an activity on ecosystem interactions by building a food chain and then a food web with yarn as a group. To finish, they research local environmental changes that may impact the...

Super Sleuths
There's no such thing as the perfect crime! Your class of sleuths are ready to investigate the trace evidence at a crime scene and compare it to a list of suspects. They use their investigative skills to record physical properties of the...
PBS
Print Hints
It would be a crime not to give the lesson a chance! An inquiry-based lesson has pupils assume the role of crime scene investigators as they make observations about shoe prints. They look for patterns in the prints such as distance and...
PBS
No Slip Grip
The force will be with you during an inquiry-based lesson focused on friction. Young scientists explore the effect of different surfaces on friction. They use rubber bands to measure the amount of force needed to move an object on the...
PBS
Insulation Station
It's all about the material. Learners experiment with different substances as they try to keep an ice cube from melting. They draw conclusions by answering a set of questions about the types and amount of material that had the best result.
PBS
Twirling in the Breeze
Blow classes away with a hands-on lesson investigating wind speed. Learners use common materials to design and construct anemometers. They then test their anemometers and collect data on the wind speed created by a fan.
PBS
The Air in There
Feeling is believing! Youth discuss how they know air exists using evidence-based logic. They then create air cannons from cardboard, cling wrap, and rubber bands to demonstrate air is real—and powerful.
PBS
Star Power
Let there be light—or maybe not. Pupils learn about light pollution with an investigation of constellations. They create constellation boxes and experiment with different levels of light. Observations are then made about the lighting in...
PBS
Season Seeking
It's a time of change. A hands-on activity engages young scientists in a lesson highlighting the change of seasons. They brainstorm indicators of season changes in nature and then look for them. Next, they record observations in a field...
PBS
Cloud Clues
It's cloudy with a good chance of learning! An inquiry-based lesson begins with an exploration of transparent, translucent, and opaque materials. Young scientists then connect their learning to the different cloud types as they take the...

Feminist Philosophers of the 20th Century
Reclaim forgotten philosophers of the twentieth century. Feminist philosophers have shaped our current concepts of politics and gender, but they are seldom mentioned in the classroom. Change that omission with a lesson plan that includes...

Different Substances React Differently
Looks don't tell the whole story. Young experimenters explore reactions with substances that look similar. They observe the reactions that take place when combined with baking soda and use indicators to conclude they react differently...

Density and Sinking and Floating
Keep your class afloat with a hands-on density lesson. The challenging lesson has learners experiment with different materials to compare their densities. They learn that increasing or decreasing the amount of the material doesn't change...

Using Dissolving to Identify Substances
It's time to test observation and dissolving skills! After investigating the process of dissolving in previous lessons, pupils see if they can use their dissolving skills to identify substances. They dissolve known and unknown substances...

Designing a Solar Phone Charger
What a bright idea! Working in groups, scholars design a solar phone charger by applying concepts from the unit. They use solar modules and buck and boost converters in their creations, which must be able to charge a phone after...

Exploring Buck and Boost Converters
Boost one's knowledge of converters. The fourth of seven installments in the Off the Grid unit looks at buck and boost converters, which lower and raise the input voltage. Scholars apply the converters to adjust the output voltage to...

Designing a Solar Charger
The sun can even charge batteries. The fourth of five lessons in the Solar Transportation unit has pupils design a charger that uses solar modules to charge a 12-volt lead-acid battery. They estimate the charge that accumulates and...

Geared Up
Get the class's gears turning! Pupils first watch a video that introduces the situation: Given three gears, how many turns will it take for the dots shown on the gears to line up? They count the number of spurs on each gear, then use the...

The Clapper
Give a round of applause for completing the task. Scholars watch a video that shows an extremely fast clapper and a timer. The activity requires applying concepts of rates and proportional reasoning to estimate the number of claps in one...

Rope Jumper
Jump at the chance to use the idea of rates. Young mathematicians watch part of a clip of a Japanese TV show where a contestant jumps rope as fast as possible. They use the data for the number of jumps and the number of seconds shown in...

Deep Freeze
Warm up to the idea of subtracting integers. After watching a video where the contents of a cup instantly freeze when tossed into the air, pupils estimate the air temperature of Duluth, Minnesota (where the video was made). They then use...
