Buoyancy in Water
Change where an object floats in water. Pupils experiment with a Cartesian diver by squeezing on the side of a plastic bottle. Learners pay attention to the bulb of the pipette as the bottle is squeezed to determine what is happening...
University of Waikato
Investigating Sea Level Rise
Find an explanation for the sea level rise. Pupils investigate the difference that melting land ice and sea ice have on the sea level. Groups create two models—one with ice on land and one with ice in the water. As the ice melts, teams...

Growing Soil Microbes
View how microbes grow in soil. Class members first create a Winogradsky column to grow bacteria. They then set up the column of mud in a plastic bottle and include a food source for the microbes and observe the column of mud over the...
University of Waikato
Make and Use a Hydrophone
Using a home-built hydrophone, pupils investigate how things sound in water. Learners listen to sounds created in air and then compare that to the same sound picked up by the hydrophone. Individuals compare the loudness and the pitch of...
University of Waikato
Density
Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...
University of Waikato
Investigating Bubbles
Bubbles are not always trouble. Pupils investigate surface tension in water and bubble mixtures by blowing bubbles and recording observations. Learners then create bubble wands of different shapes from pipe cleaners and observe the shape...
University of Waikato
Groundwater Contamination
Scientists study how pollution occurs in hopes of minimizing its effects. A quick activity shows how point and non-point source pollution enters groundwater and aquifers. Learners mimic the phenomenon with models that show how rain...

Water Molecules in Drama
The state of molecules is changing. Young actors and actresses perform the process of phase change in front of the class. They assume the roles of water molecules and, as a group, show how the behavior of the molecules in the solid,...
University of Waikato
Hubbub Estuary
Estuaries attract people—and that can mean trouble. Learners use video and article resources to learn about the struggles of specific estuaries. They follow their discussion with an analysis of an estuary by identifying possible threats.

Solid to Liquid to Gas
Help classes understand heat as a form of energy. A hands-on activity has learners investigate how heat, or the lack of heat, affects the physical state of water. They then connect their discoveries to the water cycle.
University of Waikato
Constructing an Aquifer
Rainwater doesn't stay where it falls. Learners use modeling to demonstrate how rainwater disperses once it hits the ground. The activity includes an investigation of the height of the water table in an aquifer and how it is affected by...
University of Waikato
Ocean Acidification and Eggshells
Eggshells and seashells have a lot in common. Learners use the similarities to conduct an experiment that models the effect of ocean acidification on marine animals. Using varying levels of acidic liquids, pupils make observations on the...
University of Waikato
Building a Water Cycle
Bring the water cycle to life with in the classroom. Young scientists use household materials to create and monitor a water cycle model. They record changes in the water levels and make observations of where and how fast precipitation...
University of Waikato
Looking at Water - Solid, Liquid, or Gas
Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...
University of Waikato
Build a Marine Food Web
Dive into a lesson on marine ecosystem interactions. Individuals learn about and devise a marine food web. The resource provides organism cards and pupils use article resources to discover interactions before modeling them in a food web.

Meet the Naturalists
Studying plants is a full-time job—for some. After learning the ins and outs of phenology in the first three lessons in the unit, pupils explore the history of the science. The instructional activity highlights five historical...

Preparing for Project BudBurst
Adopt a plant and get to know its phenophases. The third instructional activity in a six-part series combines plant identification and phenology. Pupils begin by creating their own field guides to learn about the features and...

The Pollinator's Journey: Grades K-8
Bees get all the attention, but so many more creatures contribute to pollination. Scientists explore the role of pollinators as they learn about the parts of a flower and how it reproduces. They discover how plants rely on many different...

Controversy Over Wild Cats
Everyone should take an interest in the fate of wild cats. A thorough lesson explores the habitat changes of native North American wild cats and asks learners to make connections to human development. They consider the implications of...

Carrying Charges
What's all the buzz about electricity? Scholars take part in a scientific activity to test the conductivity of liquids and solutions. They first see if water, salad oil, alcohol, and vinegar cause a buzzer to buzz when electrodes are...
Aquarium of the Pacific
Ocean Drifters
Take a drift in the ocean. Class members watch a video on plankton, the drifters of the ocean. Scholars find out about the different types of plankton and sea jellies. To add a little variety, they use the aquarium webcams to study sea...
Aquarium of the Pacific
Amazing Adaptations
We can all adapt. Classmates watch a video about the adaptations of sea horses that allow them to eat and move. They then watch penguins on webcams to see what adaptations help the penguins find food, move, and avoid predators. Finally,...
Aquarium of the Pacific
Sensational Sharks
Pray that you are not the prey of sharks! The class watches a video and a webcam on sharks and make observations about the different types of sharks. Learners compare two sharks and list their similarities and differences. They then...

Fish for a Day
A short video shows how a scuba divers' equipment relates to major parts of a fish. Learners draw two fish and identify what aspects are the same and which are different. The scholars then draw a scuba diver, making sure they provide all...
