Cruise ships offer many engaging opportunities for real-world math adventures. These large, floating cities use resources with numbers into the thousands place. Young mathematicians are asked to calculate numerical information...

It's all about density! Here's a dense workbook for young scientists; they solve (and show work for) 29 density word problems, including a problem where they solve for the density of Godzilla. They complete labs analyzing metal...

"Float like a butterfly, and sting like a bee" with a resource about the greatest boxer of our generation. A short biographical reading passage introduces young readers to Muhammad Ali, and includes information about his early life...

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

The challenge: determine whether a tank will float. A design activity has groups work as engineering teams in order to determine the stability of given tanks and liquid contents. The teams need to determine the equations to...

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.

How does a scuba diver control whether they sink or float? Scholars observe the relationship between absolute pressure and depth below the surface in an undersea simulation. They control the diver size and depth to center of mass to...

When a child lets go of a helium balloon, what happens to it? Does it float all the way to space? The simulator allows pupils to experiment on party balloons and weather balloons under different conditions to see what happens to them in...

Sea ice contains 17 sub-types based on age and various characteristics. Scholars observe ice floating in a simulated ocean and record their observations. Then, they view photographs of different types of sea ice and learn to...

Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

Watch young leaders as they totally rock this activity! Pupils partner up and set appointments with one another during the third in a series of 12 character-building lessons. Instructors call out the appointment time, then partners meet...

"Be the change you wish to see in the world!" The 15th and final lesson in a peacebuilding series uses this quote from Gandhi to prepare pupils for their own action projects. Individuals research a global issue, then brainstorm a method...

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...

Don't table the resource—use it now. An AP® Calculus curriculum module encourages the use of tabular data throughout the course. It provides some example topics, such as rate of change, net change, and average value of a function, where...

Motion is the focus of ten hands-on activities that challenge scholars to build machines invented by Leonardo da Vinci. Following several steps, small groups work collaboratively to recreate machines including levers, pulleys, wheels,...

Can you help Santa collect all the presents in time for Christmas Eve? A fun, clicky game prompts players to get Santa through the dangerous candy canes and into the safe path of floating gifts and stars.

The difference between sinking and floating may be a little salt. Young experimenters analyze the effect of salt and temperature on the density of water. They use their results to predict the effect of climate change on ocean ecosystems.

Use whatever material floats your boat. Working in groups, scholars decide on a type of metal and a type of coating to use for building a boat. They test their creations by leaving their boats in a pool of water for several days before...

Float across the Martian landscape. Using an online game, learners participate in teams to propel their hoverboards in a race across the surface of Mars. By correctly evaluating a numerical expression involving parentheses, individuals...

Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Students examine whether objects will sink or float.  In this buoyancy lesson students bring in objects and experiment to see if they sink or float.

Learners perform experiments to examine if debris float, or blow in the wind. The effects of these characteristics on the marine debris are then discussed. They determine how a material can influence what becomes marine debris.
