Rocket Launchers
Source Institutions
In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.
Comparing the Density of an Object to the Density of Water
Source Institutions
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
Watching Crystals Grow
Source Institutions
Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.
Landing the Rover
Source Institutions
In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).
Big and Little Cups
Source Institutions
In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.
Coral, Carbon Dioxide and Calcification
Source Institutions
In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.
Design a Lunar Rover!
Source Institutions
In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.
Design a Landing Pod!
Source Institutions
In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).
Weather Stations: Temperature and Pressure
Source Institutions
In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.
Let's Make a Supernova!
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.
Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
Float or Sink?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
A Degrading Experience
Source Institutions
In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.
Submersibles and Marshmallows
Source Institutions
In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.
Pie-Pan Convection
Source Institutions
It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.
From Gas to Liquid to Solid
Source Institutions
What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.
Lava Lamp
Source Institutions
In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.
Plankton Races
Source Institutions
In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.
Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.
