Change in Temperature: Endothermic Reaction
Source Institutions
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.
Chemistry in the Kitchen
Source Institutions
In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the
Getting Windy
Source Institutions
In this activity, learners create and understand surface currents. Learners create example surface currents and discover how landmasses affect the current.
Density Rainbow and the Great Viscosity Race
Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.
Thermal Energy Put to Work
Source Institutions
In this activity, learners determine whether thermal energy can be used for work.
Weather Stations: Phase Change
Source Institutions
In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.
Magnet Races
Source Institutions
In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.
Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
Effects of Solar Radiation on Land and Sea
Source Institutions
In this activity, learners explore the different heating properties of soil and water.
Disappearing Statues
Source Institutions
In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.
Wave on Wave
Source Institutions
In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.
Twirling Rope Frequency
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record
How Do We Convert Electrical Energy into Mechanical Energy?
Source Institutions
In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.
Using Solar Energy
Source Institutions
In this activity, learners discover how solar energy can be used to heat water.
Static Spoons
Source Institutions
In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.
Geothermal Power Plant Model
Source Institutions
In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.
Sniffing for a Billionth
Source Institutions
This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.
Hanging Around
Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.
