Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.
Measuring Your Breathing Frequency at Rest
Source Institutions
In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.
Amazing Albedo
Source Institutions
In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.
Best Bubbles
Source Institutions
In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.
Statistics: Wet Heads
Source Institutions
In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.
Find the Fizz: Discover the Secret of Baking Powder
Source Institutions
In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.
Blowin’ Up a Storm of Oil
Source Institutions
In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.
Animal & Plant Cell Slides
Source Institutions
In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.
Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).
Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Plot the Dot: A Graphical Approach to Density
Source Institutions
In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.
Cooking with Chemistry
Source Institutions
In this activity, learners experiment with different variables in making hollandaise sauce to achieve the correct texture and consistency.
Sublime Sublimation
Source Institutions
In this activity, learners explore sublimation by conducting experiments with dry ice.
Measure the Speed of a Water Leak
Source Institutions
In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.
Now or Later: The "Recency/Primary" Effect
Source Institutions
In this activity (18th on the page), learners conduct an experiment to examine memory.
Glowing in the Dark
Source Institutions
In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.
Aye-Aye
Source Institutions
This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.
Linear Functions: Mystery Liquids
Source Institutions
In this math lesson, learners analyze the density of liquids in order to explore linear functions.
Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.
Egg-cellent Landing
Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.
