Cabbage Juice Indicator
Source Institutions
In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.
Turning the Air Upside Down: Warm Air is Less Dense than Cool Air
Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.
Cup Towers
Source Institutions
In this activity, learners explore different ways to stack cups to meet a personal goal.
Hot & Cold
Source Institutions
In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.
Seasons and Shadows: Investigate How Shadows Shift Throughout the Year
Source Institutions
In this activity you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer?
What is Blood Pressure?
Source Institutions
In this activity about heart health (on page 34 of the PDF), learners measure their own blood pressure using an electronic blood pressure monitor with a self-inflating cuff (included in cost of materi
Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.
Moving On Up: Capillary Action 1
Source Institutions
Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.
Production of Carbon Dioxide
Source Institutions
In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.
Special Effects: Titanic and Beyond
Source Institutions
In this activity, learners investigate how geometry plays a role in perspective.
pH Scale
Source Institutions
In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
Changing Shadows
Source Institutions
In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.
Save Your Skin
Source Institutions
This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.
Roller Coaster Design
Source Institutions
This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.
The Effects of Acid Rain
Source Institutions
In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.
Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
Fun with Flatware: Little Experiments to Try at the Dinner Table
Source Institutions
This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.
Capturing Carbon Dioxide
Source Institutions
In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.
Neato-Magneto Planets
Source Institutions
In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model
Electric Cup Guitar
Source Institutions
Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.
