Hot Stuff!: Investigation #4
Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.
Dripping Wet or Dry as a Bone?
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.
Acid (and Base) Rainbows
Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.
Hot Stuff!: Investigation #1
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.
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.
The Rumblin' Road: Determining distance to a ThunderstormAdd to list Details
In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.
How Can Gravity Make Something Go Up?Add to list Details
In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.
Good News: We're on the Rise!
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.
The Straw FluteAdd to list Details
In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.
Acid Rain Effects
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
What's Hiding in the Air?: Acid Rain Activity
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.
In this activity, learners build a sled kite that models a type of airfoil called a parawing.
This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.
Lung CapacityAdd to list Details
This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.
In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.
Feeling PressuredAdd to list Details
In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.
Imploding Pop CanAdd to list Details
In this dramatic activity/demonstration about phase change and condensation, learners place an aluminum can filled with about two tablespoons of water on a stove burner.
Physics in the Sky: Physics on a Plane
On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.
Crunch TimeAdd to list Details
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
Percentage of Oxygen in the AirAdd to list Details
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
