An Inventory of My Traits
Source Institutions
In this genetics meets math activity, learners take inventories of their own easily-observable genetic traits and compare those inventories with other learners in groups.
How Do Antacids Work?
Source Institutions
You just ate a big meal and feel heartburn coming on. You take an antacid and feel better. Why? Heartburn is caused by stomach juice (an acid) burning the esophagus.
Science at the Waterpark!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.
What's Your Blood Type?
Source Institutions
In this activity, learners perform a simulated blood test procedure.
What Goes Around Comes Around
Source Institutions
In this simulation activity, learners act as parts of the circulatory system and discover how it serves as a transport system for food/nutrients, oxygen, carbon dioxide and waste.
The Carbon Cycle: How It Works
Source Institutions
In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another
Modeling an HIV Particle
Source Institutions
This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.
Safe Food Preparation
Source Institutions
In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.
Engineer A Bird Feeder
Source Institutions
In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.
Cold Metal
Source Institutions
In this activity, learners discover that our hands are not reliable thermometers.
Of Cabbages and Kings
Source Institutions
This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d
It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
Name That Frequency
Source Institutions
This activity was designed for blind learners, but all types of learners can model how vibrating particles, such as in a sound wave, bump into other particles causing them to vibrate, and that the vib
Magnifying and Observing Cells
Source Institutions
In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.
Dirt Life
Source Institutions
After an interest-generating discussion about "dirt" and microbes, learners select and collect soil samples from a variety of locations (schoolyard, home, etc.).
Close, Closer, Closest
Source Institutions
In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.
Freezing Lakes
Source Institutions
In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.
Sink or Swim?
Source Institutions
In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.
Breathing Yeasties
Source Institutions
In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.
There's Always Room For JELL-O
Source Institutions
In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.
