Gassy Lava Lamp
Source Institutions
In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.
Choose Your Ooze
Source Institutions
During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.
Energy Sources
Source Institutions
In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.
Pollution Diffusion
Source Institutions
Learners design their own experiment to investigate how pollution diffuses through ground material.
Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.
The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
Lost Labels
Source Institutions
In this experiment, learners will conduct chemical and physical tests to identify mystery substances.
Disease Detectives
Source Institutions
In this activity, learners examine antibodies and antibody recognition using a model.
Inner Space
Source Institutions
In this activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.
Energy For Life
Source Institutions
In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.
Coral and Chemistry
Source Institutions
In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.
Food Forensics: A Case of Mistaken Identity
Source Institutions
This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.
Candy Chemosynthesis
Source Institutions
In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.
Big Things Come in Little Packages
Source Institutions
As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
Is It Alive?
Source Institutions
What does it mean to be alive? Is a cactus alive? Is a seed alive? Is the air we breathe alive? What are the necessary characteristics?
Nano Latch-n-Catch
Source Institutions
In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.
Below the Surface: Surface Tension II
Source Institutions
In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?
Can You Copperplate?
Source Institutions
In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.
That's the Way the Ball Bounces: Level 2
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.
Diffusion & Osmosis with Data Analysis
Source Institutions
This three-part lab helps learners understand the essential principles governing diffusion and osmosis.
