Fizzy Nano Challenge
This lesson focuses on how materials behave differently as their surface area increases.
In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.
Matter on the MoveAdd to list Details
Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.
In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.
Soap: Sometimes oil and water do mix!
In this activity (on page 2 of PDF), learners mix oil and water. Then, they add soap and observe what changes! The activity demonstrates how oil and water don't mix, except when soap is added.
In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.
Newspaper CollageAdd to list Details
In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.
Colors Collide or CombineAdd to list Details
Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.
M&M's in Different TemperaturesAdd to list Details
Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.
In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved
Chew that Gum
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.
Coral, Carbon Dioxide and Calcification
In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
Bubble TroubleAdd to list Details
In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.
Mysterious M&M'sAdd to list Details
Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.
In this activity (located on pages 9-14 of PDF), learners visit a cemetery to examine the distinguishing characteristics of rock weathering.
Chemistry in the Kitchen
In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the
Mixtures and Solutions
This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce
A Dissolving ChallengeAdd to list Details
In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.
