In this activity, learners experiment with different variables in making hollandaise sauce to achieve the correct texture and consistency.

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

In this activity, learners explore sublimation by conducting experiments with dry ice.

In this chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.

In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

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

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

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.

In this activity, learners use simple materials to create giant bubbles.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra
