In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.

In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

In the related activity called "Colors Collide or Combine," learners are intrigued by the apparent "line" that forms where colors from M&M coatings meet but do not mix.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.
