🧪 Science with Sarah: Moondough and moon phases

Hello parents, teachers and students! If you’re looking for a fun way to understand simple machines, this experiment is for you.

Be sure to check out GMSA@9 on Wednesdays, when Meteorologist Sarah Spivey demonstrates and explains the science behind it.

HERE’S WHAT YOU’LL NEED

• 1 cup cornstarch
• 1/2 cup conditioner
• Bowl
• Spoon
• Mason jar or round cookie cutter
• Plastic knife

MAKE THE MOONDOUGH

• STEP 1: In a large bowl, combine the cornstarch and conditioner
• STEP 2: Initially, use the spoon to mix the ingredients, then use your hand to fully incorporate

• STEP 3: If the mixture is too sticky, add a little more cornstarch. Your finished moondough should be pillow-y and moldable.

SHOW THE PHASES OF THE MOON

• STEP 1: Using the top of a mason jar or a round cookie cutter, cut out a circle from the moondough
• STEP 2: Using the plastic knife, cut out the phases of the moon
