Secret Formulas: Paste
Paste
is not to taste,
nor does paste
make waste.
Here's the trick:
Paste makes
things stick!
First have your student experiment with the sticky quality of several materials: salt, baking soda, wheat flour, rice flour and corn starch.
Have him rank them from the stickiest to the least sticky.
Then have him pic 5 spoonfuls of at least two substances of his own choice to mix together to make his own paste.
Then have him pic 5 spoonfuls of at least two substances of his own choice to mix together to make his own paste.Then test the sticking quality of his secret formulas
by gluing a bean to a card.
Does it hold?

Students eagerly investigate the properties of substances as they make their own personal brands of paste, toothpaste, cola, and ice cream. The activities have been designed to convey key science/mathematics skills and concepts, provide motivating real-life experiences with chemistry, and build comprehension of cause and effect, central to later understanding of controlled experimentation. Secret Formulas speaks to the need expressed by many primary school teachers for more high-quality physical science activities.
