Why is it important to measure the ingredients carefully when making slime?

To make sure the slime turns out with the right texture and isn't too sticky or too hard. 

Accurate measurement ensures the correct chemical reaction occurs, leading to the desired texture and consistency of the slime.

Which of these is a main ingredient often used to make slime?

Glue. White or clear school glue is a primary base ingredient for most DIY slime recipes

Imagine you have a toy car. What would happen if you tried to drive it very fast across a big puddle of oobleck? Will it drive quickly on top, or sink slowly into the oobleck?

The car would quickly drive on top, as if the oobleck were solid ground. 

Driving very fast applies a sudden force, causing the oobleck to temporarily act like a solid, supporting the car's weight

Is oobleck a liquid or a solid?

Both, depending on how you interact with it. Oobleck is a non-Newtonian fluid, meaning it can act like a liquid when poured slowly but like a solid when pressure is applied.

Slime is an example of a polymer. What does a polymer mean for slime in simple terms?

It's made of many tiny pieces (molecules) linked together in long chains. Polymers are large molecules made of repeating smaller units linked together, giving slime its stretchy and cohesive properties.

What do you add to glue to make it turn into slime?

An activator like liquid starch or borax solution. 

Activators like liquid starch, borax solution, or contact lens solution react with the glue to form slime.

Why is borax a very important ingredient when making a bouncing ball with glue and water?

Borax links the long polymer chains of the glue, creating a more solid, elastic structure that allows the ball to bounce.

What kind of fluid is an Oobleck called?

It is called a non-Newtonian Fluid

What happens to the tiny parts (molecules) of the glue when you mix it with the borax solution?

They link together in long chains and make a network. The borax helps the long chains of glue molecules to connect and form a strong, stretchy network, which is what makes the ball bouncy.
