Group Experiment #6

Our last group went out with a "bang."  These scientists worked on an almost identical experiment to another team.  Group #4 did a really great job of keeping the "exploding" secret to themselves.  I wanted things to be a surprise for this last set of children.  

Materials needed:  

• baking soda and vinegar (the vinegar is dyed blue)
• funnel
• test tube
• straw

Procedure:

1. Put the funnel in the test tube.
2. Pour baking soda in halfway.
3. Pour vinegar to the top of the tube (the lip).
4. Mix everything with a straw.

Predictions:  

• The baking soda will get wet and blue.
• They will both turn to a solid.
• The vinegar will get powder in it.

Some quotes form this round of experiments:

"I didn't know it would do that!"

"It's boiling!"

"I didn't see that coming."

"What's it doing?"

"I didn't even know it was gonna spill."

"Please don't blow up on my hands."

If you notice, this group followed their procedure by using a straw to mix.  This was another surprise (as you can see in the pictures) as it started again!

It exploded.  It spilled to the top.
It got the towel all wet.
The powder spilled too.

It exploded.  It was bubbly and it was cool and strong.
