Countdown Reaction

Reach into your kit and pull out the bag that says Experiment 3. Take everything out of the bag and place it around the white mat. Then, place the empty bag back in your box.

The bottles of liquid are color-coded. Start by matching the blue bottle with the puffy starch. Then match the green bottle with the little vitamin c tablet.

First, let’s start with the blue bottle. Uncap and remove the seal. Drop in the puffy starch, if it doesn’t fit, simply squish it a bit to make it smaller.

Next, screw on one of the squeeze lids tightly and shake it for 10 seconds.

Now, let’s setup the green bottle. Just like before, uncap, remove the seal, and this time, drop in the Vitamin C. tablet. Screw on the other squeeze lid and shake for 10 seconds.

Next, grab the round petri dish and place it in the center of your mat.

Next, twist to open the top of the blue bottle. Gently squeeze, and fill the measuring cup with 12.5ml. Pour the liquid from the measuring cup into the petri dish.

Next, let’s do the same thing with the other bottle. Twist to open the top of the green bottle and fill the measuring cup with 12.5ml.

Pour the liquid from the measuring cup into the petri dish. Wait about 10 seconds to see the reaction. It turned blue!

Pour the blue liquid from your petri dish into one of the empty cups provided and repeat the steps above to watch this reaction again. You can even spray the destain into the petri dish to make it change back to clear.

Now, clear your workspace and place the two empty cups in the center. Let’s see what happens when we do this same experiment in cups.

Start by filling the measuring cup all the way up with the liquid from the blue bottle. Then pour all the liquid in your measuring cup into the large empty cup.

Repeat the same steps with the green bottle. Fill the measuring cup all the way up then pour it into the last empty cup.

Mix the liquids together by pouring one cup into the other. Do this back-and-forth three times.

Now, let’s count to see how long it takes for the reaction to happen!

Finally, let’s try it again but this time with different amounts. This time, fill the entire measuring cup with the liquid from the blue bottle and pour it into the other empty cup.

Next, only fill ½ of the measuring cup with the liquid from the green bottle and pour it into one of the empty cups.

Now let’s mix them together three times and start counting, just like before.

Now let’s try it once more. This time fill only half of the measuring cup with the liquid from the blue bottle and pour it into an empty cup.

Then, fill the entire measuring cup with the liquid from the green bottle and pour it into the other empty cup.

Now mix the cups together again three times and start to count. Do you notice changes in the timing this time? This time it happened much slower!
