Water Filtration

Reach into your kit & pull out the bag that says Experiment 28. Take everything out of the bag and use the bag in place of your white mat.

Place the plastic cup in the center of the white mat, and fill it a little more than halfway with cold water.

Next, grab the tube of dirt, open it and dump it into the water. Using your popsicle stick, stir the dirt into the water to mix.

Put the dirty water to the side, and place the plastic container on the center of your mat with the donut-shaped lid on top.

Next, grab one of the plastic containers, place two cotton balls in the bottom and squish them down as much as you can. Then, open the tube of quartz sand and pour a small layer on top of the cotton balls enough to weigh them down.

Place the container into the donut-shaped lid. The two pieces should connect together snug.

Then grab your next container and place the thin filter paper on the bottom. Open the tube of activated carbon and fill the container halfway. Next, connect this container on top of the quartz sand container.

Grab your third container and place one of the thicker sponge filters on the bottom, then open the tube of porcelain sand and fill the container halfway. Last, connect this container on top of the activated carbon container.

Grab your final container and place the last sponge filter on the bottom, then open the tube of crushed granite and pour it in, filling the container halfway. Then, connect the container to the container of porcelain sand. Last, place the plastic funnel on the top.

Now, grab your cup of dirty water and pour it into the funnel, only filling it halfway up the funnel to prevent it from spilling.

Now watch as the water moves through the different containers trapping the bigger pieces of dirt at the top. Watch the water that drips into the container at the bottom, its no longer dirty.
