Science Experiments

1. Miss Dodenhoff - follow along and do it at home with your family - a cohesion experiment with water and food coloring

You will need:

• 7 plastic cups (or anything that holds water)

• 6 paper towel sheets

• Food coloring - red, blue, and yellow

Directions:

Line the 7 cups in a straight line. Fill cups 1, 3, 5, and 7 with water. Put 3-5 drops of red food coloring in cup 1, 3-5 drops of yellow food coloring in cup 3, 3-5 drops of blue food coloring in cup 5, and 3-5 cups of red food coloring in cup 7. Mix the food coloring in the water (use separate spoons). Then fold or roll paper towels (make it so the paper towels are as long as possible). Finally, put the paper towels in the cups (like the picture above). Wait 2-3 hours...and see what happens!!!!

2. Miss Dodenhoff - What happens when you pour milk & food coloring onto a plate then dip a cotton ball of dish soap in the middle?

You will need:

• 1 plate (larger is better, with raised edge)

• Food coloring

• Milk (just covering the bottom of the plate)

• 1 cotton ball or Q-Tip

• Dish Soap

Directions:
Pour milk onto the plate. You need to cover the bottom. Then put drops of food coloring in the milk. Use a couple colors, 1 drop at a time, keep the majority of the drops on the outside of the plate. DO NOT MOVE THE PLATE. Then dip cotton ball or Q-Tip into dish soap. Place the cotton ball (or Q-Tip) in the center of the plate.

WATCH WHAT HAPPENS.

Explanation is in the video!

3. Miss Dodenhoff - Can you make colors reappear after you mix them?

You will need:

• 1 large clear glass/cup of water

• 1 small cup/glass of cooking oil

• food coloring (several colors is best)

• 1 spoon

Directions:
Fill a large clear glass with water - about 2/3.
Pour some cooking oil into a small cup/glass. Drop several drops of food coloring into the cooking oil (more color the better). Mix the food coloring and cooking oil with a spoon. Notice the color it turns. Now, pour the cooking oil and food coloring mixture into the clear large glass. Wait a few seconds and watch what happens!!!!

4. Miss Dodenhoff - Can an image you draw with expo marker dance in water?

You will need:

• a glass bowl or dish (with an edge)

• expo marker(s)

• water

Directions:
Use an expo marker and draw an image on the bottom of the glass. The image MUST be connected by lines. Then wait for 10-15 minutes for the image to dry.

After 10-15 minutes, you will need to pour some water into the bowl without the water touching the image. To do this, tip the bowl so the image is at the top and the water can collect on the bottom. Once you have enough water, you begin to SLOWLY lower the bowl until it's flat on the table. Hopefully your image lifts off the bottom of the bowl and is now floating! Swirl the water around carefully - not touching the image - to make it move and dance!

EXPLANATION:
Expo markers write using pigment (color) and alcohol. When you draw an image and let it sit for a while, the alcohol evaporates leaving just the pigment behind. As you add water to the bowl, and slowly begin lowering the bowl to the table, the water is able to seep under the pigment and lift the dried pigment off the surface. This is how you can make your image dance!!!!!
