Participants joined in on the hands on fun guided by Dinosaur Dan with erupting volcanoes and making silly putty. “Science can be made fun for all ages” said Dan. Again, it was a great experience for all.
Did you know that every magnet has a north and a south pole. When you put a north pole against a south pole, the poles attract; however, if you try to put a north pole against another north pole, the poles repel one another. Give it a try and let us know the results of your experiment!
Sedimentary rocks form thanks to the process of erosion. Wind, water, and ice slowly break apart all types of rocks turning it back into soil, or sediment. As the soil is being deposited from the wind and water on the ground, layers are formed called strata. The sediment builds up and the weight and pressure causes the particles to start sticking or cementing together to make sedimentary rocks. These rocks have layers in them from the sediment that made them. The layers at the bottom are older than the layers at the top because they were deposited first.
Supplies you will need:
- 8 oz. plastic bottle with cap
- Playground sand
- Food Coloring (assorted colors)
- Plastic container with lid (to mix colors)
- Plastic spoon
Instead of purchasing pre-colored sand, you can actually make it at home by following these simple steps:
- Using a plastic container with lid, add 1 cup playground sand. Then add 10-12 drops of food coloring. Add more drops of food coloring to create the desired color.
- Secure lid and shake container. Within one or two minutes, the sand particles will absorb and take on the new color.
- Repeat this process for each color desired.
NOTE: You may want to allow the sand one day to dry otherwise you may find the colors will blend and turn brown once layered within your bottle.
The bottle is going to be the outside of the rock that holds the sediment strata within. Use a plastic spoon to scoop the sediment (colored sand) into the funnel that is placed into the top of the bottle. Using one color at a time, you will make different, colorful layers of stratifications.
Be careful not to shake the bottle up once you have started making your layers because all of the colors will start to combine and it will turn your rock brown.
You can also use different materials or types of sand including:
- Pea gravel
- Regular playground sand (without color)
- Black sand (Silica sand)
- Crushed sea shells
- Miniature marbles (only with older children)
- Rock salt
Baby food jar
Pastina (can substitute instant mashed potato flakes)
Experiment: Weather Jar
1. Fill the jar with water about ¾ full
2. Put a few pieces of pastina or mashed potato flakes in the jar
3. Place Aka-seltzer tablet in jar and immediately put the lid on
Watch weather happen before your eyes! See thunder by using pastina (notice how they look like clouds). The pastina will dance up and down simulating the event of thunder as cold air pushes warm air down. You can substitute instant mashed potato flakes for the pastina to create a more dramatic weather event. While it also simulates thunder, it will look like a snowstorm in the jar!

Dinosaur Dan visited pediatric patients at Mission Hospital in Asheville, NC on November 12. The children had a fun time making space mud that they were able to keep. Every child that is a patient at Mission Hospital is welcome to attend a High Touch High Tech fun hands on science activity every Wednesday at 3
