Science Makes Learning FUN
Explode it.
All you need is
A Liter Bottle of Diet Coke or Pepsi
A Package of Mentos candy
Here’s How you do it:
1. Go outside in an open area.
2. Take one or two pieces of Mentos candy out of the wrapper.
3. Open the bottle of diet cola, drop a piece of candy into it, and run! Watch that thing erupt!
4. To make an even bigger geyser use warm soda, and do the experiment on a warm day. Or, drop in all the candy at the same time, put your hand over the top and shake it all up. Step back quickly when you let go. And BOOM!
Freeze it.
All you need is
Water
Small Plastic Toys
Plastic Container
Here’s How you do it:
1. Take a few blocks or hard plastic toys—little dinosaurs or Legos are good.
2. Put them in a bowl and cover them with water.
3. Stick them in the freezer until they become a block of ice.
4. Now, act like an archeologist—archeologists are scientists who study history by digging up old artifacts and mummies and other cool stuff. They have to dig out fossils very carefully, without breaking them. Use a spoon, toothpicks, and salt and get the fossils out of the ice. (The salt is a cheat. It helps the ice melt faster, but it usually takes a while to figure that out.)
Grow it.
All you need is
¼ cup Epsom salt
¼ cup hot water
Food coloring
A cup
A plate
Optional: a small jar
Here’s How you do it:
1. In the cup, measure out ¼ cup Epsom salt and ¼ hot water from the sink. Stir them together.
2. If all the salt doesn’t dissolve, heat the cut in the microwave for 20-30 seconds.
3. When all the salt is dissolved, put a drop or two of food coloring in the cup and stir to mix.
4. Place the cup in the refrigerator. Check on it every half hour or hour. Within 4 hours, crystals should form in the bottom of the cup.
5. Scoop the crystals onto a plate using a fork.
6. If you want the crystals to last longer, put them in a jar with a lid (the small jars that baby food comes in work well).
