The acid-base reaction is the most classic and children's favorite chemical kids science experiments among many interesting children's chemical science experiments. Today, Alpha Science Classroom teaches kids how to create a magic chemical reaction car. With the simple materials, we will explore the mysteries of the most amazing chemical science experiments and help kids become chemical wizards.
Alpha science classroom: how to make a Chemical Reaction Car Supplies
Water bottle (square one is best)
1 bamboo skewer
4 plastic caps
4 pony beads
Glue gun or other glue
Alpha science classroom: How to Build the Chemical Reaction Car
Step 1: Kids need to warm up the glue gun. caveat! The glue gun is very hot and requires adult supervision! If necessary, other glues can be used.
Step 2: Children carefully insert the hot tip of the glue gun into the center of the water bottle cap and melt a hole in it.
Step 3: Children cut the paper straw in half, and then use scissors to cut the bamboo into two pieces, which are 1 inch longer than the straw.
Step 4: For each wheel, glue the pony beads to the center of the wheel.
Put some glue in the middle of the pony beads, and then insert one end of the bamboo.
Step 5: Children insert the bamboo into the paper straw, and then glue the other end of the bamboo glue to another wheel.
Step 6: Children repeat steps 4 and 5 with the second axis.
Step 7: Children use tape to stick two paper straws on the bottle like a shaft.
Step 8: Children use tape to stick two paper straws on the bottle like a shaft.
Children need to unscrew the water bottle and pour 1 cup of vinegar into the water bottle. Then cut into 5-inch x 4-inch rectangular tissue paper, and pour 1 tablespoon of baking soda. Roll up and fold the ends so that the baking soda does not fall.
Go outside now! The children quickly put the bottle upright! Insert the baking soda package into the bottle and close the cap.
Shake the bottle and place the wheel on the ground.
Alpha Science Classroom: The scientific knowledge behind the chemical reaction car
The alpha science classroom tells the children that this chemical reaction vehicle contains excellent chemical science and engineering technologies. First, children must use wheels (a simple type of machine) to make cars. Next, the children's car needs some power! Make it a chemical reaction to make it roll. When baking soda (a base called sodium bicarbonate) and vinegar (an acid) are mixed, they react and release carbon dioxide (CO2). The pressure in the bottle accumulates from CO2 and escapes through the hole in the bottle cap. The force leaving the roof creates an equal and opposite force in the other direction, causing the car to roll. Children, do you understand?
Is the Chemical Reaction Car made by children very cool? This is a fun kid's science experiment. Children will not only enjoy the fun which brings by science but also help children to learn the most basic chemical science knowledge. We make the education fun, develop children's imagination and let children explore more secrets about the acid and base reaction.
Alpha science toys are preparing a lot of chemical science experiment kits, we are creating a magic world which is full of a chemical element. Hi Children, come with us and choose more interesting science toys.
