Celebrate National Science Day

national science day

Celebrate National Science Day at your school by getting your students involved in activities ranging from worksheets to experiments. Take the day to teach your kids how to build their own volcano or send their own messages to each other in invisible ink. You can also download our free science printables worksheets to help teach your students about science in between experiments. Read our blog to help you prepare your classroom for National Science Day!

Science Printables:

Certain subjects are sometimes better explained visually. Science is one of them. Personally, we think these various printable science worksheets would be beneficial to any classroom. From weather flashcards to a clear breakdown of photosynthesis, these science worksheets are undoubtedly useful classroom tools. Test your student's knowledge on the basic parts of the body or see how well they know animal groups. If nothing else, the educational crossword puzzle should help keep kids busy!

Classroom Science Experiments:

Some students learn better from being able to actively get involved in class. National Science Day is the perfect excuse to get your class involved in hands-on educational experiments that can be controlled in the classroom. Follow the steps below and recreate volcanic activity or even try making invisible ink.

Volcanic Activity Experiment:

Materials:

  • Tablespoon
  • Baking soda
  • Vinegar
  • Flour
  • Warm water
  • Plastic bottle
  • Dishwashing soap
  • Food dye
  • Pan
  • Salt
  • Cooking oil
  • Cup

Project ideas adapted from Explorable

Procedure:

Step 1:

Create the volcano by taking the cup and tablespoon for measuring the ingredients and mix together 6 cups of flour, 2 cups of salt, 2 cups of water and 4 tablespoons of cooking

Step 2:

Once the mixture is smooth and firm, start to mold the mixture into the shape of a cone, and mold it around the empty soda bottle. If it’s not smooth enough, make sure to add more water in the mix as you begin to mold the cone shape. Make sure you don’t mold over the mouth of the soda bottle as this opening will function as the mouth of the volcano.

Step 3:

Once the mold is completed, fill the bottle halfway with warm water and a few drops of food dye. Too simulate lava, use the red food dye. Add 6 drops of dishwashing soap and 2 tablespoons of vinegar.

Step 4:

Finally, pour the vinegar in the mouth of the volcano, take a step back, and watch it explode. You and your class just made a chemical reaction that simulated the actions of an erupting volcano!

Invisible Ink Experiment with Milk:

Materials:

invisible ink milk

Procedure:

For this experiment, you will be using the milk as the ink and the cotton swab as the pen. Use the cotton swab to write a secret message on paper and wait for the milk to dry. Let the messages sit for about 30 minutes. Finally, expose the hidden message to heat by using a lightbulb from the adjustable desk lamp, which will cause the writing to reappear.

Invisible Ink Experiment with Lemon Juice:

Materials:

  • Lemon
  • Water
  • Bowl
  • Spoon
  • Cotton swab

Procedure:

Start by cutting the lemon in half and squeezing the juice from one of those halves into a bowl. Add a few drops of water to the bowl and stir the juice and water together with the spoon. Use the cotton swab as the “pen” by dipping the tip into the bowl and writing a message on a piece of paper, the message will disappear as the paper dries. The message will only reappear when you or the person you wrote the message for holds it to a light. These invisible ink science experiments will have the whole class feeling like secret detectives!

We hope you found these printables and experiments fun, and useful in celebrating National Science Day! Tag us on Twitter (@Bostitchoffice) with your finalized experiments!
