Henkel Researchers’ World Series of Virtual Science Experiments

Henkel Researchers’ World is an education initiative designed by Henkel to introduce children (ages 8 – 10) to the fascinating world of science by putting them in the role of an actual researcher.  Now, it’s your turn!

Check out the Henkel Researchers’ World series of three 15-minute science experiments on YouTube – which are all free and available for on-demand viewing. You can choose to participate at your own pace, and no registration is required. The materials you need to participate can be found in your kitchen or local grocery story. Please let your parent or an adult know that you would like to participate so they can help you prepare and conduct the experiment.

Thank you for participating, and remember to share your feedback by taking a brief survey after each lesson (Lesson 1, Lesson 2, Lesson 3).  Stay curious!

  • NEW! Lesson 3: “Is it acidic?” premieres here on Jan. 10

  • Lesson 2: A Sticky Situation

  • Lesson 1: Separating Plastics for Recycling!

Detect the presence of acids and the effects on everyday life! Here is the list of materials you need to complete the experiment:

  • 1 small dish
  • Eggshell (rinsed and dried from a boiled or raw egg) or a thin seashell such as a sand dollar
  • Lemon juice
  • Food scale (not required)

After you complete the lesson, don’t forget to answer a few questions in this brief survey!

Explore sticky adhesives that exist in nature and test their strength!  Here’s the list of materials you need:

  • Strong paper such as a manila folder or large card stock 
  • Duct tape for reinforcement
  • Paper clip or "S" hook 
  • Hole punch
  • Scissors
  • Hand wipes
  • String
  • Empty water or soda bottles as weights 
  • Variety of sticky substances such as honey, molasses, tree sap, marshmallows, or fruit by the foot
  • Popsicle sticks or butter knife for spreading sticky substances
  • Garbage bag, newspaper or a drop cloth to cover and protect the floor/table
  • A broomstick or dowel resting on the back of two chairs or something similar to create a u-frame. (Broomstick should be braced so that it does not roll off chairs.)

1. Check the list below and gather the materials you need.

2. Click video and start science fun!

3. After you complete the experiment, click here to answer a few quick survey questions and tell us what you think.

What you need for the experiment:

  • Large clear cylindrical container – like a drinking glass or vase 

  • Warm water to fill container

  • Wooden spoon – taller than the container for “stirring” the plastics 

  • Table salt or sugar

  • Tablespoon for measuring

  • Variety of empty plastics with recycling numbers from 1 – 7. You do not need all types to complete the experiment. Ask your parent or an adult to help you collect and cut plastics for the experiment. Examples to look for:

    • bags for buying fruits and vegetables at the store
    • plastic bottles and caps for beverages, ketchup, and containers for yogurt
    • balloons and straws
