Awesome Science Experiments for Kids

If you enjoy doing hands-on educational activities with children, you are going to LOVE my new book, AWESOME SCIENCE EXPERIMENTS FOR KIDS. It contains over 100 colorful and creative STEAM activities for kids ages 5-10. I wrote it with parents and grandparents in mind so the instructions are simple and the experiments only require supplies you probably already have at home!

Turn your mini scientists into true artists by creating a pendulum painting work of art using a classic chemical reaction.This makes for an impressive science experiment or science fair project for kids. The end result is a beautiful, vibrant, and unique masterpiece the kids will love creating.

LEGO Ice Rescue

To begin our LEGO ice rescue we gathered the following supplies:

Be a superhero and rescue the LEGO ice minifigures from drowning in freezing water using science! Learn why salt melts ice and engage in imaginative play.

A few hours or days before you want to do this experiment make some ice using the silicone LEGO ice mold. You can either make regular clear ice or add some food coloring to the water before freezing to make colorful LEGO ice minifigures like we did!

Ice LEGO Experiment

Once we had our supplies gathered we followed these instructions to play superhero!

  • Drop the ice LEGO minifigure into a cup of cold water. (The colder the water the longer your LEGO guys will last before melting!) Notice how the ice floats on top.
  • Place the piece of string or yarn across the top of the LEGO ice.
  • Sprinkle some salt on top of the string and ice. Be generous with the salt. Wait for one minute.
  • Pull the string out and see if your LEGO ice minifigure comes with it!

Were you successful rescuing your LEGO ice guys? If not, what else can you try?

Be a superheroe and rescue the LEGO ice minifigures from drowning in freezing water using science! Learn why salt melts ice and engage in imaginative play.

We did this experiment several times using different kinds of thread, string, and yarn to see what worked best. We varied the amount of salt we sprinkled and varied the temperature of the water. Keep track of your observations!

Fishing for LEGO ice minifigures opens up a whole dimension of imaginative play in addition to being an educational science activity. The kids created all kinds of scenarios where their LEGO guys fell into the water and they had to be rescued. This is one of our all-time favorite science experiments!

The Science Behind Fishing for LEGO Ice

When salt is mixed with ice it lowers the freezing point. Usually water freezes at 32° F (0° C), but when it is mixed with salt it lowers the freezing point significantly. This simply means the ice melts. You may have noticed that in the winter people sprinkle salt on their icy stairs and walkways to make the ice melt. We have used this same trick to make yummy treats like fruity ice slush and easy homemade ice cream!

When salt is sprinkled over ice it melts. However, when it is used in such a small amount, like in our experiment, the water around the ice freezes again quickly. This means that the string gets trapped as the water around it refreezes, thus making it stick to the ice. Isn’t that cool?!
