In this activity, you will encrypt a message for your students or children. The message will divulge the location of one or more hidden treasures. THere are many ways to encrypt messages. this lesson will suggest two, but you are encouraged to get creative and fidn other ways to encrypt the messages you give to your students or children.

Compare how the dominios hitting other dominos are similar to chain reactions that happen in nuclear fission

This activity is broken into two parts, in the first part students will build a structure (shake table) that will test to see if the strucutre will withstand an earthquake. In the second part, students will design a building that is stable enought to survive an earthquake.

Create a giant foaming reaction and wow your friends with the classic science demonstration! With just a few simple ingredients, you can make something that looks like toothpaste being squeezed from a tube -- but so big, it must be for elephants!

Help your students understand one way to harvest energy from biomass -- by fermenting a plant-based sugar!

In this science activity you will examine circular objects and see what you can discover about their sizes. As you explore, you might be surprised at how useful the results can be -- maybe it will inspire you to save up for a bike with bigger wheels!

With all the frustration you might have endured coping with dead batteries, it might surprise you how easy it is to make one out of household materials. Try out this activity, and it might just charge up your imagination.

If you were to dig a big hole straight into the Earth, you would notice the temperature getting warmer the deeper you go. This is because the inside of the Earth is full of heat. The heat released is called geothermal energy. In this activity, students will build their own geothermal power plant. The steam made from this activity will turn a toy pinwheel.

The half-life of an isotope is the time on average that it takes for half of the atoms in a sample to decay. As an isotope decays, it can transform through a number of elements until they end up as a stable isotope. In this activity, candy will be used to demonstrate the process of “half life”.

Science is super cool -- especially when ice and salt are involved. Supercool water to below its freezing point and then discover how to make ice on demand in this experiment.

How do you know when a chemical reaction has occurred? This experiment will help you learn the indicators of a chemical reaction.

Learn about the elements used to create the spectacular colors seen in firework celebrations. Color your own firecracker, then use paper and a straw to design a system to launch your firework.

This STEM activity will give students a chance to explore the invisible and strong attractive force called magnetism and work with magnets like some researchers at INL.

Imagine this challenge: You have two glasses of water -- one empty and one full. You want to pour half of the full glass into the empty one. The twist? You aren't allowed to pick up either glass! Can you get the water to "walk" between the glasses using nothing but a paper towel? Try this activity to find out!

Have you ever wished your drawings would come alive and the stick figures or objects on your paper could move around? What sounds impossible is actually not! In this activity, you will make your drawing more around be letting it float on water. What makes this possible is the interesting chemistry of dry erase markers.
