Experiments

Soil Sammy

Here's what you'll need...
  • Plastic bottle cut in half horizontally
  • Handful of soil
  • Nylon stocking
  • Teaspoon of grass seed
  • Scissors
  • Decorative craft supplies (i.e. pipe cleaners, feathers, googely eyes, etc.
  • Hot glue gun and glue sticks

This simple science project is a fun, inexpensive alternative to a Chia Pet. Decorate Sammy to your heart's content and then water your grass seed to grow green hair.

A Soil Sammy is a great ecology project for all ages! Children plant the grass seed, care for their Soil Sammy by providing sunlight and water, observe the growing grass, and decorate their own plant container.

Once you have assembled and prepared all of the necessary materials begin by rolling the stocking to the seam. Sprinkle the grass seed into the bottom of the stocking, and then place a handful or a cupful of dirt into the stocking. The soil and seed in the stocking should be about the size of a fist.

Acetone Art

Here's what you'll need...
  • Acetone (around 1 cup)
  • Wide shallow container
  • Spoon
  • Plastic baggie
  • Scissors
  • Safety glasses
  • rubber gloves
  • Wax paper
  • Covering, if using plastic table

What’s more fun than using chemicals to destroy stuff? Using chemicals to destroy stuff AND make something cool!

Acetone is great at breaking down polymers, those long chains of atoms that make up plastics. It’s used as the active ingredient in nail polish remover for that very reason! More concentrated acetone, which is sold in hardware stores and used as a cleaner and paint thinner, can dissolve Styrofoam (polystyrene foam) quite quickly. We can use this fact to make some cool decorations.

Acetone isn't good for your skin (it can dry it out) and would be really bad to get in your eyes, so the first things you'll need (besides adult supervision) are gloves and safety glasses.

Simple Circuit

Here's what you'll need...
  • light bulb (preferably from a flashlight)
  • copper wire
  • battery
  • tape (electrical tape is recommended, but masking or scotch tape can also work)
  • an adult helper

This week we are going to investigate electricity by making a simple circuit.

We'll need just a few simple supplies - a lightbulb (a flasglight lightbulb is recommended, some copper wire and a battery. An adult friend is also handy because he or she can help us experiment safely with electricity. :)

First, let's take a look at the cooper wire. You need to make sure that some of the copper part of the wire is showing. If not have an adult help you strip the wire so you can access the metal inside of the wire.

Corn Starch Plastic

Here's what you'll need...
  • corn starch
  • water
  • vegetable oil
  • sandwich baggie
  • spoon
  • microwave-safe plate or bowl
  • microwave oven
  • dropper (optional)

Plastic bottles, plastic spoons, plastic packaging, plastic bags… we use a lot of plastic. Plastics are made from polymers, which are super long chains of atoms. We love them because they’re cheap and super sturdy for how light they are. The problem is that they’re so sturdy that, after we throw them away, they can sit around in a landfill for a million years! Almost all plastics we use come from petroleum products, but recently more is being made from corn, and you can make some corn starch plastic at home!

Mix equal parts water and corn starch into a sandwich baggy. About a tablespoon works well, which is two large spoonfuls of each. If you’ve made oobleck before, this mixture should look familiar, except that this will be more watery. Next add 2-3 drops of vegetable oil and mix that in.

Grow Your Own Crystal Garden

Here's what you'll need...
  • clear cup for the crystals
  • cup for mixing
  • measuring spoon (normal spoon works well)
  • stirring rod
  • Mrs. Stewards Liquid Bluing
  • Ammonia
  • salt
  • spongy material (sponge or peice of charcoal)

This week, let’s learn how to make your very own salt crystal garden. That’s right we are going to grow salt! While we are not making new salt we are going to use the salt to make crystals.

First, we will need to make our growing solution. Take a spoon full of Mrs. Stewarts Liquid Bluing (can normally be found in the laundry detergent isle at most stores), a spoon full of salt, and a spoon full of ammonia and mix it in a cup. The portions do not have to be exact, but it should end up being a one-to-one-to-one ratio. This means, there should be the same amount of bluing agent as there is ammonia as there is salt.

Mix this solution together for about a minuet. The goal is to dissolve as much salt as you can but do not worry, all of the salt will not dissolve.

Traveling Flame

Here's what you'll need...
  • a candle
  • match or lighter
  • eye protection
  • an adult helper

Our experiment this week is a very simple science experiment that you may have conducted and never even noticed!

You'll need a candle, something to light the candle and an adult helper since we are doing a fire experiment. Also, we recommend putting on a pair of safety glasses and doing your best mad scientist laugh.

For the experiment we're going to light the candle and then blow it out. Now here's the cool part! Once you've blown out the candle, you'll probably notice smoke coming still rising from the top. Strike another match and place the flame near the smoke. You might see the candle suddenly light again!
