21. Static Electricity Hair

Overview:

Want to provide your kids with (literally) hair-raising good time? It’s super simple to teach your kids about static electricity with this easy, no-mess science activity.

What You need:

  • an inflated balloon
  • a piece of cloth

Steps:

Rub the surface of the balloon with the cloth for at least40 seconds. Then, hold the balloon a short distance above your head and watch your hair stick to it!

What’s Happening:

The balloon gains electrons from the cloth and becomes negatively-charged when you rub it together. Then, when the balloon touches you hair, it attracts your hair, which is positively charged.


22. What’s That Mystery Object?

Overview:

The process of using your sense of touch is very important to the scientific method. In this experiment, you’ll use your sense of touch to see how many different textures you can recognize.

What You Need:

  • A grown-up or friend to help
  • A blindfold
  • A “feely” bag that you can’t see through

Small objects from around the house that have different textures, such as: a plastic bag, a water bottle, a banana, a piece of paper, a cell phone, a rubber ball, a cotton ball, a tooth brush, a washcloth, etc. Try to find objects of different materials like velvet, wool, cotton, leather, metal objects, wooden spoons or toys, pieces of aluminum foil, and other interesting objects and textures.

Steps:

First, put on your blindfold. The next step is to have a grown up or friend put a mystery object in the bag for you to fell. Can you guess what each object is?


23. Sugar Water Rainbows

Overview:

This science experiment is especially meant for older kids, but it can me modified for kids of all ages. Your kids will love this colorful experience about density and buoyancy, and all you need are some common household ingredients.

What You Need:

  • food colorings (preferably in rainbow colors including red, orange, yellow, green, blue, purple)
  • water
  • a clear straw
  • salt or sugar
  • 6 cups
  • tablespoon

Steps:

First, fill each of the cups with the same amount of water.

Next, add the food coloring, one color in each cup, preferably in rainbow order.

Line the cups up next to each other.

In the first cup, do not add any sugar at all.

In the second cup, add one tablespoon of sugar.

In the third cup, add two tablespoon of sugar.

In the fourth cup, add three tablepoons of sugar, and so on.

Stir each mixture until all the sugar is dissolved in each glass.

The next step is to make a sugar rainbow by placing the end of the straw in the first cup (the cup with no sugar), only about a half of an inch.

Cover the top of the straw with your thumb before lifting it out of the water so that the water does not fall out of the straw.

Now dip the straw into the second cup (1 tablespoon sugar). This time, insert it deeper so that the end is one inch below the water level. In one quick move, release the thumb and recap again. Now you should have two layers of color.

Keep dipping the straw into each solution from the one with the least sugar to the one with five tablespoons of sugar. Each time, the straw is inserted half an inch deeper.

What’s happening?

Density is the amount of substance (mass) within the volume occupied by the object. If two cups have the same amount of water (i.e. same volume), the one with more sugar is denser than the one with less sugar.

Buoyancy is determined by relative density. The solution with less density floats above the solution with higher density. That is why the color don’t mix.

Sugary water has higher density than plain water. The solution with more sugar has higher density than the one with less sugar. If you have inserted the straw in the solutions from the least sugar to the most sugar, then the color don’t mix and you have a sugar water rainbow.


24. Painted Nature

Overview:

In this activity, kids will be closely observing natural phenomena, looking for signs of life and growth, and using their senses to experience natural materials. These skills are extremely important scientific foundations.

Steps:

First, have your child search for natural objects in nature. Fill a bag with interesting sticks, leaves, rocks, twigs, pebbles, and anything else you can find.

Next, bring them into the “classroom” or home to closely observe and paint them.

As you paint, you can discuss the natural colors and features of these objects: What is their texture? What do they notice about each object?

Variation:

My kids love “melty crayons”. They can’t get enough of them. Gather several rocks and heat them up in the oven. Then, carefully draw on them with crayons. The heat of the rock will melt the crayon wax and the it will go on like paint.


25. Magnet Dump

Overview:

This activity is a great introductory magnet activity, and for younger kids, they’ll be practicing skills of classifying and sorting.

Steps:

First, dump out a selection of metal objects onto the table.

Next, ask your kids to help you “clean up” by using the magnets to pick up different objects and sort them into containers.

Discuss which objects are attracted to a magnet and which are not. What patterns do they notice? What other objects would they like to try?


26. Magnet Magic

Materials:

  • Clear plastic box (look in your recycling bin)
  • Pipe cleaners
  • Scissors
  • Magnet

This super-easy experiment is a really fun way to teach your child about magnets in a colorful, magical way, and it only requires simple materials from around the house. 

First, cut up several pipe cleaners and place them in a clear plastic box. The box does not need to be fancy, just see-through.

For your first time through this demonstration, have your child take a magnet and touch it against the surface of the plastic box. They’ll find that the pipe cleaners are lifted up and move with the magnet!

What’s Happening?

Magnets attract certain types of metal. The pipe cleaners have a thin strip of metal, so the magnet is able to attract those pieces and pull it around the box.

Extension: Next time, think of what other objects could you place in the box? What objects do you predict the magnet could move around?


27. LEGO Boats

Overview:

This experiements present a great opportunity to get kids thinking about engineering and design.

Steps:

First, challenge your kids to build their own boat out of LEGO bricks. For an added challenge, only give them a certain number of pieces.

Once everyone has finished building, put the boats to the test in a tub of water.

Add pennies a few at a time to see how many each boat can hold.

Talk to your kids about how weight and design matter. Reflect on good designs and help them understand why they worked well.


28. DIY Parachute

Overview:

You can learn about gravity by making a DIY parachute for a light-weight toy. The parachute is easily made from materials around your house, and you can experiment with different strategies and objects.

Materials:

  • Plastic Bag (i.e. grocery bag)
  • Yard/String
  • Paper Cup
  • Scissors

Steps:

First, use the scissors to remove the handles from the plastic bag. Next, poke four holes around the plastic bag so that they are the same distance apart and on opposite sides of the bags.

Then, cut four holes into the rim of the paper cut.

You’ll also need to cut four pieces of yarn, 10-12 inches long. Thread one piece of yarn through the hole in the plastic cup and tie the yarn to the cup with a knot. Repeat with all four strands of yarn in the remaining holes.

Next, thread the other end of the pieces of yarn through the hole in the plastic bag and tie a knot. 

Finally, personalize and decorate your cup with stickers, paint, crayons or markers.

Now it’s time to find a toy that is going to take a ride in your parachute. Launch your parachute into the air and see what happens!

Experiment with putting different objects into the paper cup and see how it affects the parachute’s effectiveness. Does the parachute flight time increase or decrease?

You can also try creating the parachute with different materials to replace the paper bag, such as a paper towel or napkin, and see how that affects the performance.


29. Magic Milk Experiment

Materials:

  • Full Fat Milk
  • Food Coloring
  • Dawn Dish Soap
  • Cotton Swabs

Steps:

First, pour the milk in a small baking dish until the bottom is covered. Next, fill the milk with drops of food coloring. Glitter is optional!

Then, pour some dishwashing soap into a bowl, and dip your cotton swap tip into the dish soap to coat it. Then, gently touch your cotton swab to the milk and watch what happens!

Milk is composed of minerals, proteins, and fats, which are easy to change. When you add the dish soap to the milk, the soap molecules try to attach to the fat molecules in the milk.

When everything stops moving, you can see where all the fat molecules are.


30. Steel Wool & Vinegar Reaction

This experiment will make abstract concepts like “chemical reaction” and “rusting” become more clear and concrete.

Materials:

  • steel wool
  • vinegar
  • two beakers
  • something to cover the beaker (paper or a lid)
  • Thermometer

Steps:

First, place the steel wool in a beaker. Then, pour vinegar onto the steel wool and let it soak for about a minute.

After a minute or so, take the steel wool out and shake off any excess vinegar.

Next, wrap the steel wool around the base of the thermometer and then place them both in the other beaker.

Then, cover the beaker with paper or a lid. It’s important that you keep the heat in.

You’ll want to make sure that you can still read the temperature on the thermometer. It’s a great idea to poke a hole if possible through the covering so that the thermometer can fit through it, and you can easily read the temperature.

Make a note of the initial temperature, and observe it for about five minutes.

What’s Happening?

You will see that the temperature on the thermometer gradually rises, and the beaker will likely get foggy. When you soaked the steel wool in vinegar, it removed the protective coating on the steel wool, allowing the iron in the steel to rust.

Rusting is actually a chemical reaction between iron and oxygen (or oxidation). This is the chemical reaction that creates heat, thereby increasing the temperature of the beaker and on the thermometer. This is an examples of an exothermic reaction (a chemical reaction that releases energy in the form of heat).


31. Corn Syrup Viscosity Experiment

Overview

This experiment could not be simpler, and it’s the perfect tool for teaching kids of any age about viscosity.

Materials:

-Corn Syrup

-2 glass containers (one should be smaller than the other)

-cupcake pan or 3 small bowls

-Food coloring

-Dropper

Steps:

First, fill the larger glass container 1/2 to 3/4 full with corn syrup. Then, add the small glass container to the center. Careful! The corn syrup will rise a bit when you do this.

Next, Use a cupcake pan or 3 small bowls and put in a small amount of corn syrup. Mix each one with a food coloring of your choice. You should have three separate colors of corn syrup.

Then, put some colored corn syrup in the dropper, insert the dropper into the clear corn syrup and add the coloring in different places. Do that for each color as many times as you wish.

Now, you can turn the smaller glass jar while holding the outer glass still. The colored syrup will start to spread a bit. Now, switch direction and turn the small glass jar back to its original place. The colored dots return right back to their original form.

What’s Happening?

Corn syrup has a viscosity that is 5,000 times that of water, so they don’t mix in the same way.


32. Homemade Play Dough

Overview:

This is a classic DIY project, and kids of all ages will love it.

Materials:

  • 3 cups of flour
  • 1.5 cups of salt
