To Eat Or Not To Eat, That Is The Question

I do not know about you, but I will be boiling a lot of eggs over the next few days. The problem is that when I get busy, I tend to forget which ones are boiled and which ones are not. There must be a way to use science to figure this out so no one ends up with a raw egg on the egg hunt!

Let’s get started!

Remember to ask an adult before you do this experiment.

Materials

• 1 hardboiled egg
• 1 raw egg
• Plastic egg filled with plasticine or silly putty
• Plastic egg filled with water

Procedure

1. Examine the two eggs…

  “Why do we have to read so much in here?” I have fielded this question from students several times over the years. By the time my students reached high school, many were disillusioned with reading. They found it tedious, challenging, or boring.

Egg Drop Design

With Spring Break just a week away, I thought it would be best to continue on with my egg theme. As the holidays approach, I know I will have to be bringing quite a few eggs home (not just to eat, but experiment with too, of course). This has me thinking about how best to protect an egg. I want all of you to put your thinking hats on and try this experiment with me. Send me a note to let me know your results as well.

Let’s get started!

Remember to ask an adult before you do this experiment.

Objective

Can you design a system that will protect an egg from…

Bunnies Hopping Around

As April is already here, I am getting pretty excited about the holiday that is fast approaching. You know, the one where the bunny drops off those delicious chocolate treats at your house for you to enjoy!

I have to say my holiday was almost ruined when someone told me that the Easter Bunny does not exist! I think this is because they have never seen the Easter Bunny hop by their house. Well, just in case you do not have an Easter Bunny hopping by your house to deliver some eggs, this week I thought we should make our own hopping bunnies as a backup. I just cannot go without my…

Static Electricity Butterflies

Static electricity is a fascinating subject — I was going to say shocking, but I had some groans earlier when I used that line! This time of the year, I am finding that everything is either sticking to me, or my hair is sticking straight in the air. I seem to carry an extra charge or two around I think. None the less, those shocks you get while walking around the house involve science so…we had better investigate further.

Let’s get started!

Remember to ask an adult before doing this experiment.

Materials

• Balloon
• Tissue paper
• Card stock paper
• Small piece of cardboard
• Pencil
• Scissors
• Googly eyes (optional) – See https://en.wikipedia.org/wiki/Googly_eyes
• Glue stick

Stretchy Water

Water, what an amazing substance. Yes, I know I have said this before, but is so much fun (not to mention inexpensive and often messy) to investigate the properties of water.

Did you know water has the ability to stretch itself out and not break? How can that be… well, we better investigate further. Let’s get started!

Remember to ask an adult before doing this experiment.

Materials

• One clear glass
• Water
• Lots of pennies or other coins of the same type

Procedure

1. Fill the glass full of water, make sure you get it as full as possible. To do this, set it on the flat surface, get down at eye level and look…

Static Electricity

I do not know about your house, but it is SO dry around mine. The other day as I was getting dressed, my clothes were sticking to me like a magnet and sparking like lightning! Not to mention what it does to my hair — without even trying it sticks straight up in the air.
Of course, the explanation of what is going on can be found in science; static electricity to be exact.

Let’s investigate further.

Float or Sink

I was rearranging things in my office the other day, and I ran across a box of materials that made me a bit nostalgic.
Sometimes teachers invite me into the classroom to do presentations and I wanted to share with you one of my favourite games I play with students – Float or Sink. You will be amazed at the results.
