Video – Will 3-D Printing Change the World?

You can design your own projects and Mrs. Soo will help you print them on our school’s 3-D printer.

Here’s what you need to do:

  1. Go to Tinkercad.com
  2. Create an account. It is best to have an adult put in their birthdate to avoid complicated emails.
  3. Complete the tutorials.
  4. Start tinkering!!
  5. When you have completed a project send the file via email to Mrs. Soo at [email protected]
  6. Just for fun check out Thingiverse.com to get some ideas!

Dandelion Seed Parachute

Dandelions have the coolest seeds. They are designed by nature to fly very far away from the dandelion plant. Why do you think this is?

Video of seeds blowing away

Your challenge is to design something that looks like a dandelion seed and see if you can get it to float if you drop it from a chair.

Don’t forget that if it doesn’t work you might have to redesign it many times before it floats. Every time it doesn’t work you learn something new about the design.

HINT: You do not need a lot of materials, a piece of paper will work.

You will need an adult to help you drop it.

Dandelion Science

Dandelions are everywhere!

Let’s Observe:

  1. Find a dandelion and watch it for the next few days. Do you see any insects visiting your dandelion?
  2. Look at your dandelion in the morning, do you notice that it is closed?
  3. When does it open? Why do you think it closes up at night and opens in the day?
  4. Look at the bright colour. Why do you think it is so bright?
  5. Look at the stem. Does it remind you of a straw? What do we do with a straw? How do you think a dandelion uses its stem?

    Look at this straw and this dandelion stem.

Let’s Experiment:

*Experiment worksheet can be downloaded fromĀ here.

  1. Question: Does a flower stem suck up water?
  2. Materials: Dry Dandelions and Container of Water
  3. Process:
    1. Find one or more dandelions with long stems and pick them.
    2. Take the flower head off and split the stems from the bottom up into 2 strips using your fingernail.
  4. Hypothesis / Guess: Before you put the stem strips into the water, guess what you think is going to happen.
  5. Put the stem strips in a sink or container full of water.
    1. Observe: What happens?
    2. Why do the stem strips move and change like that? What do you think is happening?
    3. Conclusion: Explain what happened and did it answer the question, Does a flower stem suck up water?

Once you have discussed your thoughts, read this:

The reason that the stem strips curl when you put them in water is because the outside of the stem does not let the water in and the inside of the stem absorbs the water.

Feel the difference between the inside and the outside of the stem. Can you feel how the inside is moist? This is how it delivers water from the roots up to the flower.

Solar Oven

How does a solar oven work?

Solar energy is when radiation from the sun, otherwise known as sunlight, is converted into heat or thermal energy.

A solar oven directs the radiation (sunlight), using tin foil, into a box that has a black bottom that absorbs the heat. The box is insulated with saran wrap to trap the heat.

Experiment *Best done on a warm, sunny day

Questions:

Will the solar oven get warm enough to melt food?

Will the inside of the solar oven get warmer that the outside air surrounding the solar oven? How much warmer?

Hypothesis or Guess:

What do you think will happen? Answer the questions above before you do the experiment.

Materials:

  • Pizza box or shoe box
  • Saran Wrap
  • Tin Foil
  • Tape
  • Scissors
  • Black paper
  • A chop stick or stir stick or skewer
  • An oven thermometer, if you have one
  • Food to cook, for example, cheese on crackers, chocolate on a cookie or a glass of cold water

Procedure:

  • Cover the lid with tin foil, with the shiniest side facing out
  • Cover the bottom and the sides with a black or dark coloured paper or material
  • Prepare the food that you wish to cook and put in the box
  • If you have an oven thermometer, measure the temperature outside the box before you start. You might have to leave the thermometer for 5 minutes to get a good reading, then record the temperature
  • If you have an oven thermometer put it inside the solar oven and leave it there
  • Cover the top of the box with saran wrap and tape up any holes
  • Put the box in the direct sunlight
  • Use a stick to prop the lid open at an angle that allows the sun to be reflected directly into the bottom of the box
  • Keep an eye on the oven to make sure crows don’t eat your food but leave it for about 30 – 60 minutes

Conclusion:

  • What happened to the food inside your solar oven?
  • Did the food melt?
  • Did the water get warm?
  • If you had a thermometer what was the temperature inside the box at the end of the experiment?
  • How many degrees warmer was the inside of the box than the outside?
