Flying Ghosts: Observing, Predicting, and Testing

DSC03425

This science-math-arts lesson starts off with the following story.

Now we all know that there are no ghosts in real life, but we can make ghosts out of paper.

Once upon a time there were three little paper ghosts. (Cut out a paper ghost) like this one. These ghosts just loved to fly around. Each had a special way to fly. The first ghost would spin round and round as he flew. (spin you hand)The second ghost loved to zip back and forth as he floated. (wave hand back and forth) The third ghost like to jump up and then come straight back down feet (or sometimes) head first. (drop hand fast) One day they decided to teach each other how to do each one’s special flying technique. But try as they might they always flew in their own special way.

Why do you think that was so?

PROCEDURE

WOW A story followed by a demonstration of flying paper ghosts

OBJECTIVES Children will observe, ask questions, make predictions, and design tests. They will group and  graph their test data. CCSS.Math.Content.K.MD.B.3 CCSS.Math.Content.1.MD.C.4 CCSS.Math.Content.2.MD.D.10

MATERIALS Half sheets of typing type paper, pencils, scissors, paper clips, chart paper.

How will you make your paper ghost look?

OBERVATION

During the story, cut out a ghost shape while noting that since ghosts are imaginary, they can be any shape we want them to be. Purposely make yours oddly shaped. Now let the ghost fly by holding it over your head and letting go.

QUESTION

  • Next ask: How did it fly? Have them share their observations. Repeat several flights. Does it always fly in the same way? How could we change the a ghost flies? What shape do you think would spin? What would make it fall faster?
  • Record their ideas of other ways to make the ghosts.

Paper ghosts can be any shape.

TEST

Give out paper and scissors and let them test their ideas by making ghost shapes and letting them fly. (Provide an open area like a rug or outside for the testing). Put out paper clips for those who want to try adding weight.

Let go and see how it flies.

RECORD DATA

Make several columns on chart paper, board, or an interactive white board. On top of each columns write a way to fly such as spin, flip, float, and drop, Have extra columns to add any other moves they observe. After each test they should put a tally mark in the column that best matches how their shape flew most often. For preschool, you can have them place their ghosts in the proper column using tape or lay them out on a chart on the floor.

CONCLUSION

Study the graph. Count tally marks or ghosts. Study their shapes. What did we learn about how paper ghosts fly? Which shape spins the most? Which floats? Does the paper clips change how it flies? Does size make a difference? What other tests could we do?

EXTENSION 

Explore making ghosts with different size and types of paper.

STEAM IT UP

Infuse the arts by suggesting they make a collage using their ghosts.

How do you think this ghost will fly?

Sunflowers: A Science & Math Observation Lab

sunflower headScientists use their senses to observe and formulate questions.

In this lesson a first grade class observes sunflower heads.

WOW [Wonderful Object of Wonder]: 5 large sunflower heads and 1 sunflower still on its stem.

Objectives:  Children will name their senses and then use them to make observations and create questions (Linguistic, physical, cognitive, and creative development). Children will estimate the number of seeds in a flower head and then count them. They will estimate the height of the sunflower plant and measure it (Common Core: CCSS.Math.Content.1.NBT.A.1; CCSS.Math.Content.1.MD.A.2)

Presentation: Sit children in small groups and set a sunflower head before them. Ask the following questions and allow time for every child to share his or her ideas several times.

OBSERVATION

What can we observe about sunflowers?

…with our eyes

  • What colors do we see?
  • What shapes do we see?
  • How many do we see?

looking

“The seeds are striped.” “They’re white and black.” “And gray and brown.” “The leaves are green and brown.” “There are yellow things like cups where the seeds have fallen out.” “There are fuzzy things on the seeds.” “There’s thousands of seeds.”

…with our fingers

  • Is it wet, dry or both?
  • Is it hard, soft, smooth, bumpy or all of these?
  • Does it stay together or fall apart?

touching

“Feels hard and bumpy.” “Loose. the seeds are loose.” “The brown part on the outside falls apart.” “Ugh. This part is wet.” “I can put my finger through it.” “Feels curvy like a funny shape ball.”

…with our noses

  • Does it smell strong or not very much?
  • Does it smell like something you have smelled before?
  • Does it smell nice or yucky?

Smelling

“Smells like chocolate milk.” Like dirt.” “Tickles my nose.” “Smells fuzzy.” Smells like a rainy day.” “Smells like wet paper.” “Good. It smells good.” “I like how it smells.” “Yuck. I don’t think so.”

…with our ears

  • Without moving or touching it, does it make any noise?
  • Does it make a noise when you touch it?
  • When might it make noise?

listening

“I don’t hear anything.” “It’s quiet.”  “It’s just sitting there.””It crinkles when I touch it.” “It’s like dead.” “Sounds like paper.” “It would make noise in the wind, I think.”

ASK QUESTIONS

DSC03419Solicit questions: Next gather child-generated questions and list on board or chart paper.

  • Is it alive? (the seed)
  • How does it get so big from such a little seed?
  • How tall is it?
  • What are these little yellow and brown flower things?
  • How many seeds are there?
  • Do they blow over in the wind?
  • Can we plant them [the seeds] now?

how tallMAKE PREDICTIONS

Have children make predictions for each question

TEST

Together with the children devise tests and do research to find the answers to the children’s questions.

For example: Set up a center where the children can remove all the seeds from a sunflower head and count them. At another center put out the different measuring tools and the sunflower on its stalk to find out how tall it is. Provide cups and dirt and plant some of the seeds to find out if they are alive. Put out books about sunflowers and find information on the web.

RESULTS & CONCLUSIONS

After all children have had an opportunity to explore the centers, share what they have learned, have them share with the whole group.

NEW QUESTIONS

Find out what new questions they have and make a list.

  • Draw pictures of the sunflowersDSC03422
  • Make up a sunflower song or poem or story
  • Do a sunflower dance
  • Make sunflower seed pictures
  • Pantomime a sunflower seed growing into a sunflower plant

SUNFLOWER FACTS

  • The scientific name for a sunflower is Helianthus., which is Greek for Sun Flower.
  • They are one of the fastest growing plants.
  • The tallest sunflower was 25.6 feet tall.
  • The sunflower is native to North America and was used as food by the Native Americans.
  • Each sunflower head is made up of 1000 to 2000 flowers which turn into the seeds.
  • The sunflower is a heliotrope, which means it follows the sun as it crosses the sky each day.
  • Oil is made from black sunflower seeds. Snacks are made from white striped ones. You have to crush break open the outer shell to find the edible seed inside.

Being a Scientist: Sensory Observation Lab

DSC03323

Setting up a sensory observation lab

We are born scientists. From birth children can see, smell, hear, touch, and taste.  Observations made with our senses are the foundation of scientific inquiry. So that is where we start…

This activity can be done with children of any age. With very young children, it works best and is safest when an adult sits with one child and models the actions alongside them. When working with a large group provide enough objects so that no more than two children have to share an object. Record observations on chart paper or board. If children are old enough to write their own observations, use the worksheet instead.

  1. Choose something to observe: This should be something that will attract children’s attention. Do not hesitate to choose something familiar, but do make sure it has an intriguing sensory element. Some suggestions: A beet fresh pulled from the garden; a fossil rock; a flashlight; a hermit crab; a clear glass of water
  2. Place the object on a surface that highlights or contrasts with it and the surrounding surface so that the eye is drawn to it, such as a piece of paper, a tray or mat.
  3. Gather your children around the object and ask questions like the following that focus on the sensory elements.

Sensory Observation Questions

SIGHT Before touching look at the object

  • What colors do you see?
  • What shapes do you see?
  • What lines do you see?
  • Are there any special markings?
  • Does it move?
  • What is unique about it?
  • How do you think it feels?
  • How do you think it smells?

TOUCH Pick up the object and rub fingers over it

  • is it rough or bumpy or smooth or both??
  • Is it hard or soft or both?
  • is it wet or dry or both?
  • Is it sharp or dull or both?
  • Does it have moveable parts?
  • What other textures do you feel?

SMELL Pick up and hold object about 2-4 inches from the nose

[Safety note: Demonstrate how to hold the object about 2 inches from the nose and gently wave the palm over it to fan the odor toward your nose. Emphasize the danger of inhaling any unknown substance]

  1. Is the odor strong or weak?
  2. Is the odor sweet or bitter or sour or acid?
  3. Does the odor remind you of something else you have smelled?

HEARING Listen to the object

  1. Does it make a noise on its own?
  2. Does it make a noise when you touch it or rub it?
  3. Does it make a noise when you shake it or turn it?

TASTE Put object down. Do not taste or put near mouth

[Safety note: Warn children against putting anything in the mouth during a science lab unless they are working with an identified food item that has not been handled by others]

  • Why do you think you should not taste this object?
  • How do you imagine it might taste?

Coming to a Conclusion

Summarize the observations using the recorded observations. Ask one or more of the following questions.

  • What do you think it is?
  • What other things can you name that are like it?
  • Do you know this object so well that if it were mixed up with the others you could find it again?

EXTENSION ACTIVITY

Mix the objects together with other similar ones and see if the children can find the one they observed.
