Colour Mixing Sensory Science

By Sharla Kostelyk

Learning about colours doesn’t have to be boring. Our colour mixing sensory science made for a very fun few days! Colour Mixing Sensory Bags #sensoryplay #sensorybags #sensoryscienceWe were inspired by our Rainbow theme last week and decided to extent our learning about colors into this week. There is a song that we sang (to the tune of “If You’re Happy and You Know It”):

“When you hug blue and yellow, it makes green; when you hug blue and yellow, it makes green; when you hug these two you’ll see a new color magically; when you hug blue and yellow, it makes green.”

Of course, for the next two versus, you make orange by “hugging” red and yellow and make purple by “hugging” red and blue.

We did a few easy color mixing experiments.

Colour Mixing Sensory Bags:

Supplies needed:

  • resealable plastic sandwich bags
  • red paint
  • blue paint
  • yellow paint

Instructions:

Squirt some blue paint and red paint into one bag, ensuring that the paints are on opposite sides of the bag. Do the same in other bags with blue paint and yellow paint in one and red paint and yellow paint in another.

Seal the bags, removing as much of the excess air as you can.

Discuss primary and secondary colors.

Have the child hypothesize what colours will be created when the paint is mixed.

Have the child mix the paints together with their fingers by moving the paint around through the bag. This is a great sensory activity too. The kids are able to create other colours by squishing the primary colours into each other.

You can hang the bags on the window using clear packing tape and have the child observe how the sun shining through affects the appearance of the colours.

This experiment is one of many included in the first volume of our Sensory Science Book. It is full of engaging hands-on learning designed to help kids retain what they learn because of using their senses in the process. 

Colour Mixing Mini Volcanos:

Supplies needed:

  • baking soda
  • cake pan
  • vinegar
  • food colouring
  • droppers

Instructions:

Place a layer of baking soda in a cake pan. Fill three cups a third of the way with vinegar and add about five drops of food colouring to each cup.

Fill the droppers with the coloured vinegar and squeeze it out onto the baking soda. By adding another colour on top, you can create little volcanos of new colour in mixing them. 

They loved this activity!The kids learned:

-that the best way to form a new colour was to have a person with one dropper of one colour and another person with another colour squeeze at the same time in the same area. Once left on the baking soda, the colours did not mix as easily.

-that mini volcanos are fun.

-that when you pour the three glasses of color into each other, you end up with almost black.

Mommy learned that when you do this activity, you should put newsprint down to protect your counters!!! (note that in the early picture, there was none underneath!)

The kids especially liked the look of the bottom of the cake plate after we were done and wished we could hang it like artwork. Unfortunately, a picture of it will have to do!

Some of the books that we read that were related to colour:

         

The kids also completed a great colour mixing worksheet (find it here) and had fun with some Mandala coloring pages that I printed for free from here.

They also had plenty of opportunity for hands-on learning on colour mixing with paint.

Sensory Smell Bottles

By Sharla Kostelyk

I’ve been wanting to make smell bottles for a long time. I first learned of them as a Montessori activity. They are also an amazing sensory activity for teaching about olfactory and providing sensory input. Sensory Science Smell Bottles #sensoryscience #smellbottles #sensoryplayMy kids really enjoyed this activity. Of course, boys being boys, I got to hear what other smells we could have bottled!!! How is it that boys can always find a way to find the gross factor?!

If you’re doing a unit on the Senses, this is a good way to introduce the sense of smell.

This is an inexpensive activity as you will likely have most of the supplies at home already. I found the travel spice bottles we used at the dollar store. You could also use leftover empty spice bottles if you have any.

How to Make Sensory Smell Bottles:

Supplies needed:

  • travel spice bottles
  • cotton balls
  • coffee beans or coffee grounds
  • cinnamon
  • peppermint extract or peppermint essential oil
  • lavender essential oil or lavender
  • coconut
  • lemon essential oil or lemon juice

Instructions:

  1. Put the coffee grounds or beans in one bottle, some cinnamon in another, some coconut in another.
  2. Put some peppermint extract or essential oil on a cotton ball, lavender essential oil on another, and lemon juice or lemon essential oil on another cotton ball. Place each cotton ball into a container.
  3. Have the child guess what each smell is. With younger kids, allow them to use their visual sense as well. They can look for clues such as colour and pair that with the smell to help them figure out what it is.

Help your child play “Sensory Detective”. If you print out the corresponding Smell Bottle Cards (available in the Sensory Science Book Volume 1), lay them out for your child to match the scents to.

With older kids, have the child try the activity blindfolded so that they are only using their sense of smell.

Try filling the bottles with more challenging scents to identify such as a flower, dirt, honey, pepper, salt, or orange.

Talk about what the smells are and how our sense of smell also affects what things taste like. You can find an explanation about smell and taste to share with kids here.

Note that just like all senses, some kids will be more sensitive. They may find some (or all) of the smells too strong or even offensive.

Allow them to go at their own pace. Let them hold the bottle further away or even smell through the lid. Some kids’ sense of smell is so strong that they will be able to smell it through the closed lid.

Find this sensory science activity and many more in The Sensory Science Book, full of engaging hands-on learning ideas.

Melting Ice Experiment

By Sharla Kostelyk

This is a simple science experiment to do with items you likely already have in your kitchen. Our daughter wanted to do her Science Fair project on melting ice. She was curious about what would make ice melt faster. 

This melting ice science experiment is perfect for science fairs.I thought it would be an easy at home science experiment that wouldn’t take too much planning or prep on my part, but be cool for the kids. It was pretty fascinating actually!

Melting Ice Science Experiment:

Supplies needed:

  • small Dixie cups or mini Solo cups
  • water
  • scissors
  • 6 compartment muffin tin
  • salt
  • sugar

Directions:

  1. Before beginning the experiment, have students talk about what they expect the results to be. Ask them what variable will melt the ice fastest. If you want, you can have them write down their hypothesis. 
  2. Fill 6 small Dixie cups or mini Solo cups with water. Place the cups on a baking tray and place the tray in the freezer.
  3. Freeze overnight.
  4. Cut the frozen water out of the paper cups (adult help may be required for this step). If using Solo cups, you won’t need scissors as you should be able to just pop the ice out.
  5. Place one ice cup in each of the compartments in the muffin tin. Pour hot water on one, cold water on another, steam on another, salt on another, and sugar on another.* Leave one alone so that it can act as the control.

*Adult supervision is important, particularly with the steam and hot water.

Students can document the progress through taking pictures or journalling observations at one minute, five minutes, half an hour, and one hour after adding the variables.

Here is a picture before we added anything to the ice:

ice experiment 4As you can see, the control did melt slower than any of the others. Hot water melted the ice the fastest.

Our daughter dictated to me what she had observed during the experiment and we included that as well as a picture she drew of the process and the photographs on her display board for the Science Fair. She loved presenting and explaining her findings to the judges.

Solar System Unit

Mnemonic for learning the order of the planets

By Sharla Kostelyk

There are so many inventive hands-on ideas out there to use when creating a solar system unit. It was almost as much planning this homeschool unit study as it was to teach it!

Solar System Unit Study ideas including hands-on learning and printablesI used a variety of teaching materials for this unit including the CKE Earth and Space curriculum and the online course Experiencing Astronomy.Experience AstronomyWe also borrowed several books from the library and also used a few that we own. Here are some that we used for this unit:

The New Astronomy Guide: Stargazing in a Digital Age

The Night Sky Pocket Guide

The Magic School Bus Lost in the Solar System

Space and the Solar System: God’s Amazing Creation

National Geographic Planets

Moonwalk: The First Walk on the Moon

Phases of the Moon

I try to incorporate sensory elements into all of our unit studies. For our solar system unit, I created a glow-in-the-dark solar system sensory bin and a weighted Space sensory bottle.

Space Sensory Bottle

Using a free printable that I found on 123Homeschool4Me, we brought a case of Oreo cookies to our homeschool coop and made the phases of the moon out of Oreos. The kids enjoyed this activity so much that they also did it at home a few days later. They said it was so that they could study the moon phases but I suspect it may have had more to do with the Oreos than the learning!

phases of the moon with Oreo cookiesThe kids completed phases of the moon flip books. We found the printables for those on Teachers Pay Teachers (free). I especially liked that they came in two types, one for older kids and one for younger kids. This worked really well for me with the various ages of my kids.

I used an mnemonic that I learned when I was a girl to help them memorize the order of the planets from the Sun. I know that there is controversy about whether or not Pluto is really a planet, but I had done some research and it seems that it is still considered a planet (sometimes called a dwarf planet) by those at NASA, so I told this to the kids but I included it in my mnemonic (you can click on that link or the photo below if you would like to print it off for yourself).

My Very Eyes May Just See U Now Pluto

Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto

Mnemonic for learning the order of the planetsMy kids were the most interested by what they learned in Experiencing Astronomy. It’s an online course that Einstein has been taking this year and learning so much but during the course of our solar system unit, I had all of the kids listen to the Experiencing Astronomy videos. They were intrigued and it led to many interesting discussions and learning.

At the beginning of our unit study on the Solar System, I took the kids to the Space and Science Center in the city closest to us and when we finished the unit, my mom took them there again. There is a large area there devoted to the solar system with many hands-on learning opportunities. It was a great way to reinforce their learning.

Solar System Unit Study sq.We decided to segment our solar system unit study and do a specific study on Earth. In the course of that study, these are some of the science experiments that we did:

Learning About the Earth Science Experiments

By Sharla Kostelyk

I have to say that I have found it much more interesting to teach science as a homeschooler than I did to learn science as a student. I want my kids to love learning and so in my quest to make science engaging, I look for hands-on activities that will help my kids to retain what they learn. When we were learning about the Earth, we found some awesome science experiments!

Doing these hands-on activities made learning about the Earth interesting and helped the kids to understand the concepts much better than if all of our unit had been reading out of a textbook.  Their favourite ones seemed to be the ones about natural disasters such as earthquakes, tornados and hurricanes. Personally, I found the groundwater one to be the most interesting as it was something I didn’t know before.
