I hope you enjoyed Science Week . I had fun hosting great guest bloggers and focusing on only one subject for a whole week. What other weeks would you like to see us tackle?
When it comes to science I usually let my kids lead with questions and suggest we investigate from there. One morning last week my son didn’t finish his milk and I asked him to please pop it in the fridge so he could have it with his lunch. Instead he asked if he could put it in the freezer to see what would happen. Of course I was game. After he put it in the freezer I asked him what he thought would happen. At 6 it was no shock that he thought it would freeze, so I asked him how long he thought it would take. That sparked this simple kitchen science experiment we did a few days later. My kids love kitchen science for kids and I love doing it with them. Fun together time with science!
Our question was: Which kitchen liquid would be the first to freeze ?
- Gather your materials. You will need an ice cube tray, a line up of different kitchen liquids , a timer ( not really a must ) and a freezer. We had a measuring spoon too! Our liquids were water, vinegar, chocolate syrup, ranch dressing, dish soap, milk and apple juice.
- Start by filling your tray with the different liquids. Before you ask your kids to make predictions ask them what they already know about the different liquids. My kids and I noted that we freeze water all the time and it takes an hour or two. They noted that milk will freeze so they knew that more than just water can freeze. After they go over all their background knowledge ask them to make a hypothesis or prediction if you are focusing more on results not the reason for the results. If they make a prediction simply say “why do you think that will happen?” and voila you will also get a hypothesis out of them.
- Freeze it! We set my iPhone timer to go off at regular intervals.
- Observe what is happening. The apple juice was the first to form crystals. The water quickly caught up by the next time we checked. The dish soap had cool bubbles and was getting harder to stir, and the chocolate still tasted great although it wasn’t really ever frozen. We checked on the tray for 3 hours and by then end of that everything was solid except the chocolate syrup which still has a dough like texture days later.
- After the results are in ask your child what they noticed. My daughter noticed that the vinegar and water froze pretty easily and that the chocolate never did. My son noticed that the thicker liquids were much slower to freeze than their thinner counterparts. That’s when I jumped in with the word viscous. We talked about how the water, milk , vinegar ,and apple juice froze faster because they all have lower viscosity than the dish soap , ranch dressing and chocolate syrup. I kept it very simple explaining that the less viscous a liquid is the easier it is to take another form and for the cold to get to every part of it. The thicker liquid was harder to freeze because the cold air had to work harder to get all of it cold enough to freeze. I tend to over explain things to my kids and have learned their signals for when my answer is shifting into a lecture. If they keep asking questions keep answering them but those blank stares are a sure fire sign that you should keep it simple, at least for now!
The best part about simple kitchen science for kids is that it lets your children see that science is everywhere. It’s in their kitchen and is accessible to all.
Tomorrow we are talking about how teach the scientific method to young kids with Jillian from A Mom With A Lesson Plan!
We love to play with vinegar and baking soda at our house . We explored it with squirt guns, at a play date and even pretending to be mad scientists. This time we made potions but really we just made a really awesome fun mess! We made these after school this week and already my 2 year old has asked to make so many I am out of vinegar and baking soda. Kids love to pretend and mixing imagination with scientific inquiry is a great way to get them interested in asking questions and testing their theories out. We pretended we were making love potions but not the way that maybe a teenager would think about it. Instead we were making potions to make everyone feel loved, not to fall in love with us and even that fell by the wayside . Bottom line, have fun and make sure you have towels ready!
- Gather your materials. You will need some baking soda, vinegar and then we added food color and food flavoring ( strawberry and cherry) . You will want clear containers, spoons, and whatever you need to protect your house from food color.
- Set out the ingredients and let them explore. While they started I talked about how some people think that potions and spells will make people fall in love and they both thought that was crazy talk! We pretended we were making people feel love but soon they just got into making a potion and the love bit was lost. This is fine the goal wasn’t to teach about love potions so much as simply explore.
- My son saw the baking soda and immediately got excited about the prospect of a fizzy overflowing potion. Only he couldn’t remember what made it bubble and discovered it was not the cherry flavoring.
- My daughter followed her brother’s lead and absolutely adored every minute.
- Once they figured out it was the vinegar they made potions over and over. In all different color combinations and with as much excitement every time. It soon turned into making predictions about if it would overflow or not.
A science experiment for kids should be fun and I don’t think my son could have had more fun than he did with this mash up of two classic summer activities. He is all about squirt guns and backing soda volcanoes are a constant favorite here. Using your child’s interests to make learning fun is such a fun way to make your child eager to learn. If squirt guns are not welcome in your play then you can use eye droppers, turkey basters and even bath toys instead. Make sure after the activity you wash the squirt guns carefully to get all the vinegar out so there are no accidental squirts at someone later.
- Gather your materials. You will need a pan ( ignore the mini muffin tin, that was our first attempt and well obviously it didn’t work. It was too hard for a 5 year old to get a good aim on such small targets), baking soda, vinegar , food coloring, a large measuring cup or bowl , protective eye wear and squirt guns.
- Start by adding food coloring in random dots to your pan.
- Cover with baking soda.
- Fill your squirt guns with vinegar. The easiest way to do this is to submerge the squirt guns in a bowl or large measuring cup full of vinegar.
- Get ready – go outside! Make sure the protective eye wear is on . Ask your child to make a prediction about what will happen.
- Shoot !
- He loved the colored bubbles – he had no clue there was food coloring under the baking soda.
- He stepped closer to get the harder to aim at areas.
- It was super fun to see all the colors emerge and even mix together .
- After the guns were empty his sister was invited out to do some pouring too.
We’ve been having fun with recycled materials and a few days ago when I heard my son say ” I’m bored!” I replied with ” Want to throw some eggs off the porch? ” He’s 5 so of course he said yes! I told him there was one rule we had to make a escape pod and try to protect the egg from cracking.
- Gather your materials. We rummaged through our recycle bin, my art closet and playroom. This is what we decided we might use. Immediately there was talk of a parachute. When I found a treat box it was quickly tagged as a possible parachute. We also used bubble wrap, an egg carton, some tape, cotton balls, party streamers and yarn. Use what you have that’s the whole idea, to use what you have to make something useful to protect the egg .
- First he lined the carton ( that we cut in half) with cotton balls and bubble wrap and added strips of party streamers.
- Then we poked holes in the treat box to make a parachute and threaded yarn through.
- Tied it on to the carton.
- Added the egg. Closed it up and used a little tape too.
- Then we trekked out to the porch and …. wait wait first we made predictions. My son predicted it would be OK. I thought it would be smashed. Then he dropped it .
- It didn’t crack!
- ” Let’s do it ’til it cracks!” OK!
- 2nd time it hit the flower box … as soon as it did my son said ” I bet that made it crack!”
- He was right. I asked him to explain why it would make it crack but the ground wouldn’t. He explained it simply but logically. ” The parachute didn’t have time to help yet and it hit hard.”
This wasn’t a planned activity but it was a blast. It would be so fun in a class to keep throwing them until only one survives!
