Choose your own adventure....

Right now we are working on Chemistry goal 6.  This goal deals with understanding the difference between endothermic (energy is absorbed) and exothermic reactions (energy is released).
So I put out several salts that when mixed with water become cold (endothermic) and two that become warmer (exothermic).  Students then had to create an experiment using the salts. 
Some chose to compare exothermic reactions to endothermic.  Some students compared quantities of salts or water.
All of them created experiments and learned about different types of reactions.

More cookies?

I placed some some felt, needles and thread in front of some students.  They made cookies.
Cross stitch
Here a student is teaching himself how to use tinkerCAD.

The science of cooking

Some tasty no bake cookies in Makerspace.
That's right the science hot plate doubles as a stove top.
We have the recipie if anyone is interested.

We went to the Academy.

Today the entire 8th grade department went to the Academy of Science located in the Science Center.  Patrick and I told our story of how we started making in our classrooms.  Terrie and Eric talked about their student centered Electricity unit.

Terrie explaining the exploratory portion.
Eric lighting a student built light bulb.  The filament is graphite from a pencil.
Thanks Uncle Chris for the opportunity.

How do kids handle failure?

Mr. Dempsey has Stephen in discovery and I have him in science.  Last year he was given the opportunity to work on a 20% time project with Don and Melissa.  During this time he created fishing lures.  Which then turned into an online business.  Right now he is working on a new bait.  He designed a fish using a free web based design tool.
Here it is printing.
The completed mold.
The failure.  Notice the black melted part.
In this picture there was warping of the plastic and the clamp that he used crushed the mold.  The real story behind this was the conversations afterwards:

Stephen:  Yeah, it was really weird. It cooled at the two ends but not in the middle.
Me:  Why do you think that was the case?
Stephen:  Well its thinner there and its away from the pouring source.
Me:  What are the molds normally made out of?
Stephen:  Metal normally.  That's why I need a cnc machine.
Me:  What are you going to do next?
Stephen:  Well I think we need to print the fish out.  Then I can make a plaster of paris mold from it.

Failure didn't stop him.  It gave him answers.  It directed him to new solutions.

Don't go changing.....

Yesterday and today we set up several chemical reactions.  Students were looking for:

A color change
A temperature change
A gas evolving
A precipitate forming
Or light

Zinc in Copper Sulfate- color change
Epsom salt and washing soda- precipitate.
Calcium Chloride, Baking soda, and water- temperature change and gas evolved.
Bromethyl Blue and Carbon Dioxide- color change

Sorting through reactions.

Today we talked about the difference between physical and chemical changes.  Kids first did a free sort and then a guided sort.

I cut up a piece of paper into paper dolls.  Physical
I then burned them.  Chemical

What have you printed?

A student in Mr. Rachal's class used tinkerCAD to design a sarcophagus.  So cool.

Stay on Target

Chemistry Learning Target 4: Students will use changes in energy to describe volume changes within various states of matter.
Students are using an app called Explain Everything to explain everything with this target.  With the app you can add pictures, text, drawings, and record your audio explaining what is happening on your slides.
Students recreating and recording an experiment that they found on the internet to explain the goal.
Typing how changes in temperature change the volume of a gas.

Audience is Everything

Student: I am making a tissue box guitar.
Me: That's cool.  When you finish it I would love to send it over to my daughters preschool.  They are exploring sound and building instruments.
Student: Man, I had better do a really good job on it.

This blog is called Makerspace so.......

It's amazing to see all these kids making.
Studying some drawing techniques.
Creating some bookends.
Robots: a Lego launcher and a cheetah.
Crayon art is a favorite.
Sewing a phone case.
Trebuchet- in case we get attacked by gnats.  Which has a good possibility of happening in my room.
