Hot and cold water

What will happen when you put a bottle of hot colored water in a container filled with cold water?

A technology day

This week we had a day filled with technology and grade 7 built cars, mostly out of trash. Here you see some of the beautiful cars. 

Circumference/diameter

Today we went out. After a task in Hasse Perssons book "Experiments with Mathematics", we practically learned how we are dividing the circumference of a circle with its diameter to get Pi. We did this by using a stick and a rope. Students were placed along the rope and had to count there steps in a full circle.Then they walked the distance to the pin, the radius. The radius we then doubled to obtain the diameter of the circle. When we met up in the classroom again and reflected and discussed, we were dividing the circumference by the value of the diameter and we all got the answer 3. 

We got this great practice outside!

PI

With the help of three hockey pucks and some string, you can prove the value of Pi. We did this by measuring the circumference of the puck with the help of a string.
Linn was assisting.

Linn placed the string over a number of pucks and clearly saw that the circumference of the hockey puck was the same as the diameter of three pucks and a bit more ...

The idea for this lab component comes from Hasse Persons book "Experiments with mathematics".

It is of course possible to use mouse pads, glass, rock rings or any other round object to this evidence. The circumference corresponds always a bit more than three diameters. 3,14 .................

Jumping Jack

We had technology in the 6th grade and worked on simple paper constructions. Among other things, the class made their own paper doll. Here are some results:

Look how happy pupils you get!

Invertebrates results

The paintings as grade 6 made by invertebrates are finished :) They are fantastic! It was really a fun task. With simple materials such as pieces of cloth, yarn, papier mache, and a lot of gluing they made this beautiful animals. Look and enjoy! 

Molluscs

Crustaceans

Worms

Echinoderms

Arthropods

Cnidaria

They are large circled paintings filled with animals who will decorate an entire wall at the school.
These are then hopefully for educational purposes especially for the younger students.

I am so proud of all the fine contributions!

Colored light

Grade 7 is working with salts and experimented today with colors when various salts, such as lithium chloride are on fire. To start fire we used methanol.

Beautiful!

Build a fish

A while ago I met Hans Persson and he gave me the idea to build a fish. Me and my class took the bait :) on and I was so happy and proud of the class results. Look and enjoy! 

 A perch

Evan an octopus was made.

A bream

 A cod

A mackerel

Swedish tree

Autumn is now up and running and in grade 6, we have in science started with the Swedish trees. Each student has to present a tree, both orally and in writing. They were all exploring the local area and look after their trees. Then they wrote about their tree and drew a sheet or a piece of there tree on a sheet of paper which then were laminated.These are now most known Swedish trees. 

 

Some examples of the finished tree descriptions

As for the verbal section, I encouraged students to do something different. To my delight, there were some who did that and gave us the poetry, music video and also piano-playing. 

Build a bridge

Grade 7 build bridges with glass rods. Several groups have chosen the Golden Gate Bridge, and here you see two examples soon to be ready. 

Paulina puts up the last threads.

Amanda's group challenged themselves properly and chose to build the Rolling bridge.
What a creativity and what a fantastic result!

Invertebrates

In grade 6, we work with invertebrates and in this task we are trying to get into the technology. Therefore, we all build all an animal from any of the groups of animals.
I think the result will be fantastic and look forward to the show. We have a lot of plans!

We´re using papier mache.

Some did the finger crochet.

Others were sewing.

Robins jellyfish begins to take shape.

Ellen makes the foundations of a starfish.

Victor and others were asked to make the paintings to put up the animals on.

Viktor is painting his centipede.

To be continued...

The tower

Today we used multilink cubes for solving problems. How many cubes are there in this tower?

When it became more and more difficult we came up with the conclusion that the tower did not have to be all built because it was symmetrical. We discussed ways to solve the same problem and learned from each other. 

We also had time for a little humor! Olivia did some nice goggles :)

Magic

Today we made a fun and magical experiment. We tried it last week but did not succeed very well, but after some expert advice from Hans Persson we dared to try again. Shame not to give up! 

What did we do?

Patrick poured baking soda and vinegar in a jug.

Paulina "poured" over a glass. No liquid may come down. Hocus pocus!

Then Johan turns out the light with "nothing".

Salt and water

We are working with solutions and mixtures. Today we talked about the difference between a solution and a mixture. We added sugar in hot and cold water and drew atoms and ions.
Then the class had to find out if you can resolve how much salt as possible in a glass of water.

Lucas and Samuel mixed with salt until they get a saturated solution.

We then used the salt solution to paint on black paper and came up with fine artwork.

Math words

Two and two came forward and stood in front of me, one with his face against and one with his back against. I showed up one math word and the task was then to describe the word so that those who did not see understand. When the student guesses correctly you change the place and role. Super Fun!

This exercise shows in a fun way what students have mastered and what needs to be repeated in terms of math concepts. 

Save thousand

A game with dice. 

Roll a 1-6-dice and choose the value of the dice to stand for hundreds, tens or units digit. After five types you have to be as close to 1000 as possible.

Viktor and Paula save to a thousand.
