Mirror maze and writing

Summary
Write your name or draw your way through a maze while looking in a mirror.
Science topic (2005 curriculum connection)
Physical Science: Light and Sound (grade 4)
Materials
  • shoe box with a separate lid; one end of the box folded inwards
  • small mirror and tape
  • mazes and other written challenges, laminated for repeated use (see attachment)
  • dry erase pen and tissue to erase
Procedure

Print the challenges:
Print out the attached pages double sided, then cut the sheets in half to make challenges on each side of the two sheets. Laminate.
Each sheet will then have a maze on one side, and a written challenge on the other.
When the written challenge is read in the mirror it says either "DRAW A FACE" or "WRITE YOUR NAME".

Prepare the shoebox:
Remove the lid and tape a small flat mirror near one edge of the lid.
Open up one short side of the box and tape flat, to make an opening on one end of the box.

Show students how to set up the activity:
Clip the chosen maze or challenge to one end of the support board.
Place the opened-up box on its side, and place the board and maze inside. Place the edge of the lid under the other end of the board, so that the board holds the assembly in place (see first photo). If the lid still falls over, place a supporting box behind it.
Make sure the box is oriented to enable left- or right-handed drawing on the maze through the opened box side.

Students sit behind the box and look over it into the mirror, to see the reflection of the maze/challenge in the mirror. They should not look directly at the maze (though some will not be able to help themselves).
While only looking in the mirror, use the dry erase pen to solve the maze or challenge. It is hard, but a fun challenge for most students.

Discussion:
Students can describe their experiences. They will find that moving the up and down movements of the pen are reversed in the mirror - when the pen is moved towards you, in the mirror it appears to move further away, and vice versa.
This effect happens because the straight rays of light are reflected in the mirror.

Mirrors

Summary
A series of activities using mirrors.
Curriculum connection (2005 science topic)
Physical Science: Light and Sound (grade 4)
Procedure

Students are told what the challenge is at each station.
Students freely experiment at each station with minimal guidance, so that they can make their own discoveries.

Discuss discoveries and pull out key concepts on light reflection (and angles for older students).

End the lesson with building a kaleidoscope each.

Notes

Science Club did three activities: Mirrors for looking round corners, Mirror symmetry patterns, Kaleidoscope.
New York After School programs did more.

Rock Cycle

Summary
Move through the rock cycle doing activities for each stage.
Curriculum connection (2005 science topic)
Earth and Space Science: Earth's Crust (grade 7)
Materials

Materials in the chosen activities. Plus a piece of (local) sedimentary rock e.g. sandstone, mudstone, ideally showing layers. Plus a piece of (local) igneous rock e.g. basalt for extrusive igneous and granite for intrusive igneous (with magnifiers). Plus, if available, some pretty metamorphic rock showing contrasting folded layers.

Procedure

Draw mountains on the board and an ocean.

Students sit in a circle around an erosion activity demonstration.
Discuss, while adding to the drawing, how rocks are weathered and eroded, washing particles into the ocean.
The valley formed can be discussed, but end on the layers of sediment building up in layers on the 'ocean floor'.

Students model their own sediment layering with the first step of the sedimentary uplifting activity, stopping after students have made their layers in the tray. Note how the layers undulate - they are not straight, just like the sediment layers on the ocean floor. (Don't let students shake or dig in the tray.)
While they do this, circulate with a piece of sandstone and mudstone, to show the layers (and maybe plant fossils). Students can feel the graininess of the rock but see that it has been so compressed with the pressure of sediments adding above it, that the layers are welded into a solid piece of rock.

Referring to the rock cycle drawing, and adding to it, tell students that a couple of things can happen to these sedimentary layers.

They can be pushed back up to the surface of the earth as tectonic plates move together, to uplift into mountains (add arrow to drawing).
Students return to their sedimentary uplifting activity, to push up the sedimentary layers, and then circulate to draw the shapes seen in the folded layers.
Show students images of sedimentary rock formations, and recognize some of the same shapes.

Or sedimentary rocks can be pushed deeper into the earth, where they are compressed further into metamorphic rock (add to drawing). This rock can also be uplifted - show a piece of metamorphic rock with crinkled layers if available.
If metamorphic rocks are pushed even deeper towards the molten centre of the earth, they heat up enough to melt. Melted rock is called magma.

Some magma comes to the surface fast when a volcano erupts, and cools rapidly on the surface to extrusive igneous rock (add to drawing).
Show basalt, a local extrusive igneous rock.
Other magma moves more slowly upwards inside the earth so that it cools slowly to form intrusive igneous rock (add to drawing). As it cools, there is time for the different kinds of mineral molecules to organize together to make crystals.
Distribute local granite and magnifiers for a granite study, looking for colours and large crystals.

Optional:
Show crystal formation with a student crystal painting.
As they work, circulate to help them find crystals and crystals forming, referring to the same process happening deep inside the earth during the formation of intrusive igneous rock. (Do not focus on the water evaporating to form these crystals, as this is not the purpose of the activity in the context of this lesson.)

Referring to the rock cycle drawing, review how all rocks eventually cycle back to the surface, from which they are weathered and erode to wash into the ocean again.
Discuss how many cycles there are in the drawing - there are several different cycles in the rock cycle.

Notes

This lesson used as Lesson 4 of 6 of a series on the Carbon Cycle: 'Rocks back to the Surface'
This is the slow cycle of carbon, as it moves through rocks

Sedimentary sand art

Summary
Make layered sand art from different sand colours, with a discussion of sedimentary rocks.
Science topic (2005 curriculum connection)
Earth and Space Science: Earth's Crust (grade 7)
Materials
  • Sand colours, in separate tubes
  • Small bottles or containers. I have used old cuvettes.
  • Small squares of paper, with a crease in, to use to pour the sand into the container
  • Tape to seal containers
  • Sedimentary rocks with clear coloured layers
Procedure

Students make thin layers of sand in different colours. Tap the container between each layer so that they settle densely.
Once the container is completely full, seal the top with tape, to prevent the sand from shaking around and the colours mixing.

Discuss how sedimentary rocks are formed, and look at real sedimentary rocks to see the layered patterns they make.

Notes

Included in rock study lesson, but better placed in a sedimentary rock cycle lesson.

Rock collection

Summary
Look at different kinds of rocks. Notice their texture, patterns, colours. Discuss their place in the rock cycle.
Science topic (2005 curriculum connection)
Earth and Space Science: Renewable and Non-Renewable Resources (grade 5)
Earth and Space Science: Earth's Crust (grade 7)
Materials
  • collection of various rocks e.g. sedimentary rocks showing layers, lava, mica, crystal, rocks containing metal ores
Procedure

Look at and touch the different kinds of rocks and discuss how they are formed.

My collection:
extrusive igneous - basalt (from Vancouver beaches), obsidian and cinders (from Oregon lava lands)
intrusive igneous - granite, pink and grey (from Vancouver beaches)
metamorphic - marble (offcuts from stone countertop store)
sedimentary - sandstone and mudstone (from Vancouver beaches)

Note: it is very hard, just by looking at a rock, and unless one is more expert, to determine whether a rock is sedimentary, metamorphic or igneous.

Notes

Rework to make more interesting.

Rocks: geodes

Summary
Break open geodes to find the crystals inside.
Science topic (2005 curriculum connection)
Earth and Space Science: Earth's Crust (grade 7)
Materials
  • geodes. Note that some are much better quality than others
  • hammer
  • old chisel if the geodes need to be opened cleanly
  • old sock
Procedure

To break the geodes into many pieces, put one in a sock and hit it with a hammer. This will make many small pieces, that can be shared among students.

If there are more geodes available, and each student can take home a larger piece, you can try to break the geodes open by breaking them into just two or three pieces using the chisel and hammer.

Magnetic race track

Summary
Use a magnet to pull a car/boat/luge sled along a race track.
Science topic (2005 curriculum connection)
Physical Science: Force and Motion (grade 1)
Materials
  • image of a race car or other racing vehicle (e.g. boat for ice racing, luge) glued to a coin (test coin is attracted to magnets)
  • race tracks printed out and taped to cardboard (not to thick - the magnet needs to work through it
  • magnets, one per racing vehicle
Procedure

Put a magnet under the card below the car or cardboard car/boat/luge etc, and move the magnet to drag the vehicle along, following the track.

Discuss the pushes and pulls: the magnet pulls on the vehicle through the board to hold it to the board. As the magnet is moved the vehicle is pushed and pulled around the track.

Students can design their own race tracks.

Metamorphic animals Life cycle cards

Summary
Put in order cards of life stages of metamorphic animals.
Science topic (2005 curriculum connection)
Physical Science: Force and Motion (grade 1)
Materials
  • cards of drawings of animals in different stages of their life cycle e.g. frog, butterfly, wasp, barnacle, starfish, jellyfish
Procedure

I am giving you animal life cycle cards.
There are 4 different animals in your set, with four different stages of their life cycle.
Try to place the cards into four separate life cycles on your mat, so the arrows link each stage in the life cycle - start with the egg and cycle through two stages to the adult.
Some will be easy as you have seen them before, some you’ll have to guess. Don’t worry about getting it right, but look at the variety of life that goes through metamorphosis.

Discussion:
Barnacle is a crustacean, related to shrimp and crabs. Barnacle egg grows into a larva, which swims in the ocean. The larva develops into a cypris, which settles on a rock and metamorphoses to form the adult.
Crustaceans: some release fertilised eggs into the water, others hold on to the eggs until they hatch incl. barnacles. Larva called nauplius.
Jellyfish: Egg grows into a swimming larva, which attaches to a rock. Metamorphosis to form a polyp. Young jellyfish bud off. Eggs fertilized outside the parent. Larva called planula.
Starfish/sea star: The eggs grow into a swimming larva, which attaches to a rock, goes through metamorphosis to form a juvenile starfish, which grows into an adult. Eggs fertilized outside the parent. Larva called bracholaria.

Plankton
Show plankton images e.g. from https://plankton.photography/
Show larvae image and find ones like barnacle and starfish larva.
They are tiny and drift with the ocean currents. Plankton are food for other larger animals.
The adults make many young so that some survive to the next stage.

Bees: honeycomb art

Summary
Make a tissue paper stained glass window in hexagon shapes, arranged like a honeycomb. Put up in classroom windows.
Science topic (2005 curriculum connection)
Life Science: Characteristics of Living Things (grade K)
Life Science: Needs of Living Things (grade 1)
Life Science: Animal Growth and Changes (grade 2)
Materials
  • hexagons of tissue paper, many colours, about 20 per student (use template)
  • letter sized pieces of contact paper with one corner pre-peeled, one per student
  • tape
Procedure

Remove the backing from the contact paper and tape it, sticky side up, to the table in front of a student.
Students stick hexagons of tissue paper to the contact paper, arranged as a honeycomb (or not). Tell them that once the tissue paper touches the contact paper it is impossible to get up again without tearing it.

It can be hung in a window as "stained-glass" art.
