Making My Three Piece Puzzle

   We didn't really do any research about the three piece puzzle but the teacher did show us what the Three piece puzzle looked like.

We each got a photocopy from the teacher and copied down onto the other two of the drawings of timber.

We all got three blocks of timber and drew the lines on to it.

The first thing we did was on a plan we drew lines in the shape of the timber then we made small center lines in the middle on the sides. Once we made the lines we had to measure out three shapes the first shape was a capital T a lowercase t and a minus -. Once I finished the measuring I shaded the shapes. The teacher demonstrated one of them with the drills he said to drill four holes in the minus shape and then use a chisel to smooth it out all I need to do now is to use the ban saw to cut out the two T's.

  

Transport in Plants

Aim:To observe xylem tissue and prove that they transport water up the plant.

Equipment: One stick of celery with the leaves still attached, a retort stand, boss head and clamp, a petri dish, water, food colouring, a knife or scalpel.

Method: 1. Make a cut across the base of the celery stalk to expose a new section of the stem.

2. Fill the petri dish with water and add a few drops of food colouring.

3. Place the celery stalk in the petri dish and gently clamp it in place using the retort stand, boss head and clamp.

4. Leave the stalk undistributed for 24 hours.

5. Remove the stalk and clamp from the petri dish. Cut the stem about 1/3 of the way up the stem.

Refraction

Aim: To investigate how light is affected by changing the substance it is travelling through.

Equipment: Ray Box, Power Source, Glass or Perspex Block, Single-Slit ray slide.

Method: Collect the equipment from your teacher, and set them up to produce a single beam of light.

1. Place the glass block in the shaded area below.
2. Place your ray box at the top of the page and shine the beam so it travels along the 10 degree line to the centre of the protractor (this is your angle of incidence,i).
3. Read the angle the light leaves the glass block at (this is your angle of refraction, r).
4. Continue the investigation so you can complete the table opposite.
