What project crimson is: Project crimson is a trust that protects pohutukawa and rata. The pohutukawa is so endangered that there is only five percent left from before. Threats: Threats are mainly possums. A single possum can destroy an entire pohutukawa in 2 years. Habitat:​ Pohutukawa live in hard, barren ground. They grow very well when there are no other plants growing in that place. //Metrosideros excelsa// is the pohutukawas sientific name. They grow up 20m high. Pohutukawa trees grow in a dome shape. Pohutukawa are evergreen trees.(Green all year round.) A giant Pōhutukawa at Te Araroa on the East Coast is reputed to be the largest in the country, with a height of 20 metres and a spread of 38 metres (120 ft). Pohutukawa can cling onto nearly vertical cliffs.

Red Cabbage Juice pH indicator Make your own acid/base indicator by boiling red cabbage. Use the juice to pH different fluids. 1. 1/2 head of *red* cabbage or so. 2. Metal grater. 3. Pot filled with enough water to cover the grated cabbage. 4. Strainer 5. Some acid/base solutions: for an acid try vinegar, for a base - mix some detergent in water. Be careful with the fingers when grating the cabbage. 1. Grate the cabbage into small pieces and place them in the pot + water. 2. Boil the mixture for 20-30 minutes, until the liquid turns a dark purplish color. 3. Decant the fluid into a glass or jar, pouring through a strainer to remove the cabbage. Save the cabbage.. mix with a little vinegar and you can eat it on hot dogs, etc.. The collected fluid should be bluish/dark purple in color. 4. Make up some 'test' acid/base solutions. A good acid to use would be white vinegar. You could also try soda water/sprite or diluted juice from a lemon or orange. You can make a basic solution by mixing some washing detergent in water, or by adding some baking soda (sodium bicarbonate) to water. It's useful to have a **control** solution of (neutral) water - distilled water is best if you have access to it. 5. Add a few drops of the cabbage juice to your solutions, and note any color changes. The juice should turn pink in acidic solutions, and green in basic solutions6. 6.You can use the indicator on any other solutions of interest, or try drying it on coffee filters to create a simple form of "pH paper."
