Procedure:
1. Place 3 of the same beads on table in a completely dark room.
2. On top of the beads place a red film.
3.then place a UV light on top and wait for bead to absorb the light(30-45sec)
4. Take a picture of result after 30-45s
5. Repeat step 1-4 with green film and blue film
6. Compare the beads with the other beads.]]> 2022-04-06 01:07:33 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2131714577 ess11330g3 https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2131730954 Idea: To check the effectiveness of different sunscreens using uv beads.

Add-on Idea: To find out the difference between sunscreen and sunblock.

Hypothesis: The slower the uv beads change colour, the better the effectiveness of the sunscreen blocking out the uv rays.

Materials needed: Three different types of sunscreen with the same spf & uv beads.

Method:

1) Apply a layer of the different sunscreens on each of the uv beads.
2) Place the uv beads under the sun for a fixed period of time.
3) The bead that changes colour the slowest has the most effective]]> 2022-04-06 01:19:05 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2131730954 Hypothesis ess09978i https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2131735126
The colours of the shirts affects the absorption of the uv light.

The darker the colour of the material, the slower of the absorption of the uv light.

Steps
1. put the beads under shirts of different colours.
2. wait for 10 minutes]]> 2022-04-06 01:21:59 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2131735126 Task 2- erina, veronica, jovan, terrence ess73922b https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188581452 2022-05-18 01:30:52 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188581452 Task 1 cjmin https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188582715 2022-05-18 01:31:52 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188582715 group 9 KamZhiXuen https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188583489 task 3]]> 2022-05-18 01:32:30 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188583489 Task 1 ess31402g https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188583509 2022-05-18 01:32:31 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188583509 Task 4 https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188583949 2022-05-18 01:32:48 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188583949 Task 3 fhafha https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584303 Jordan , Rysen , Erfha , Racheal]]> 2022-05-18 01:33:04 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584303 4 ess72290g https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584581 2022-05-18 01:33:14 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584581 Group 7 wanruhere https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584766 Task 2]]> 2022-05-18 01:33:21 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584766 Task 1 ess19491i https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584807 2022-05-18 01:33:23 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584807 Group 10 koe_qin_xuan_gisele https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584903 2]]> 2022-05-18 01:33:25 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2188584903 Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops, without soil, by using water-based mineral nutrient solutions in aqueous solvents. Terrestrial or aquatic plants may grow with their roots exposed to the nutritious liquid, or, in addition, the roots may be physically supported by an inert medium such as perlite, gravel, or other substrates. Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can affect rhizosphere biology and physiological balance of the nutrient solution by secondary metabolites.The nutrients used in hydroponic systems can come from many different sources, including fish excrement, duck manure, purchased chemical fertilizers, or artificial nutrient solutions. ess73922b https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2231159601 2022-06-27 06:02:54 UTC https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2231159601 What is in industrial effluent and domestic waste water? ess05637j https://padlet.com/ess00454e/2n9abe5sk7u07xhg/wish/2244784653 The main thing in effluent water is grease and oil, metals, detergent(but a Low amount).

Some of these materials can be reused and recycled by a recycling center. If you don’t have a comprehensive waste management plan that includes recycling, your waste disposal is not going to be as cost-effective or environmentally friendly as it could be. A recycling center can process the majority of industrial solid waste, effectively reducing your waste disposal costs.
