Cactus Comparison

Muhammed B, Jibril O

We chose this, because it was easy to grow, re-pot and was an interest to our whole group.The cacti we have is the old lady cactus (Mammillaria hahniana). The project’s point is to see what happens when you put a cactus in different types of soil. The soils we’re using are sand, potting soil, and dirt from our school (Hazel Park Preparatory Academy [short:HPPA]). What we are measuring? The cacti height and color. If anything changes, then we know whether or not different soils can affect it.

Fliter Madness: why does filters affect water

Rico H, Carion T, Jelani S, Jetlee Y

Our project is about filtering water and how it affects the water through our home made water filter.This is important so we can filter dirty and salty water at the same time using any kind of water. This could change a lot because we can receive more water everyday instead of running out of fresh water. We don’t really have to waste that metal and all you need to buy is a soda bottle and cotton balls because the balls require 0.99 cents or $1.88. Soda bottles you can get by buying just a dollar or a bit more. The natural items are just rocks and lots of pebbles

How does air temperature affect bird activity

Asmita B, Diana R, Erika R

We chose this topic because we decided that we could learn more about birds and the air temperature. We also wanted to learn more about ways we could help preserve bird environments. A lot of birds have different adaptations to different climate changes.

Macroinvertebrate abundance compared to puddle size

Brandon Y, Lor T

Microinvertebrates can live in many aquatic habitats. We took samples of the puddles that we saw around our school. Macroinvertebrates can adapt to anything that has water. They can eat smaller things like plankton and other smaller insects.  Microinvertebrates can live in ponds, rivers, lakes, puddles and other aquatic habitats.  We observed some familiar microinvertebrates, like copepods and water fleas, and some other ones that we never saw before. Our procedure was to go find puddles and ponds around our school grounds, get samples, bring the samples back and use a microscope to see the macroinvertebrates and microorganisms and draw how they look like. By putting our data in tables, we will determine if the numbers of macroinvertebrates is related to puddle size. (Results pending)

Splash! Comparing the pH of various water sources around us

Angela N, Angelyna T, Bronita B

How do the chemicals in pond, tap, bottled, boiled, aquarium, and soapy water affect the pH level?  The pH is a measure of acidity or alkalinity of water substances, and it stands for potential of Hydrogen.  Some types of water are acidic, and some are basic. These types of waters are what living beings use. It isn’t healthy to use overly acidic or basic water.  In this experiment, water samples were collected from a pond, sink, and water bottle. A universal indicator solution was used to find the pH value. The pH values were determined and recorded. Observations and comparisons were made (results pending).
