Science Fair Tips
Wed: problem questions, independent and dependent variables
Thurs: hypothesis, control, constants, materials
HW: Plan out your procedure
Here is an example (Szymon's experiment)
Problem: What amount of water is best for keeping a cactus alive for four weeks?
IV: amount of water (3 mL, 6 mL, 9 mL)
DV: number of needles dropped from cactus (sign that its unhealthy)
constants: same cactus plant type and size, same location, same time frame for monitoring growth, same growing environment, same temperature water added
control: cactus with no water ( 0mL)
Hypothesis: If I give a small cactus 6 mL of water, then it will be healthy and survive for four weeks without losing too many needles because cacti do not need much water to survive, but too much water can kill them.
1. Gather materials.
2. Set up four cactus plants on a tray on the
kitchen table.
3. Number the plants 1, 2, 3, and 4 with a
sharpie.
4. For plant 1, add no water. This is the control.
5. For plant 2, add 3 mL of water (fill a cup from the sink) using a pipette. Measure the temperature of the water if possible.
6. For plant 3, add 6 mL of water.
7. For plant 4, add 9 mL of water.
8. Let the plants sit on the kitchen table for
4 weeks.
9. After each week, or every Thursday, count
the number of needles that fall from the cactus and take a picture using an iphone.
Label the week as week 1. Check the soil, color of the cactus, as well as count the needles that fall.
10. Repeat step 9 for each of four weeks.
11. After four weeks, determine which amount of water kept the cactus the healthiest and record data.

Last week we did a popcorn demonstration to model and explain the importance of non-renewable
resources Earth provides. We also watched the LORAX by Dr. Suess to examine the
symbolism behind his message.

Reflect on the quote below. Provide examples from the popcorn demonstration
and LORAX chart to explain what you have learned about environmentalism.
Write a 5 sentence paragraph of your thoughts.

Science Fair Project - idea due by March 1
Project due in April
Problem: Which toothpaste gets teeth the whitest?
*google search for population science fair projects! There are tons of ideas!
Hypothesis: If I scrub a coffee stained egg for 30 seconds with crest toothpaste, then it will make the egg white and clear of stains.
Variables
Independent variable- what you change-toothpaste types: crest, organic toms, colgate, target brand
Dependent variable- what you measure- how white the egg becomes- how much coffee stain is removed
How long does it take for different popcorn brands to start popping?
choose different popcorn brands
materials list
procedure- step by step what you do
time how long until first pop
record data
make a chart/graph
take pictures
write conclusion- Popsecret brand starts poppping first! Why?

Be ORGANIZED!
week after the long weekend
Hi Everyone!
Some people have been absent this week due to having Monday and Tuesday off.
Here's what we did in science class:
Wednesday:
we worked on our Earth Resources cover page and emptied our binder of all GP papers. We also did a textbook scavenger hunt of the new text.
scavenger hunt- use the online textbook for this
Thursday:
Popcorn activity- class demonstration about non renewable resources and how they can get used up and cannot be replaced by the earth
answer questions 1-10- this was a graded classwork assignment so you need to make this up!
popcorn demo questions 1-10
popcorn questions answer key
Friday:
LORAX- symbolism-
ex: fake trees in the LORAX represent the future environment if we keep destroying ours in real life
Ex: bottled air and Mr. O'Hare represent the ECONOMY and money- all they want is money
symbolism chart- to be graded!
Have a great weekend! See you Monday!
