2. Plant growth and development
A 8th Grade inductive lab to integrate
content knowledge with
experimental design
Students will design a lab to answer: What factors influence plant growth?
3. The Challenges
Over a 3 week period of time, 8th grade students may encounter:
• How can I identify the
independent and dependent
variables of my experiment?
• How can I control the
experimental environment?
• What measurement
appropriately reflects the
changes in the dependent
variable?
• How can I best present my
data to my peers?
4. What data will be collected?
Students will
determine the labels on the
Day of Plant Height (cm) charts and graphs to increase
Growth rigor

Lab Assignment: Make 3 solutions (0.1 M, 0.4 M, 0.7 M) of Kool-
Aid and decide which tastes best!
1. Create own procedure
Which variables can be measured in the lab? Which
cannot?
What unit conversions would have to be made?
What equipment to use?
2. Create own data table
Calculate % error and explain sources of error.
3. Create graphs in excel with trend lines.

10. What type of data will we collect?
• Students will collect actual data representing
the results of crosses they perform (data
collected will vary based on hypotheses)
– Frequency of genotypes
– Frequency of phenotypes
• They may also choose to use Punnet Squares
to compare the actual results of their crosses
with the probability of those results
• We will analyze the data using graphical and
statistical methods, as appropriate
11. Angles of the Sun
• Students will collect data from different
locations on Earth
• This data will be put into a spreadsheet and
used to make graphs, charts, and answer
questions
12. • Data from 5 locations on Earth (Latitude,
Longitude).
• Angle of elevation for each location at 4
different times of year
• Clock time at solar noon (when the sun is due
south at a given location)
• The relevance is answering the question of
why we experience seasonal variation
13. Chemical Reactions Learning Segment
Auburn James
Laboratory Theme Engaging Students
• Chemical vs Physical Changes • Encouraging students to
– Students hypothesize, view reactions/changes from
observe phenomena, then everyday life through a
learn concepts and definitions scientific perspective
and how they are applied • Using critical thinking and
problem solving to interpret
• Types of Chemical Reactions observations to piece
– Students first observe four together the curriculum
types of reactions, use inquiry “facts”
to determine what is • Experiments are hands on
happening and kinesthetic
– Observations lead to
discussion/lecture learning the
four types of reactions

14. Chemical Reaction Learning Segment
Auburn James
Reaction Rate Determination Reaction Rate Observation
• Students react Alka Seltzer • Temperature probe monitors
tablets in H2O progress of same reactions
– Time reaction based on a – Use same reaction
provided procedure conditions as before
– Manipulate any variables – Connects rate to enthalpy,
they choose in 4 more trials exothermic vs endothermic
to determine what affects reactions
reaction rate – Reaction is complete when
– Combine class data and temperature stabilizes
determine mathematical – Students compare
relationships between 3 temperature data to data
variables and reaction rate collected before
15. • Hudson River discharge unit is used primarily to serve as a post assessment
summary comparing weather and climate variables and how they interact in a
local setting. Additionally it will have students consider human influences on the
river. It will have students hypothesis and prove what natural factors influence
the discharge rate of the Hudson River at various locations along it’s length
throughout the year.
• Students will gather data from
http://maps.waterdata.usgs.gov/mapper/index.html a government site, and
http://www.weather.com/ a commercial site and compare ease of use and
abundance of data to create spreadsheet and climographs based on sites
along the river.
16. Student Challenges of the Unit
Students will have to think creatively as well
Engagement as analytically while gathering records from
the USGS sites.
• Students will be engaged Many of the gages that students will want to
because the bulk of the use have been discontinued due to lack of
data they gather will be funding, or have daily rather than monthly
based on locations they averages. Students will have to evaluate the
know and choose usefulness the data they wish to incorporate
themselves. into their spreadsheets.
• USGS.gov uses Google Students will have to use knowledge of
Earth skins where students geography, climate and weather of NYS to
come up with an explanation for their data
can “fly” to gages and
and hypothesis.

Additionally students will compare a

Hinweis der Redaktion
In this lab, students will design models of dragon “chromosomes” and “cross” their dragons to observe the genotypic and phenotypic outcomes. They will be mimicking the work of scientists like Gregor Mendel, who used peas as a model organism to test hypotheses about heredity. This would take place on Day 2 of the heredity unit – on Day 1, students would complete a guided reading to learn about the work of Gregor Mendel and introduce themselves to some key genetic terms: allele, genotype, phenotype, dominant, recessive, heterozygous and homozygous. Students would have already completed the unit on molecular genetics and sexual reproduction, so they would be familiar with key events of meiosis, the concept of a gene and its location on a chromosome, and how DNA/genes function in genetic inheritance. The purpose of this lab is to help students construct an accurate schema of things like dominance, heterozygosity, and the relationship between genotype and phenotype. Throughout the lab, they will also discover/model key genetic principles: segregation of alleles during meiosis, independent assortment, and linkage. Finally, they will get a better understanding of how/why scientists use models/model organisms to test certain hypotheses.
Engagement:Mythical creatures – appealing to students of many different cultures (dragons are a part of myths of many different cultures), pictures available for students who may be unfamiliar with dragons – could alter to use another mythical creature (e.g. Pegasus, gargoyle, unicorn) based on interests of the classOwnership of traits – as a class, they will decide what traits they want to study for their mythical creatures (e.g., fire-breather vs. non-fire-breather, wings vs. no wings, pink vs. green skin, etc.). They will then arrange those traits as genes of chromosomes.Test their own hypotheses – once the class has “mapped the genome” of the dragon population, students will be able to determine what genetic hypotheses they want to test and determine what organisms they want to use for the P generationConnect to work of real scientists – sometimes students feel that the work they do is “silly” or “pointless” because it’s not “real” – i.e., they are using popsicle sticks as chromosomes of imaginary creatures. I will work to combat this feeling by stressing that scientists use models on an everyday basis to study things they can’t study directly (for ethical, monetary, or other reasons). I can remind students that Gregor Mendel used pea plants for his studies not because he wanted to, but because they were readily available/cheap, easy to raise/breed, and had a practical purpose (food source). I can also remind students of work being done everyday on fruit flies – not because fruit flies are particularly interesting, but because they can serve as a model for other organisms (even humans, to some extent).Challenging:Students have to develop their own hypotheses. They have to decide how their materials can effectively model what happens during meiosis/sexual reproduction. They have to choose what crosses to perform and why (how does it help them answer their question?). They have to decide how many repetitions are necessary for the validity of their experiment. They have to critically evaluate their own and other students’ work.
After individual analyses have been conducted by groups (likely consisting of creating ratios or graphing data), class data will be aggregated to look for genetic principles. For example, if two traits are on the same chromosome, the phenotypes will be “inked – e.g., if the trait for breathing fire is on the same chromosome as the trait for wings, then knowing something about whether or not a dragon breathes fire should also tell use whether or not the dragon will have wings (because the traits are inherited together). On the other hand, if the trait for breathing fire is not on the same chromosome as the trait for wings, the traits should assort independently, meaning knowing something about whether or not a dragon breathes fire has no predictive value for whether or not the dragon has wings.
