This lesson plan is for a 1.5 hour lesson introducing 3rd grade students to the water cycle. It includes 6 activities: 1) watching an educational video on the water cycle, 2) completing a worksheet about the water cycle, 3) creating individual diagrams of the water cycle, 4) labeling a water cycle diagram in pairs, 5) explaining the water cycle in groups, and 6) playing a water cycle game in pairs. The teacher reflected that the students engaged well with the lesson, though speaking English took some adjustment, and suggested creating more science lessons in English going forward.

Unit Plan - Year 10 - Big Ideas of ScienceAndrew Joseph
A unit plan currently being implemented in a school on the north side of Brisbane. The unit sticks closely to the curriculum, with lessons to give students experience in a variety of research and presentation modes, culminating in a presentation as the formal assessment. The presentation must follow the progression of one of the big ideas of science through history,from its inception to our current understanding.
This is a scrapbook from a day organised by 157 & IFL. Delegates were managers, teachers and learners from Further Education in the UK. The day was designed to share insight, identify challenges and build ideas for "how to enable great teaching & learning?"
Performance-based tasks allow students to show their knowledge and skills in a more authentic way than paper tests. Integrating technology, such as creating Web pages, virtual posters, and using Google Classroom, will prepare students for their future studies. Participants will learn how to design highly engaging performance-based tasks and rubrics to assess students’ knowledge in Chinese language, science, and social studies units. Participants will get a number of ideas on how to implement performance-based formative and summative assessments in the immersion class. Participants will see videos, pictures, and student work samples demonstrating how two Chinese teachers use short plays, foldable books, living museums, etc., to assess students’ knowledge.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
2. INTRODUCTION
• This lesson plan has been created to be applied with
students of 3rd
grade of Primary in a session of 1 hour
and a half.
• In this case, we only have 14 students since we split
the whole group in two.
• They are not used to study Science in English.
3. BACKGROUND INFORMATION
Students in the class have done some preliminary work on
the topic. During the previous lessons, they have explained
what they know about water and water cycle, they have
learnt and done some experiments about the changes in the
state of water.
This lesson plan is an introduction to the water cycle, so after
this session, they are supposed to do a wider research on the
topic by creating a poster, giving mini-presentations,
studying how much water they spend and waste at home
and analysing their results.
4. LEARNING OBJECTIVES

10. REFLECTIONS ON MY PROJECT
After applying my lesson, I can say that I am very happy about it. It was
sometimes hard, because students are not used to study Science in English
and, at the beginning, they were speaking Catalan instead of English.
But then, when they understood it was important to speak English, they
created really nice group dynamics and the activities were very
interesting.
Firstly, they watched the video: the fact that it was funny made it easier for
them and they enjoy it a lot.
Secondly, we went through all the worksheet about the water cycle. We
created some pictures on the whiteboard to make it clear and a lot of
gestures to help to their comprehension.
Thirdly, they individually answered the first activity. It was a little bit difficult
to understand what they had to do exactly. After some explanation, they
could do it very well.
11. After the individual activity, they worked in pairs to complete a diagram. It
was very difficult for them, so at the end, we did it together. Some of the
answers they filled were right and some were very wrong. At least, they tried
it hard. I am sure I am going to change this activity and make it simpler.
Before playing the last game, they worked together in group of 7 to create a
text to explain the water cycle. They had some sentences to help them
creating the text. It was a good idea to write the sentences. Without them, I
think they hadn’t been able to create a text.
The last activity was playing the Water Cycle Game with the computer and in
pairs. They enjoyed it a lot. It was difficult to understand some of the sentences
it appeared in the game, but the instructions were clear. I was going around
to help them understand the parts they didn’t understand.
I am looking forward to creating more Science lesson plans in English, because
it was easier than I though. They loved it because it was something different
and challenging. I think next year, we could do one or two complete Science
lesson plans in English.
